any updates on this????

Maybe I can request something like that.

On a twin disk, does anyone else have a vibrating sound during engagement and downshifting (normal driving). Mostly happens from 1st to 2nd gear, but also 2nd to 3rd gear. Always makes this vibrating sound when I downshift, like brakes do when the rotors are warped.

It's been doing this soon after the clutch was installed. I thought it would go away after break-in but it's still there after 2000+miles on the clutch.

Can it be warped plates that some have complained about?

 

When you installed the clutch, did you line up the balance marks? I guess there are balance marks on the flywheel, pressure plate, and floating plate (I think). I am going to be installing one next week and that is what I read about.

Of course, I could be completely wrong.

 

I didnt read the whole thread so if this has been said just ignore it....from what I have heard about the exedy twin disk the problem has something to do with the fact it uses a STOCK throwout bearing. Doesn't make alot of sense why they use a stock throwout bearing which is designed for a single clutch disk for a dual..but what do I know? I have heard of 3 seperate clutch failures due to this...from a mitsu tech...just throwin in my 2centS

 

I wish people would stop rating clutches in HP holing capability. It doesn't mean jack ****. The torque capacity is what matters. Yeah, I bet you the exedy can hold 1000HP if it's in a low-torque high-rpm motor. But I'd also be it wouldn't hold 200HP in a diesel truck. HP is a function of RPM, but torque is torque no matter what. My little rant...

Oh, and I have a Cusco Twin, and for the guy that asked, yes it is made by Exedy, it has Exedy stamped right on it.

Consider this... Exedy designed the stock clutch, and they hold the patent on pull type clutches. I think they'd know if the throwout bearing can handle itself with their twin clutch, and I think they'd include an upgraded one in the kit if it couldn't.

I agree, the balance marks must be followed, and the more I've read into it the clutch disks need to be phased. I wrote a thread on my Cusco clutch review and I talk about it more in there if you want to search.

I was also wondering, is the Exedy Twin two full-face disks, or are they of a puck design? I've never seen the exedy in person and I'm just curious.

I concur with Rez90.. that exedy sucks ***.. i broke 4 of those with 330whp only

 

I would hope so, but not for nothing the stock clutch sucks ***** or did you forget? Maybe thats the problem with our clutchs in the first place, the fact that they are the pull type and it does not appear to disengage properly (Buschur Racing)> Either way I was just stating what a factory tech told me his experiences with the twin disk was, thought it might be of some help....Besides Mitsubishi also says there stock clutch works great....LoL..just because a company says something does not mean they are right. Exedy has not proved anything to me about the quality of their products, it would make sense that the just re-use a piece they already are mass producing (cheaper) than designing a new one, as long as it works OK.

 

Besides Im running a ACT clutch, so what do i know??

 

Yes, but on the same note...

There are plenty of people here praising the ACT clutch, it is pull type and ACT uses a stock throwout bearing.

The Pressure plate's clamping force is higher in an ACT than the Exedy twin, meaning that throwout bearing would be under more load in an ACT setup than an Exedy.

I'm not trying to say that the Exedy clutch is superior either, I just want to learn more like everyone else. And the fact of the matter for me is this... I bought my Cusco Twin before all this Exedy b1tching and bashing began. Do I regret my purchase? No because it has held up fine so far. If it never fails me than I've got no reason to tear my car apart again and replace it with another brand clutch, and if it does fail in a short period of time I'm going to contact Exedy first, and consider my options second.

You are right. The marks need to be lined up during the install. I didn't install the clutch though, a shop did and they were aware of it before the install.

All I can say is I won't spend this kind of money for a clutch that doesn't even hold the kind of torque you can get out of the stk turbo, but I also can't afford an RPS. It will prob have to be an ACT.

 

It has 2 full face discs. The hyper single has a 6 puck.

 

Interesting, my Cusco Twin (made by Exedy) has two 6-puck disks.
