[QUOTE="fishpick, post: 15612169, member: 182347"] While I'm not a Cobra / GT500 owner - I can tell you I have been fighting high IAT's with my SC setup (like 50*+ over ambient) and it's NOT the HE or the IC efficiency - for me it's really JUST the underhood heat being consumed by the intake and fed to the engine - if I "get on it" so I'm really sucking in the underhood air - where I'm generating boost (which makes heat) - I actually see my temps go DOWN because the external air is cooler than than the under hood air and I have gulped all the "heated" air down. This seriously sounds silly - but I have found my IAT's in general are "lower" over all - the harder I drive the car - because I move more air under the hood by virtue of the car "eating" it and keeping fresh air coming in... All things equal with ambient and engine temps - the IAT's will be 50* high when "around town" and like 35-40* over ambient at highway speeds... and drop to 20-30 if I'm jammin on the accelerator and managing the gears so I'm seeing boost on the gauge and KNOW I'm pulling a ton of air in. I'm adding some fans to the H/E and opening up the grill a bit more this weekend... but it's possible you are seeing the same things I'm seeing. [/QUOTE]
