RE: Hot turning in a quattro - T*rsen content warning

["Dave Eaton" <Dave.Eaton@clear.net.nz>]

the questions were simply to see what you understood at a basic level.  it
is one thing to observe, and another to understand.  and to help any other
poor sods still attempting to get information from this thread.  bear with
me.  some more questions.

1) what is the difference between a locked centre and a torsen in your
scenario if the torsen is not at the bias ratio?

2) as above, but with an open centre?

3) what do you mean by the comment "Any speed axle difference would result
in a front to rear alternate spin, it's in the presentation".  if there is
no axle speed difference during a normal turn with the torsen, how does the
torsen handle front/rear slip?

btw, some things you should understand....

1) a spinning tyre does not make the torsen shift torque.  torque is
shifting well before that point by definition.

2) a spinning tyre continues to support torque (i.e. supplies tractive
force).

>1) is the torque bias ratio exceeded in any of these
hypotheticalmanoeuvres?

Make the claim, don't ask the question.  In the "less than" wot I'd say no.
In the WOT you just might, but remember, a tire that starts spinning, makes
the torsen shift torque.  I would venture to say, it can't happen with only
steering input.  However, one interesting thing about torsens, watch them
sometime in a turn (or on a straight line accel) on the slick, you get wheel
spin AND torque transfer.  Remember, a torsen is dumb.  If you spin up both
the front and the rear tires at the same time, the torsen doesn't know
either
is spinning, it just assumes the driveshafts are spinning the same speed.  A
second of this, and then it starts to hunt.

2) is there any axle speed difference front/rear?  if so where.
Any speed axle difference would result in a front to rear alternate spin,
it's in the presentation.

>also you need to run the same scenarios with a locked centre diff.
U-U-U-U, remember, same cf
