Trivia:
I know of a fellow who designed his own pring-loaded/oil-damped torsional
damper for his Sub, and he measured the twist in the spring using two optical
sensors (one before and one after the damper) and then calculated torque and
power. For him it was practically free, since he was using the damper anyway.

Survey & Specs
Guess I could calculate
torque based on calculated HP & rpm, but would that really add
anything? If I could think of a low cost way to measure it
directly, that would be a nice thing. Alas, cheap ways to do that
are hard to come by. Paul Lamar suggested an annular piston (to sense
pressure) behind the sun gear but I don't think that is either simple or
cheap. At least not for the guy that actually has to do it.
