9 track tape drive motors - suitable for a go-kart?

This has only a little to do with classic computing, but it seems like it could generate epic amounts of email, so what the heck... Does anything know much about the construction and capacity of a typical 9 track tape drive motor? Like the big 1 foot x 6" tubes which I've seen a kennedy or DEC drive? I don't know anything about how they are constructed, but I assume they are high RPM and high torque. And probably some sort of DC stepper. I have a racing go-kart frame which is currently missing a motor (a CRG if anyone cares). It occurred to me that it might be fun to grab a large number of high capacity batteries and somehow rig one of the tape drive motors to the live axle. I assume via a reduction gear and chain. (clearly math needs to be done, but I want to start by finding the right motor) I would imagine several versions, starting with the simplest version but moving to something where both rear wheels are driven and having some sort of "software differential" and the moral equivalent of compression braking. no doubt there is something like alt.cars.electric-karts where I should go with this, but I thought i'd ask about the tape drive motors first. Anyone know what their specs are approximately and if they would be appropriate? (my goal is to be able to smoke the rear wheels and then turn on the traction control :-) clearly I've been spending too much time on the Tesla and Spacex web sites :-) -brad
