Could I put a relay switch on the VSS so that when the driveshaft speed gets too fast, it cuts all power to the motor? Would that work, even though the driveshaft will definitely go faster than 1320 RPM...
I dunno where I can find a 10 HP electric that has dual shaft and revs to like 3-4k or more?
I know that rear discs drag a bit more, but there are fixes for that, like return springs, etc, which allow them to open up just further than they normally would, without really affecting pedal travel.
Thanks for the tips and all so far guys! Keep it coming!

The RPM limitation I'm talking about is where the motor comes apart because it's not balanced to higher RPMs. For an Advanced DC motor I think this starts fairly north of 5,000 RPM. (You can also band the comm to increase this.)
I imagine that most forklift motors would do okay in this space. MetroMPG, do you remember what Jim said your motor would take, RPM-wise? I think all of the Advanced DC motors are also at least 5K. You could probably take a few minutes with one of the online RPM calculators to figure out what the maximum driveshaft RPM is, given the gear ratios and engine max RPM.
If you find an article on how to DIY return springs, I'd be interested, as the Clunker has rear discs.
