The hoodscoops definitely don't help the flop, thats for sure. The OEM hoods have no holes under the scoop for the air to pass through, so there is more resistance hence hood flop. Its a shame the way the engines are designed, ram air or cowl inducted air could help the motors out a lot.
what? are you just talkin about the carbon fiber version? my stock hood has a about 4" X 8" opening under my hood scoop.
