Lets first call the vast inside area of my outdated scoop attached below as the "Facility"
I'm just thinking of a poor mans super charger effect utilizing the scoop by creating a series of dams with various foils or spoilers inside the "facility" that will probably only work at speed. I have a few drawings that will take time to develop into actual dams that will then be temporarily affixed inside and do some testing Motown Missile style.
