Testing a 80% ZF Limited Slip
The Porsche repair books say hold the LSD body in a vice and see how much torque it takes to turn one axle stub.
914 book says 50 ft/lb.
911 book says 80 ft/lb.
Also found a note that says put one axle stub in a vice and check the torque at the other stub, LSD body "floating". Should measure more than 25 and as high as 75 ft/lb.
I measure 150 ft/lb. using the one stub method.
and
40 ft/lb. if I check stub to stub.
Comments?
Thanks,
Ken
