How do you direct ambient air through the intercooler fins? Looks like the air would not want to take this path without some serious convincing.

There is a low profile angled spoiler located at the back of the intercooler. It creates a positive pressure in the region directly under the intercooler, and that, coupled with the negative pressure in the bay, creates a very effective flow across the intercooler. We measured a 25-50F charge temperature drop under full boost, with 50+F occuring at vehicle speeds above about 30mph.
Surprisingly, none of the air pipes get even warm to the touch. Polished stainless reflects infrared extraordinarily well. In the begnning, we were planning to thermal-wrap various portions as needed, but it turned out to be absolutely unneeded.
