ram air is possible on cars...at like 180MPH. It requires the intake have only one opening, directly in the path of the wind (theres more to it though, dealing with high/low pressure zones). On a street car, Ram Air is more of a catch phrase than anything, its all just bringing more air into a somewhat restrictive original intake system.

 

i did the mod 2day and i have a questoion? by cutting a hole at the top of the radiator shroud doesnt this hinder the air to go through the radiator thus higher temps? bc on my old 94z b4 i knew anything i took off the plastic raditor shroud bc i thought it was just in the way and the car overheated fast bc no air was getting trapped in the radiator/shroud spot..wouldnt opening up this hole for the free ram air be the same somewhat?
