Just parked my car for the winter. Next year looking to do bigger and better things. I'm starting my parts list, and one thing is a clutch.

This year I made 560whp and 405ft. The motor is an 84mm darton sleeves gsr. Turbo is a pte5858 on 20psi. Next year I'm looking to up the boost and max out the turbo. Earlier this year due to oil pressure issues I had to pull the motor. I have a CC stage 5 clutch and CC 12lb flywheel. Took the clutch off and the disc was missing chunks (never slipped once). So I decided to put in the CC 6 puck and see how that would hold. Didn't slip all year. Don't have the motor apart so condition is unknown.

I know 98.6% of people on here are going to say get a twin disc. Yes I know...I get it. A buddy of mine has a CC twin disc and all he has had is problems. I want to know who here is making more power and torque than me with a SINGLE DISC. What are you using? How do you like it? How does it perform.

I'll be running the 235/60 M&H race masters and a gsr trans. Any intel would be nice. Here's a couple of pictures of the car/setup. And my old 4 puck.

I'm running a CC stage 5 as well, so far its lasted me a full season of daily driving(hard), 3 dyno sessions, a day at the track...etc so far so good but that was at 450whp. I just retuned and I'm making 727whp and 498tq and everyone is telling me the same thing twin disc twin disc twin disc but i hate how that **** rattles and squeaks, its not ideal for the street i like my single but i know its on its last breath. I'd like to know what some other options would be as well.

This the second thread Ive seen recently about the CC Stg5 that broke apart like this.

Im running the Clutch Masters FX400, sprung 4 puck without issues (597hp peak/380ftlbs peak). Ive had this clutch for over 5 years now, 10k miles, many many track hits and dyno pulls. I love it. However I think its time for me to upgrade bc I dont think it will hold up to slicks. I've only run DRs so far.

*Would it be a fair statement to say the CC stage 5 is equal to the CM FX400? Both sprung 4 puck ceramic.

I'll be grabbing up a Maxx Extreme ACT 6 puck (rated at 485ft-lbs) for next year. The current XTG6 has held up but its starting to get stuck at high rpm in 4th gear at full power. The actual pressure plate is about 5 years old so its about time. But I wanna push the turbo next year so I expect 450+ ft-lbs.

BTW I think the clutch chunking is normal. Thats how my ACT disk of 4+ years looked as well.

X2 I have seen a couple myself and called CC and they said it was oil contamination which I know isn’t the cause my motors never leak a drop and I use gloves and brake kleen during install. One was a all motor car only making 250 torque they sent me a replacment and it did the same thing.

My CC stage 5 unsprung held very well for me BUT it came apart. I pulled my engine out due to Spiroclip failure and when removed clutch the pads were just about all destroyed. this clutch has 4000 miles on it, no dyno time and about 25 passes at the track at 450whp.

Im going with a clutch masters stage 5 this time around and 550-600whp. I dont have twin disc money right now with having to rebuild my motor. I've run CM in the past fx400 and really like it. clutch held up well at 400whp in my old LS hatchback car.

the thing with these puck clutches and high HP they dont hold up to the preloading is what im gathering. I believe less preloading would allow the disc to last much longer than it did for me but I also dont want to destroy my transmission. I will be doing less preloading this next time around and see what the outcome is.

Turbo-LS - Im very interested to hear how you like the FX500 when you get it back together. Thats my most likely upgrade path as well.

These builds making near 600 horsepower or more than 600 horsepower are really just on borrowed time... at that power and torque level for reliabilities sake you really need to run a twin plate

shawty22

I was looking at the Act Maxx Extreme clutch too. I've heard it holds up well but it has a very harsh engagement. Anyone ever try that one out?

I'm looking to hopefully make 630-650whp and 450ft-ish with the 5858. I would of went higher this year but a single 255 and pte1000s can only supply so much fuel. Lol I drive my car 99% on the street. I brake boost, preload, just beat the living hell out of it. Built it to have fun so that's what I do

the ACT maxx extreme plate is rediculous very hard engagement and not drivetrain friendly.

shawty22

Sounds fantastic. What is the fx500 suppose to hold up to?

Turbo-LS

iTrader: (4)

the FX500 is supposed to hold 600whp

If i could afford a twin disc its the way i would personally go but can't right now. The future ill be upgrading.

shawty22

I wonder what there torque rating is. I would like to hear some expieriences with the fx500. Because that looks like they only come in a unsprung 4 or 6 puck. So I'm wondering if that would just be as harsh of an engagement as the act with a sprung 4-6 puck. The fx500 is also quite cheaper.

I was running a COMP unsprung 4 puck, engagement wasnt bad at all

LightningTeg

Saying its rated to 600whp doesnt tell me anything. 600whp revving to 10k and making 300ft-lbs or revving to 8k and making 450ft-lbs are 2 different beasts.

Turbo-LS

iTrader: (4)

i believe the torque rating is 400-450

shawty22

I can't find a torque rating to save my life. All it says is racing clutch only, not for street driven cars, unsprung 4 or 6 puck, blah blah blah. A fx500 for a Mini Cooper holds 200-400% more torque. Haha. If that tells us anything what to expect to see on a Honda...?

Muckman

iTrader: (2)

That is a huge irritation of mine too. Why cant they just list the torque its rated to hold? Percentages are too wishy washy. Is that supposed to be % of stock torque which is rated at the flywheel or at the wheels since thats how tuned cars are measured? And I think that percentage value is ON TOP of the stock torque bc some of the lower clutches are reated at 100% of stock torque which would be the exact same amount as stock. So I have to assume they really meant 200%. And some even rate in HP. Its just ******* ridiculous

shawty22

For that Mini Cooper it said rated for 415ft. Lol on T1s website it says 200-400% for a b series also. What is the stock gsr torque to the flywheel? Like 120-130ft?

LightningTeg

That tells me they havent really tested it. At least with ACT's you know exactly what your getting. And when they say 150% is that 1.5 X stock torque or 2.5 x stock torque ?

Edit: You guys beat me too it lol

Muckman

iTrader: (2)

~128ft-lbs peak at flywheel
~110ft-lbs peak at wheels


So 200%-400% = between 330ft-lbs and 550ft-lbs at the wheels? Yeah thats nice and vague.

Lightning - It has to be % increase PLUS stock bc some of the clutches are rated at 100% which if it was equal to stock torque would be retarded. lol
But this is my argument. Just list the damn rating. Customers shouldnt have to guess and assume.

shawty22

Sounds like its a total hit or miss with the fx500. But if it actually would hold 500-550ft, that would be really impressive. Specially for roughly 200 dollars less than the Act. So...someone should try it out by next spring and let me know. Deal? Lol

LightningTeg

A quick search revealed one useful thread, but the only input was that the clutch could only hold up to 350ft-lbs or so.

I'VE had the act pad chipping problem in the past never slipped tho, on a 4puck unsprung with heavy duty pp act,,,,, recently I pulled apart my motor that was running the extra extreme pp with 4puck unsprung. And there is no chipping at all on any pads,, was making anywhere from 350-500hp 275-375tq that's depending on boost,,, I was wondering if act might have changed something on the pads to help prevent this?? Or mayb I'm just lucky on this disc,,

my fx400 held 350ftlbs so i woudl imagine the fx500 will hold more
