Around 230 Ft Lb's of torque I know the Std 215 Valeo one just starts to slip so I would say you would't want more than 200 thru it really

When I phoned Valeo technical they told me that the 1.9 Mi clutch was good up to 275 nm which is approx 202 lb ft.

An update in my case, the standard Mi16 clutch once it had bedded in will now just about hold the torque my car makes. The rolling road suggested 211 ft.lb so the figures quoted for the clutch torque capacity are about right.
It is right on the edge though, slip it much in traffic and get it hot and it really is marginal under full boost in higher gears.

However I can cope with it and so rather than remove the box again to fit the SPEC clutch I have I will wait until I really need to fit it.

I'm having the same problem now. We had the car rolling roaded and it 255ftlbs and the heavy duty 405 td clutch is starting to feel the burn.

Has anyone fitted a spec clutch as I'm looking to order one.

Cheers

Apart from an exhaust manifold I have the majority of the bits now to build an engine that should thoroughly test the limit of that clutch....

I had a helix in my old T16. Never once gave me issue no matter the amount of abuse given. Also was surprisingly smooth to operate.

@Tom Fenton & 205turbo

Do you guys have in the meanwhile experience with the Spec clutch ? - I'm also thinking about to purchase this clutch due to same problems as you had.

I've got one on the shelf but not actually used it. The customer service when I bought it was good, they are in the USA.
