That is what STS says.... the long pipe and the air flowing over it will help cool it.
What I am seeing, the aircharge is raise about 18degrees every PSI of boost. I have 4 points to measure temp - outside air (in the grill), hat of the supercharger (post boost), IAT post intercooler, and then the engine temp.
even with my low boost the supercharger is often pegged that 255 degrees, with the outside temp in Texas 90-110 - wouldn't want that going ito my engine. The IAT usually runs only 20-30 degrees over the outside temp - so the intercooler seems to be working at 65%-75%....
