I was just sitting in a very boring training class here at work, and my
mind started wondering.  I was thinking about the 292ci motor and how
its longer stroke helps increase the torque at lower RPMs.

I was just wondering if this would apply to differentials as well.

Think of it this way...  if you had two different theoretical axles,
equal in every single way except for the diameter of the ring gear,
would there be more or less leverage (torque) applied to the axle
shafts with a larger ring gear vs. a smaller one? (10.5" and a 8.5"
gear respectively, but with the same ratio)

I was just thinking that the outer edge of the larger gear would have
to be traveling faster than the smaller gear in order to make a
complete revolution in the same period of time...but would there be any
loss or gain because of the different diameter ring gears?

Again, this is assuming all other things being equal, where weight and
ground clearance and tire size are of no relavance, and the tests were
conducted on a rear-wheel Dyno setup.

Forgive me if this is completely asinine.  I'm just *really* bored
today ;-)
