cai or ram air, its running thru the compressor which gets hot and gets compressed which gets hot yet again. the fmic will play the larger role in keeping the air cool w/ turbo cars. i don't think the cai / ram air will make much of a difference in the car.
i could see the argument on a n/a car.
the problem is quantity...
your compressing hotter air which is less dense, and contains less oxygen and make it even hotter... even though your cooling it down with a FMIC and getting it cooler, you still are getting LESS air into the engine as warmerr air takes more space then cooler air, thus, making some sort of "bottleneck" as you won't be getting in as much as it takes more space...
what i mean is it's far better off cooling down ambient tempertarure air thats been ccompressed than trying to cool down hot air from under the hood..
i did alot of testing (with an industrial sensor i borrowed from work ( cost about 800$ CDN and is VERY precise) on my previous car and some friends too
at 75 degrees F ( approx 25 degrees celsius) turns out that the majority of cars will suck in air from a cone filter under the hood ( i.e. short ram) at about 122 degrees F / 50 degrees celsius ! and it shows on performance..
another test we did was at 60 degrees F / 15 degrees Celsius.. turns out the car was ALOT better and the air in the intake was at a 70 degrees F / 20 degrees C. and performance was alot better. the bottle neck effect was less present as the air was denser and more was getting in by the 3 inch pipe/cone filter assembly
for some reason (which i think is the way the car needs to cool off more at higher temps) the car at lower temperature was reacting better and to a point, the air inside the hood was almost as cool as the outside air..
like below or clost to freezing point, it "might" be ok to put a short ram..
