My brother rode along and took time for me. He started the timer @ 55 mph and would say 8...9...10. At the 10 I would call out my speed and he would record it.
I definitely think a full boat tail will help. 0.269 Cd is still not considered low drag to me, even with my numbers approaching Prius territory. I want <.20 Cd and I am discussing with Aerohead about getting the ZX2 to 0.15.
A lot of my work has been quick and sloppy, honestly. I want to go back and refine all I can with better materials and with greater precision. My rear belly pan does not have the correct angle for the lowest drag and I need a middle section pan.
My biggest gains are going to come from the engine and transmission. The ZX2 is too deeply geared IMO to maximize the potential of a low Cd. The load on the motor will have to increase in order to reach a maximum BSFC, and I have three ideas regarding how to get there: Higher gears, lean burn w/ turbocharging and having an late intake opening (think Atkinson cycle).
