LSD talk. Wavetrac vs quaife vs mfactory vs peloquin.......thoughts/experiences?

[Guy_H]

Yep, only downside is the price.

I wish VW would follow some French FWD specialists & start to offer mechanical differentials as standard or options.

according to This , mfactory does make a "metal plate" LSD in 3 forms. I would guess this means "clutch pack" ? Care to comment on this - $882.41 is a tad cheaper than $3k

They are for the manual transmission
The manual transmission has more and cheaper (all below $1k) options from all these manufacturers (Peolquin, Quaife, Wavetrac, etc)

Switch to a DSG discussion and the entry price for bias torque units is $1,500~$1,600 USD
Then you have to get it shipped to Oz, $500? (If you're familiar with USA/CAN shipping rates)
Then you still need to get it fitted

While I love my DSG transmission,
I can't help thinking I should get a cheaper manual car for the track
It would give me more/cheaper options

Good observation and sorry I forgot the latter of this thread was about DSG boxes not manual.

A point though , is that the DSG equivalent LSD is not much more expensive than the manual equivalent. So the $3k quoted before if its for. DSG would be a similar price for a manual box

bennjamin,

We worked with mfactory for 6 months, we even sent differential centers to their HQ in Asia - believe me, they have no plate VW diff - regardless of what you read on the internet.

Here is a challenge for you - see if you can order one (even a manual one) if you can get a plate version from Mfactory, i'll buy it off you for double what you paid!

Hey Guy
In no way am I dissing your knowledge or experience, in just stating they are advertising such products for sale. I'm surprised that they ( or any company) would advertise something that doesn't exist ?
I'm close friends with the Australian distributor of mfactory , I'll send him a pm and see what he says.


Btw , for mine and everyone's learning - would a Torsen diff act the same as a clutch plate diff under most circumstances - IE no lift of wheel etc ?

[Guy_H]

bennjamin, if you mean Leonard (Mfactory rep) - then he will tell you (with utter disgust) that they don't exist.

A torque biasing differential goes open when the inside wheel (one with least traction) gets light, you lose grip like a stock differential.

It's better than stock, somewhere in between stock & plate (or clutch) differential. On a track (as mentioned above) there is several seconds in it (TBD vs plate).

Yeah that's him - I'm an admin off another site (ozhonda.com) and he is a trader there - wont waste my time then. I owe him a beer so ill bring it up next afternoon meet.

What's the life expectancy of a clutch diff with normal driving? I'm assuming it depends on the amount of lock you dial in too.
Having taken the gti around a track pretty much dead standard it's shocking with traction control off. Inside wheel slips under harder angles and theres no way to push the car into lift off oversteer with throttle control- it simply under steers like crazy.

Cool - we certainly have expressed interest to Leonard if they will make a plate diff, I'm sure we can sell some!

All the ones we use for the street / track have steel friction plates in them. at 30,000kms they look like brand new so I don't have any direct experience with having wear times on them. One of the manufacturers told me 200,000km's on street use, or 40,000km's on the track.

Experimenting with carbon plated ones later this year.

Quaife & Peloquin wear heavily on the track, you end up with a heap of play. On the street, they will probably last as long as the rest of the car. I don't think they like the extreme on/off load conditions.

[Tim]

I havent used one but the wavetrac diffs have a "clutch type" mechanism that stops them from having no drive during low axle load conditions.
