low top speed?!?!?!
 
I just built an MRX-3 that has a REX 321P in it. I broke the motor in, but I am still only getting 55 - 60 MPH out of it. Does anyone have any ideas of why it is not getting up to 75 or higher?

gearing, tire size, engine tuning, tuned pipe, track not big enough.

Good Luck with that, The fastest car at the Paris Memorial in October was 68mph done by certified radar gun.
