Peloquin diff kit/what kind of Transmission does a MKIII with a TDI have?

[lucasone]

Hi Guys,

Anyone with a modified TDI knows its hard to get keep the front tires from spining. Any additional traction is a good thing.

Concept1 is selling "Peloquin 80% Diff Kit TT498.080" for $165.00. It's recomended for 020 transmissions 100mm axle flange. Is that what a MKIII TDI has?

Here is some more info:   
   
Peloquin 80% Diff Kit TT498.080
For clutch cable type 5 speed manual gearboxes. Supplied with installation tool.
This kit increases the factory 20% anti torque steer effect to 80%. The 80% Pelolok kit helps
eliminate torque steer and inside wheel spin. The 020 80% Pelolok kit can be installed
without removing the transaxle. It will also work with the Peloquin differential,
as well as the stock factory differential. This kit is for the 1984 and up 020 transmission.
Please note: This kit is recommended for 020 transaxles with 100mm CV flanges.
"The first reaction is that people really notice the difference in the steering response under power.
The car steers tighter - on the throttle the car goes toward the apex. The people who live in the snow
and the ice really love the added winter traction". This kit is great for those with a
limited budget or race classes that do not allow a full limited slip differential.

AHU TDI's have hydraulic clutches. 02a transaxles

02A's from what I understand are much more robust than a built 020 to begin with.. Vw smartened up when they put this bad boy trans behind a TDI. They got smarter on the 02J.. however 02A's are still better than an 020.

But do they have any limited slip at all? I'm going to have to do this in mine eventually

Don't quote me but the O20, o2A, O2J and O2M all have factory limited slip diffs. The CV flange that you pull off, it has springs on the end that press against the diff gears and thats what creates the possi affect. Yeah its not much but its something. I think the stock percentage is 40%.
The 80% kit that TT offers is what I have on my Rabbit. Its great, easy to install and is noticable. The kit just adds more pressure to the springs, so more pressure to the diff gears creating more friction/LSD to total of 80%. .

The best way to get more traction is to do the Peliquin or Quafe or a spool.

020 "limited slip" is around 20%. It's not a true lsd. Just adds preload to both sides of the diff to keep rattling down but acts like a weak lsd. None of the vw factory transaxles have an lsd as far as I am aware.

Yes, true.

[nathan_b]

if it acts like a lsd, it IS a lsd... lol
when the diff wants to slip one way, the spring attempts to limit the bias.

albeit a weak one, it is a lsd none the less.

The early 020 had 2% preload, the max they came from the factory was the 20 mentioned above. I have the 80% kit and changed the cv to 100mm inner. I still fried the driver side cv as it backed the bolt out since it was too long. I got it replaced and ground almost down to the snap ring on the inner cv on that side and have no problems now. With the 100mm inners the cup is deeper and you are not supposed to have that problem. Only the 90mm inner is supposed to do that and usually on lowered vehicles. Mine is stock height. Just a warning to you if you go that route.

I had mine all winter and really didn't notice any traction impovements. It would just spin both.

Lucas, what can you expect from summer tires in the snow? Lol I have an 81 FF in my car right now (2% lsd) and it spins the right tire on dirt.. Lol

its not a true LSD.. the springs have the same pre-load at all times..

an LSD will sense a tire spinning, and will engage, and lock the clutches in the differential.. (thats what makes a LSD)

the VW unit is not LSD.. its a way to keep the stub axles from rattling.. it was in no way intended to be a LSD.

if you jack up one side of the car with it in neutral, you can easily spin one tire by hand.. if you have strong hands, you can twist the drive flanges opposite ways with the trans on the ground.

the differential in a VW has never limited my slip. once you got a tire spinning, it does nothing to correct it, besides keep it spinning.

(its like 10% LSD if anything.. theres no way its more than that. because it doesnt ever limit the slip)

ive driven lots of cars with LSDs (NX2000 and SRT-4 are first that come to mind) and the LSDs in those cars feel completely different, because they are ACTUAL LSDs..

[8v-of-fury]

Broke VW has tested these springs that reduce rattle in all the 020's.. And they effectively provide around %20. The reason the other cars actually felt like a 'real' LSD is because their % was probably higher.. To where you wouldn't slip it under normal conditions like a stock early 020.

I think an 02A provides similar.. But its weak spot is still the same as 020's.. Just a wee bit stronger.

[rallydiesel]

I think the 02A is quite a bit stronger than the anemic 020. The O2J and the O2A have only minor differences.

I agree, much less trouble with reverse and 5 th. I've changed a few 2nd gear syncros, and other misc. issues, but generally they are much tougher than the 020
