RE: A grand opening in the Diffy-q's

```i appreciate your civility (lets keep it that way), but really (once again)
you don't understand the simple mechanics of a diff.  until you do, the fog
will remain.  perhaps you are misunderstanding what torque is????  you need
to think through your scenario once again.  what is "torque" without
tractive force?

once again, an open diff transmits equal torque.  by definition.  a locked
diff (no speed difference) does not.

to your example, with centre locked and wheel lifted, all torque will move
to where the tractive force is, in this case to the rear.  100% of it.
every time.  with the centre unlocked and wheel lift, the torque in the
system *must* be equalised (because open diffs do that), and the torque will
go to the spinning wheel (same torque across all open diffs, different shaft
velocities).

i'm happy to refer you to some reading if you'd like to understand this
fundamental.  up to you.

I'll try my darndest to keep this one civil, but really appreciate the
opening Dave.

Ok, let's take your "understanding" to the next step.  Let's take a hot
corner on the track, *diffs locked* in my Gen 1 urq.  Lifting the left front
inside wheel.  How much of the torque is shifted to that wheel dave?  Let's
*diff unlock*, run open center differential in the same turn, lifting the
left front inside wheel, how much torque is shifted to that wheel?  Given
your "understanding" above, why would the gen 1 rally cars run center diffs
locked?  More understeer:)?  Maybe it would be simpler if you compared a rwd
open diff to a detroit locker, then work the front to rear on a quattro.

Geez Dave, I think I understand, but that buzzing sound....  Yikes!   In
deference to "opposite day", I'll just give you the opportunity to correct
yourself, then we can move on.
