Well, in my finding of running air temp probes before and after the ic, I didn't really see much of a difference in temps between the b/p and the t/f. And to further throw things, I never seen a difference in air temps between a tmic and a fmic (while driving). Where the tmic gets into trouble is when you start getting into stop and go traffic. Which brings me to my next point. through all of my testing, the biggest factors that I have found is a larger scoop (sti), a good scoop to ic seal, and some kind of splitter that will send some of the sir to the front of the ic. This will not make the air temps any cooler, but what it does is lower the speed the car needs to be moving to see the air temps lower and make the cool down process happen quicker. With a good seal and a splitter with a sti scoop, I found at about 30 mph you can watch the post ic air temps start to drop (if the ic was heat soaked) and it usually only takes 1/2 to 3/4 mile for them to get almost down to ambient temps. Now, there are many things that I have found to effect this. Short ram intake=junk. You are sucking in the hot underhood air and it makes the cool down time HUGE. I will have to dig for some of my pics of my setup.
