Aerodynamics & Diverting Wind Resistance ?

I agree fully, but in my particular project I look for "little things" that may add up - even a tenth.
Please track your times and modifications. I know you’ll post honest data, you always do. It will be interesting to see your results. I would be willing to bet on a 100 mph 1/4 mile truck, there is zero aero modifications you could make that will gain you a tenth. All else remaining the same. I got to be a part of a bonneville team (I designed the nitrous system and had no hand at building the car) and was privy to data from aero testing done by a major auto manufacturer. Very interesting to see how manipulation of the air around and under the body effected speed. It took a lot of air speed for some of their changes to do anything at all.
