Dave,

Missed this one.

Not trying to beat you, just enjoying the process.

If this were true then why don't most racing sanctioning bodies use TQ/weight.

Instead they use HP/weight or more specifically -- lbs / HP.

Check out PCA.org's club racing rules. They go to great effort to class different Porsche years and car types together in classes based solely on lbs/HP.

Not sure about the following but here goes in the sake of learning:

Thus something like -- Car Weight/((Torque x RPM)/5220)) = Acceleration Potential.

The 5220 number is just an arbitrary factor to determine the size of the Horse to be used by all.

Thus-- Car Weight / TQ x RPM = Acceleration potential.

Thus -- Car Weight/Power = Acceleration Potential.

Math is not my strong point (sexy tutor with bad breath stalled me at algebra thought I tested gifted in it) so this may be a bit lame. Sorry if that is the case.

It is all good.
