Limited Slip Differentials
Pardon my ignorance but I'm not able to find this info by search of the archives. I know that my C4 6sp has a Dana 44 rearend and I believe that it has a LSD. My question is what is the percentage lockup on a stock 89.
I love the way my Vette's rear diff works and would like my 05 MB E55 to work similarly.
It employees a computerized traction control to limit wheel spin but I think that it would deliver more torque and quicker times if it had a true LSD. Several aftermarketers make LSD for the E55 all differing in lockup percentage.
\Thanks

lockup percentage implies a torque-sensing differential (or viscous). the limited slip in corvettes is a system of serrated metal plates. there is a tiny amount of torque-sensing built into plate-style LSDs just from the bevel on the spider gears pushing the side gears apart under load, but it's still mainly a preload-breakaway situation. in other words, not comparable.
however, if you want more limited slip action in your MB, tighter is better. it's difficult to make a torsen too tight for street use.
it seems an extreme and costly change considering it's not a racecar. on the other hand, some electronic brake application as an intervention does work extremely well with torsen diffs. the weak point of the torsen is if one of the two tires is unloaded enough, it basicallys act like an open differential. it needs some load on both, and the brake application would do this. (for instance, the T2R for mustangs has clutch plates in the torsen diff so keep the 2 sides loaded together for when the inside rear becomes unweighted in race use.)
