testing lsd on a 93 rx7
hi guys, what is your favorite way to test the lsd on a 93 RX-7, and what way would work?
would you...
A) do a burnout on pavement and look for 2 solid lines
B) do a burnout on half grass/mud and half on the pavement to see if you can make a streak on the pavement
C) Jack the rear of the car up, put the e-brake down and spin one wheel and see if the other wheel turns the opposite way
I tried C but it does not really work for me, must you spin the tire really fast or something?
also, what type of lsd is on a 3rd gen rx7 and does anyone know what the difference is? (example 1.5 way or 2 way lsd)
thanks

i have read about torsen differentials and most people say that when one wheel is off the ground, the other cant be given power such as if you were to corner extreamly hard and one of the rear wheels leaves the ground. Does this also mean that test C wil not work?
How strong are stock fd rear diffs? has anyone actually blowen one out? i think most people (even the guys who drag except for jimlab and his monster of a V-8) can use the stock diff cuz its soppose to be strong.
anyone have any ideas?

A torsen will limit slip only when being driven by the ring gear. You can spin wheels by hand and it will work like an open diff but when power is applied by the engine it limits slip.
You are correct about its inability to limit slip when one wheel is off the ground. Torsens have a torque ratio (around 3:1 on the RX I think?) meaning that they will send (about) three times the torque of the spinning wheel to the one with traction, three times 0 is 0
The Torsen operates similarly to a Quaffe which is described very well in this month's Sport Compact Car (with the Silvia on the cover).
