I think I understand the open differential fairly well. I understand with the open if one wheel is slowed the other wheel will spin faster (linearly increasing). If the wheel is slowed to a stop the spin will is 2x the rotation it would be if neither wheel wheel was stopped (assuming constant shaft rotation speed).

Now my questions are:

1) Why is it on an open end diff if u hit the gas hard and leave rubber the right/passenger side wheel is the one that spins? Why always that wheel?

2) On a limited-slip diff if you hold one wheel still will the other then also rotate at twice the revolutions of when both wheels were free.

The limited slip as I understand it uses something akin to clutches which put a "pre-load" on the axles to make them spin together......so in essence I am asking if spider gears also make the free wheel/axle in a limited slip diff turn 2x as fast as the held wheel or does LS simply slow down the axle with resistance on it (thus the free wheel rotates at same speed as it would if both wheels had no or equal resistance).

Thanks to all the Brainiacs!!

 

Answer # 1: The wheel on the right always spins because that is usually where the people you are trying to impress are usually standing!!!
