The pressure just back from the leading edge of the hood should be close to ambient, and fairly easy to overcome with the RAM air from the front, but the area in front of the windshield is a very high pressure area and not so easy to overcome.

IMHO, only if that huge reverse scoop is moving that high pressure area in front of it instead of the windshield and actually producing fairly smooth flow up and over the windshield/roof would you have a lower pressure zone behind the scoop. You still have all the pressure from the air hitting the remainder of the windshield wanting to escape into that low pressure area if it exists to overcome as well before you actualy get vacuum from inside the engine bay.

Oh No, I think JC and I may be agreeing again.. :shock:
