I wish they would have shown more around the wheels and the underside, since this was the worst area on this car.

I emailed the guy that built this car. No Cd figures were given in the video, so I asked him if he would provide that data for us ( I also asked if he had data on the stock ( as in unmodified ) 'stock' car in regards to its' Cd and lift figures.

The site hasn't been updated in a few years so we shall see if we get a response.

Cali98Civic : I'm parroting what I have read regarding those scoops. Supposedly, those scoops were a last minute solution when the tires began rubbing the fenders above 200 mph. The engineers had some scoops from a SuperBee and attached them to the tops of the fenders backwards to hide a large hole that they added above the wheel "to exit some of the trapped air in the wheelwell." The front end of the car was so planted to the ground at speed that it was reducing the clearance between the tires and the fender.

Why the scoops face backwards is a guess to me. I had read it was to relieve the high pressure air in the wheelwell . It could just be a last minute solution to covering an ugly hole in the fenders, but from what i have read, they had some aero function.

EDIT : I emailed the guy with the car and he has replied that the testing was only done for stability and that no data was given such as Cd or lift.
( How does one pay $ 2,000 an hour and not get info like this ? ) :-/
