Ripped no disrespect taken. I love discussions like this. everyone learns a lot by looking at a question in many different ways. As far as the bubble goes maybe I exagerated a little

. I would bet though at 150+ their would be a low pressure bubble from the nose to the top of the roof. I can see maybe a ram air ket like the c4s at the plate in front of the car. But it would have to be totally sealed etc..
When I was talking about moving the air around the car, their def has to be some going to the rad. but the grunt of it is going around. I have had some classes with some Indy guys and thier goal is to create a vacum underneath the car. This keeps the thing planted on the pavement. by doing this they can keep the drag down, by not using as much downforce.
You are prob right about the smooth air right at the nose. It would be interesting to see Gm's testing docs in the wind tunnel.
But In general none of the after market air intakes will create any pressure. And If their was one which did, their would be no difference in track times. The amount of time spent at 150+mph and so many other varibles would be more important. I dont think anyone could even test it accurate enough. great chat .
