Whopsssssshhhhh!! RRE Shop EVO 8 gets famous in Greece’s “Street Racer” Magazine!!

Street Racer magazine sent Jay Canter to the shop a couple months ago to get some pics of our shop EVO 8 race car. It just came out in their August issue!  We went to the closed refinery down the street and took some beauty shots and also ran the car through Turnbull Canyon for some driving shots. Here is how it turned out. What’s it say about the car? Who knows. It is Greek to me :-P.  -Mike W.

If any Greek readers out there can translate this for us, a prize will be awarded.  Meanwhile, I have done my best to translate through using my otherwise useless Philosophy degree. -James Singer

Toxic Photoshoot! RRE EVO 8 Race Car gets shot!

A Euro magazine sent Jay Canter to the shop recently to get some pics of our shop EVO 8 race car. We went to the closed refinery down Lakeland Rd asked if we could get in to take some pics with the freaky background. With a little begging and a lot of convincing that we wouldnt be doing donuts and generally causing a hazmat response – we got in. After we took some beauty shots, we ran the car through Turnbull Canyon for some driving shots with the car moving.

Looking forward to see how it turns out. I can shoot over the shoulder of these pro photographers all I want and… well with them being professionals and all, my pics look amateur  for some reason :-P

Here are my point and shoot pics:

Greg Collier – 1G Eclipse GS-T – March 12-13, Race Report

By Greg Collier – Diary of first NASA race of the season at California Speedway.

NASA Pro-Racing Season Opener At California Speedway March 12-13

It was a sunny 80 degree southern California day when arrived at the track on Friday morning. We got situated in our garage space and got ready for our annual tech and then do some track testing. This being the beginning of the race season an annual safety inspection of the car is necessary. Technical inspectors check the roll cage configuration, tube thickness and approved padding, dates of fire extinguisher and or fire system, SFI approved drivers suit, shoes, socks, gloves, all in case you have a car fire, 6-point seat belts and window net which have to be replaced every 2 years since Dale Earnhardt’s accident. Then they start on the vehicle inspection checking wheels/tires, steering/suspension, and engine for fluid leaks, no anti freeze, overflow containers, battery secured, so-on and so-forth. You’ve got two or three guys checking every nut and bolt for about 15 minutes. You get your race log-book signed and you’re ready for the season. At any time in the following races of the season they can do a surprise inspection to make sure you didn’t change anything. If they find something you’ll get fined $ and until you pay the fine and fix the problem you can’t race.

With our tech complete we took the car to our garage space, gassed it up, checked the tire pressures, and waited for our track time. We were scheduled for (4) twenty-minute sessions starting from 1-PM that afternoon.
I took the first track session pretty easy. We had just installed new Stop Tech brakes the day before so we had to do a rotor and pad seating procedure. I ran a couple of medium warm up laps so I didn’t have to brake that hard in the turns. Then I ran 3 laps pushing harder each lap until I brought the brakes up to racing temperature. I ran a cool down lap and brought it back in the garage not touching the brakes at all. When your breaking in new rotors and pads if you keep your foot on the brakes after you heat them up you’ll embed the pad on the rotors. I don’t even want to go there…………
While in the garage RRE’s Scot Gray, the wizard of EMS tuning, plugged his lap top into my AEM and made some critical air/fuel and idle adjustments before our next session which was an hour from the first one.

California Speedway Grand AM road course configuration is a 2.8 mile, I’m going to call it 14 turn very high speed race track. Top speed for me on this track has been around 160 MPH. You pick up speed on the front straight and take turn 1 on the oval fairly high, as you approach turn 2 you want to shoot down towards the bottom of the track and sling shot out on the back straight setting up for turn 3 that puts you onto the infield road course. So basically you’re going from 160 MPH down to about 40 MPH to make a hard sharp left turn then hard sharp right turn. It’s so cool!
After going through turn 3 and 4 you have a small straight that approaches a left hand sweeper. I usually start wide on this turn then pull a tight apex on the other side and sling shot way wide right onto another little straight. Pedal to metal you come up to a little quick left and right then hard braking into a very tight right hander (35MPH). Full throttle through a cork screw down a very fast straight away under the Toyota bridge to a ball busting, flat spotting, spin out, sharp right hander which is the beginning of very slow S’s. Once you make it through the S’s it’s a balls out almost right handed power drift back onto the ovals front straight. You immediately feel the down force from the incline of the oval and your instinct is to floor the accelerator pedal. It’s like you knew if you had wings you’d be taking off over the grandstands. It’s frigging awesome!

I ran my 3 other practice sessions with about 30 other cars, flat spotted a brand new Hoosier tire at the ball busting turn just before the S’s, and got the car dialed in for Saturdays qualifying and race. All in all it was an excellent test day.

My Competition

Because my car has so many modifications I run in the Super Unlimited class. This class is usually made up of the biggest, badest, fastest cars in the field. Vision Racing brings their “Rolex” series 996 500 HP and 800HP twin turbo Porsches. There was another “Grand AM or Rolex” series Porsche, a yellow custom fiber glassed body full race 911 SC pushing about 350 HP, and a new twin turbo Nissan Z who won a past SCC time trial. Now we’ll get to the fast cars, next to me in the garage was 2300lb. 750 HP tube framed Corvette Z06, a “Trans Am” series 700 HP Mustang Salleen, and lets not forget about Johnny Pag’s fleet of Ferrari’s, but he only drives one at a time. So this puts my race group at a total 9 cars.

On the track at the same time for this particular race event are the NASA “AI” (American Iron) series and the “CMC” (Camaro-Mustang Challenge) see www.americanironracing.com . These are fully race prepped, slick tires, 350 to 400 HP good ol American racecars. These two race groups include about 28 additional racecars on the track at the same time. This put the total field of cars racing at 37.

Race Day

We woke up to a cold, foggy, and drizzling morning. We got to the track and prepared for a warm up session before qualifying later in the morning. Because the track was wet and foggy we took 6 laps behind a pace car. It was kind of a waste of time but you new your car running.

Qualifying

It was 11 AM and time for qualifying. Because there’s so many different race groups running the track the same day your entire race group qualifies on the track at the same time. You get 20 minutes of track time to do your fastest lap, and that includes passing slower cars in the process. I did crappy in the “Super Unlimited” class running a 2:01 which put me 9th and last in my starting position and I think 14th overall with all the other cars on the track.

Race

After a drivers meeting where we discussed good sportsmanship (no dive bombing or spinning your competitors out), we prepared for our race. It was 3 PM and cloudy so track temperatures were ideal for our engines but less then perfect for our tires. I strapped in my car with my Hans devise, seatbelts drawn tight enough it’s hard to take a real deep breath, window net up, motor running and showing good oil pressure, EGTs, and solid boost pressure. I drove to pre-grid where we set up in our starting order for the race. This particular day we were having 2 rolling starts. The “Super Unlimited” group would go first then the “AI” and “CMC” would keep about a hundred feet behind us and start second with two separate green flags.

We pulled onto the track behind the pace car with its lights flashing blue, at about a fifty mile an hour pace. We scrubbed our tires to get built up tiny bits of melted rubbing off, then speeding up and braking hard to get some heat in the tires. We did a full lap behind the pace car through the road course coming up to the front straight on the oval. The pace car pulled off and we tightened up our nine-car group waiting for the green flag to be dropped.

A flash of green (I was in 3rd gear) and we were off. The field of cars began to spread out with the Rolex Porsches taking an instant lead. I passed the fiberglass bodied 911 (also yellow in color) and turn 3 onto the road course came up real quick. From that point it was a blur of concentration. The constant shifting, braking, turning, accelerating, checking your mirrors, checking your gauges, oh yeah, looking where you’re going all seems so mind-boggling. How cool is that?

The races are timed sprint racing. That means its balls out for 45 minutes straight. Your car screws up, you blow a tire, you spin out, you lose. The only way you become a descent driver is seat time. Practice, practice, and more practice. But what a great way to learn!

Back to the race: I got passed by two really loud 400HP Mustangs. I know the drivers in both cars are racing school instructors. I’m not making any excuses but the last time I drove my racecar was four months ago and my daily driver is a Dodge Ram V10 2500, 6600lb. truck. Anyway, it’s about the middle of the race and I’m learning how to use my new Stop Techs. I can now brake at 25 feet before a turn where it used to be 50 feet. I’ve got that yellow 911 Porsche on my ass the whole time. It was lap 10 and I doing about 110 MPH on the small back straight coming up to the S’s before the oval when I lock up my brakes and flat spot my front right tire. I kept it under control but now my front wheel is bumping like a sewing machine.

I get out on the front straight of the oval and accelerate to about 140 MPH and I fell the car lifting off the track so I begin to feather the pedal. I’m able to keep the Porsche behind me and I’m still on low boost. I got onto the road course and continued to push as hard as I could. There’s nothing better then a little adversity to make you want to go faster, even with a flat spotted tire. All of a sudden the two “Rolex” Porsches lapped me but I see I’m coming up on the Ferrari. I make it to the oval and pass the Ferrari with that dam yellow 911 still behind. It’s 140 MPH again and the car starts to lift and I feather keeping my ground. Another couple of laps go by and I’ve lapped at least a half dozen Mustangs and Camaros when I see the white flag come out.

 

I’m not ashamed to say I was tired and beat up but I kept that yellow 911 at bay. It’s the last lap and I’m on the back straight of the oval going from 140 MPH down to 40 MPH when a Mustangs spins out right in front of me. He doesn’t make the turn and goes off the track and I lock up my new brakes and do a half spin on the track. The yellow Porsche goes by with two Mustangs behind him. I put it in first and do my DSM drag car impersonation and end up passing the Mustangs and get that dam yellow Porsche in my sights. The 911 made it through the S’s before the oval and I’m probably 75 feet behind. I hit boost 2 (like turning on a super charger) and was only 10 feet behind him at the checkered flag.

 

Oh man!!! It was a great race and I was friggen exhausted. But it’s the best kind of tired I could ever feel. We all pulled into the paddock area and parked out cars behind each other, got out, shook hands, and recapped the whole race with each other. They gave out trophies, took pictures with drivers and trophy girls, and we put our cars in our garages to get ready to do the whole thing over the next day. I’m hoping that’s what it’ll be like in heaven.

Results

Saturdays race I placed 6th in class ahead of the Ferrari, Corvette Z06, and the Salleen DNF’d. I took 10th overall with 37 cars running and was doing 1:56 laps. This will all be official when the AMB transponder results are posted on the NASA site.

Sunday race and results

Sundays race was cloudier and colder. With fresh Hoosiers on the front, the car ran great and I felt a bit more confident. I didn’t flat spot any tires and I beat that dam yellow 911 Porsche that hounded me the day before. The Salleen and Rolex series Porsches took one, two, and three. I placed 5th and I think 8th or 9th overall and I think my lap times dropped a second or two. Not bad for a 2.0 liter four cylinder engine against a bunch of V8’s and factory built European racecars.

Carnage

I flat spotted 3 new 275/40-17 Hoosiers down to the cords. Cracked my front splitter in half and tore up my front valance a bit. All easily repairable for the next race at Button Willow Race Park near Bakersfield Ca. on April 9-10. Oh yeah, the tube framed $250,000.00, 2300lb., 750 HP, Corvette Z06, blew up his engine and is looking at $50K to $75K rebuild.
I love my DSM…

Road/Race Engineering’s EVO 8 Weights

We weighed our shop car back when it was stock. Had about a half tank of gas in it. Regular options including the Biggee wing and a sunroof. Weights are without a driver.

Here is a new stock EVO 8 RS we just weighed (5/04) Full tank of gas. The RS comes stock with no stereo, no sunroof, very little sound deadening, no ABS, manual windows, but they do have A/C.

Those HID lights are cute and sure look nice at night. But that is close to 17 pounds you are carrying around hung out on the worst part of the car to affect handling.

 

EVO is SCC Magazine Car of the Year!

MMSA had a  ceremony to mark the receipt of the Sport Compact Car magazine Car of the Year at the Cypress headquarters this last week. RRE was invited to bring our shop EVO race car along with a bunch of guys from www.socalevo.net. Basically anyone that could get the day off from work came out.

SCC Mag Editor Scott Oldham presented the award.

The RRE EVO 8 posing all hard with the award:

All the owners got to line up for publicity shots:

The Mitsu top brass were impressed with how many owners turned out at late notice on a work day. THey promised to do a better owners appreciation day later in the summer.

They even made us EVO and 3 diamond shaped cookies :-)

 

 

How to Rate Coil Springs Without a Spring Rater Tool

Mathematical Spring Rating Formula

Not many people have access to a spring rating tool. You can come a lot closer than you would think just using some dial calipers and a measuring tape to measure the spring rate of your springs. Here is how to do it:

SPRING RATE = GD4/8NM3

G  = Torsional Modulus for Steel     11.25 x 106
D = Wire Diameter in Inches
N = Number of Active Coils
M = Mean Coil Diameter in Inches. Mean Diameter Is:

If using I.D. = 1 Wire plus Inside Diameter
If using O.D. = 1 Wire minus Outside Diameter

8   = A Constant for all Coil Springs

The “G” Factor is always the same for all coil springs made from
steel  (11.25 x 106 can also be written as 11,250,000).

EXAMPLE: 10 active Coils and a mean coil diameter of 5.00 inches and a wire size of .625

11,250,000 x .625 x .625 x .625 x .625       =    171,661,370
8 x 10 x 5.0 x 5.0 x 5.0                                                 10,000

(Constant) x (Active Coils)  x  (Mean Dia.) x (Mean Dia.) x (Mean Dia.)

Spring Rate    =  171,661,370 / 10,000

Spring Rate    =  171.66 lbs./per inch

HOW TO DETERMINE ACTIVE COILS OF A COIL SPRING:

Count total number of coils, subtract a coil for each coil that touches, these are dead coils. Ground flat ends are a dead coil.  Start count with cut-off end facing you directly above would be one and so on. Not all coil rings are even coiled. You can have .125, .25, .5 or .75 of a coil (Example 10.25 Coils).

 

Sport Compact Car Magazine – The Ultimate Streetcar Challenge 2003 : The Guru Panel

Reprinted with permission from Sport Compact Car, June 2003

While we were out in the sun having fun, making dyno pulls, taking Grandma for a ride, our panel of engineering gurus was locked in HKS’s shop, picking nits.
From the June, 2003 issue of Sport Compact car Magazine
By Dave Coleman
Photography by SCC Staff

Our assembled panel of automotive know-it-alls consisted of three aftermarket powerhouses: John Concialdi of AEM, Oscar Jackson of Jackson Racing, and Mike Welch of Road Race Engineering; and two engineers: Dan Ehrlich of The Aerospace Company, and Mike Kent of Bell-Everman, Inc.

The incessant buzz of a defective overhead light, which rang through their heads the entire day, would have driven any sane person mad, but engineers have an almost inhuman endurance in the face of tedium and monotony. Anyone else would have taken out their frustration on the last few cars with crushing scores and harsh criticism. The last car that passed by our panel actually won.

Judging was focused on six areas of the car, each with a different number of points available, reflecting that area’s importance for performance. The engine was worth 40 points, the drivetrain 15, the suspension 20, bodywork was worth only 5, and brakes and interior modifications were worth 10 points each. The judges focused on modifications, looking for logical changes focused on improving performance. The fact that the Laminar Viking was built from scratch, essentially making it one giant modification, was surely crucial in overcoming the judges’ days’-end grogginess.

The Laminar’s turbocharged rotary wowed the judges, as did the Penske shocks and, of course, the featherweight tube frame clothed in carbon fiber. The judges were disappointed only with the rotary’s oil leaks and the exposed terminals on the fuel pump, which they deemed far too likely to start a fire should the Viking be rear-ended. But really, who can argue with 1,700 pounds and 360 hp? Mike Welch’s evaluation was, as usual, straight to the point. “He built the whole damn car from scratch and did it well. He wins.”

Paul Mumford’s Viper was only three points behind the custom-built featherweight. Credit the fact that it was built for the track by people who really know what that means. Penske shocks are a sure way to get the full 20 suspension points, and the Caldwell engine is a no-brainer for a high engine score, but it was the details that really impressed our weary judges. Details like carbon-fiber brake ducts, small air deflectors ahead of the front wheels, and the fact that the cold air duct in the hood was blocked off because the stock duct doesn’t actually work at speed. The wear and tear of countless track days, like the massive StopTech brakes that had clearly been cooked, also gave our panel a tantalizing glimpse of the outside world they’d been longing for all day.

 

Looking farther down on the finishing order tells you just how picky our judges can be. Deric Massie’s 384-hp Integra Type R was tagged by several judges for the fuel pump wiring. Too small a wire gauge, they said. Poor installation of the bolt-in roll bar and harnesses also drew the wrath of the geeks, leaving the Type R with a negative interior score from several judges. In fact, the Type R’s interior was deemed unsafe for our track tests, so the generous folk at Sparco stepped up and gave Massie new seats and belts so he could continue with the competition. The Type R’s engine, however, scored well. John Concialdi was especially fond of the AEM cam gears and fuel rail.

The Skyline’s eighth place finish seems odd, until you realize the car was mostly stock.

As good as a stock Skyline is, the judges were looking for modifications.

Mitsubishi Commercial Shoot @ RRE

MMSA asked us to sponsor a So Cal EVO and Eclipse club meet here at the shop. On a Saturday we blocked off the cul-de-sac and had pretty large gathering.  They shot real film, got some cool group shots and working on some cars. The above commercial is what came of it. You can also see what they shot @ Irwindale’s 1/8 mile drag strip at night.

 

Araknyd – One Clean Spyder

This is one of my all time favorite 2G Eclipses. Mark (Araknyd) has this crazy attention for detail and style that shows through out his 1997 Spyder GS-T. Sure it looks like a show car but it gets used as a race car too. Mark regularly drag races (1/4 mi.: 12.634 sec @ 108.52 mph, 1.84 sec 60′) and autocrosses his Spyder. Enjoy the pics!

RRE Turbo Oil Supply Line Instructions

Install the banjo bolt fitting onto the end of the -4 stainless line and tighten the fitting before bolting the banjo fitting to the turbo. Install the assembled oil supply line to the turbo before installing theturbo onto the manifold. Use new copper crush washers and torque the banjo bolt to about 25 foot pounds.1G: Remove the correct Allen plug from the oil filter housing. See the photos below for the correct location !If the Allen plug is tight and you think that you might strip out the Allen socket, heat will loosen it. The heat allows the aluminum housing to expand and loosen it’s grip on the plug. Heat also loosens any thread sealant. Get it warm with a propane torch or oxy/acetylene torch. Don’t melt anything, just warm it up good. If you strip out the Allen fitting to the point that an Allen wrench wont turn it, you are screwed.2G: Remove the larger fitting and replace it with the 90 degree fitting.Use thread sealant or Teflon tape on the pipe threads that screw into the housing. Note that the threads are cut into the housing at a different angle than the face of the housing. It will almost look like it is threading into the housing crooked. Be careful with any sealant or tape, you do not want anything to get into the turbo bearings.If you find that the clearance to the oil pressure sensor is too close to the fitting to screw it in, remove the sensor, install the 90 degree fitting and re-install the sensor.

Oil supply location on a 2G

Note that the fitting screws into the housing hole at a slight angle to the machined face. This can seem a little odd when first getting the threads started. Note the angle of the stock adapter fitting before you  remove it, this will help. The fitting threads are a tapered pipe thread, as you screw it in, it will get tighter. Be sure to stop at a clocking that will allow the proper run of the oil line.

Tied off to the fan shroud.

Tied off to the fan shroud.

Don’t let the line contact the fan shroud directly. We use a double zip tie to separate them.

1G

If you specified the oil supply line for a 1G, use the supplied short 10mmx1.25 bolt and crush washer to block off the stockoil supply location at the cylinder head.                                                                                     Oil supply location on a 91-94 1G Turbo

91-94 1G supply location pictured. You want the upper and outer fitting location. Using the lower fitting on a ’91-94 oil filter housing (water cooled oil cooler) will result in the turbo receiving unfiltered oil.

90 1G supply location pictured.                                                                                                                                 On a 90 model oil filter housing, the two fittings are spread out a little more. Use the lower fitting on a ’90 oil filter housing (cars with a factory air cooled oil cooler). Using the upper outer fitting will give unfiltered oil to the turbo.

Stock, the turbo oil supply is just about the last oil in the whole motor. If you get it at the oil filter housing, you get oil fresh out of the filter.                                                                                                                                    Note that if you do not use the specified location, you will be using unfiltered oil.
