So which is it? Do you now agree with me when I say that EDL on
the new Qs acts as two separate (front and rear) systems? You now
know that your previous assumption does NOT exist?

As I've said before, if your going to go that far, why not ditch the
torsen all together?

So you never want the rears going faster than the fronts, huh? Well,
before EDL can react, the rears must at least begin to spin a _little_
faster than the fronts. At that point, Tshift to the front has already
happened. EDL applies the rear brakes, thereby grabbing some of
that power to generate heat. No torque transfer, you say? In fact, I
can see torque oscillations as EDL slows, then releases (then slows
again, etc.) the rears through the turn.
It seems that you are trying to take the scientific high road with
your "physics" argument. Well, let's follow it through using the
scientific method. You have documented an event, and come up
with an hypothesis. In order for it to graduate to a theory, you
have to come up with a repeatable experiment so that the rest of
us can verify your results. How about a step-by-step recipe for
Others have tried to recreate the "bite" without success. You
shrug it off as a "non event." Not a very scientific response. I
have already suggested hooking up a laptop to the ABS sensors
to see what each wheel was actually doing during the "bite." Not
much interest in that one, I guess. It seems that you have lost a
bit of objectivity in response to the (frequently unjustified)
attacks of your findings. You ask people to argue the physics
with you. I argue that you have some homework left to do before
we can accept your hypothesis.
The simple formulae do indeed show that Tshift happens. No
argument there. Plugging in numbers to come up with values
for the shift is monkey-work. It demonstrates nothing more than
whether or not you have one of the flawed Pentiums. Proving
that Tshift is the source of your "bite" is the real issue here.
