Power to weight calc

[Dan Zorde]

Hmmm, so simple I never thought of just jacking up the back end to check.
Guess they will be checking that then.  Well it was worth a shot, guess I'll
have to think of something else to try and overlook during their checking.
Anyways, I had a play around with Bruce Bowlings road dyno program only to
get a very interesting answer.  By keeping everything the same (times,
gears, speed, etc) and only changing the diff ratio, the power figures
stayed exactly the same, only the rpm and torque figures changed.
