[Viturro]

''No higher pressure or lower pressure, only a lack of pressure caused by the vehicle body moving though the air.''
¿? That lack pressure just can be low pressure air, i mean there is air, and just can be low pressure, (if that were high pressure air the car should have no drag, should have a boost).
And we know that there is air, because if there were not it will be a vacuum pump, and if there is vacuum the car couldn't even move even with 4000hp
So there is low pressure air. (if I'm wrong let me know why, please).
I think that the Venturi effect only happens in tubes (or closed spaces).
Wasn't the N.A.S.A. the ones that say that the air planes didn't fly because of Venturi effect, they fly because the wings send the air below it?(short version).
