Valeo Xhd High Perf Clutch Kit

[sargo]

Hi Yall,

Anyone had anything to do with these before? Looking to replace a clutch behind a 6 speed to handle about 300KW. According to the blurb they have 70% more clamping power than the original clutch (which is also a Valeo clutch).

They caught my eye as they are only $600 and utilise the existing flywheel.

Any feedback would be appreciated.

This wouldnt be the same clutch that GTP use?

XHD Clutch Kit

To me it seems as though the Cover Assembly is an 11inch Unit, clutch plate shown is a 5 paddle, ceramic, with a higher capacity centre hub using 6 (I think usually they are 4) torsional springs, to allow for a the harshness on the drivetrain.

Although the picture isnt clear, the Cover Assembly, does not seem have and modifications to the pivot points of straps, and relying upon having to be 0.5 inch diameter increase over a standard XR6T Cover Assembly which is ten and a half inch or '1050'

How they can accurately determine, the clamping pressure this HD unit, my concern would be daily driving would be a nightmare, and shuddering would more than likely. No more progressive take up of the pedal, it would be heavy, in or out, meaing....give yourself 10meters when taking off a set of lights, allowing for the slingshot-straight-into-the- -of-the-car-in-front-

Ceramic button clutch is going to shudder the sh*t out of the driveline, not to mention the fact that you will prematurely wear out the clutch if it is ridden on the take up.

How can they state that its a 70% increase over std as Darren said? Do they have a clutch dyno, I think not.

I've used several ceramic button clutches over the years. 15 years ago the buttons I used grabbed too much and made it too hard to drive comfortably on the street. Then about 8 years ago someone put me onto a button made by another mob and the new Carbotic buttons made the car totally drivable on the street, no judder and takes 500rwhp+ no problems on a small 8.5" cluctch.

Different brand button materials certainly give different drivability and button tech has come along way. You should find someone who has used this clutch and check how smooth it engages.

Carbotic materials are fairly expensive, they are superior to kevlar and allow slip, Porsche used them on their Cup cars, but as a compromise, a combination of organic and ceramic friction surfaces (see below) would generally offer a decent and daily drivable performance clutch.

3rd from the top, is the SSCC.

Dampening between the backing plates provides modulation, torque capacity is significantly higher, but engagement will be slightly harsher compared to a organic unit.

Thanks to all who replied, there is a wealth of knowledge on this forum. I am looking at the non ceramic Valeo, I too have been advised that the ceramic model is no good as a daily driver. Keep those cards and letters coming....

What are the details with the non-ceramic valeo your looking at, provide a link and Ill take a look.
