WHO KNOWS WHICH ONE IS BETTER FOR 600WHP CAR?
I had a lot of clutches. For example i have RPS TWIN C/C and destroyed it in 1000miles!!!
I dont want to make another mistake.
Advice PLEASE

 

I guess you would have to define "better" to answer more accurately. You are comparing apples with oranges. The Tilton is carbon on carbon while the Exedy is carbon on steel. The steel cannot take the heat that the carbon can. But then again the Exedy is larger to make up for it a bit. This makes it heavier which is probably better for street or drag, but not as desirable for road racing as the lighter Tilton would be. The Tilton is available in different clamp loads while the Exedy is not. Consequently you can get the Tilton to hold a lot of power by sacirificing clutch life (replace shims more often). The Exedy is pull type while the Tilton adapts to a push type system and requires a pedal stop. There is a price difference as well. Both are going to be a bit noisy, but should engage smoothly from what feedback I have heard. I don't know if that helps answer your question, but I think this is honest feedback.

*Warning: Shameless plug* Save yourself the confusion and get an ACT race clutch. 600hp should not be a problem. Heck, for that price, you can buy 6 of them.

 

This is coming from a supra owner that switched to Tilton ($4500) and puts down 1400rwhp.

Whaaaaattttt? Dude, don't scare me. I am in the hunt for a clutch soon, I was looking to buy a Carbon clutch because I heard they are basicly undestrutible and they can also be refitted/rebuilt once you wera them out. Now you come here and say that it only lasted you 1000miles?

You definately turned me 180 degrees as far is my hunt for carbon clutches. People please help us on this issue, I am lost too...



I have some feedback from a good friend though, there is a friend of mine his name is Trevor that runs his TT Stealth putting down 559whp on a Dynojet and runs 11.1@128, he has a HKS tripple disc clutch and he says that the hotter it gets the more that it grabs that also applies on the pressure, the harder you run it the harder it grabs, any thoughts?

 

Am looking at an ACT clutch for my Evo doing about 550 wheel horsepower and 510 ft/ib of wheel torque. Which pressure plate should I get?? At the same time I am using a 3200ib custom ACT pressure plate 6 puck clutch for my DSM style motor Evo 3, have just taken out the clutch as it was creeping at the drag timing lights on launch after running a few meetings with it. Its scoured all right but provided if the pressure plate's not warped, can I just reuse it with a brand new replacement disc??

 

That is another whole world with that Supra, I have seen that Supra ran at the local track and I also raced that same Supra once(I even have the timeslip). The clutch that this guys have is a much more custom clutch. That Supra has been a project for years.

I would ask his brother Eric at Apexmotorsports, he also owned 3 Supras Turbos in the past and being his brother he also knows exactly what to recommend.

By the way, do you guys know that Ryan also own a 600whp Evo?

Holly Molly, I just discovered something that gave me me chills, the WOTM Evo also runs RPS Carbo/Carbon clutch!!

The bad thing is that WOTM hardly take their car for a spin and it hardly or never have seen track times so it is hard to tell..

So man,you advice ACT single disk for 600whp? And how long will it last?

 

From what I have seen all the big runners use the Exedy Triple Carbon but Turbotrix uses the simple ACT. People say they always replace them but I dunno if that is false. But if it can truly hold that would be great...just wish I woulda tried it before cause I use the Cusco Twin cerametallic, and it chatters, holds great but I spent $1175 on it.

 

Yaroslav Listen up!
If you get the Tilton c/c clutch for your EVO you will never have to buy another clutch!
ALL the top racers either already use it or are moving towards getting one

Tilton is the hands down winner when it comes to clutches. Thier hydraulic setup alone is a big improvement over the slave cylinder to fork setup.

The Tilton twin will handle up to 1000WHP and I spoke to a guy from Exedy and was told for the big power thier clutch would not handle it and to talk to Tilton.

 

Turbotrix ran the same clutch all last year (as fast as 9.7 sec 1/4 mile), then switched to a stronger pressure plate early this year (I think). They are probably making more like 700+ hp, so 600 shouldn't be a problem. Yes a single plate clutch can hold the power and last a long time. It is probably not as "streetable" as the carbon (some chatter).

Driving style has a lot to do with it too. How do you think John Shepherd ran 8's with a street disc on his DSM which has a much smaller clutch? It is all about how he drives. I don't know of anyone else who could get away with it, so my hat is off to him. A race disc would have taken a lot more abuse and hold more power. But he didn't want to toast the DSM driveline so he insisted on the street setup. He would get that clutch to live for a long time too. Because we sponsor him he would swap parts out with new or rebuilt parts from us (usually a couple a year), but for the most part the ones we would get back were perfectly usable. Driving style is also why some people wear out the stock EVO clutch in 2000 miles and others in over 50,000 miles. It is not a matter of power, but driving style.

I am also realistic. Our clutch is probably not going to take the heat and abuse that the Tilton can, but it's not fragile by any means. You can't drive it like a slipper clutch and expect it to live (just like most clutches). I think we offer great value, and great performance for most applications with our product. I don't think ACT is the right clutch for everyone, just like I don't think the Tilton is the right clutch for everyone.

 

I say do the tilton twin cc over the exidy tripple carbon. I think they are both in the 3500 range

 

Very well put ACTman.

 

I still would never pay 3500 for a clutch that is waaaayyyyy To much. Id Stick with a single six puck.


Dont forget Look at what you asking!

when you mod, expect to have some change in drivability, you cant expect a 600 awhp Evo to drive like it was stock.

 

this statement is not even remotely true. do some research about the instances of slave failure on the tiltons. the failure happens inside the bell housing which means the trans has to come off to fix the slave. how do i know? because i've personally seen it happen three times. we had dnf's the first stage of pro rally events because of the tilton. putting the slave inside the trans is risky to say the least. the exedy design has plenty of holding power. hell i've seen the stock clutch go 12's dozens of times with the right driver. you can destroy any clutch if you don't know how to drive.
