Re: Deference to differentials

<< Actually, you're both right on these two sentences.  The trouble is that
 PDQSHIP confused torque with power elsewhere in his message.  An open diff
 sends more *power* to the spinning wheel - that's torque * RPMs.  The wheel
 is spinning like crazy.  But the torque, as Dan pointed out, is still close
 to zilch, because there's no force to oppose.  The locked diff, by sending
 equal power to both wheels, ends up sending more torque to the wheel with
 traction.>>>>>
a lot of *torque* on it.  Is the right axle stressed?
Hardly... it's not doing anything.  So, at the output of the
locked diff, we see a large force (torque) on the left side,
and almost none on the right... hence, you could say that the
locked diff allows for different torques, or has split the
torque.
>>>>>>>
here we see that even though the center diff is locked, the torque split is 
not 50-50. if you wonder, "how often do i drive around on jackstands?" i 
would say pulling out of your driveway (snowy/icy) onto the road 
(salted/dry) would be nearly equivalent.

Sorry for my assumption of power and torque and traction, didn't read what
was argued, a self-imposed helmet whack on my shoei....  One might look at
these torque arguments on how it applies to the torsen center diff verses the
Gen I lockable diff, esp in low traction conditions on throttle (weight
transfer rear)....  Hmmmm, why would one want a torsen in the center vs a
50/50 lockable/open?
