aerohead -

I wonder if having the intake there helped any with keeping attached flow in the back? I can't really imagine the engine takes in that much air, but there might be something to the design with having the intake's vacuum only a small area above the exhaust's pressure to create a sort of bubble around the lower portion of the rear of the car that aids the flow by making a sort of "imaginary" boat tail extension?

It's a long shot, but I have to imagine that it's having some effect with such a low Cd on a high-downforce design.
