what isn't true scott?  certainly you have previously stated that the locker
is a fixed torque splitting device.  it isn't of course, it is a torque
proportioning device.  you have never acknowledged your mistake.  are you
still saying that?

au contraire, it is entirely relevant.  both the locker and the torsen can
only use front/rear slip as inputs to their torque proportioning.  the
locker can't limit torque transfers, while the torsen can.  seems very
relevant to me.  mind you i can understand your assertion to the contrary,
given your position :-)

your wish to ignore the characteristics of the locker are rather
disingenuous.  the behaviour of the locker is entirely relevant.  i have
shown that the locker and the torsen use the same inputs to produce similar
results except that the torsen limits torque proportioning while the locker
can't.  i ave also shown that your bite scenario is just as easily made with
reference to the locker, rather tan the torsen.  if the bite doesn't happen
with the locker (and we've had at least 2 people on the list who claim that
it has), then we have a chassis argument.  which is phil's precise claim.

so, sorry, but the behaviour of the locker is entirely relevant to this
discussion.
