SMF How much vibration??

For you guys who have the single mass flywheels, how much vibration or noise do you get at idle? Any other bad things about a smf setup?

just changed to SMF, can't tell any difference at Idle but I did pick up a vibration when under a very light pull. I think that might be a u joint.

When yall say noise, is it like bad/something aint right noise, or just different, to be expected noise. Does the sales rep know about all this? (i'm guessin he does)I'm counting nickels for the smflywheel and clutch as we speak. In other words, you're still happy with the install/product choice? Thanks, Jay

Haven't noticed any vibration, do have a little throw out bearing noise till the pedal is touched. But definately better than the DMF!!!!

thewellman, in normal driving there is no noise at all. But like just about every clutch out there, under certain conditions it will make a noise (not a bad noise but a noise). Like a 250 hp tractor with a 32 foot harrow behind it, if you have it in the ground and reach the end of the field, throttle down to make a turn and throttle down a litlle too much, when you get on the throttle again, you can hear the clutch make noise for just a second or two. I and everybody that I know that has gone over to a SMF loves it and would never go back to a DMF. Also once you do the swap, in the future all you have to do is resurface the flywheel and put on a new clutch, no more replacing the Dual Mass Flywheel at $400 a pop plus the clutch.

Talk to rubberduck about valair. I did before I got mine and was very happy with the results. I do have more tranny noise at idle. It's definitley the tranny itself in my case. Under way, she's not bad at all. And I fully agree with plowhand, I would NEVER go back.

the noise you would be referring to would be gear clatter, torsional vibrations passed from the engine to the main shaft, rattling the gears in nuetral, a couple of things can reduce the clatter, slightly raise the idle, or install a fluid dampner.
