if its a race car, go with air/water. if its a street car, go with air/air. even tho a a/w setup as a heat exchanger, its not enough to keep the water cool after a long drive. but if its a track car, you can fill the tank with ice when you get to the track and have freezing water running though the intercooler.

as far as meth goes, its a great way to cool the air as well as add fuel and add octane. i ran a meth kit back when i was supercharged and picked up 50rwhp after i retuned for it. i plan to run a meth kit on this motor as well. i expect to put down 600rwhp+ as it sits and would like to see another 75 when the meth is spraying
