The added traction off the line comes from the weight over the rear tires, not weight added by downforce of the wind, but purely from the weight of the gate.
Agreed. There is little to no difference when we tested the gate/no gate theory in the 1/8 mile, but as you speed up the difference is noticeable. Hence, the performance losses in the 1/4 mile.

ok ill say this again. I launch in 4WD so traction really isnt an issue. I will switch to better tires in the near future as well just for the hell of it.

My truck puts down alot of power you'd be surprized if I tell you that I break the tires loose in 3rd gear (4.10 rear end) when in 2WD, 750bhp here and going to at least 850 soon.

What im looking for is to reduce high-speed drag caused by having the tailgate, for maximum high-speed acceleration.
