Clutch-based LSD will transfer 100% of the torque to whatever wheel has traction. The harder the wheel resists spinning against the carrier (as in the more traction it has on the ground), the harder that side's clutch pack gets compressed. Under power a functional clutch-plate LSD is 100% locked. Period. Clutches wear out. But it doesn't happen overnight, and when it does, it still leaves you with an open diff. I think it's perfectly acceptable for the front end. I wouldn't wheel with one in the rear though.kevinthefro wrote:My understanding is that number .8 (80%) is not a gear ratio but a torque split ratio meaning the maximum torque split is 80:20. If one wheel has less than 20% of the traction then it will take all the energy and spin like a one-legger.
One wheel off the ground requires a 100:0 torque split - 100% of the torque to the wheel with traction and zero torque to the wheel off the ground. The only thing that does that is a locker and that's why ARB can charge what they charge.
Last year I had the idea of improving traction by swapping in a 370Z rear but after many hours of digging through off-roading forums and road-racing forums, they all said that viscous, helical/Quaife, Torsen and clutch LSDs will not send any torque to the wheel with traction if one wheel has zero traction. I didn't believe it until I looked up Quaife and Torsen's manufacturers' documentation online and they said the same thing. Both wheels have to have something to push against.
Some people pointed out you could trick a helical or Torsen into sending torque to the wheel on the ground by riding the brake with your left foot. So that's one thing a helical can do that the electronic limited slip can't do.
It would be interesting to know under what circumstances you or anyone else is losing traction currently, and then talk about whether a helical LSD will do anything above and beyond the stock electronic limited slip.
If you already have a compressor, and someone did the electrical and plumbing for you then $200 more for the ARB is a better deal.docwatson wrote: I am not sure I would put a front LSD in the R51. I would drop the extra $200 on an ARB over the $750 for this LSD.
Absolutely true, if, as you said, you are under POWER. If you are trying to crawl over rocks slowly, the lifted wheel will spin.stascom wrote:Clutch-based LSD will transfer 100% of the torque to whatever wheel has traction.
