My new home fabricated ram air

Nice work.

From a physics standpoint, the "A body" scoop (I'm assuming the one in your sig), is actually one of the most effectively designed scoops ever offered on a production car. The boundry layer is accounted for and the holes are large enough.

The E body scoop doesn't account for the boundry layer (unless it's T/A scoop) and the openings are further back, somewhat lessening the "ram" effect.
