Crankcase breather question

I can add to the question of the scoop adding pressure to your intake systems.
It totally depends on your hood shape and scoop height, but I can tell you most cars actually have a vacuum in the scoop when at speed.
A scoop would have to be higher than the smoke stream shown on these cars in a wind tunnel.

Exactly. Most scoops don't work because they are way too low and too far forward.

The more the front end is vertical, the higher it needs to be. The air hits the front end and almost goes straight up.
