Any race guys ever run a 3 or 4 inch hose mounted off the front air dam or attached near the outside mirror thru the rear fire wall and directed onto the fan? Does it add any cooling effect? Any pics of setups?

AJRS once told me that he finally solved heating problems that he had been chasing for years..
when he installed a roughly 6-8inch square duct. His came from a naca duct on the roof and then a clear lexa/plastic square duct through the cockpit and through the lexan rear window.. where it dumped onto a flat central electric style fan. (Think about the the roof ducting done on the porsche GT1, ralley cars, mcclaren, and other exotics) he runs all of his hot 4's without the metal front cooling shroud and without the front blower wheel, or front alternator. His installation of adequate cooling opened up all kinds of HP and longevity options for his -4's brant |
