Wouldn't that be fun?

No, that's at "full field", with "only" 72v going in to the controller. The stronger the field, the more torque the motor puts out per amp, and the less RPM per volt. Since the controller limits motor amps to 500, this allows me to cram more amps in to the motor, producing more power.

I saw it sucking 300+ battery amps at one point (I was driving and couldn't watch it every second) in the middle of accelerating, so that's 25+ hp coming out of a "little" motor, and at a lower RPM than the original 3-cylidner would have been running to make that much power.

If/when I bump it up to 144v, squeezing more amps in to it will be easier, and I won't be limited to 35 km/hr at full field in second; I'll be able to take it all the way up to 50+. And third gear should let me take it up to 90+.
