I thought that larger tires would increase the speed as well, but with field weakening both on and off, the speed was the same with it on/off w/145r12 tires. Probably the 3.5 motor is just at the end of its capability, and wind drag, etc. combine to defeat it going any faster than 36.

The tires are run at 40 psi, mostly because I can't stand the road noise and bumpiness - even at 42 psi it gets bad. I may try 60 psi for a test to see how much of a difference it makes. If it'll do 45 mph at 45 psi, I may just learn to tolerate a bit more noise. 8-/

I did a cd calculation, and the Citicar ended up being around .68 if memory serves. Not quite a brick, but close... If I can figure out a way to mount a temporary support structure to the body without making holes in the plastic, I may try a boat tail and see what change happens.

I should be at the c-car meeting in mid-May as well - see you there...
