Any sort of friction-based LSD (including torque biasing types) require resistance torque from both drive wheels in order to prevent slip. As both the Torsen and the Quaife are torque biasing types, this applies to both. That means that if a wheel is clear in the air, they won't be able to do anything about it.

Its the lowest resistance torque that gets multiplied and transfered to the other wheel. If the lowest is zero, X times zero is still zero. My understanding is that the bias ratio (multiplying factor) of the Quaife is about 2:1, whereas the Torsen is about 3:1. For reference, an open diff is 1:1.

To do what Warmonger would like to see would require a full locking diff, like a Detroit Locker, which has a bias ratio that is in effect infinate:1. Needless to say, a full locking diff isn't highly recommended in a street driven FWD car...
