.....As far as the Goodyear Polyglas, many of these cars are using an electronic traction-controlling device that's about the size of a pack of cigarettes and will fit in your shirt pocket.

I've been in and under these F.A.S.T. cars, and while these guys may spend cubic bucks on the engine internals, transmissions and rear ends, they don't even think that much about traction control. It's pretty much a matter of horsepower and torque way exceding what you might expect. No nitrous needed here. The tires pretty much are the limiting factor in this case.
