new source for a torsen diff!

and they do other nice stuff too!

 

[NorthloopCup]

Cheap @€750 too!

who will be the first to give it a go.

Would this need any machining to install then?

 

[JackD]

Interesting to see how much shipping, import taxes and maching would come to, surely will still be a few hundred cheaper than other available options still?

Only the crownwheel if they mount it the same way as Quaife diffs are. It's basically 4 ball bearings and a bit of loctite on Quaifes for the jc5.

Eu so no import taxes......

 

[JackD]

So roughly £550 for the diff, say £50 postage and what, £150 maching costs?

 

[bloke]

tempted...

Nah more like £60-£70 for the machining. That's about what Quaife charge

 

[JackD]

Looks like quite a good deal then, £650ish compared to £1000 plus for quaife or gripper

Yeah definitely is. It all comes down to how it performs. I can get grippers and quaifes at half right prices, but even I'd be tempted!

 

[bloke]

even more tempted...

Is this a case of you get what you pay for? How can it be that much cheaper than a quaife atb?

Cheaper materials and cheaper machining costs. Potentially. But it says it comes with a lifetime warranty.

I have a Torsen diff on my Mazda. 19 years old and it still functions as it should!

It'll outlive the shell

 

[Ph1 Tom]

Bargain! My mate runs a torsen in his supercharged MX5, feels the same as a quaife tbh.

Just to clarify my above statement regards the cheaper materials, I'm not meaning to a lesser spec, I'm meaning in terms of material cost to purchase. It's a large billet that's needed to manufacture a jc5 diff.

What actually is the difference between a torsen and a Quaife?
I thought the Quaife was a torsen as the name implies the priciple ie TORque SENsing

This is a good video

 

[bozothenutter]

very good video, but are a torsen and a Quaife the same...or is rthere a difference?
from what I have seen of a Quaife it uses wormwheel/gears

 

[franx]

anyone gone for this ?

[bloke]

funnily enough emailed them last week, not heard back yet. will probably ring them in the week.

 

[franx]

I've noticed there are two warranty comments on their product: One is "lifetime warranty on craftsmanship and material" , the other on their Facebook page is: "1 year unlimited warranty + 4 years warranty upon material or manufacturing defect." :neutral:

 

[marinemackay2003]

This is what I got back from them for anyone who is interested

Hi Chris,
The shipping fees by air mail(international priority service) is 50 Euro.
Yes, our LSD is fitted by pressure and can be secured with 2 steel balls and loctite, similar to what Quaife does.
We have 2 short ratio final drives to match this LSD, one in ratio 14x63(4,5) which has already the grooves to match with our LSD and a second one in ratio 12x63(5,25) which hasn´t the grooves. Enclosed you´ll find the 14x63 final drive with the grooves.
If you want we can fit the LSD with the crown wheel with a surcharge of 30 Euro.
Do not hesitate to contact us if you need further information,

Thank you and best regards,
Victor

There is one guy on Renaulttuning that has bought one:

Can you translate in brief ?

keep up at the back...mine turned up ages ago!!!

from what I have seen of a Quaife it uses wormwheel/gears

The diff in the video is a Torsen T1 which is what I am assuming the source of the new diff also is. These are said to lock more fiercely. The Quaife AFAIK is a T2 type of torsen diff, and may potentially have ramp angles on the gears set so that the diff does not fully lock

To quite Wikipedia (yes, I know it's not the best source):

1. The original Torsen T-1 (Type A) uses crossed axis helical gears to increase internal friction. The Type I can be designed for higher torque bias ratios than the Type II, but typically has higher backlash and the potential for Noise, Vibration, and Harshness (NVH) issues, and requires a precise setup/installation.
2. The later Torsen T-2 (Type B) uses a parallel gear arrangement to achieve a similar effect. There is also a specialist application of the T-2, known as the T-2R (RaceMaster).
3. The latest Torsen T-3 (Type C) is a planetary type differential, in that the nominal torque split is not 50:50. The Type C is available as single or twin version; the Torsen twin C differential has front and center differential in the same unit.[2]

However, where are you finding prices of £1k for the ATB? On my RST I am finding prices of £650 with it being less if I had a RWD Escort! I'd have thought it would be a similar price for a Clio.

Scrap, that, just taken a look! It seems other Renault owners can get a cheaper diff! I wonder why there is such variance in price between the 197/200 and the JC3/5 gearboxed Clios.

It's because you have to start off with such a large piece of material on the jc5 atb. Shite design tbh.

Just saw a pic. What a strange old design!
