Re: Clutch Opinions
 

I'd love to drive someone's car that has an un-sprung disc if anyone would be so willing. Just to try it out. Also in my opinion, even if it's hard at first, you can typically learn to drive it smoother over time once you get used to it. Mine was reall off/on feeling at first, but now I can drive it fairly smooth.

I think I'm going to call ACT today and see what they have to say. Right now I'm leaning towards a 2900 with either a full disk or a sprung 6-puck.

Re: Clutch Opinions
 

How old is your clutch? From what Ive heard puck clutch wear out faster. mabey just try a new/ different 6 puck and your pressure plate. Im running a clutchnet sprung 6 puck and a act 2600 pressure plate. I love the feel of it, I think it engages better then my ACT street disk.

I'm glad your not thinking twin disk. Twice the price and twice the problems in my opinion.

Re: Clutch Opinions
 

^great sounding advice. Thanks.

Re: Clutch Opinions
 

Well I just got off the phone with ACT. Just going throw these numbers up here to reference later.

2900 w/ sprung 6-puck = 590tq.
3100 w/ sprung 6-puck = 609tq.


I seen on another forum, someone utilized an ACT 2900 PP, but a different sprung 6-puck that actually shielded the springs which I'd never seen before. I thought it was interesting as every once in awhile you see springs that pop out and do some damage. But I'm also a bit concerned about using other disk's with another persons PP. Different thicknesses could create dragging issues in higher RPM's.

Anyhow, the ACT guy for the most part sounded like a 20 year old dude who didn't really know all that much. He told me the pedal pressure should be slightly more then a 2600, although I keep reading that the new 2900's have a better designed PP and the pedal pressure is actually slightly less then a 2600.

Kerry, let me know if I can ever go over there and just feel what your Pedal Pressure is like so I can make my own judgement.

Im home now and the rest of the night so you let me know when you want to stop by.

Re: Clutch Opinions

Re: Clutch Opinions
 

Yup you're right, here's the picture of it.

Re: Clutch Opinions
 

Well I've been researching this non-stop, and at this point in time I'm pretty much sold on getting an ACT 2900 PP combined with the above Clutchnet disk.

One of the guys on the link forums, running 10's at about the same trap speed I was at, still weighing in around 3050, has been running the 2900 w/ street disk, but said it stinks pretty bad at the end of his runs, leading him to believe he was pushing that combo to the edge, and it may have been slipping slightly during his runs but not enough for him to really notice. So sprung 6-puck with that PP should be a pretty solid combo it sounds like.

Only downfall is possible dragging in high RPM'sk (which is an issue with pretty much all single disk clutches), but I honestly don't see the need for me to rev all that high considering my powerband (7500, maybe 8000rpm shifting).

Thanks for all the input, I think I got a winner.

Re: Clutch Opinions
 

congrats on the decision. Now get that thing ready for the track!

Re: Clutch Opinions
 

I think you'll be happy with your choice. I really like the feel of mine.

Re: Clutch Opinions
 

Woot! And let's get about 5 cameras at 5 different angles of you're runs this time! Haha

Re: Clutch Opinions
 

I think we proved that my car performs better with the cameras off ;)

Re: Clutch Opinions
 

hopefully your master/slave/lines, etc, are all ready for the 2900!

I remember that shit.... haha. It held fine though!

Re: Clutch Opinions
 

Good point. My Master cylinder was replaced just a few years ago., but not sure if I've ever replaced the Slave. The lines, well they don't leak now, and I have one of the pieces replaced with a SS line. So for now I think they're OK, but I'll have to keep an eye on them for sure.

Re: Clutch Opinions
 

Yeah I'd definately watch out for the slave. I had one good/hard powershift with my 2600 after I got it and there went the seal in my slave..

Re: Clutch Opinions
 

I ran a 2900 in my car with an organic disck and it did not last very long. I don't like to slip mine too much either. i am not sure why you don't want a twin disk, if you talk to Steve maybe he will let you try his out. I would let you try mine if my car was running.

Re: Clutch Opinions
 

I drove enough twin disk evo's to know I don't mind them at all. 6 puck ones too. I like them, and that will be the next clutch I get. Hotter they get, the better they grab. You can also shift them faster, and with 2 disks instead of 1, you get nearly twice the grabbing force, despite the smaller size of disks..

Re: Clutch Opinions
 

Most of the twin disc setups for DSMs do not drive anything like the ones for the Evos. The Evo twin disc's are usually very very easy to drive while the DSM twin discs can take a lot of getting used to. Any twin disc for a DSM or Evo will usually have a light pedal that makes shifting quick easier.

I like sprung 6-puck clutch on DSMs and Evos though. I have seen 2900s cause the throw out bearing to eat up too many tranny cases and their own pressure plates to ever run one.

Re: Clutch Opinions
 

I don't want a twin disk because I've simply heard that on DSM's, they just aren't that smooth. They also cost about as much as a tranny. And I swear every time I read about someone installing them, they seem to always have issues and have to modify crap to make them work.

Re: Clutch Opinions
 

The Evo ones drive nice, but they cost even more than the ones for DSMs and they don't handle as much power as you would think. You usually have to goto a triple disc on an Evo, if you plan on making a lot of power.
