AWD Turbo Parts and Performance

Heat Protection

Back over the last month we have been tweaking on Ben’s new track car. Remember the pretty red EVO RS on the cover of DSport? That one. With the big manly Borg-Warner EFR Series turbo and loopty-loo manifold hanging out there baking everything for 30 minutes at a time on the road course, some protection from all that heat was in order.

How things looked a month ago:

Ben started with moving the radiator hose away from the manifold. Then we connected the water cooling ports to the twin Tial wastegates to keep the diaphragms cool. We had to re-configure the water pipe and thermostat housing to try to keep the hose routing clean and tee fittings under control. The boost and coolant hoses had to be heat sleeved.

My favorite part is the heat shield that Lod came up with to get the manifold heat up and out of the engine compartment. It is a simple bolt on piece of sheetmetal with some reflective insulation on it. It directs the heat up and out the hood vent before it can bake anything else under the hood. This chopped pic shows it in relation to the hood vent.

The car is getting prepped for Superlap Battle November 8-9 @ Buttonwillow Raceway.
