Heck yes you can over-volt your motor!

My motor is a weenie 24v 60 pounder! I'm running it at 72 volts with no problems. I didn't advance the brushes or anything. If you have a 48v motor, feel completely secure in the fact that you can run it at 72 volts. 72v should get you up to like 45 mph I think. I don't think freeway speeds are practical at 72v. The current draw to be way too high. Well, maybe if your car is really aerodynamic. I have a ghetto super beetle, about as aerodynamic as a yeller monkeyturd (an un-aerodynamic one). At 72 volts, it's top speed is about 45 mph, but 35 is more practical to keep current down.
