I was thinking the same way as LabMonkey... take X amount of air and compress it into Y volume and the temp will go up Z degrees, regardless how you're doing the compression.

However, the exhaust running thru the turbo is in the 700 to 1000 degree range, which heats the hell out of the turbo itself... that's gotta account for a lot of the intake charge temp. My guess is that a lot of SC guys see temp caused dets because they're running a SC on a fairly high compression motor already. I

'd bet a SC on a WRX instead of a turbo wouldn't need an aftercooler, since the WRX motor's designed for boost and the associated higher temps.

Okay, that last part's just a crazy guess.
