With respect, the Quaife replaces a weak stock diff as part of the improvements re 'getting the power down', I'd be inclined not to wait for your stoc diff to exit the trans case with the power of a t/c motor behind it...you could be placed in a big $$$$ hole if you push your luck! 
At what point would a person have to worry about the gears stripping off the main stack? HP numbers of course. I just read about a race cougar that had to get hardend gears for just this purpose. Its seems if they had the quaife diff they could stall out at 3000 and already be in the powerband maybe then yield better numbers than the vortech.
