Twin disc clutch [Merged 11-6]

[PSI NRG]

Heres the ultimate question... For a street driven car that sees the track a couple times which clutch would be better? Twin disc or 2900? I chose twin disc because many people told me a 2900 is rediclous if you are drivng in traffic due to the fact that its either in or out. I was recomended the exedy by Showdown motorsports in toledo so thats what i went with. Regaurdless any high horsepower rated clutch is not going to be very streetable and to me the exedy seemed to be the best option. If you want a clutch thats easier to drive get somthing with a sprung hub not a soild one. Spec makes great clutches what have sprung hubs which should make daily driving less of a hassle. I would have got a check but I got a REDICLOUS deal on the exedy 1100 bucks!!!! That includes the flywheel as well!!! Good luck on your choice!

the fork comes with it. it is a good cheap twin. It makes more noise when the clutch is pushed in. What you here are the discs flooping around. The drivebility is ok at best,yes i drive my car on the street but it is no dd. There is no chatter at launch it just slips very little and then grabs. Pedal is about the same as a 2600.

Did you buy it from Devo tune or from PTT?
How much did you pay for, I think devo tune listed 1100 for the 6 bolt and 7 bolt, and the it comes with the flywheel gear ring right?
Which type of disk do you have, mettalic or organic?
So it has sound when the pedal is off and when the pedal is on the sound increase right?
Thanks for the info, I thought nobody would care and reply to my thread

I slipped ACT 2600 with street disk, then used 2900 with street disk for 4/5 times and then didn't change the pressure and used 6 puck disk with it, and because I slipped to many clutchs with the 2900 the 6 puck didn't hold, some of them I made breakin for them and some of the clutchs I didn't have time because I had to race the next day.

I used 3200 with 6 puck disk because I didn't have money for the twin disk by that time, ended up broke my 2nd gear ratio in wheel spin and my tranny is fully racing build by Mr-John Shippered and then fixed the 2nd gear with a ratio from Mr-John Shippered and broke that again in the dyno because very long time doing runs, which really costed me alot, I broke inter shaft,output shaft, had to change the input shaft because some said it might be bend, changed all the bearing of the shafts, bought HD 3/4 conversaion from Mr-John and special thanks to him because he sent the stuff as fast as possible and helped me out and undertod my fool English

He recomanded redline heavy anti shock proof oil, I had used BG ultra gaurd and he said this is the most thing which will help not to break stuff, and a good light pressure clutch will hold, I feel the 3200 with 6 puck is over kill for the tranny

Now I'm moving to DEVO TUNE twin disk because it;s the cheapest
less pedal pressure almost like stock, no chatter, shift better and smoth shifts at high rpms, will help not to break the tranny, crank walk will take more time for the 7 bolt guys
You'll get light weight clutch disk and flywheel.

There is only one thing which I hate for the TWIN plate disk, which is the sound at idle with the pedal and without pedal, some type when you press the pedal the sound go and some type the sound rise up.

I had alot of chatter with 3200 and 6 puck disk, with 2900 and 6 puck I could handel how to drive the car without chatter

I'm still waiting for good answers about PTT or DEVO tune clutch before I order that

The only noise i hear is when the the clutch is disengaged. it's silent when your sitting at idle or driving. It's not hard to drive with low pedal pressure easy to slip but very snappy. Adam at Devo gave me a great deal on it $1000 but i picked it up since i live dow the road. It has everything you need ringgear is on the flywheel ready to go!

Actuallt I would be happy if he will give me the same price he gave you because I need two sets, one for my Colt and one for my Eclipse both with f5m33 2g tranny with 6 bolt motor, so I need 6 bolt FWD clutch, I ownder if they sell the clutch for FWD or what modification I need to make if the clutch is for AWD, I think I'll have to change the flywheel gear ring.

Did you get the clutch with the modified fork and special release bearing, which clutch did you use mettalic or organic?

I'm looking for the mettalic because it would hold more than the organic as I read
So there is no sound at idle when the clutch is off and on at idle only when the clutch is gonna disengage, this is the clutch I'm looking for actually with good price

I'll try to contact Adam and see hope he have it at stock because I tried sending him so many e-mails but didn't get an answer

Thanks for the info guys

 

[alqatan]

Guy as you know English is my 2nd language I let my friend to call Adam at Devo tune and he told him it's only availble for AWD not FWD and if there are two ways to get AWD tranny and use their clutch or to get custom FWD flywheel and this might take like 6 months or maybe less or more he can't tell how much time does quarter need!

What is the difference between the AWD flywheel I think only the gear ring in the flywheel, my question if I put the FWD gear ring in the AWD flywheel and use the 2g f5m33 tranny with awd clutch, is this gonna work out?

I asked my mechanic and he said this should be worked but he is still not sure and he said the AWD flywheel is smaller than the FWD flywheel

The reason I want to move to Devo tune twin plate because I've slipped ACT 2600 with street disk and 2900 with street disk for 4-5 times, and slipped 2900 with 6 puck because I used the same pressure of the street and it was old enough, now I got two ACT 3200 with 6 puck none spring ended up breaking JS last stage FWD tranny first I broke the 2nd gear ratio and then I broke the 3rd gear ratio in the dyno, this isn't my 1st time breaking tranny stuff.

Alot of people told me using twin plate will be less harsh on the tranny and will shift much better and better 60ft which will lead me to get more hp.

the reason I need Devo tune clutch because it's cheap compaired to any other twin plate and I need two of them, one for my Eclipse and the other for my Colt

HELP ME OUT GUYS I DON'T KNOW WHAT TO DO OR HOW TO USE THE AWD CLUTCH IN THE FWD TRANNY

I was thinking of using 3200 with street disk and I'm sure I would slip it after a while
Today I ordered the 6 puck spring so if I slipped the street disk with 3200 then I'll replace it with 6 puck spring, I heared the spring is less harsh then the none spring

I have alot of chatter right now with none spring, I'll remove it and try street disk if it worked I'll be so happy, if not I'll use the spring 6 puck

But I still need the twin plate, I love the twin plate it will let me shift better and this is what I care right now

And I don't want to slip the clutch from time to time

With the twin disk setup it is all about the disks. Choose the wrong disks and it will sound like belts squealing every time the clutch engages and rattle like a marble in a tin can (bronze disks). Get another type (carbon) and you'll be spending $600 or so on a rebuild within 6k miles, even if you don't abuse it, actually it would probably last longer if you do abuse it.

The twin disks are great but I've not seen the holy grail as far as materials for the disks go. To me the best bet would be to find a clutch guy that can make their own disk and have two feramic disk installed in a QM setup. The feramic clutches hold more the hotter they get and don't mind you slipping the clutch. The cost of the disks should be less than carbon clutches.

With that said, anyone that buys a twin disk setup that's not making more than 500 whp should have his or her head examined unless they are trying to one up their friends or have something cool to talk about at the car shows.

You cannot put FWD ring gear on AWD fly. What you need to use that twin plate clutch with FWD tranny is an original 1989 mirage turbo flywheel. The car comes with a 215mm flat flywheel. You just have to shave the surface .150 and drill six holes. I have done this and it works great. problem is finding these flywheels. they are very rare. only 1200 were imported to U.S.

Which clutch brand have you used with this flywheel?
I might be able to get this flywheel it's 6 bolts and I think it comes with f5m22 tranny if I'm not mistaken, I think it comes with 4g61T

By the way yesterday I've compaired OEM AWD 6 bolts flywheel with FWD fidanza 6 bolt flywheel and the only difference I got is the gear ring width, the FWD is taller the AWD is smaller which makes the AWD flywheel smaller in diemeter than the FWD and I think the only difference is the gear ring.
My mechanic said he ordered his brother wrong AWD insted of FWD flywheel and his car didn't start so he had to pull the tranny out and use OEM gear ring with fidanza and everything went fine but this can't be done in ACT because the gear ring and the flywheel come all one piece

I wonder if the Devo tune or PTT flywheel would be the same as fidanza and I'll only have to change the gear ring, if it's like ACT then I need custom FWD flywheel

 

[alqatan]

Come on guys I know we wanted to compair both, actually I can't tell if I have to move to twin plate just because it would shift better and I won't be able to drive the car that much in street I heared people are replacing their clutchs after 10000 or 15000 mile, I don't want to pay that much then replacing new clutch or returning back to single plate.

I know the Fidanza flywheel would hold more than ACT flywheel with ACT street disk so what is the binifit of using twin plate clutchs over single plate.

I want to know compair both in
Cost
Drivebility
Pedal effort
Noise
Disengagment
HP holding
How long would that last.

I know the cost of twin plate would cost more than ACT 3200 street disk and fidanaza flywheel
Drivebility the ACT has better drivebility because the 3200 has less pedal pressure than 2900 almost like 2600 and the twin plate has almost like 2600 pedal effort and the twin plate is like on/off clutch, I don't have chatter with street disk and 3200
No noise with street disk and 3200, I heared there is noise in the twin plate while disengagment
HP holding this is the problem I can't tell how much would both hold!?
The ACT will last more and cheaper to change the twin plate will cost more and will die more if drivein in street.

Question is if I have almost like 600 wheel hp car, does it really worth to buy Devo tune clutch over 3200 with street disk because it holds more than 3200 and shift better?

There are people are saying the twin plate will shift much better almost like stock car, other people are saying they say that because they had disengagment problem and we only need double or single washer under the pivot ball and longer salve which I just got from SBR.

Do I really have to pay 2200 USD for two devo tune clutch?
Or stay with street disk and 3200 ACT pressure, I just replaced them, I broke my tranny with 6 puck disk and 3200 so i removed the 6 puck and put the street disk.

I don't know what to do guys, I don't want to pay 2200 for my both cars and then burn the clutch after a while from driving my car at street and I might not need the twin plate for 600 wheel hp just because it shifts better and put less stress on my tranny.

I'm only moving to twin plate because it holds more and put less stress I don't want to break tranny stuff and heared it would shift better, is that true?

Please try to answer my questions, I know I'm fool, I searched alot and can't get the correct answer.

Any advice is acceptable
Thanks!

I have an exedy twin disk, I love it!!! peddle effort is like driving a honda civic the first time I drove my car I stalled it twice. Clutch comes with flywheel and everything. It was more on the expensive side but I mean youre getting a clutch and a flywheel. No chatter and it will hold up to 900 hp. The shop that installed mine has a race car that goes 9.40s and it uses the same clutch as in my car. I think its is 100% worth the extra money if you have a high horsepower car. Drivability is great since there's no pedal effort it's almost too light like I wish it had a stiffer feel because you could control the clutch a little better you really have to feel it.

I'm sick of driving stiff car pedal pressure, I want something very soft which even lady can drive it
Two things which I really hate, chatter and release bearing sound or the clutch plates noise before the diengagment or after the diengagment, I've seen cars with twin plate wich acts almost like the street act 2100 with street disk, no more pedal pressure, no chatter no noise, perfect drivebilly and will last almost like any street act disk and once it comes to shifts it's perfect and easy to drive even with power shifting and will hold more than 700 wheel hp in some skylines and sr20det.

I love my 3200 with street disk, I love the way it grips, no chatter normal pedal pressure, it will last for a while I'm sure more than any twin plate in driving the car at street, less price maybe buying two clutch 3200 pressure+two street disks+2 ACT or Fidanza flywheel and will cost almost the same price of one twin plate disk.

I don't want to buy something which will cost double the price and then slip it again.

Is there anyone would know how much hp should the 3200 street pressure would hold with street disk?

I know the 2900 with 6 puck will hold 595 TQ which is more than I need, does the 3200 with street disk holds that much TQ?

And how much should the Devo tune clutch hold?
I don't want to start breaking my tranny stuff just because using 6 puck disk with 3200 and I can't use the 3200 with 6 puck spring type because there is a guy who got a replacement for his disk and he still have problem and the fingers got mark on them because of the wrong design of ACT 6 puck spring type, the springs of the clutch were touching the fingers inside the clutch, this mean the springs are hitting they should make the springs smaller or change the whole design.

I broke my tranny because of using 3200 with 6 puck disk twice and you know guys how much would the tranny cost if you rebuild it!

So please try your best to help me out to stay with the street disk I have or to start getting devo tune twin disk plates and what are the side effect of getting the twin disks!

You need an automatic transmission. You've been fighting transmission and clutch problems for a long time. Maybe it's time to move on to something else.

I am running the same debate around in my head.
Get a 3200/street disk and fidanza flywheel or twin disk at twice the cost.
This car is going to be the death of me.

 

[shleppy]

Take it for what its worth, but I'm still very happy with my act 2900/slowboy 4000 disk combo. The pedal effort is around perfect-stiff enough to give some feedback but thats it. No disingagement problems, chatter etc. Since its a sprung six puck its alot easier on the tranny and only a little grabby when I slip the clutch out in first at low rpms(below 2000). I'm not making quite the power alqatan is, but seeing 56 lbs of airflow with 16 degrees of timing I imagine I'm making plenty. You can always run the 3200 with the slowboy 4000 disk. It'll hold the power, be easy on the tranny and cost less then the devo tune. You could also consider the hpf bronze sprung six puck since its rebuildable. Something like this would be in between the street disk combo and the twin disk. Personally I don't like the street disk idea because I think it'll hold at first, but get burned up much quicker then the devo or the sprung six puck and you want something that will last for awhile. With the devo clutch I've read of many people saying its really grabby and chatters alot, although some people love it and report no problems at all. I guess I didn't want to be one of those unhappy people 1200+ later.

By the time I bought my 3200 with 6 puck disk I thought ACT would be better than Fidanza, now I have ACt fkywheel with 3200 pressure on my both cars, removed the 6 puck disk from my Colt because I broke the tranny twice and still don't feel like kicking my Eclipse because the last time I broke the tranny was RPS 6 puck disk with 2900 pressure, so I'll remove the 6 puck disk and put street disk.

When i made my 10.2 run my video shows alot of slipping in 3rd gear so my driver had to shift to 4th gear very fast to stop the slipping, I had to replace the street disk with 2900 pressure from time to time like 4-5 disks, I still can't tell what hp I'll be doing with street disk I hope to reach almost like 600 wheel hp and 500 TQ with nitrous and low boost, my target is shoting more than boosting in my both cars, I know TQ which kills the clutchs.

I don't want putting harm clutch which will kill my tranny.
And I don't want to buy devo tune twin plate and it slips after a while because of driving my car at street, I would die after paying that much money

Is there anyone know how much HP is the 3200 with street disk would hold, and is it true the twin plate would shift better than single plate?

I still have RPS 6 puck spring type I might use it again with my 3200 pressure, I didn't have chatter either with 2900 but I feel affraid putting 6 puck disk even if it's with spring, I know it has less chatter and could be slipped and less effort in the tranny but I still love the street disk more than any 6 puck disk.

I wish I have way to let the clutch hold with 3200 and any other street disk, there are people started to report about having problem with the 6 puck spring type which ACT made for the 2nd time, I have 2 spare street and 2 6 puck none spirng and 2 6 puck spring type and was going to buy devo tune twin plate but after I heared people are getting problem with street I stoped this idea

I think I might return back to the rps 6 puck spring with 3200 if I slipped the street disk, hope I don't

Man my target isn't only getting better ET, there isn't any fun from driving an auto and you have all the fun once you drive the manual
