OK there are SOOOOO many reasons why it hasn't been done. lets take a look at the first year of the pontiac GTO it had hood scoops for ram air but they were not functional, any one know why???? it was cause pontiac didn't feel the GTO was gonna sell and they did not want to invest time and money for the wind tunnel test to make them work correctly. later year GTOs they did. why do you need wind tunnel tests you ask. well see if you place it in the wrong sopt you creat a vacume rather than an intake, which would be VERY BAD for perfromance.
