heating up the liquid is not what you wanna do.. that would cause the silcone to unlock on you

also what i gathered from my research a while back online


Here's some good reading if your bored. From the Miata guys, http://members.aol.com/solomiata/MiataVLSD.html

A VLSD is made up of thin perforated plates that are suspended in a silicone fluid. The plates shear the fluid as the wheels rotate at different speeds. This shearing can equalize the different wheel rates thus limiting slippage. The VLSD only provides a 15-20% locking function when new, so they are not really meant to be a performance item. I have found that the locking action of the VLSD takes a moment to activate when one wheel starts to slip so it usually takes affect after you have already exited the corner. They are really meant to help you get the car moving from a dead stop in slippery conditions and not a performance aid. The VLSD works just fine for it's intended street usage but it will effectively stop limiting slip, from a performance point of view, at some point as the plates can break, the silicone fluid can leak and the tolerance between the plates can wear.
