800 with a new flywheel...

btw, its about 1300 for the shitty exedy twin that does NOT hold up well in evo's.

and the reason I would need a carbon is if I'm spending that kind of money on a clutch, why not just spend it once and get it over with?

 

You do not drive an Evo.

With a flywheel your cost should be around 600, so where did the last 200 go to?

Carbon clutches are not a good choice for the street, they need heat. 1300 dollars for an exedy twin disk and 3000+ for a carbon clutch is kind of hard to say "you might as well". There are multiple other twin disk setups that arent 1300. Hell dave in this thread got his QM for 800, the same that you paid for a single disk 6 puck.

 

I think you might be mistaking what car he drives. He recently put down mid 500whp on meth from what I hear, and it is indeed a evo, and from what I understand clutch prices are alittle higher than the dsm clutches.

As far as which clutch to go with, I spent 650 shipped for a fidanza flywheel/ ACT 2900 w street disc. It was cheap and I knew it would at least hold 500whp, if I have to put a 6 puck in it then so be it. The 2900 is so much lighter than the old 2600 PP I had in there, and the drivability with the street disc is awesome, real smooth. Had I not been in such a money bind from all the motor costs I spent I would of gone with a twin disc.

 

thank you

and yes, 835 shipped for an act sprung 6puck/extreme plate, with an act flywheel.

There are multiple people on the forums running much diff shit than the dsm guys are used to. Every exedy twin ceramic I've seen in an evo is luck to hold any more than 50 trim. Maybe its cuz we make more power than the dsms?

btw I'm actually still sitting here at the shop taking a break from swapping cylinder heads(bad guides=lots of smoke in the other one). i should have it up and running tonite.

 

Andrew, he is posting in a DSM specific thread where people were talking about what clutch to use on their DSM, it seemed natural to assume he had a DSM and was speaking from experience.

While I appreciate hearing how the clutch worked on Evo's, I dont necessarily believe that it will be an issue on a DSM.

There arent many high roller DSMers out there, so it is difficult to find alot of reviews of it but here's two making 700awhp through an exedy twin:

sorry, I didn't realize that since this was a dsm thread, that I wasn't allowed to post my input since I drive an evo.

BTW, I've met and talked to you in person before, and I don't remember you being so confrontive...

 

Im not, just hearing that an ACT will hold up to what I want to go for is funny and I was arguing my side. Are you the one who worked at the junkyard? Im not a dick at all, pretty nice guy for sure, just I know tons of DSMers who do nothing but smoke their ACT's multiple times in a season when going for the power levels that im going for. There arent many DSMers that run the Exedy because it retails for 1700 dollars, but from the reviews that I have seen, it seems to hold up incredibly well and is very street friendly for a twin disk. That sucks that evo's dont do well with them, it definately makes me continue searching for positive DSM reviews. Aside from this one case in this thread of an exedy killing itself due to bolts backing out I have yet to see a negative thread about it.

And its not that you're not allowed to give input, just I assumed you were talking about its application in DSMs, and referring to how it worked out in Evo's to try to back up the claims. Its hard to get how a person is reacting to comments by reading text, so don't think I'm furiously typing away out of anger, I'm simply having a little ball busting session as I really dont think the ACT route is a smart one at all.

 

I will hear that and agree. I wasn't trying to say you were being a dick, thats why I used a made up word, one would not come to mind that expressed my feeling. The drivetrain layout is similar but design very diff b/w dsm and evo, so I would venture to guess that it loads the cars differently, that and I think the dsm weighs in a bit less?

Regardless I'm not fluent in dsm, so I'm not going to argue with you about them, as you will win. In the evo world the ACT street/extreme(what you dsm guys would call I think the 2600?) works great until about 450tq or so, and even then it will be fine, so long as you don't try to launch it a bunch.

The exedy twin does not seem to hold up very well in the evo drivetrains at anything over the 450tq mark that I have seen, and I do not like how much it chatters. Just my opinion.

Carry on

 

The torque levels that I would like to reach are higher than any single disk DSM clutch will handle time and time again. I will be using a direct shot nitrous system along with a relatively high hp turbo system. I just have seen the single disks wear out too quickly at the levels that im going for, so the twin disk seems to be the only option. Unfortunately the chatter is part of the twin disk game, so while I doubt I'll like it, it'll have to be something that I live with. I definately wish more people used this clutch in DSMs so that I would have better feedback, but when other twin disks can be had for 500-700 dollars less, its hard for most to fork out the Exedy price tag.

 

Re-torque your head studs boys, double check it. I went wot yesterday, hit second and the car was missfiring like crazy! Scared the shit out of me as I immediately thought the worst happened like possible bottom end failure, or rod damage. I limped it home, and compression tested the motor. It was 155 across but #1 cylinder wouldn't hold ANY compression. I figured I popped the head gasket as it is an oem composite, with arp head studs, and I've been running 27-28 psi so it could happen. The car is now all torn down now, pulled the head tonight and low and behold, several head studs around that #1 cylinder are wobbly as can be. They backed out some how and it only took 3 turns to unthread it, they were barely in there.
