air trap

[rip]

I was wondering I've heard that a large amount of lift comes from some air being traped behind under the fenders. Is this true?

See I've seen guys that have louvered the back sides of fender to try and help, some drag guys have ever gone as far as drilling holes in the back of the fenders.

So I was thinking has anyone thought about making a vent back there? Some thing that wouldn't only free up that traped air but possible use vanes to direct air upwards creating a small amount of down force?

Some thing in which you would cut a patterned out hole and rivet in a assembly of fiberglass (carbon fiber) vents and aluminum vanes?


thanks
