I couldn't find anything the aerodynamic of racing link showing that having the spoiler up would increase mpg. It did mention drafting would cause the car in front to have less drag.

I was being sarcastic about the butt dyno
The problem is that to calculate MPG, you need to have constant conditions, speed, etc, so using a dyno actually would be a good way to get a good caculation
as far as less drag via drafting, again it comes down to aerodynamics and physics. Drafting produces a partial vacuum and effectively sucks the car behind in. Please someone correct me if I am wrong

Sorry, but the front vents are for cooling the brakes and radiators, they don't produce down-force. The front apron/lips generates down force, not the vents. I would guess the same is true for the Vette, cooling. I could be wrong, maybe someone can comment differently
