Please explain what this is? Do I understand correctly that it decreases wheel spin on rapid acceleration? Does my 93 SE have it or is it an added mod. Thanks

 

It does just what the name says. It limits the slip of the wheels, without LSD once a wheel starts spinning almost all power goes to that wheel. With limited slip it limits the amount of power one wheel gets thereby giving each wheel around the same torque.

 

It comes on 92-94 SEs. I believe this is the holeshot advantage that these cars have on acceleration against other cars with similar HP.

 

What's up Dan? I hope I can explain this right. Yes you car features a Viscous Limited Slip Differential. It uses a liquid that becomes more "viscous" or becomes thicker as it gets agitated. This liquid is housed in the differential that seperates the left and right cv joints. When one of the wheels starts turning at a rate that is different than the other wheel(ie... left wheel is spinning like crazy and the other is not doing anything), it starts to agitate the liquid. The liquid starts to get thicker and that starts transfering energy into the passenger side cv joint. As the liquid gets thicker and thicker, it will transfer more power to the pass side wheel. Up to about 25% I believe. This doesn't sound like much(it's not) but it's alot better than having an open type differential that doesn't transfer any power to the other side.

 

As jeff said, it basically just transfers power "from the wheel that slips to the wheel that grips"..
I forget who coined that phrase, but that's what a LSD does. it helps in snow and wet and off the line on hard acceleration where wheelspin is a problem.

Basically think Posi-trac from the old big block V-8 days.
