The Sachs 890 was fitted last thursday and I have driven it on track a couple of times through the week plus lots of b roads.

I've got the duel mass fly wheel, If I go for the Sachs would you recommend I change the fly wheel?

I have a 996 turbo x50 running 1.4 bar, not sure of the power but the Sachs 740 nm clutch I had in it could not cope, so I now have a Sachs 980 nm clutch in which is fine.

Use on their conversions, you need something rated

Suggestion
Speak to 9E or Fearnsport to see what they use on their conversions, you need something rated to deal with the torque, BHP isn't the killer for clutches.., if you track it a lot you might want a single mass, but for street use and a soft smooth pick up, a dual mass is better as they are damped..

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
23 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

No difference in feel, only slight change is clutch bite point is a bit further up on the pedal.
Hi guys,
One for the more technical PHers. Which clutch would be best for my 996 turbo x50 tuned to 673bhp. Do you think the 964 RS would be okay or would you recommend something else.

The guys at JZM will be able to tell you exactly what you need. They fitted my 997 Turbo with a good quality upgraded clutch.

Sachs should would fine
Would I notice any difference in the feel of the clutch. Don't want to fit anything that will make the car undrivable.

Sachs feels stock but if you go for lwfw you have to get used to it as its a bit grabby with a lwfw. What clutch were you running before? Even a new OEM clutch would not hold hard third, fourth, fifth gear runs even for one pull with 673 bhp lol!

i've recommended the gt3 rs 4.0 flywheel as i've heard it has all the benefits of a lwfw without the downsides which are transmission chatter and a slightly grabby clutch. I have a lwfw and love it but my cars no longer a daily driver and wouldn't be much fun in stop start london traffic.
With the sort of power you have the engine will spin much more freely as there is less inertia with a lwfw and your throttle response will also greatly improve. The GT3 RS 4.0 lwfw apparently has all these benefits bit is still quite civilised in terms of transmission chatter etc so you have the best of both worlds. Hope this helps.
Just been looking at reviews on the GT3RS 4.0 LWFW and some are saying that they don't last long and are prone to failures. Does anyone have experience with the above. Also I have read that the conversion creates additional rattle/noise from the transmission. Again advice very much appreciated.

best person to speak to is someone like Ken at 9e. He's done mine and it definitely rattles and transmission chatter but if you learn to be in correct gear all the time i.e. do not labour engine there is very little noise. I read the GT3 4.0 flywheel was much better in this respect but suspect its a characteristic of all lwfw
Speak to 9E or Fearnsport to see what they use on their conversions, you need something rated to deal with the torque, BHP isn't the killer for clutches.., if you track it a lot you might want a single mass, but for street use and a soft smooth pick up, a dual mass is better as they are damped.. see what Ken has to say, a stock GT2 unit might be strong enough.., or a Sachs upgrade friction/pressure plate..
I had a Sachs 890 as part of my conversion from 9e. I have (for the moment
) a lot less hp than you have, but gob loads of torque.
I believe they are using the same clutch in much higher power applications than I have. Haven't noticed any difference whatsoever compared to STD 996t clutch.
I've got Sachs 890 from 9e also with no problems, standard fw (I think), been dyno'd with similar bhp figs as op's car. Clutch feel is acceptable, biting point q high & a little hard to judge and needs revs, overall though it's not too dissimilar to oe, and it does not slip when on the power which is the main thing.

From your description sounds like you may also have a lwfw. The Sachs on its own should be no different to stock and doesn't need any more revs.

Exactly.
If your 890 sachs doesn't feel 100% stock theres something wrong.
If you haven't changed the fw then I suspect it could be that !
Thanks for all the advice.
The Sachs 890 was fitted last thursday and I have driven it on track a couple of times through the week plus lots of b roads. The end result is that I am very pleased. I ended up not going for the lwfw as it is primarily used on b roads. I really cannot notice any difference in the feel of the clutch other than all the horses (673hp) are now getting to the wheels
.
Thanks again

I meant the 890
