my retarded friend insist that no one ever ices their intake at the track. Prove to this homo that hes wrong.
Michael Yount said:Tell your friend it's all about thermodynamics -- spell that word for him if you have to. For every 10F decreases in intake/combustion air temp, HP output increases by 1/2%-1%. Anything you can do to help lower the temp of the air/fuel entering the engine will help power production. That's why many boosted cars run intercoolers - to get rid of the heat that compressing the intake air adds. There's a reason you see people pushing cars through the staging lines with ice everywhere. That's why, all other things being equal, cars run quicker in the spring and the fall than they do during the heat of the summer. That's also why hanging a big conical filter under the hood where it picks up hot under-hood air probably makes less HP than the stock air filter box.

Definatley not the norm though...I'm sure I changed my shift points or something else on that run.
I havent done it since for 2 reasons.
First off, it's messy as hell. All that Ice melts and water drips friggen everywhere.
Secondly, I dont Ice my intake on the streets if I were to have a "friendly" encounter. It's the same reason I dont run a short belt at the track. Sure it will improve your times, but it doesnt realistically show what your car is capable of on a day to day basis.
One of the few good times that I can see to use it is when your hovering right at 14.00 or 13.00 and need that extra spunk to break into that new range you've been looking for
