traction is the limiting factor, not motor power. You can basically put
the motors into wheelhubs mounted on a composite frame, and dump juice
into them until they melt, which will be some 100 sec downstream. Plenty
of time to smoke anything.Of course, it doesn't roar, and spew smokage, so it won't happen.
