I've recently supercharged my e46 330 and need to upgrade my clutch. The stock clutch can't handle the torque.
I'm not really interested in lightweight flywheel setups and plan to keep the stock dual mass. I'm leaning towards the Sachs performance organic clutch to maintain a basically stock setup (just stronger) as this is my daily driver.
Anyone with experience with the Sachs, how are the pedal effort and engagement?
Any others I should consider? The Clutch Masters sintered kevlar seems to be gaining in popularity but I haven't seen it used with the stock flywheel.

| Sachs preasure plates are weak (to the point of arguably being defective for e30's). I lost 2 due to broken attachment ribbons in a mater of months with only a stock engine in a 325i. (no autocrossing only track and street--no holeshot starts, no abuse). The ClutchMasters are reworked Sachs units with beefed-up (triple) ribbons going from the shell to the preasure plate itself. --Ron

| Rogue Engineering and JBRacing. But they are not dual-mass. I missed that part in my first read of your post. I will go with the Rogue flywheel and the v12 PP when the clutch goes on my 540.

| For my E36 M3, I went with the UUC M5 Stage II Performance Organic. It took me many months, if not a year, to get the clutch bedded in so that it was quiet during street use. The problem was brisk starts from a dead stop would make the clutch material squeal. I used it about a month on the street before the first track event, then many track events thereafter with daily driving between. I would have expected it bed in and become quieter much quicker.

Have you checked for and removed your clutch delay valve?

Interesting the UUC Performance Organic would squeal like that. I wouldn't have expected it. I've heard the sintered kevlar may squeal if you try to slip it but I always thought the organic linings were supposed to be quiet.
Interesting you brought this topic back up when you did as I'm finally about to commit to a change in my setup. After more time with the SC, I'm not really noticing any slip. It has slipped on 2 different occasions since February but I've chalked that up to the darn SAC mechanism. At this point, the issue driving my change is the fact that my stock dual mass flywheel often sounds like a jackhammer after startup. I believe the halves have separated.
I spoke with Autoscope again today about my options and, given my desire to avoid another dual mass, they recommended a JB Racing aluminum flywheel paired with a Clutch Masters FX100. They don't seem overly fond of UUC over there these days, too many problems I'm told.
I wish there were a slightly heavier flywheel option for me but there's nothing available for my 6-spd that I can find. Zionsville makes a pilot bearing carrier which might allow me to adapt something like UUC's moderate lightweight steel flywheel for the 5-spd but I don't know if it's worth it. Rob Levinson actually mentioned this possibility to me but I'm still waiting for him to determine if this is really doable.
CDV removal was my first mod over 4 years ago.

| I triple checked that my clutch is the Performance/Organic. However that does not mean it is the same material as the clutch used on the E46 6 speed. Sounds like you've already done a lot of research. I suppose Rod isn't planning on a Steel version of the 6spd fly. Have you tried Findanza (sp?) the company that makes the UUC flys? I'm sure if they made it UUC would be selling it. Simply getting rid of the SAC system may help your problem.

TxZHP (9/3/2008)
At this point, the issue driving my change is the fact that my stock dual mass flywheel often sounds like a jackhammer after startup. I believe the halves have separated. It is interesting that you mention the jack hammer sound. I have an E39 540 6 spd. At idle in neutral with the clutch pedal out, I have this sound like something is broken and rattling around in the trans or the clutch. If I push the clutch in it goes away completely. The sound intensity is varaible and even absent at times even with the clutch out. It is never there when in a gear and moving. I was wondering if yours sounds the same?

| Frank those are the exact circumstances for gear lash, which is a lightweight flywheel problem. http://www.uucmotorwerks.com/html_techtip/techtips/tranny_rattle.htm Have to noticed whether tranny temp is the difference between the time it makes the noise and doesn't?
