Here's what I said about it on the previous page... basically Torsen becomes an open diff if a wheel is lifted. Clutch pack types will not have this problem.

As long as you have some traction on the wheel that is slipping it will transfer some percentage of the torque to the opposite wheel, meaning when you are powering out of a turn the power will shift to the outside wheel. You can "fake" it by pulling up the ebrake, not so much to lock up the wheels but enough to give some resitance for the diff to push against. A mechanical locking diff will actually sense differences between the shaft speeds and apply a certain amount of lock to try and equalize them, so it will still work if one wheel is lifted.

STI has a clutch type diff in the center and viscous in the front and rear (AP Suretrac on the front in some years). E-diffs are different, they apply the brakes to move torque around.
