So I've owned an evo for the last 6 years...since '01, an E7

Went through lots of clutches. My car had about 450whp.

-ACT - Absolute trouble. Would work great in the beginning, then lock me out of gears after

-HKS GD MAX- Same story..worked great for about 6 months, held up to high rpm launches. But after 6 months...the bolts on the clutch snapped. Rebuilt it and after 3 months ended up with the same problem.

- RPS twin carbon- Seemed great. Held up to even more high rpm launches but then one day something went wrong and the clutch pedal was on the floor and wouldn't come back up. They sent the replacement parts free of charge(great customer service though) and it was repaired.

My car was sold earlier this year.


Now I'm on to evo 7 #2
Totally different build designed to net over 650awhp and be daily driven(probably not daily but 3-4 times/week)
In all the years being an evom member I'm convinced that there is no more research I can do.

I would like people who have 600whp evos to comment.

I have made up my mind not to be 'cheap' this time and will spend the money, but expect great quality, service and customer service etc.

After weeks of more research I've ended up with these for options:

(1) ATS(carbonetics?)- triple plate carbon
(2) Tilton- twin carbon. Good I'm sure but read that ppl say don't daily drive it as the carbon wears wayy to quickly?
(3) Exedy triple- just because shops like ams, buschur stand by it.


Now...my problem with the first 2 is that they are push. Exedy is pull type.
What's the use of going push type when ams or buschur don't see the need to.
Is there a disadvantage to it that they are avoiding?

So 600+whp guys...Im sure you all have spent the same time researching these products as well as some of you have tried the different options as I have and have either been satisfied or been to hell...

what do you suggest?!

 

We are actually running a push style conversion of the Exedy Triple Carbon.

If you aren't a super balistic shifter, I would go with the Exedy Triple. If you tend to shift very hard, fast, and high rpm, you may experience release clip issues. If thats the case, we are still in the process of working out details of releasing the push style Exedy clutchs.

 

IIRC Buschur also runs the Tilton in one of his cars. It also sounds like you're pretty hard on clutches too.

 

I do shift very fast and hard, but as for rpm this motor is the ams 2.3RR so shifting would occur at no more than 8900rpms as they recommend.
So in your opinion it would seem like a push type would be better suited? correct?

 

I am...
thing is back in the day these clutches I used never got a break.
On a good day at the strip I would put down a minimum of 10 passes and sometimes 5-6 of these would be back to back passes.

Was really hard on the clutches. But if it means that after each run I will have to let it cool down...I also have no problem with that.

Much easier than having the car towed and then having to pull down the g'box!

Thanks for the replies....I know they'll be slow but keep them coming.

 

The Tilton CARBON usually wears quickly, but remember, they also make a cerametalic version and a cera/organic.....

But for what you are doing with it, I would say go for the ATS. its cost effective and as long as you heat it up properly, you should be fine.

I daily drove my Evo 8, and had the cusco carbon two disk (very close to the exedy two disk) and it lasted for 60k miles or more.....not as many passes on it as yours, by a long shot-but still, it lasted.

 

bump

 

get the exedy triple plate cerametallic (get the carbon if your BIG into drag racing). I love mine. There are 2 different kinds of pressure plates you can go with on this clutch. One has a heavier duty pressure plate than the other. I got mine from chris@nolimitmotors. He did pretty good pricing compared to other places I've seen

 

thanks bro will definitely consider since my setup will be similar to yours..

just using a 37R instead!

 

which clutch are you gonna go with? I'm curious

 

well after I got tired reading ..realized that there were three choices which were:
-Exedy triple carbon
-ATS triple carbon
-Tilton twin carbon

I ended up purchasing an ATS triple carbon(push type)

realized that many high hp cars were opting for push types..which were only available from ATS and Tilton at the moment AFAIK

and the other's that were using exedy triple carbon were converting them to push as 'gsnt' said above.

Other than that, my friend's supra puts out over 800rwhp and he is using an ATS triple carbon with great results. And that car gets hammered!

The reason for not going tilton was simply because not many people were using them as yet..in order to get some solid reviews.....besides David Buschur of course.

My car won't be complete til maybe January or so since I'm buying all the parts and installing all at once. I'll definitely write a review when it's done.

 

whats the advantage of a push type clutch??? able to do faster shifting or something???

 

^there's some threads around explaining it...

but for me the major factor is the center clip.
Too many times I've had my clutches give up on me because the center ring/clip on the cover snapped!

With a push type it supposed to reduce the chance of this happening

 

are you talking about the retaining clip and the ring in the pressure plate that attaches it to the throw out bearing???

 

^yeah supposed to be it.

I've destroyed that on every clutch I've owned

plus know about numerous incidents where people experienced the same
