We run the quartermaster twin disc. Unbelievable clutch. Clutch takes some getting use to if you are going to put miles on it. But, the level of performance is second to none. Has held up to some serious abuse and even teaching a 19 year old girl how to drive on showed no signs of heat or wear. That particular clutch is now in a 1G running 10.6@136. No slipping and super high quality. The pressure plate had to be countersunk though. As the clutch was designed for a Ford Cosworth Sierra. That car uses a hydraulic throw our bearing. For the money I say go with it and the devo tuning flywheel. The chromoly flywheel is a phenominal piece. My next clutch in my mirage will be this clutch after the 2900 goes out. We wanted the tilton for the 2G but couldn't justify spending $3200 for the clutch.

I run a exedy twin disk and I love it It took me some getting used to but It never slips at all and my car makes 545lb of toqrue. Exedy comes with the pressure plate and flywheel pretty much everything you need to bolt it on. The shop that built my car Showdown racing is running the same clutch in their race car thats powered by a 42r and ran consistantly in the high to mid 8's. Alot of the evo guys run the exedy and are making tons of power too.

Why not go with the PTT since it's cheaper and made by the guy who originally designed the clutch for QM. THe PTT is also quieter and has a better tob., only diffrence is you have to reuse your ring gear or buy a new one($80).

[biglady112]

Do you have first hand experience in it being quieter? How about knowing that the throw out bearing is better? We got out Flywheel and Clutch for $800. Seems reasonable to me.

Have you seen the PTT TOB design? It is the only company other then tilton that offers a TOB for aftermarket clutchs. It is made specifically for the clutch and also helps reduce noises. Yes I have first hand experience with the PTT clutch being quieter then the Devo clutch. If it wasn't for steve from PTT there would be no QM PERIOD.

[biglady112]

I was looking for a better more detailed reason than that. For anyone in the future who may want to use this thread to help them decide on a clutch. I know the differences but others may not. Just put the information out there with reasoning.

More detailed then being told by people who have first hand experience with the clutch being quieter? Steve Fox designed the clutch(18 years he was with QM) and a few years ago he opened his own company making specialty clutches. The design of the throw out bearing is specific to the multi disc clutch rather than using one made for a standard clutch. With the QM clutch you either clearance your stock fork or you buy one from devo that has already been clearanced. The devo kit is $1200 retail and the PTT setup is $1050.

The PTT does come with a steel flywheel, but you have to reuse your ring gear or buy anew one($80) available from jnztuning.

What it comes down to is buying the complete package(the PTT setup) or most of it(the QM).

Think of it as a Mustang...Ford made a good thing when they made the mustang, Carol Shelby Made it better.

So what would you rather have, a mustang(QM) or a Shelby Cobra(PTT)?

You say it can handle tons of abuse and I'm curious how many passes at the track or season(s) it has lasted for ya, also about what does one of those things run anyway, and can it be rebuilt and if so, how much?

Sorry for all the questions

Can you post a link for both vendors(Devo tuning,PTT) Thanx!

[outlawdsm]

The devo tuning clutch comes with everything when you buy it. Clutch, flywheel, new TOB, new fork, and it just bolts straight in. Where are you finding the PTT for $1050, i only see it for $1250.

All that info is correct except for the flywheel info.

The PTT setup comes with a chromoly flywheel, and you must have the plastic sleeve OEM TOB so you can take it apart and press the new PTT TOB into the OEM backing plate. When I installed a QM, there was some decent room between the clutch fork and clutch, it did not need to be ground down really but I did it anyways just for precaution. The organic disks with the PTT setup are very quiet and the drivability is great, but they don't seem to like 500ft/lbs, so the ferametallic disks will need to be used, which squeak nicely and are grabbier. The QM setup, IMO has pretty good drivability, quite a bit of chatter but nothing you can't get used to, though I'd hate it in downtown traffic. I would definitely go with either setup to be honest. Steve did a great job designing both clutches. For the PTT, I would definitely go with the high torque pressure plate and ferametallic disks though for added comfort in case I wanted to make more and more power down the road.
