drilling a hole in the back of your scoop?

I would think doing that will allow the air to just pass over more instead of directing the air flow to the carb, but it is just a 5/8" hole so it's not that large of a hole. Is your carb sealed to the hood? You see people mostly on import do holes I the rear bumper to decrease drag. Be interesting to see the ones that do the hole drilling if it does show benefit
