as far as drag reduction the math is pretty simple.
For example:
Lets say frontal of 34
Cd of 0.45
Cda of 15.3
after modding, frontal of 37.5
dividing 37.5 into 15.3, we'd need to reduce the Cd below 0.408 to break even.
If it is well done, and then extended into a super smooth short boat tail transition, I think the Cd would be much lower than that. I see money!
Frank, I understand your concerns. Consider this though:
This top will allow for some optimized radii along the sides that will Improve
crosswind performance!
