Default thermal control for SC owners

Again, kudos to xviper for his excellent work. Let me say upfront that my efforts here are aimed at mitigating the effects of heat on this car, not to increase baseline performance.

Unfortunately, with the SC, the under-the-hood scene changes significanty. Plus, there is the added issue of the SC compressor adding it's own heat, but this needs to be solved with an intercooler (actually, it would be an aftercooler - I've learned something from all that web surfing!).

So far, I have cut out the faux air duct on the airbox side (now it's a real air duct) to allow fresh air to enter that side and I have insulated the rear of the airbox and the side that is facing the SC compressor. The back side of the air box looks directly at the exhaust headers; feel the back of the airbox after driving around for a while - it gets pretty warm. I have also partially insulated the hose that carries air from the airbox to the SC compressor (partially, because I ran out of that EXPENSIVE, SMALL piece of ThermoTec that I bought for the job).

The next thing I want to do is somehow insulate/isolate the airflow from the front that flows by the radiator.

Unfortunately, I haven't had the chance to check out how the airbox insulation works. Also, it has been uncharacteristically cool around here with low humidity, so I'm not sure I'll be able to tell a difference in performance (if any) until it gets back to good 'ole summer weather.

As for the new air duct, it did seem like the car recovered quicker from a heat soak (sitting at a long light) than it normally does once I got moving again.

PLEASE - any other thoughts out there?
