Dave,
While I'm still trying to fully grasp the concept of the servo motor and it's purpose in this application I can offer a small tidbit of experience concerning differentials. I once had a camaro with a typical "open" differential and it would do wonderful one sided burnouts. After deciding to upgrade to a true limited slip type diff I opened my unit to find the spider gears eaten away almost to the point of failure!! The moral of the story here is dont expect to use a typical automotive type differential for an application where there is can be a great difference in axle speeds as the internal gears are not meant to handle it long term. I suppose one could be developed for this purpose with spider and side gears that are bearing supported but most car diffs are not so. I can't speak for the torsen type diffs as I have no experience with them but I don plan on installing one in the new mustang I just bought so I'll let ya know!!
