GE motor. what are it's limits?

[Royce Chow <rufus@infosite.com>]

I got some info off the motor I am going to be using in my opel, and I was
wondering what it's limits are. I am planning on painting the whole inside
of the endcap and the brush holders with high voltage insulating varnish,
and I am willing to adjust the brush timing if necessary. Here is the info
off the plate:

model: 58T1346B47
hp:   22.74
windings: series
voltage: 99.6
amps: 198
rpm: 2375
duty: 1 hour

The cal poly EV club's rx-7 is getting a transmission, and had borrowed it
because it had more low torque, and was better than the nearly identical GE
in a direct drive application. but now that the rx-7 is getting a trans,
they were going to return this motor to the guy they borrowed it from, so I
talked to him and ended up buying it from him :) so ANYWAYS, I know this
motor works good at 144v and 500A unmodified, and when it was used direct
drive in the mazda (lotsa amps), it barely got warm. So my question is, how
high in volts and amps can I go? I plan on having a cooling fan too by the
way :)  I only plan on doing 144v at foirst, but I want to know what my
upgrade options are :) (especially after reading about the mighty max :) )
Ok, at this point I'm just rambling...
