I have retired officially, but I choose to come out of retirement every now and then to beat our Deployment Commander, like just a little bit ago HAHA.

Evans is very "cool" stuff. Possibly flammable. I've seen sprint cars pop a coolant line and since Evans is polymer based. Let's just say it was an exciting show. You couldn't see the car for the flame job. I am planing on using Evans in my race car this next season.

If temps from the turbo is your concern why don't you try a rearmount? By doing that you'll keep the engine and turbo heat separate making the engine easier to cool. Just my $.02

too much stuff going on underneath the car. Hillclimbs equate to bottoming out

Really, didn't realize that. Well good luck. Was just trying to help.

I would run a turbo with a larger turbine wheel and a/r. This will help keep EGTs under control with very long pulls. V mount with a vented hood sounds like a good idea. I'm not sure if its mentioned, but water injection would also be a good idea. If you are really worried about underhood temps, we offer a lot of stuff to combat that.

This LIM heat shield is very impressive! I wonder if it is 100% sealed? I have noticed that the very bottom portion of the LIM ALWAYS gets heat saturated even with certian heat shields.

255.00 is a bit steep BUT if it is 100% sealed it would be worth the heat restriction benefits.

thats rather shiny looking! Well see how the build comes together. Right now i have to finish the rally car before i get crazy on the other rx7. I might run pikes peak in 2011 in the rally car if im not co-driving for my friend. we shall see. thats over a year away so the hillclimb / road course car might be up and about.

Something that hasn't been mentioned is ceramic coating. I know that Swaintech has a black body coating for radiators, intercoolers, etc that increase the heat dissipation. It's also used on the cold side of turbos. You can also gain some benefits from insulating the exhaust manifold and hot side of the turbo along with the downpipe. Also look at including an oil to water heat exchanger. That way you tie your oil and coolant systems together and are able to increase the volume of your heatsink and increase the cooling area. If you wanted to go the extra mile you can coat the exterior of the engine housings to either dissipate or hold in heat. I don't remember which Swaintech recommends.

Heat-shields, properly designed air splitters, high water content coolant, you should take the time if its run especially hard to "fin" the oil pan and anything else you can air cool. read the book MAX BOOST by Corky Bell for great advice on designing baffles for air flow. just minimize the effects of the heat you are creating so go for heat wrapping and shields on the exhaust and then maximize the amount of cooling you can achieve by all those other things ive said.

The very bottom is sealed.

I recently had a customer do one of our turbine housing heat shields ( his turbo kit has his turbine close to the lim) and he picked up 7rwhp on a back to back test... Not too shabby...
