I was told by the Carbonetics rep that even if you do glaze this disc that it'll return to normal after a bit of normal driving. Sucks to hear about the warping of the twin discs. Glad I didn't go that route.

 

This thread is relevant to my interests. What are some vendors that sell this?

 

this is not true at all. this single will warp pressure plate faster than twin will. and it simply will not be good drag clutch.

 

I just had mine apart, very thick pressure plate, no warpage on mine and it doesn't look like it will, whole clutch looks mint even at 600whp on MD. I 100% agree that it's not a drag clutch which is OK with me as my car is not a drag car. Holds 30 psi on a 2.3 and BB Black on the highway perfectly to any speed.

 

Well i am going to drag race the hell out of this clutch with around 450 mustang tq... I will post my experiences.

 

Good luck with that! If you don't launch it and roll it out and then not shift hard it will be fine as is, mine still went 10.7 like that.

 

My understanding is that when used in a drag race application is to heat the pressure plate and disc with a few light clutch engagements prior to launch. In theory this should help in regards to warping. Obviously there is no one size fits all clutch. In order for a clutch to hold gobs of torque there will be a trade off with drivability. We can't have our cake and eat it to unfortunately.

 

Contact Billy at Vivid Racing. He can set you up with the clutch.

On a side note, I'll be doing a full write up of my Carbonetics clutch, Vivid Racing and Competition Associates in about two weeks.

 

This is true, at the end of the day there is no ideal perfect clutch for the EVO yet, you end up with a stiff pedal, a noisy clutch is embarassing to drive, a clip that pops and leaves you stranded, a slipping clutch or a clutch that blocks at high RPM or all of the above.

 

I am not going to go easy on it or roll it out. i am going to throw everything i threw at my twin disc at this clutch. I cant see how it could be any worse then the Exedy. I toasted that in one day at the track. this clutch has less pieces that will warp and less dics that will be hanging up. not to mention the fact that that carbon disc should hold up to the heat better. I hope i am not getting my hopes up.

 

Hate to say it but it will slip all the way down the track, I ran a 12.67@85 launching it and 29psi, 10.7@137 no launch and slow shifting at 23 psi.

 

Why is it magically going to slip down the entire track? carbonetics says it can hold this tq. Ive got my launch map around 15lbs, are you saying its going to slip at the line? This would make the clutch worse then an old ACT i first had on the car?

 

Curt, you have to understand not many can drive like you. This includes excellent clutch modulation on the line.

Quite simply "TQ holding" and "launching capability" or two different things. For AWD car to hold 400tq from dyno run the clutch needs to hold about 550tq to drag with that 400tq.

But aside from that this clutch wasnt designed to be drag race clutch. the spring center will self destruct for most drivers. its just not designed to take that load. My opinion is even Curt has been just lucky with it so far.

I have this clutch as well. not the pro version. I have mine mated to stock fly and ACT 3200. My only complaint so far is pedal is stiffer than i want. I am sourcing parts now to convert to billet pressure plate. The billet plate holds more but has easier pedal. Plus it gets rid of pull setup.

Its a good clutch. It just needs to be used as the designer intended it. I would term it "very delicate" for drag use. Much like dragging on a stock clutch. IE most will kill it trying to hit high 12s. "exceptional driver" will muster mid 11s without killing it.

 

Exactly good point, absolutly not a drag clutch, so for me it's the best clutch ive used since I really don't drag race this car, if I wanted to drag race I would have bought a real car and ran 7's and saved $40,000 Not impressed by a car than runs 9.0 anymore.

This clutch system when used with an EVO as an EVO was intended to be used for(a proper do it all road car) is still the best out there.

 

I would agree with some of what you've said but if we are going to talk about how well this clutch is working in drag race application I would be much more concerned with 60ft times. Obviously 10's are possible with this clutch and it's handled quite a few launches in my car and I should be mid 11's with the power I'm currently making. Time will tell with more people using it. I won't make it out to the track for another month or so. I'll be sure to report back how it held up.
