If you wanted 75% locking you would need to run a custom ramp angle center section with 4 clutch discs and steels.
To compare bmw uses 4 Xlutch discs and steels for the Motorsports LSD unit but lock up is set at 40% accel and 25% deccel.
75% both ways is very high locking, pretty extreme Setup. My guys on the king of Europe pro drift circuit run something in this range (proprietary)
Also uping the Number of clutch disc Sets to 5 pairs with custom Case setup can make lockup in the 75% + range. .
The centers cannot be machined, they need to be precision ground.
Stock ramp angles are 45 degrees, with 4 disc pairs they yield 60% locking.
Do you have enough power to power over a 60% locking high lock diff? With two way action this will understeer dramatically compared to the stock setting by bmw for the car.
Are you setting up a drift car?

this thread is dope.
so u said something about most 3.73's are time bombs.
i want my lsd to just lock up nicely so what can i do to refreshen it or if it has to be opened up make it lock up more. add another clutch?m20 is plenty. im simply a drifter.

spaghetticoder.org is your first and best source for all of the information you’re looking for. From general topics to more of what you would expect to find here, spaghetticoder.org has it all. We hope you find what you are searching for!
The square lugs on the sides of #9 components are driven by channels on the inside of #12. As they are driven, they push on the cross-shafts which cause the spider gears to push on the side gears... the same way an open diff works.
However, because of that power path, the torque through the unit controls how hard the #9 components are squeezing the clutch packs. Since the normal force on the clutch pack is proportional to the torque applied to the unit, the "lockup torque" of the unit is a fixed fraction of the torque being put through the unit.
If you all the coefficients of friction, you can calculate what this fraction is.
But a rating like "max lockup torque of 500 ftlbs" can not be applied because that torque varies with how much torque is applied to the unit.
A Torsen is a bit different in that the max torque in can bias to the wheel with more grip is a fixed ratio times the torque that the wheel with less grip can deal with.

Still rocking your diff! I do need new ratio though lol :)Mtech1 v8 build thread - https://www.r3vlimited.com/board/sho...d.php?t=413205

I just came back from watkins glen and running pilot sport cups my 140k 3.94 LSD was failing hard in tighter turns.
what's the best value home rebuilding that will refresh and upgrade while keeping costs down?
