I looked at it too. The disks are nearly full size. Seems like extra unwanted rotating mass on the input shaft that could contribute to lock out. Would be interesting to hear from people who are running it.

The clutch that caught my attention is the Carbonetics Twin. Looks like a very good clutch with minimal noise and excellent modulation. Only drawback is that its really not meant to be slipped in any significant way, e.g., at the drag strip. I was told that for launching, just quickly release the clutch and it will engage smoothly.

The QM with the hydraulic release bearing looks interesting.

 

Thanks for the helpful input man . Any further advice you could contribute?

 

I was looking at that quality piece also, but I'm still a little unsure on the carbon aspect of it all and also the rebuild pricing. I think my decisions are now between the new quartermaster, HKS, maybe carbonetics, and maybe exedy. Leaning towards the quartermaster right now. All in all, I can deal with a bit of noise rather than lock-out. Which is worse right?

 

Any updates on this? I plan on ending up in the 420HP/380T range (maybe a bit more, but not far off that). My plan is still a very quiet exh (even if it gives up some HP), so I'd like a clutch that is also quiet.

 

Blackdsm sent you a PM

 

What would you like to know about the Qm 8 leg?

 

How easy is this clutch to drive in traffic, actual traffic not just at a red light behind a car.

How many miles do you have on yours currently, has the driving characteristics changed since new, if so in what way. Is this clutch able to be slipped a little to allow a less harsh engagement if you are just putzing around town?
