The stock clutch is easiest on the TC and most streetable while a carbon/carbon Tilton triple disc is probably best for continuous launches. Doesn't help much, does it? Of course we are talking two extreme opposites.

Seriously though, the driver has more affect on the TC than the clutch. If you are expecting the clutch to save your driveline, leave the restrictor in and don't go overkill on your choice of clutches. If you can take responsibility for the driveline by careful driving style, you can get more aggressive with clutch choice.

Maybe this is a little oversimplified, but you get the idea. I could go on here and tell you how great our clutch is, blah, blah, blah... but that's not cool. It's more important that people know not to expect miracles from the clutch to make up for bad driving. Same message goes for expected clutch life. Some people just know how to make things work and others just have a knack for destroying parts.

 

Great response. theres things on here that I read and dont totally understand (like If I buy said clutch will my TC have a higher percentage of breakdown than If I had boughten a different one) and when I read these things it makes me worry, but now that I understand that Driver carrys more weight in saving of the TC than the Clutch, is there a reason that my clutch only lasted 5 hard launches?

and with your ACT HDSS setup what would someone like me (minor slipping clutch at 10k miles and 5 hard launches) expect?

thanks again for all your expertise,

 

I responded to your email. Thanks for inquiring.

 

From my experience, the best clutch I've ever driven on an Evo was a quartermaster clutch. Check out www.devotuning.com for more information. The clutch pedal pressure is actually less than the gas pedal! It has a great feel, and you can rip through gears like nobody's business. It can also hold all the power you can make. As far as the ACT clutch, I used to like it, until it's disengagement habits singlehandedly ruined my friend's transmission, and refused to replace the clutch. Exedy clutches are pretty good from my experience. The only problem is the Carbon one is the only one that seems to hold decent power, and you have to heat it up to make it grip.

Overall, despite it's absence from this poll, QUARTERMASTER twin disc clutches are the way to go for me. Once again, check out www.devotuning.com for more information.

 

ACTMAN. I havent receiced it should I call? or can u send another did u send it to alstotter@aol.com ?

 

OK, I forwarded it to that email address. Let me know if you got it.

 

no luck wonder if aol trashed it, spam folder isnt available , wonder whats up.

 

You dont have to heat the RPS carbon unit, The Evo I have it on makes 528ftlb and this holds it every time no problems, You cant go wrong with this Clutch.

That's strange. Below is the message I tried to send in response to your email. Sorry to polute the thread everyone

Aaron,

Unless you are planning some serious upgrades, our HDSS well perform nicely. Personally I would remove the restrictor, especially if going to the track, but I don’t mind taking the responsibility of broken parts. Our clutch uses a premium organic facing that puts up with abuse pretty well. It is not indestructible, but I think it is a good compromise. I mean, our competitors Kevlar may last forever if is not overheated but then it doesn’t respond well to heat and the coefficient of friction is much lower than the stock disc which means you have to make up for it with even more clamp load.

As far as negative affects on the TC, well that depends a lot on you. Yes, the clutch will transfer more power, but it not harsh by any means. I am not going to blow smoke at you… How you use that power is the key no matter what clutch you use.

Flywheels - I just copied this from another message I wrote to someone this morning: I am not a big fan of aluminum flywheels, but the Fidanza is probably the best manufacturer of them. We obviously prefer the Chrome-moly one piece flywheels. Unfortunately we won’t have one for quite a few months. Road Race Engineering has a good looking flywheel but I don’t know the details about material, heat treating, gear profile, etc so I don’t know if I should recommend them or not. The potential problems with the aluminum flywheels are primarily with the friction surface, sometimes called the heat shield. Even brand new they aren’t perfectly flat. If you get the clutch real hot, they warp and rise between the bolts. This affects clutch disengagement. Aluminum also has a harder time staying on the end of the crankshaft. I don’t want to sound all doom and gloom though. Many use them with no problems at all. The stock flywheel is a forged piece (or at least ductile) which is only 14 ½ lbs.

 

this thread is far from dead son

 

I went with the ACT due to price. But I also consider the Exedy.

 

Dont waste your time or money on ANYTHING BUT EXEDY. They make the best product hands down, look at their reputation and longevity.

 

ACT make a great product. I love my ACT street clutch.

 

So far there appears to have been FAR more EXEDY clutch failures on EVOs than ACT failures. Take that for what it is worth... I don't have either yet and although I am still shopping, I'm leaning toward the ACT.

 

I don't know all about failures and so. But I know that I love my ACT clutch.
