Sub-100 degree air under full boost? It gets hotter than that OUTSIDE here during the summer!
I wish my IAT's were that cold. Guess I need to get off my ass and design an intercooler. I usually see 135-145F under full boost even with the water injection...which leads me to my next question. What core size did you use for your intercooler? I'm just doing the preliminary measurements, design, and information gathering right now.
