a 90 jetta should have a 20% stock "lock" to it from factory.. Is it the original transmission? The front left tire should still help out..

So it would seem you are just gunning the throttle and expecting traction??

http://brokevw.com/difftest.html

It takes 26-19ft/lbs of torque to break the right tire free from the left.. SO! this means you need to be super light on the throttle and have the engine make no torque.. and it will give traction to both tires :)

Nice! LSD on tha cheap. New part added to wish list...


thats not an actual LSD.. FWIW.

Really? does the term dead horse mean anything Kev? ;):D Shall we call it a slip limiting shim kit? SLSK? It performs the same duties to our transmissions as an LSD would to a normal differential.

The 80% requires nearly 140ft-lbs of torque. That is more than most of our cars make. This would pretty much ensure a near fully locked diff.

its still an open differential, with conical washers, that WERE NEVER DESIGNED TO BE USED AS AN LSD..

sure, you can bolt everything tight, and make everything wear ALOT faster, and have a "MINI-SLIP", but no.. its not an LSD.. sorry guys.

i actually DO know the difference.

It works but it wears out eventually. In muddy grass I still could turn both tires, on asphalt I never could tell. The guy told me if you are autocrossing or racing they usually need replaced every season. I had almost 40,000 on mine and it still did the muddy grass test the day before its end.

Since when does the intended use matter to us wrench wielding people? :P I bet every person ever has used something to do something that it was not intended for, it'd be an interesting study for sure. Mini-slip, limited slip.. they both are not a full locker.. and provide the same action by different means..

Its widely known what the difference is, but it is also widely known that they work at what they were designed for. (the shim kits I mean)

For $100 40-60,000miles would be alright by many I think.. as Peloquin is still selling them ;).

for sure. for sure.

But who wants to spend $7-800 on an 020!? lol. Spend less to swap in an 02A or 02J, and your ahead of the game. however more "work" is required.

Well the peloquin isn't really posi trac, according to the guy on the phone. I guess from what he said it won't lock them up together, if you use the 80% kit with it he said it is almost a positrac...which peloquin is the only one you can have both the diff and the 80% kit in at the same time. From what I gather the wavetrack is the only true posi unit we can buy for the 020.

I think the 02a and 02j are better trans, but even those don't come with a diff in them to help, so on top of the cost of the trans you need to get the same peliquin unit to help with traction.

I don't know if I agree Lucamod. I had the 02a behind the AHU tdi when i drove it before i pulled the motor for the swap, i drove it hard. A 1900rpm clutch dump (turbo fully spooled and cranking out 150 ft.lbs) would leave two equal strips of rubber. So it must have at least the holding power of the 80%.. which will hold ~140ft.lbs.

Right, as long as it has load on both tires they will both grab.
 If one tire is on ice it will be the only tire spinning.

 I tried a wavetrac, shifted into second in the middle of a left turn and gunned it, must have been a little sand on the road.
 Car went straight instead of turning, both tires pulling/spinning and no tire left to stick to the road and guide me, ha.
 Takes a little to get used to.
 As soon as I let off it turned.
 A wavetrac will pull you down the road with only 1 axle, ha.

an LSD will actually lock up both tires if its the right kind of LSD..

cluched lockers, once you shoot power to them, will lock both wheels, provided there is resistance on atleast ONE wheel.

even with an 80% kit, there is NEVER a full lock, unless you have equal load (pretty close) on both wheels..
