So if a twin disc is a no-go, what's a cheap, safe to the TC alternative? I don't want something as strong as a carbon so that my TC stays intact...man, I was really looking forward to a twin disc...is it best to just get a slightly stronger single disc then like ACT or Exedy's singles?

I do not know what you do Sean. My reply is to LogicPerformance, who, is in fact - a retailer.

The Exedy clutch is suitable for drag, ciruit and street driving - AMS is running Low 10 seconds with it... Al at DynoFlash is running low 10 seconds with it.

The Ferrari F1 team used an Exedy in their car as well.

If you are having a problem - have you taken the time to contact Exedy? Have you sent the clutch in for inspection? Wht proactive role have you taken besides posting on the internet?

Exedy is a *very* professional company to deal with and tries to appease all customers, especially the Evo community.

Take the time and call Exedy tomorrow and go to the horses mouth with your problem... don't go to the otherside for some bullsh1t.

Matt do you know who sean is? If he builds his evo like he built his talon the twinplate is sure gonna blow out. Hes hardcore. Chris at AMS right now has blown out 2 twin plates and is waiting for a 3rd clutch to put in from what I've heard. And just because it's in 10 second cars doesnt make it right for drag racing. I believe al has a carbon one installed. You reading this Al? Post your thoughts. And gold how do you know its bullsh*t? Have you ran one in your car?

All depends on your driving style and your HP #'s you make. Exedy is coming out with somthing new here shortly from what were told.

So what stops the heat transfer? BTW I've seen a twin plate clutch warp the center piece then shear all the bolts off of the clutch cutting the case on the trans what about that heat transfer?

Chris

The heat that isn't absorbed by Exedy's High Quality Grade Carbon Material would be transfered to the intermediate plates and the flyhweel.

As for knocking the Exedy or not - this is just all very ironic that your post highlights ONLY the benefits of the RPS and gives no information about any OTHER twin plates... directing all negative research towards Exedy, without testing the RPS under the same conditions is very biased... thus IMO, knocking the product.

The Exedy is attempting to attain a few goals... one is power capacity, the other is streetability the third is longer life. Based on Exedy's testing, Carbon/Carbon life is half that of a Carbon-Metallic clutch. Exedy Japan also makes a TRUE Carbon/Cabon but does not import it into the US due to the Tilton patent on the technology.

Being objective here, various manufactures have various focuses.

If the consumer is looking for a heavy, bulky and primative clutch that may hold te power and be a chore to drive on the street - then by all means the RPS is the way to go.

However, if the consumer want a light, streetable and high tech clutch, then Exedy, Tilton or AP Racing is the way to go. However, when you factor in price and availbilty Exedy is the *only* option.

But to each their own - I would have felt better seeing a more "level playing field" when you guys decided to do your "research" on Twin Discs... a more appropriate title for this post would have been Exedy vs. RPS...

Chris hasn't worked at AMS in over 8 months (maybe a year now)... If you're talking about Martin and the AMS shop car, they had a Twin and outgrew it, they now have a Triple and have made many passes on it without a problem.

Maybe Martin would chime in on his experiences with the Exedy. Or maybe Al can comment on if it's held up or not?

My information is comming from engineers from Exedy - not a company trying to sell a clutch.

Again, I have no problems with you guys selling an RPS... it's just a very biased post with no clear objective analysis...

For some facts from Exedy on Carbon Clutches... Check out this link <Exedy Carbon Clutches> .

This is developed by the engineers and R&D department at Exedy Japan.

However, keep in mind that you need to buy whatever is suitable for your application and expectations. All this is, is information for you (the consumer) to make an educated decision. This is NOT a shot at *any* clutch manufacturer or retailer.

Some people love ACT and swear by it - that is fine, it fits their needs. But no reason to rag on a manufacture just to sell another product.

That seems to be the problem from what I've seen. Why not make a material that absorbs it and does not cause it to warp?

People know the benefits already of exedy thats why they bought one. Ryan at RNR runs the CC clutch and he says it works great and his car is over 600whp. A twin plate would last 7 passes at that HP from what I can tell from sean's experiences.

The Exedy is attempting to attain a few goals... one is power capacity, the other is streetability the third is longer life. Based on Exedy's testing, Carbon/Carbon life is half that of a Carbon-Metallic clutch. Exedy Japan also makes a TRUE Carbon/Cabon but does not import it into the US due to the Tilton patent on the technology.
7 passes at 400hp is not long life I know its a normal twin but honestly how many passes before the warpage occurs in a carbon? Carbon has to heat up before it grabs better causing even more heat.


If the consumer is looking for a heavy, bulky and primative
29lbs 12.5oz vs 28lb 8oz for exedy? Dont see weight being an issue.

clutch that may hold te power and be a chore to drive on the street - then by all means the RPS is the way to go.
From the reviews I've read on evoM people say it drives like a stock clutch and the guys wife can drive it with no problems.

However, if the consumer want a light, streetable and high tech clutch, then Exedy, Tilton or AP Racing is the way to go. However, when you factor in price and availbilty Exedy is the *only* option.
I dont work for either company so I sell what works good and makes the customers happy. If it makes them happy to by an exedy I sell it to them. But I recommend the BEST product for the money and longevity.

But to each their own - I would have felt better seeing a more "level playing field" when you guys decided to do your "research" on Twin Discs... a more appropriate title for this post would have been Exedy vs. RPS...
Who else makes a twin disc pull type clutch for evo?

Hopefully martin will come on here I want both sides to post on here. How many passes does AMS have on there Triple plate, How does it feel now? Is it an on off feel? Yes its biased but tword working clutches that don't break. And everything you post is biased tword exedy for obvious reasons. Tell the engineers that give you your information to fix the problem in there clutch then we wouldn't even have this problem or debating the clutch market at all.

This is what my concern is over. After reading the initial post, UT has formed an opinion that twin discs are "no-go"s... In other words a bad clutch for the evo.

This is by NO MEANS what anyone believes, ESPECIALLY for a car "slighty over stock"... I don't even think that's what you guys planned to try and get across. But when you provide a lopsided view, people will form misled opinions.

Exedy for the record has three variations of their single disc, three various twin plates and three triples as well ... truely something for any power level.


UT - When you make your decision, ask around and get opinions from MANY users.

For your driving it would work great for you it sounds you would never need an RPS clutch. An exedy single or twin would give you enough holding power. Once you put high HP to the clutch is when they are causing the warpage.

Don't worry hopefully (crossing fingers) I won't be making a decision any time soon, and it will be VERY VERY researched...I was mainly trying to get Talon to suggest his alternatives, cuz I've heard from MANY people that the stronger clutches end up ripping the TCs to shreads and that's why the stock one is fairly weak, and a clutch is a lot cheaper to replace than a TC...I'm still leaning towards an Exedy Twin, so no worries Matt...and it's just leaning, so no worries Talon

Edit: after reading Talon's last post, thank you both for the advice, and sorry for semi-hijacking the thread...I get it now

Like I said UT, I sell both so when you need one call me up. Its just that 96% of drivers that use a twin plate don't need anymore holding power than that its the 4% out there that need the clutch that holds power like this.
