I gave my though I passed along more than a few seconds on contemplation try 
the fan belt test.

Hi Dave:
I agree the length of the arm affects torque but me thinks it affects
distance traveled also. The two are interrelated. I was only using the top
Fuel tire to illustrate a point about squat or footprint. I also should have
said effective ratio and not gear ratio which is mechanically fixed.

The amount of belt squirming out in front and back (creating the contact
patch) is not adding to forward motion. For example you could have 12 inches
of foot print or 2 inches of footprint. They both eat up HP and
circumference but the shorter one gives more efficient forward travel. But
since we are talking about LSR tires with little or no squat I agree the
effect is negligible as well. Since I am moving I should not have started
this thread. Let's continue this at salt talks.  :-)    -Elon
