Hi all , My 911 just makes me "happy" with problem after problem , transmission ,window switch , key , tune by 911tuning (that actually makes me happy) but here is the news , today first time ever I saw after full boost hits at 4k rpm or so the rpw go up , the car not going any faster , clutch slip , I tried to step on it on 2nd gear feels ok , so I tried to make it slip different ways it might did it again but definitely not like a first time , so after talking to previous owner and finding the post of the owner before we find out that the clutch 10k miles old , 5k miles the car wasn't making power to destroy the clutch . and that why I'm posting this post , what would you do ? yes the clutches go bad , could be an engagement issue ? like fork ? pin , something in between it's impossible , but just in case . or just replace it and forget about it ? even if that will cost me . I'm tired to spend the money on it , to much since I have it , and I really start enjoy it after retune by Markski . I haven't decided yet if it worse it . Thanks for inputs guys . sorry for my english .

 

Have a shop look at it......and if the clutch is gone then replace it with something other then a CM.

I have the CM stage 3 and hate it.....

 

I inspect it 1000 miles ago while I rebuild my transmition , looked ok with ton of life . How much shop will charge for replacing the clutch ?

 

They need to drop the transmission, so maybe a $1000+. Matters on the shop obviously.

 

Sounds like $4 the all story

 

So do you have a new clutch installed? or the factory clutch?

 

I have cm st3 , according to car history 10–12 k miles old , half of that milage the car was weak

 

I have the sameone when they installed it did they change the flywheel to a new one?

 

yes , they did that the link to add

How many miles on the clutch?

 

10–12000 , the car has 48000 right now.

 

I would check the slave and the clutch fork to see if they are binding and not releasing all the way. Because throwing another clutch in there with other problems will repeat the results. It is usually obvious when your clutch is toast. I bet you have other issues.

 

do you think it's possible ? what can go wrong there ?

 

So i looked at the original ad and there was no indication of a new fly wheel with the CM ST3 clutch. If you are on the original fly wheel that could be the problem. Around here most people that go to ST3 clutch ended up with LWFW and complain about the noise. I'd go back to see if flywheel was ever changed and go from there.

 

brand new FW was installed , I asked the owner . low rpm no boost the car drives fine , whitch is tells me it's eather one of the disks , am I'm wrong?
