I was just browsing and found this :

from the description, it sounds like the same as the zexel-torsen in the 4th gen cars! I heard that is a good diff to get, but nowa days they are all real high milage!!

Another question about these (assuming they work the same way). From what I have read about this, and the torsen, is that they apply the torque from the slippery tire, to the tire with traction instead. What I dont see that they do, is lock the axles together!

2 days ago, this kid came down to Dunkin Donuts in his mom's 2002 LS1 trans am (his moms, so stock). I am assuming this car had the zexel-torsen. It was an automatic.

However, he started to do a brake stand, and both tires lit up! And they both were spinning about the same speed. Then, he went on to start drifting around the poles in the parking lot, and the car went sideways just as easy as it would with a spool LOL.

So, how is this possible? Because I have read many sites about how the Torsen works, and they all say basically the same thing. That the wheel WITH traction will spin 6 times faster than the wheel without. So essentially, it would look like a one-wheel-peel because one tire would barely be moving.

 

That is how a Limited slip works, read up on it a little more. They were ment to improve traction and not for burn outs.

 

So a torsen or other worm-gear type posi is no good for burnouts and donuts??

If thats true, I wonder what that LS1 car had in it that worked so good? Would a locker be better for burnouts and drifting ect??

 

Yeah a locker would be better since they always keep both wheels spinning at the same time. A torsen wouldn't be too bad, you'd still get both wheels spinning. The only time a torsen doesn't spin both is when there is a HUGE disparity between traction of the wheels, like if one is in the air or something.

 

I have yet to try out my tru-trac. It's hard to beat the price, that's why I went with that over a clutch style one. (and no clutches to wear).
And yes, LS1's have torsions, just like the tru-trac. Works pretty similar to a clutch style as far as traction and burnouts go.

Only problem is on sheer ice. If one tire has ZERO traction, it won't lock the worm gears. It needs a bit of traction, then it'll lock up.

 

How about pulling up on the hand brake to fake it into having "traction" to get the wheels turning together? Asking for ice/snow conditions, not burnouts

 

I read that the hummer owners manual recommends to lightly ride the brakes if you get stuck with a wheel in the air. I guess the force of the brake friction on the airborne wheel will be multiplied by 6 as traction on the ground ridden wheel

So, a torsen will still work for posi burnouts and drifting, because then they are what I need to start looking for. I wouldnt mind a locker, except that all I read is about how shitty they are on the road...
