Clutch set question?

[Jamo]

Det är för att det inte ska spricka isär ju!

Sounds strange that the spec3+ wont handle the torque of a gt3076.
Bad mounting, oil/grease on the flywheel/lamell from a broken crankshaft rear gasket?

My bad english again...sorry for it!

No spec 3+ is not a good product repeated reports of slippage on RS2 / 3071 power

Like Marc said south bend is way to go, im running they st5 in my car with no problem and if some thing will go south Andy will take care of it, best customer service ever. Spec, I think I broke 4 of them and never got close to they advertised TQ nr, and of curse no warranty.

I can try and see if we can get a sachs GB or something. Preferably the 3b / 7a flywheel kind. with sprung sinter 4-puck, what do you think? best option up to 700-800 nm?

Strange, mountingfails?
I know one guy who using it with 500 hp and 570nm of torque?

Your new to the forum search for spec 3+ and count the amount of failures and issues with pedal to the floor

It seems that im the only one here that his spec 3+ has not yet slipped or got damaged!
after all the documentations though im not sure i will be trying spec again.
probably will be going to the good old sachs sinter...

I also found an old email i had from Javad,saying that the spec3+ should be able to handle 500ft/lbs crank (around 400ft/lbs whp torgue). So 600Nm is about 440ft/lbs, which is why probably it is still active in my case.
It is interesting though why so many other spec 3+ have not.Could it have been a bad batch?

@prosty: do you think sachs sinter with dual mass flywheel will be much to harsh as a daily driver?

Im not going to be going more than 600Nm but i do want to set my mind at ease with the clutch...

[prosty]

I had the SM sinter with 4-puck and it was not hard at all to drive. The DM flywheel is much smoother so I'm very confident you will have a pretty smooth ride!

You need the 724 plate and another 4-puck sinter for the DM flywheel , the 724 can handle more power than the 707 but the flywheel is the stop for power imo.

[A80Avant]

yes i know. Since im not going to be going more than 550hp anyhow,do you think the flywheel would be up for that? and about 650Nm with a sinter sachs?

A80Avant: i shouldnt run my car withg DM and these powers.. when you change clutch, change from DM at the same time ( only my own opinion though, but boring to break something, because the gearbox is not so funny to take down as you know)

[A80Avant]

yes i know. i should do that at some point.
My mjor problem is that if i change the DM flywheel, shouldnt the whole be balanced again?

If so, then noone can do that in Greece.I would have to arrange to have that done while being in the UK.Maybe arrange something with Aerled in the future or something.

[prosty]

well.. both no and yes, just balance the flywheel instead to make it as good as possible. Those numbers you are putting out isn't 100% needed of a balanced engine (but always good to have) I've gone with 600hp and no balancing at all. Works perfectly

[A80Avant]

so all i would need is a single mass balanced flywheel? thats not bad. I could make it all into a kit with the sinter. something to concider for the future!

That would be very interesting. Even with the organic pressure plate for people that would not be aiming for such bit torque figures.
Cheers.
