    My Friend followed this on his E46 M3...still complains that it rattles with his Spec clutch and flywheel.

    I was not aware they made a single mass steel flywheel...

    I don't believe that. Every car I've ever owned had a SMFW and didn't chatter or rattle. MT with SMFW does not equal gear rattle for all cars.

    GeorgiaTech335i how bad is the rattle? Have you tried raising your idle rpm with INPA? Did you get the SAC clutch and flywheel?

    True enough. I over simplified/overstated. DMFW are for NVH (not noise only) which manifests as MT rattle on some percentage of cars.

    It's getting better. The first day it was very bad, but has gotten better with break in. I haven't had to use the AC much, so I'll report on that later. I do have a lot of chatter on engagement, a little more than I expected with a full face. I haven't raised idle yet. No-SAC.

    I've been dealing with some other issues, so I haven't paid too much attention to the clutch, but overall I'd say I'm happy with it. Engagement point is 10x better than the ACT.

    That's exactly how I felt about mine. I couldn't get past the chatter though. Wait till you're sitting at a stop light this summer with the AC on. You'll hear the chatter from inside the car with the windows up Click here to enlarge

    it happens on the auto too now. around and over 700whp. time for a 6mt and smfw i guess. or something else. seems the 6at is a dead end for this much power

    I can't deal with that. Has anyone tried using gear oil to fix it? This sounds good in theory:

    Gear oil will not get rid of it, the only thing that would is being able to bump the idle up a little bit. If you can't deal with the rattle then stick with a DMFW, at times the rattlle isn't baI or even presetn, but with the AC at low idlle, its loud there is two ways about it. There is always a price to pay to go fast

    I hear you talking, but I'm pretty positive you haven't tried it. I, too, could speculate, but I'm looking for experience. The link specifically talks about solving DMFW->SMFW gear rattle on BMWs, so their fix is certainly plausible.

    Simply living with it or staying DMFW is an obvious option but we are looking for new solutions.

    I might give it a try, nothing to lose and the car is undergoing an overhaul anyway. The rattle isn't exactly unbearable and if nothing helps the rattle then it's still a very minimal sacrifice to make for power. Realistically speaking it's impossible to find a comparable platform where so little comfort has to be sacrificed for performance.

    I hear you speculating, but I am pretty positive I have tried it. It doesn't work, its like putting ear plugs in while cutting down a tree with a chain saw, you are going to hear it no matter much you try to soften the sound. There is no "new solutions" this is not a "new" problem. This is how it is if you want to run a SMFW with a transmission designed to use a DMFW. You pay to go fast, sometimes this means dealing with annoying sounds. I hate it as much as the next guy and did everything I could to fix it, including changing gear oils and trying "cocktails" even when I knew it wouldn't work. Guess what, it didn't work. But hey, go ahead and give it a whirl its not my money. I apologize for giving advice on something I have direct experience with. Carry on

    @Ak335i is the noise you talk about why you can't make more power past 700whp or due to the slipping tranny?

    both.. i could go higher with knock sensors disabled but at the same time this is around where it starts to slip as well. basically over about 670ish whp it begins and gets worse causing more cyl6 misfires above that level

    In Dzenno thread on this forum about MT-90 multiple people say they tried the cocktail and it didn't help. It's like 2/3s of the way through I think.

    The cocktail and a permanently raise idle is the best you can do. The noise isn't that bad...

    What did he use to change the idle? I don't know if you can do that with INPA.

    Now, outside of the one guy who blew his motor on RBs with misfire detection off, do we know that turning misfire detection off has any bearing on knock detection and correction?

    He didn't. If i remember correctly he said the UUC cocktail barely helped on the N54 if at all and that was the steel and not aluminum FW. I've yet to find a way to raise the idle but I haven't looked hard. If you find out how to let me know as I think a 1k idle would fix the rattle. A higher idle will also make a stage 3+ clutch easier to engage not that it is hard.
