Mr Helmholz - simple model

> Gary what's a CVT...?

Constantly Variable Transmission, whereas the engine maintains an RPM
in its optimal torque curve, and the transmission, via a belt of some
sort, adjusts the axle speed.  This is typically done with two
interlaced pulley halves that mate together.  The closer the pulley
halves are together, the larger diameter the pulley is.  The reverse
would also be true, whereas the pulley halves pulling apart would
yield a smaller pulley diameter.  Works great in go-karts, and been
used for years.  Some of the carm manufacturers have been making units
for electric powered cars, and nowadays even small gas engine powered
cars.

Problem has been (to date) belt tearing under high power applications.

Our funny car has *no* gears.  Engine, flywheel, clutch, giant
lubricated spherical bearing, driveshaft.

We worship our SFI rated bellhousing :)
