drilling a hole in the back of your scoop?

I'm fairly sure it would make the car .0000000000001 faster.
Same with cutting the stupid holes in the bumper.

Just makes it where they lost by .000000000001 less. :D

Besides, what car pulling 600+cfm of air is going to leave anything stagnant?
It only matters at WOT throttle and if there is anything in the intake system stagnant at WOT you're driving a Prius.
