Ive seen the results.. We had a guy cut holes where you plan and drove around logging his results.. Then he fabbed in some duct work.. forcing all the air from the Ic thru only his rad..And it ran alot cooler!

he decided that the turbulance from the air going behind the IC affected the ability of both the rad and the IC. The diferant air pressures from differant entry points did not get along. The duct way allowed for more of a constant stream of air and was more effecient. He also said that the only orfice in the front of your car should be just 1 orfice for cooling and everthing else just caused drag.

I think your idea with the nostrols would work but you would have to do separate ducts for them. and dont bring outside air in behind the IC.. Keep it ducted directly to the Ic.

This guy who ran 11s in a 388hp saturn also said that with out a hole in the hood .. your IC wasnt working efficeiantly enough. Andthat was a bigger facter then frontal ducting.

Sorry bout the spelling .
