[V8] Making an A8 ride like a stock V8

[Buchholz, Steven]

... I think you might be able to get a bit of detail by perusing the
archives of the "Torsen" list on audifans:

Basically, what happens is that the Torsen tries to shift power away
from spinning wheels, which is what happens when the rear end starts to
come around.  The Torsen will start to drive torque toward the front
wheels, which can make the rears hook up and the fronts come loose.  I
find that I need to plan on backing out the steering correction for the
slide earlier than I would on my cars with the open center diffs to
prevent having the car go the other way.  This is the situation referred
to as the "spider bite" ... 

The one thing that is unfortunate about the center Torsen IMO is that in
any turn, the fact that the rear wheels describe a larger arc than the
fronts will cause the Torsen to bias toward the front wheels even when
there is no slip.  This same effect occurs on the rear Torsen ... the
fact that the outside wheel goes farther causes the Torsen to feed more
torque to the inside wheel.
