Scot’s Got Some New Toys for his GSX

RRE’s tuner Scot Gray is dialing up the cute on his built motor. We had his valve cover and intake manifold gloss black. We topped off the valve cover with the RRE Hot Dog Grille plug wire cover in brushed aluminum finish. With what we learned from when Justin powder coated his valve cover last year, we made sure nothing got inside the valve cover when it got sand blasted to clean it up. The intake manifold also got a thorough cleaning inside before installing it.

Scot picked up a carbonfiber hood from Carbontrix next door. Carbontrix also set him up with one of our hood scoops in carbon. We cut it into the hood to grab the hot air coming off the radiator and turbo just ahead of the valve cover.

SCC Magazine – 2002 Ultimate Street Car Challenge: Mike’s on the Guru Panel

Sport Compact Car Magazine, March 2002
Reprinted with permission

There’s no quicker way to discredit your work than to show it to an engineer. Our panel of technical gurus consisted of Mitch Terry from AEM, Chris Weisberg from Magneson, Mike Welch from Road/Race Engineering and Jason Kavanaugh, a talented engineer who’s currently between jobs.

Our panel poked, prodded, admired and criticized the cars from every angle, evaluating the engine, drivetrain, suspension, brakes, body and interior for functionality and quality of execution. Then they came up with an overly complex scoring system that we won’t repeat here (because we don’t understand it) and rated them.

It was little surprise Tod Kaneko’s spotless Datsun 510 found itself at the top of the pile, but the number two finish of the Mustang raised eyebrows. Apparently the purposeful build-up of the Ford impressed our judges. Everything is focused on speed and reliability on the drag strip, with no effort wasted on frivolous modifications.

The Sentra scored a close third, thanks to its very sano turbo system and thorough performance-oriented approach to all the mods. Criticism from most of the judges focused on the disco paint job and the stock interior.

At the sad end of the score sheet was the largely unfinished and hideously complex MR2. Upon gazing unto the Toyota’s cramped engine bay, Mike Welch noted “For every cool part, something else is rigged, hacked, twisted or leaking.” These guys can be brutal.

The Hyundai, despite its massive performance, disappointed the panel. Most liked the concept, but the crude engine management, stock brakes and under-developed suspension offended their perfectionist sensibilities.

RRE- Rob Tallini – Las Vegas Motor Speedway 11/2001

Back to Vegas we went for another event. This time it was all on the short infield stadium track, no oval action. In attendance were the usual German cars we love to pick on so much. An interesting car that was in attendance was the Porsche Super Cup 996 that won the European Championship this year. Recently purchased for $150,000, this 996 was flawless, big slicks, air jacks, real racecar stuff.

After our “rally” race in Tecate, we went through the entire front end of the car. It looked more like it had been through a season of rallying that a street race. We replaced the engine cross member, the motor mounts, all the suspension and cross member bushings. We found several cracks in the main cross member that we welded up and we had to replace the steering rack. The wheel bearings were shot and we also replaced the axles and CV joints to be safe.

While the maintenance was all necessary, it ended up working against us to some degree. Our Eclipse was again  handling diabolically. Just when we had went softer with the springs on one hand, overall we were now stiffer with all the other improvements. We kept chasing the set up and again decided our set up was too stiff for this track. It was better suited for a fast track like the oval or the big track at Willow Springs.

We qualified 3rd, a real disappointment for Tallini and the crew. Ty, Eric, Bobby and Jose our crew had changed everything possible to correct matters but we were limited by the springs we chose.

Nonetheless, the race went well for us. On the start, Tallini again punked the Porsches and we jumped from 3rd to 1st into the first turn. Tallini led the 2 faster Porsches and a BMW, the class of the field. Holding them at bay for a third of the race, we started to blister a left front tire. Tallini could feel it and could no longer hold back the Porsches. They slipped by in a tight right hander. The three of us appeared chained together, that was when the 996 choked under the pressure. He was leading the pack he ran a little wide in a left hand sweeper. Instead of riding it out, he got greedy trying to get back on the track. Oops! He caught a little traction on the front wheels and with the weight of the rear motor influencing things he shot across Tallini’s bow backwards at about 80 mph backed the beautiful car into the barrier. Now we started getting some game from the BMW. He passed us and we passed him. Both of us were ringing out our cars like a dishrag!! This went for a few laps until we could pull out a little. While all this was going on, the other Porsche slipped away. We easily finished second.

We inspected the car after the race and found that left front tire with about 10 holes the size of a silver dollar in it. Remember the dishrag? All and all we were pleased. We had competition, learned more about our racecar and brought home another trophy. Testing is in order now. We need to soften up the springs some on the tighter tracks in order to get the car back to it’s old self.

RRE – Rob Rallini -Tecate Grand Prix 2001

After our triumph in Vegas, we headed south of the border to Tecate. This event is entirely different from races we do in the U.S. The track is a temporary street course approximately 1.9 miles in length. It is rough, dusty, and unforgiving. We again brought our 1G Eclipse. Many other gringos from the Porsche Owner’s Club, Touring Car Club, and NASA joined us. Having previously dominating our Group A class in the Border series, we were nicely “invited” to run our car in Open Class from now on. Open Class is just that, anything goes.

The primary change we made to the car was all new JIC shocks and springs. Our old suspension had a lot of mileage and it was time to upgrade to something more current. The weather was mild by comparison to Vegas so we felt confident with the engine as it was set up. Suspension tuning was our primary concern.

Tallini went out for practice and returned shaking his head. The track was so rough and the springs we were given so stiff, it made the car undrivable on what was effectively a paved rally course. “The car is always off the ground!” Tallini said. Literally, as there were two “yumps” on the front straight away. We worked frantically to soften up sway bars and tire pressures in order to minimize this problem before qualifying. Since we weren’t the only ones dealing with the rough track, all the teams were busy dealing with suspension set up.

Qualifying was uneventful. We did our usual routine of hiding from the competition, laying down a few fast laps, and then sneaking up behind them in order to size them up.  Tallini came back with second overall fastest time. One of the POC Porsches, Dino Casamasima, had put down a time a whole second faster than us.  We felt like we had a little more car left but we were afraid we might break something in the driveline. We thought it was prudent to save the car for the race on Sunday.

 

Warm ups in the morning should have been uneventful, but after 3 laps Tallini pitted with smoke pouring out from under the hood. We broke the turbo oil return line (rally style) and fortunately had a spare in one of the rally boxes. No problem.

Before the race we discussed how to handle our pole sitting Porsche.  We decided, go for the win or break trying. Standing starts usually work to our advantage. On the outside of a staggered front row, Tallini launched hard on the Porsche and beat him into the first turn. Nose to tail for laps, the Porsche kept taking stabs at us and even got past in the braking zone at the end of the front straight. Tallini immediately worked him over and retook the lead. The race was turning into a gladiator match. Unfortunately for Porsche, we hired a meaner Italian and the gladiator match was over. After squeezing each other in the braking zone, Dino ran wide, clipped a curb and developed a leaking right rear tire and he slowed. SET, MATCH, GAME!

We smoothly sailed home to victory. With thousands of spectators lining the track. Tallini took Welch for a victory lap and saw first hand just how rough it really was. They love us in Mexico!!  Fan clubs, Tecate girls, appreciative people, Mexico has it all. We can’t wait to go back.

Our friends from Open Track Ryan Flagharty and Gus Heredia also ran their 4AG Corollas in the Group B class. Gus won Group B.

RRE- Rob Tallini – Las Vegas Motor Speedway 8/2001

 

We couldn’t resist the opportunity to run with NASA and the PRO Racing Series on the American Le Mans Track at Las Vegas Motor Speedway. Unfortunately, August in Las Vegas means triple digit temperatures. We went for it anyway in our 1G FWD Mitsubishi Eclipse.

There were quite a few Porsches and BMWs in attendance as well as a variety of American muscle cars. Cars ranged from Porsche 996 and 993 ALMS cars to Southwest Tour Cars. We ran in the under 3.0 liter anything goes class.

Practice and Qualifying were quite the challenge due to the heat. Our driver Robert Tallini had never driven this track so he paid close attention to finding the fast way around the oval. We played with sway bars and tire pressures in order to optimize the temperature in our Toyo tires. We slowly dialed in suspension while at the same time, data logging engine vitals.

The 110+ temps in Vegas made dialing the engine in even more important than suspension. Qualifying went well and we had the pole in under 3.0 liter class (7th overall). Closest were a pair of BMW M3s. We were happy with that but Tallini knew there was more left in the car. We made a few more adjustments and prepped the car for the race.

Inside the 4th row the start proved to be a revelation. When the green flagged dropped, Tallini passed 3 cars into the first chicane. Typically we get good starts but we were amazed at the couple hundred thousand dollars worth of German hardware we passed. All race, three Porsches (a 996, 993 and a RS2) chomped at our heels.

Tallini said he spent more time looking backwards than forward. Every lap we thought we would get out powered down the straight. Not the case. Every lap we thought we would get out braked at the end of the straight. Never happened. For a half hour all eyes were on us. People couldn¹t believe a Mitsubishi could beat up all these purpose built race cars with double the horsepower and big slicks!

As the race wore on, Tallini kept us leading our class by 12-15 seconds and battled for the overall podium. Near the end of the race, tire temps soared and the car got harder and harder to drive. After a series of tight turns in the infield section our new German friends got within striking range and one struck. In the entry to the hairpin he got in under us and pushed Tallini out to the grass. With 2 wheels in the grass we lost the drive out of the corner and the Porsches slipped by.

Fortunately, a couple of DNFs in front of us allowed us to finish 4th overall and of course we won our class by 14 seconds. Tire wheel temps were so hot that the valve stem caps were melted to the valve stems. We were pretty stoked afterwards and more than a couple of German car owners actually came up to shake hands. They were impressed with our Mitsubishi Eclipse and perhaps a bit embarrassed by us.

RRE 2G Eclipse SS Clutch Line Instructions

2G Turbo Cars (95-99)

The RRE SS Clutch line replaces the Rubber flexible line that runs from the frame rail under the fuse box down to the transmission. On a 2G car, it also replaces the reservoir that is bolted to the front of the transmission.

Unbolt the fuse box so that is can be shifted to the side. Crack loose the 10mm flare nut to the stock hose. After it is cracked loose then remove the clip that secures the hose end to the bracket with pliers. Unbolt the reservoir from the transmission by removing the 3 12mm head bolts. Remove the banjo bolt to the slave cylinder.

Here is a pic of the stock hose / reservoir / line assembly once it is removed.

Install the new line using the supplied banjo bolt and new crush washers. You will need to bleed the clutch fluid of all air in the lines. Use any brake fluid for the clutch hydraulic fluid. Check for leaks.

When installing the SS Clutch line, you have the option of removing the clutch fluid restrictor. It is a small plate with a  .050″ hole in it that slows down the release of the clutch. Mitsubishi put it in there to help make clutch release smooth and slow. If you want it to release faster than you have now, pull it out.  Our suggestion is to try your clutch with just the new line first. If you want more grab than that, pull the restrictor too, just be careful what you wish for.

This is a pic of the restrictor being picked out of the hole once the banjo bolt has been removed.

This is the restrictor once it is removed

While you are down there replacing the clutch line, also check to see if the slave cylinder is leaking. Pull back the rubber boot. There should be NO fluid in there. If there is fluid behind the boot, it is leaking past the piston and seal. Most 1G cars and many higher mileage 2G cars will have this problem.

SCC Magazine – Ramada Express Rally 2000

Ramada Express Rally 2000

170 stage miles, one beater rally car and the worlds biggest hammer.
From the February, 2000 issue of Sport Compact Car Magazine
By Dave Coleman
Photography by Dave Coleman

It’s a phrase no rallyist wants to utter.”Uh, Mike, can we borrow a hammer?”Mike Welch, of Road/Race Engineering, has along with his unhealthy fondness for fixing smashed rally cars, the world’s largest collection of rally car repair tools. Among them is The Hammer. The Hammer is a mangled, 60-LB block of lead impaled on the end of a Ford truck axle. We already knew The Hammer. We had seen it back at Road/Race’s shop and had even been known to pick it up just for fun, or point and giggle at the though of actually using a thing to fix a car. We weren’t laughing now.

Welch let us borrow The Hammer, but that was only the first hurdle. Next we had to swing it. The Hammer, when you count the handle and the various pieces of rally car shrapnel embedded in it, weighs at least half as much as the heftiest member of our Eyesore Racing Team.

Before long it seemed we had a carnival barker calling out, “Watch the big hammer swing the nerds!” A crowd had gathered to eye our vinyl topped shoebox of destruction with the mix of sympathy and humor appropriate for its current state. Bent, rally sore, and wheels akimbo, Project Rally Beater was coated with equal parts dirt, glory and despair. The despair was only getting thicker as, one after another, our 160-pound driver, 130-pound navigator, and 130-pound crew chief strained muscle and tendon to gently tap The Hammer against the rear wheel.

Then the crowd parted, and through the gap appeared Bob DeBenedetto. Spectator, rally nut, and easily 300 pounds of solid muscle, DeBenedetto probably could have bent our suspension back into shape with his hands. With a soft spoken “mind if I try?” he picked up the hammer lined it up with the top of the rear wheel and took a swing. The first hit was so hard the car jumped in the air. Dust gently wafted out of every crevice in the bodywork. But most importantly, the top of the wheel moved in about half an inch. He hit it again, and again, and again. “Hit it a little higher, a little farther forward, a little farther back.” With the precision of a laser alignment rack, The Hammer pointed the wheel back where it needed to go.

Back to Welch for another beg. With a welder borrowed from one team and a generator borrowed from another, Welch welded up the new crack in the control arm and that was it. With 10 minutes to spare, our rally was back on track and we were ready for the longest stage in American rallying.

The hammer incident was the culmination of a year’s worth of half-hearted preparation, corner-cutting and making do.

After noting the cheery disposition of a rally driver who had just tossed his car high into a pile of rocks at the 1999 Ramada Express Rally, it quickly became obvious that the true path to rally happiness was not through a WRX or Lancer, but through a Corolla, RX-7, or other suitably disposable beater.

Beaters can be flung against the rocks with wild abandon and then repaired for pennies–or replaced with another beater.

It was after watching this very rally in 1999 that we decided to build a beater ourselves. That we returned to the Ramada Express to race in 2000, however, was unexpected. The Beater’s first official competition was in the Treeline ClubRally, a local event so close to home that we didn’t need a trailer. At that point, the car was barely ready for competition, and the notion of being robust enough to finish a 46-mile rally was questionable at best. The 160-mile, three-day Laughlin event wasn’t even a consideration. But in the adrenaline of the moment, after most of the car proved somewhat durable (we did have a distributor failure that put us into last place for two stages) we gleefully proclaimed “We’re going to Laughlin!” Oh boy.

Of course, this event, officially dubbed the Ramada Express Hotel and Casino International Rally presented by Mitsubishi, is a much larger undertaking than Treeline. Treeline is six stages in one day, Laughlin is 15 stages in three days. Treeline is 47 stage miles, Laughlin is more than 160, with stage 11 alone totaling 45 miles. We had a car, now we needed serious logistics.

First lesson of rally logistics: Don’t make fun of your friends for driving trucks. When our longtime friend Jeff Payne traded in a Impreza 2.5 RS for an extended cab, four-wheel-drive Cummins turbo diesel pickup, we naturally unleashed the full force of our SUV hatred on him. Lucky for us, he has a short memory. You can fit a lot of rally car parts in the back of a Dodge truck, and the Cummins engine doesn’t even notice a rally beater on a trailer. Oh, and about that trailer. What’s an aspiring rally driver with limited parking supposed to do about trailers? We rented one from U-Haul for about $260 for five days.

And then there’s clutch paranoia. It isn’t a universal problem, but it strikes us before any long event. One Lap of America, 1999: Our WRX RA had been passed around to various members of the press for three years, and the clutch seemed to engage a little more softly than it should. Paranoid about a mid-race clutch failure, we talked Subaru into air freighting a new clutch from Japan and installing it one day before the car was shipped to the race. The old clutch, naturally, was less than half worn.

So it was with the Rally Beater. We had installed the engine only a few hundred miles before and the clutch, though worn, was far from ready for retirement. But somehow it suddenly didn’t seem to grab hard enough to give us confidence. A week before the rally, we frantically called Centerforce. Project Rally Beater has a clutch from a 2000 Datsun Roadster, an extremely rare car these days, but Centerforce not only makes a clutch for the Roadster, it was able to have it in our hands in less than two days! Now, that’s a pretty comprehensive product line! Working under a rally beater is an adventure in dirt. Removing the transmission after a rally means enduring an avalanche of gravel and mud every time you touch something, but in a few frantic hours, we had the old clutch out and the new one in. Naturally, the old one appeared to have plenty of life, but the two 30-foot black stripes on the street outside the office suggest the Centerforce is still far stronger.

And then there are the spare parts. At Treeline, we packed light. The only spare part was a distributor, which, as luck would have it, was the only part to break. For Laughlin, we packed everything. Digging around under shelves and behind workbenches revealed a treasure trove of forgotten parts. Spare engine mounts, brake drums, struts, steering linkages, alternators, starters, lights, hoses, fluids, anything and everything was put in plastic bins and labeled for the inevitable late-night repair sessions. Preparation for the rally was an all-consuming effort, mixing equal parts of paranoia and giddy excitement.

Naturally, the preparation didn’t end at getting the car to the event. We still had to unload it and pass tech. Normally, the pre-rally tech inspection is fairly minimal. The harnesses and roll cage were checked, the certification on your helmet and driving suits are reviewed and, because transit stages are often run on public roads, a basic check of headlights, horn, turn signals and brake lights is performed. No sweat, right?

Naturally, after 30 years of working perfectly, the brake lights chose to fail just as we were waved into the inspection. We got through (don’t ask how) and the preparation continued.

Word around the pits was that the first day’s forest stages were covered with snow and mud. Tomorrow was going to be a race of survival. Hmm, used, warm-weather rally tires, an open differential and snow. We stopped thinking about finishing well and started thinking about finishing at all. Five minutes before closing time, we came squealing into the last open auto parts store in town and bought tire chains. Is this an odd sport or what?

Then, we saw Rhys Millen preparing for the soggy mud/snow soup by cutting larger grooves in his nice, new Michelin rally tires. After a quick, tire-grooving tutorial from Millen, we borrowed a tire-gooving iron from fellow rallyist Paul Timmerman and started work on our tired, old Silverstones. Rallies have specific rules mandating when and where teams can work on their cars. In parc expose, teams may work on their cars as they are displayed to the public. However, in parc ferme, the car can’t be touched. Parc ferme began at midnight, and we finished grooving tires at 11:59 pm. The parc ferme rule never made sense before then; without this rule, we probably would have worked through the night.

Stage One

The transit stages for the Ramada Express Rally are huge. All the stage roads are on the Hualapai Nation on the edge of the Grand Canyon, about 100 miles from Laughlin. In previous years, drivers had complained about the fatigue, monotony and tire wear from the long transits, so the rules were changed this year to allow the cars to do the long transits on their trailers.

To make the race look more exciting for the locals, however, all the cars still drove over the start ramps and through town before loading onto the trailers across the border in Arizona. The American Rally Sport Group has a good record of trying to keep the competitors happy and the rally as spectator-friendly as possible.

Expecting mud, snow and slush on narrow forest roads, we pulled up to the start of stage one and saw a dry, hardpacked straightaway. Just before counting down to our start time, the starter warned us that two cars have rolled on this stage. No pressure… Go!

At approximately 7,000 feet, the Beater accelerated reluctantly to a top speed of about 80 mph. On the dirt, with thoughts of cars on their roofs, it still seemed really fast. After a few minutes of driving flat out, the road suddenly narrowed, got wet and snowy, and turned into a hard right. Less than 10 turns into the twisties, we saw warning triangles, an OK sign, and the Audi quattro of George Plsek and Alex Gelsomino tires up in the ditch. It took serious self control to keep the car on the road as we worked slowly up to speed. An upside-down car on the first stage doesn’t inspire confidence. A few turns later, the scene is repeated, this time with Mark Nelson and John Bellfleur’s Mitsubishi Lancer. This was getting ugly.

When we reached the end of the stage, the arrival time control was at the top of a very small hill, and another car was still busy checking in. We waited halfway down the hill, and then tried to pull forward when the other car moved. We tried.

Even on the very slight incline, we just sat and spun our tires in the mud. Just making it to the time control meant backing up and taking a running start. This was an omen.

Stage Two

Everything was brown. The road was brown, the cars were brown, the trees were brown, the windshield was brown. The road was heavily rutted, but the ruts were nearly impossible to see. They constantly tugged the car this way or that, and steering inputs seemed to have little effect in this slime.

The transit to stage two had two-way traffic, with the leaders, having already finished the second stage, coming head-on toward us on their way to the first service stop. Common sense said to slow down, physics said if we did so we’d get stuck, so there we were, flying through the muck, tires spinning, car sliding erratically from one side of the road to the other. Rhys Millen was doing the same, and we narrowly miss slamming head on into him. As our windows passed within inches, we could see the grin on his face was almost as big as ours. Insanity loves company.

The start of stage two was frozen and slick. So slick, in fact, that as Richard Byford and Fran Olson tried to inch forward to the start, their BMW 2002 did a slow, graceful pirouette and ended up stuck sideways in the road in front of us. Several navigators jumped from competing rally cars to push them from the muck.

The weighty slime so thoroughly coated the sides of our car that the stage workers had to ask our car number before recording our times. Our hearty mudflaps, which had survived all our “testing and development” miles without complaint, were ripped from the car after just two stages in the slime.

Stages three through six were more of the same–slimefests of epic proportions. The mud became so thick at one point that full throttle in The Beater produced all of 35 mph. At the end of day one, The Beater managed an impressive 10th overall, slotting in right after the open class Galant VR-4 of Keith Roper and Ray Damitio and sneaking in just in front of the Group 2 Eclipse of Christopher Burns and Steve Westwood. The next day was sure to be harder for The Beater as the roads opened up and horsepower became more of a factor.

Faster it was, though momentum was proving itself a fair substitute for horsepower for a while. Pounding up stage 7 out of the grand canyon, we managed to hold our position despite the need for power. After a brief roadside repair stop to fix some loose exhaust bolts, we started into the real horsepower stages where the fast cars were going 140 mph, and we were going 100. That lead directly to the ditch (see “Great Moments in Rallying #3, to the right.)

Driving fast on treacherous, slippery roads you have never seen requires a certain placidity, a certain Zen calmness in the face of unparalleled pressure. Every road has a rhythm, every car has its special moves, and being in the zone means being able to make the car dance. Try dancing after crashing a car, running a quarter mile with a helmet on your head and the thin air of 6,000 feet in your lungs, after spending five minutes jumping around in a ditch like a couple of drunk monkeys. This is the kind of challenge that separates the professionals from the dirt jockeys like us.

The very next stage, still breathing heavy, and still searching for our rhythm, it happened again. This time there was no glorious almost-save. This time it was simple. We went too fast, turned too late, and slid into a small ditch. A very hard small ditch. This, for certain, was the end of the rally for Eyesore Racing.

This brings us up to The Hammer, but you’ve already heard that one. Finishing the Laughlin rally’s 45-mile Canyon Challenge stage after repairing the The Beater with The Hammer may turn out to be the crowning achievement in our motorsport careers. The Canyon Challenge came at the end of the day as the sun was setting. And, as luck would have it, the stage ran primarily east to west. That meant the pucker factor was high as The Beater blasted over blind crests, directly into the blinding sun. However, this time, it stayed on the road and made it to the end of the second day.

Leg Three of the Laughlin event is held in a huge gravel field behind the headquarter’s hotel. It’s called the SuperStage and is basically a dirt autocross which pits competitors against one another in wheel-to-wheel brawls designed to put a spectator-friendly finishing touch on the event. Organizers match cars which have produced similar stage times on the rally’s previous legs to compete together on the two-lane SuperStage course.

The Beater was matched against the RX-7 of Jim Gillaspy and Mick Kilpatrick who had eeked out a fair lead on us the previous two days. The SuperStage, however, proved how well matched the cars really were as the two were given the exact same finishing time on two of the four stages. Naturally, Gillaspy’s car was slightly ahead on those runs, but a half car length is invisible in rally time. The other two runs were a draw–one win each. Stage 15 brought to an end one of the longest, roughest and highest attrition races in American rallying in the last 10 years.

In the end, The Beater did all right. Somehow, despite all our efforts to throw it away on stages 10 and 11, The Beater won its class (Group 2) and managed ninth overall–not bad given the number of four-wheel-drive open class cars in this race. And the reward for winning Group 2? One thousand glorious greenbacks! Who says rallying doesn’t pay? The ARSG gave away $25,000 in cash and prizes at the awards ceremony after the race.

The organizers of the Laughlin rally have a slogan: “We promise you an adventure,” they say. And given the roads, distance and fun factor of this year’s event, we couldn’t agree more. The Laughlin International Rally epitomizes what rallying should be: Man vs. road vs. the clock. It is, without question, an adventure.

Rob Tallini – RRE Eclipse GST – Tecate, Mexico 2000

The track was pretty cool for a street course. It was in a hilly area based on a divided highway through a slight valley right by the Tecate Brewery. One side of the road went up and curved back down the side of a hill, then to a short straight with a long dip, 90 right, hair pin right, sweeping left back on to the wide road through the valley that curved slightly. Since it took you at a pretty high speed (110-120) down to another hair pin right back onto the front straight, they built a chicane out of tires to slow things down before the hairpin. This tire barrier would get regularly rearranged from cars blasting through them.

Practice

 

Rob Tallini was driving our 1G FWD this weekend. On Saturday Morning, the car started running a little hot. We found one of the flat fans had died, melted solid inside the fan motor. Scot Gray went on a tour of down town Tecate looking for some kind of universal flat fan. Not in Mexico. Lucky for us, our number one race fan in Mexico Pedro Kim volunteered to drive to Pep Boys in San Diego to get one for us. He lives in Tijuana and had driven all the way to Tecate to see us. He has been to every Mexican race we have run and even drove up to watch the LA Street Race. Pure devotion. We just turned the boost down to 1.0 bar and it ran cool enough till we got the fan installed.

Qualifying

We qualified fastest in Group A on Saturday but were a little slower than the faster open class cars. Power seemed a little off even for 1.0 bar and there was a little dark smoke when the car came on full boost. We went looking for a boost leak and found one, one of the Allen bolts to the compressor outlet flange was a millimeter too long and wasn’t tightening the flange down enough. Fixed that up Saturday after the sessions and were ready for the Sunday morning warm up.

We turned the boost up to 1.2 with the overtake boost set at 1.3 for 6 seconds (one of the few working PRofec A’s in captivity) and with new Porterfield R4-E’s the car was pretty much dialed in. We played a little with tire pressures and were ready to race. This time they combined the three fastest groups so we got to play with the faster open class cars. The two fastest were VW Rabbits running 2.2 liter 16 valve motors (one turbo and one supercharged) and weighing 1800 lbs. Power to weight we were about the same and they had a lot less weight for their brakes to slow down.

Race

They started the race groups separately in their qualifying order. We were at the pole position of the second group, standing start. Rob got a good launch on El Coyote in the Mustang (pronounced “Moose-estang” in Mexico) and just squeezed in front of him heading up the hill. As soon as the open class cars disappear over the hill and as Rob is approaching the crest of the hill, we see a huge dust cloud rocketing along the side of the hill and down to the center of the little valley. Red flag all corners, everyone back to the start. One of the open class cars (a 1500 lb Pinto with a XR4Ti turbo motor) was the victim of a little too much enthusiasm on cold tires and cold brakes.

Restart

Re start is a replay of the first one. Rob worked his way through the remaining open cars and up to the back bumper of the lead bunny. They played with each other up to about the 1/2 way point, Rob was a little faster but since they weren’t racing for actual position tried to be nice. He got a little bored and started working on a pass but the Rabbit started blocking, on one drive out of the last turn Rob ended up giving a little “assist” for the Rabbit up the front straight. The car gets hot with no air flow when following close so he let the Rabbit have a little space.

Then bwaaa…pop. It just started misfiring and sputtering. No juice race over. The alternator kicked the bucket. Rob coasted in to the pits. Arturo in the red rabbit went on unchallenged to finish first.

After our strong showing in the last two races we were politely asked if we “wanted” to move our Group A car over to their Open Class. No problem.

Scot Gray’s Eclipse in SCC Magazine – September 2000

RRE tuner Scot Gray got a nice feature in Sport Compact Car Magazine article on his 1G AWD  Eclipse this month.

Double Entendre

In the world of high-performance machines, Scot Gray’s 1994 Mitsubishi Eclipse GSX didn’t get off to a prodigious start.  Formerly owned by a nice, elderly couple from Oregon who purchased the all-wheel-drive car for its snow and ice capabilities, the Mitsubishi lived the life of a sports car-turned-SUV.  Years later, in an anthropomorphized display of automotive hari-kari, the little coupe blew its turbocharger.  Crippled by a bleeding turbo bearing, and incapable of hauling groceries and potted plants through the treacherous Northwestern trails, the Eclipse was put up for sale, eventually falling into more appropriate hands.

Three years later an abridged performance history of Gray’s Eclipse would have you believ­ing that it has made up for lost time. “I upgraded the turbo twice,” Gray confessed.   “The factory turbo performed very well, enabling me to run 13.3 E.Ts in the quarter-mile. Later, I upgraded to a ported and clipped (10 degrees) Mitsubishi 16G turbocharger. This upgrade significantly improved top-end power with only a minimal increase in lag.”

Capable of running mid 12s at the drag strip, all was well until our protagonist ven­tured to Buttonwillow Raceway, overheated the car and warped the cylinder head. Now bitten by the road racing bug, Gray wasted no time in procuring a new factory head. With the assistance of Road Race Engineering (Santa Fe Springs, Calif.), the unblemished head was thoroughly ported and polished. The bottom end, receiving its fair share of attention, was rebuilt with the inclusion of stock 1995 model year 8.5:1 pistons.

On the road, the performance improvements were obvious. Perhaps a little too obvi­ous, as the combination of higher compression pistons and better-flowing heads resulted in a nasty case of boost creep. To remedy the situation, a generously sized external wastegate from TIAL was ordered. But somewhere between the order and the delivery process, Gray decided to up the ante even further.

 “I decided to upgrade the turbo [again] to make full use of the new wastegate.” After a quick long-distance call to Texas Turbo, a “Frankenstein Level 2” turbocharger was on the way. Of course, swapping turbos and wastegates isn’t as easy as it sounds. with different flanges and wastegate configurations, Road Race Engineering had to craft a custom 3-inch down-pipe and exhaust manifold.While all this fabrication sounds like a lot of work, there is no doubting its merits. Empirically, the new turbo should be capable of generating more airflow, with less heat and with reduced exhaust back-pressure levels—all of which translate to more horsepower. However, airflow is useless without sufficient fuel delivery and properly timed spark advance.In an effort to meet both requirements, Gray installed a TechnoMotive ECU upgrade. Featuring a number of welcome EPROM tweaks, this cost-effective upgrade removed the boost and fuel cut in addition to raising the rev limiter. As an added bonus, the stock low-resolution, dashboard-mounted analog boost gauge can easily be configured to mon­itor air/fuel mixture, ignition timing, battery voltage or knock sensor output. Coupled with TechnoMotive’s optional data logging system, Gray is able to tune the car for maxi­mum power with minimal drivability compromises. In fact, despite driving a car capable of whipping off mid-11-second passes, Gray claims to record better-than-stock fuel economy (25/20 hwy/city to be exact).

Like the engine, the rest of the car has been set up with both street and track use in mind. For a clutch, Gray chose a sturdy Advanced Clutch Technology 2,600 ft./lbs. pressure plate with a streetable organic friction disk. To strengthen the Eclipse’s notoriously fragile drivetrain, a Cusco clutch-pack center limited slip differential was installed. Supporting all four corners are GAB Super HP shock absorbers with 2.5-inch race springs and adjustable threaded spring perches from Ground Control. To ameliorate some of the Eclipse’s nose-heavy handling balance, Gray installed a 1.25-inch rear anti-roll bar from Suspension Techniques. And of course, a good road racing suspension wouldn’t be complete without a sticky set of R compound tires.

So how does it drive? Ridiculously well, that’s how. With a 0-to-60 mph sprint taking a mere (and official) 3.8 seconds, Gray’s Eclipse is one of the quickest cars SCC has ever tested. Quite remarkable ending for a formerly pedestrian go-getter.

 

 

Sport Compact Car Magazine – Project Mazda 323 GTX: Part 2

Here is Josh Jacquot’s and Dave Coleman’s 2nd part of Project 323GTX. We no longer sell parts for this car since they have to be custom made on the car in the shop. But since I got my start working on AWD rally cars on the 323 GTX working for Rod Millen back in1990 I always have aspecial sentiment for these little cars.

In this article we helped the SCC Mag guys with the GTX’s suspension, brakes and rebuilding the distributor.

The resurrection of our Mazda 323 GTX project car is still in its infancy as we continue with the essential repairs we began in the first installment. In case you missed out last month, we covered the replacement of the transmission and clutch as well as the basics of a wheel bearing rebuild. This month, we’ll tackle the GTX’s suspension, distributor and brakes, as well as a few less critical aesthetic add-ons.

The GTX’s reliability (considering the regular pounding it receives) as well as its overall capability in the dirt continues to amaze and impress us all. It’s proving itself daily as one of the most fun and most practical cars around the office. While it may not impress anyone with its looks, every time we get behind the wheel, we remember why we had to have a car to play in the dirt.

Springs and Shocks
With what seems like several feet of rubbery suspension travel, the 323 isn’t very much fun when wearing worn-out shocks. This is a real problem and is something the GTX community is tackling in hundreds of creative ways. We aren’t going to pretend that there’s a simple solution either. No one has made new GTX-specific dampers in this country for years. Tokico Dirta struts went out of production several years back and very few, if any, shocks offer the kind of damping control required by the GTX’s long-travel strut system. Cork Sport, an Oregon-based Mazda specialty company still imports KYB struts for the car. However, they aren’t exactly what we were looking for, so the search continued.

Our solution? Buy used. We can’t, obviously, give our wholesale endorsement of this sort of upgrade, but in our case, it has worked fine so far. Given the lack of new suspension parts for these cars, this may be your best option if you decide to follow our lead. The 323 GTX listserv (www.egroups.com/group/323gtx) is likely the best place to look for used GTX parts and information.

Since our infatuation with 323 rally cars began a few years back, we’ve made friends with several 323 owners who race their cars in the California Rally Series and other SCCA events. This put us in good company when it came time to look for used suspension parts. Paul Timmerman (a local racer whose GTXs we featured in the January ’99 issue of SCC) and Road/Race Engineering came to the rescue.

Timmerman had a set of used GAB struts from an old Production GT 323 racecar he was keeping around as race spares. However, since he was planning to upgrade to a custom Bilstein coil-over setup in the near future, the parts that were currently on his car were about be spares. The timing was perfect and we stepped in with the cash. Timmerman gave us a generous price, which didn’t hurt the cause either. The front struts were fitted with stock-diameter rally springs but the rears had no springs. So, despite all our efforts and waiting, our wanna-be rally suspension still wasn’t complete.

Road/Race to the rescue. Naturally, Welch had the solution to our problem in the form of RRE’s coil-over setup. At $400 for all four corners, this reasonably priced setup allows an inch of adjustability–either up or down–from the stock ride height. We only needed half the kit since we already had front springs.

 

Welch chose 150 lb/in springs for the rear of the car, which he figured would complement the rather hefty looking front springs. At this point there was still no real way to know the rate of the front springs without disassembly and we were in a hurry to get the suspension together. Luckily, Welch has enough experience with these cars that we knew his estimate would be better than our guess. We plan to complete the coil-over kit in the future anyway, thereby eliminating the guesswork involved the spring rates. However, since this vehicle will be primarily a dirt car, the precision and exacting demands of dialing in a tarmac set-up don’t exist. If it worked well in the dirt, didn’t bottom out and rotated quickly, we would be happy.

Installation for the rear springs was as simple as sliding the sleeves over the strut body, threading on the collars, dropping on the spring and bumpstops, and then bolting the whole assembly together. We used the stock bumpstops but trimmed off the bellows section.There was still more than an inch of bumpstop to save our GABs from dangerously bottoming out, but with the added travel and increased spring rate, we figured that wouldn’t be a problem (and it hasn’t).

 

The fronts bolted into place with the same ease that everything else on the car had exhibited–rusted bolts, nuts and washers were the name of the game. We managed to get the struts out without breaking anything or rounding off any bolt heads. Fitment of the GAB strut housing required removing small amounts of material from the 323’s upright to achieve reasonable camber settings. This job was easily accomplished with a die grinder and a bit of patience.

Per Welch’s recommendation, we didn’t re-fit the front anti-roll bar after replacing the transmission. Reducing the GTX’s front roll stiffness enhances its ability to rotate quickly in the dirt–something real rally cars do very well. The rear anti-roll bar bushings were destroyed from years of wear and weather so we replaced them with RRE’s polyurethane anti-roll bar pivot bushings and new end links (which use rubber bushings). The original end links and bushings for the rear anti-roll bar had become one with the car after years of weather and wear and required some work with the sawzall and several choice words to remove. The new hardware went into place without any problems and took the slop out of the system.

We were initially quite concerned with the alignment settings of Project 323 GTX and asked our friends at Wheel Warehouse in Anaheim, Calif. to handle the job. However, after they could barely squeeze zero camber (Welch’s recommended dirt setting) out of the front end we were less serious about radical alignment. The problems in the front came from our less-than-precise method of grinding the uprights–a not-so-scientific way to get the GAB rally struts to fit. We simply set the car up to go straight down the road and quit worrying about toe and camber, since we are planning to spend most of our time in the dirt, where these settings become insignificant anyway.

 

Distributor
The GTX uses a mechanical-advance distributor to control spark and therefore suffers the consequences of such a complex design. The mechanical advance springs on most high-mileage GTXs fail, allowing the advance weights to swing into the distributor housing as the assembly spins. The weights then rub against the side of the housing, eventually cutting it in half if, not repaired. They also allow the engine to run with maximum mechanical advance of about 30 degrees BTDC. We found all this out the hard way.

Our car had just about every distributor problem the GTX can exhibit. Not only had the advance springs failed, cutting through the distributor housing and allowing maximum advance at all times, but the advance plate, which rotates on ball bearings had seized, allowing for very little, if any, vacuum advance or boost retard. Yet, through some miracle of God-given grace, the car made it 800 miles from Salt Lake City to Southern California in its initial run home.

The distributor is easily removed from the 323 with only two bolts, several electrical connectors, the spark plug wires and one coil wire. (We guess that’s simple, anyway). Be sure to note where the rotor is pointing upon removal and return the distributor to that position when reinstalling. Also, it’s critical to not turn the engine over while the distributor is removed or you’ll end up spending hours trying to time the engine correctly.

 

Our distributor was removed easily enough, but refused to come apart for a rebuild. We ended up using the most elegant method we could think of for disassembly. Out came the cutting torch and pry bars as Welch pounded, heated and pried until the entire assembly was in pieces. Graceful it wasn’t. But we eventually reached the source of our problems and were able to replace the advance springs and rebuild the advance plate, which controls vacuum advance and boost retard. The new springs (which RRE sells for $7) utilize a plastic reinforcement where they attach to the advance weights–we don’t expect any more problems here. However, due to the broken springs, the weights had worn a hole completely through the distributor housing. Welch patched the hole with epoxy since it wasn’t large enough to cause structural fatigue and began reassembly of the numerous distributor parts. We also replaced the distributor cap, since it was cracked in several places surrounding the contacts.

All the problems listed above are common to GTX distributors, so don’t be surprised if your car exhibits similar failures. We were lucky enough to have all of them. However, despite the many parts and complexity of the GTX’s distributor, it’s possible for most weekend wrenchers to tackle its rebuild. Careful disassembly goes a long way in putting things back together in the right order. Plus, the parts that fail are cheap. If you’re still not up to the task, send your distributor to Road/Race and they’ll handle the job for $100.

Brakes (or Lack Thereof)
Stopping our GTX has been a bit of challenge since this project got off the ground. A mushy pedal is never very confidence- inspiring, especially in a car that will be driven with any enthusiasm. It didn’t take long underneath our GTX to notice the extreme wear on the original brake lines. The lines were cracked and worn, and had a generally dangerous look about them. We figured an upgrade to RRE steel braided lines couldn’t hurt. At this point it seemed safe to assume replacing the lines and thoroughly bleeding the brakes would bring back a stiff pedal. However, after doing so, we soon realized the problems with our GTX’s brake system go beyond simple line replacement.

Welch tells us that it’s not uncommon for GTX calipers to lose some off their free play over time. Apparently, the calipers’ self-centering mechanism seizes with exposure to moisture and dust after years of use. The resulting twist in the calipers causes excessive pedal travel, regardless of new brake lines. So we’ll be treating Project 323 to a caliper rebuild and some new brake pads in the next few months to bring back some solid pedal feel. In the mean time it still stops well, so we’ll survive.

 

Always Accessorize
In our effort to make a reliable and inexpensive rally car, we ran across a few other necessities that we just had to have. What was the one thing that all rally cars had that we were lacking? The answer was simple: Huge, night-killing driving lights.

Toucan Industries stepped up with a set of Super Road Boy 100-watt driving lamps. The lights come with a complete wiring diagram, wires and an on/off switch. Our mounting requirements forced us to mount the giant lights upside down–not the most aesthetically pleasing solution, but this car is all about function, not form. Plus, our mount requires no drilling into the bumper. We used 1 x 1.5-inch box section aluminum as a mounting bracket for the lights. The back of this box section bolted to the original grille mounting bracket at either end of the main grille opening. The front of the bracket bolted directly through the lights’ rear housing–a simple mounting solution, which only took a few hours to assemble. We obviously removed the GTX’s unique grille and replaced it with a section of grillwork we found at the hardware store. The new grill isn’t exactly beautiful (in fact, it’s pretty ugly) but, judging on looks alone, it flows considerably more engine-saving cooling air than the original.

Next Time
Hopefully we’ve covered the majority of the major repairs necessary to keep the GTX in running order as a daily driver. We’re counting on it regularly for transportation and recreation these days, so it’s necessary that it not leave us stranded. Next time we’ll begin with the basic power upgrades as recommended by Road/Race Engineering and hopefully have a few dyno charts from local competition GTXs for comparison. Until then, rally on…

Sizing it up
Assuming you’ve already run across the SCC Rallycross Smackdown story last month, you know how effective a properly prepared GTX can be in the dirt. However, we always want a back-to-back, before-and-after comparison to quantify the effectiveness of the changes to our project cars. Before doing any of the above-mentioned work to the car, we staked off a section of dirt road in the nearby forest and went to work. The road, an unbelievably twisty section of gravel with huge elevation changes, ranks among the best gravel roads any of us have ever seen.

Project GTX bobbed and weaved with engineering editor Coleman clinging for dear life in the passenger seat during our initial runs. Don’t bother repeating this test on your own, as its stupidity exceeds even our grossly skewed limits of sanity. We made the runs again after all the repairs and with the much-improved rally suspension in place.

So, what did all this insanity prove? Mostly that the changing conditions of dirt roads aren’t so good for comparing improvements in rally car performance. Without question, the new suspension, improvements in ignition advance and overall preparedness of the car made it easier to drive and faster in any conditions. However, because of our wet spring and consequent road grating, our test road was in considerably different shape during our second visit. With a much softer surface and more loose conditions our times don’t show the improvement we had hoped for. What they do show, if one looks closely at the raw times (not listed here), is that the GTX is now much more predictable and easier to handle over rough terrain. In fact, the GTX’s ability to devour washouts, ruts, rocks and any other dirt road impediment is simply amazing. Before the upgrades we were operating on faith, now we drive with confidence. See the map and elevation profile on the next page for more details.
