According to car test or one of those similar desktop programs when we plugged the numbers in for the car with estimated HP and Tq output plus taking into account lowering the car and changing the FD ratio it came out to be a theoretical top end of 178 mph. I don't remember if that was RPM or aero driven though. I'm actually thinking in another year or so to take it out to Bonneville and see if I can set a land speed record in it. The class I'm shooting for has a 170 mph unset record yet which would be pretty cool to set in a contour. I've got to look further into the onboard extinguisher requirements though because if it requires an onboard fire supression system it's pretty much out of the question.
