Thank you.

 

Thanks for sharing. To me it really is like you say: it takes the fun out of driving the car on the street.

For the race guys it probably still is one of the best you can get.

 

There is a clutch master cylinder mod being worked on that will give you pedal adjustment. You will be able to lower the engagement point and travel ratio.

 

first in line!!!!!

 

Second!

 

Testbed!

Going to market or is it a modification?

 

So there is probably a fix for a problem that doesn't exist? Cool.

Kidding aside: nice if this works, but almost every single statement about this clutch has been proven wrong here with my sample (noise level, chatter, engament, smoothness, judder). I start believing again when I ride a car that has all this fixed.

A guy here is testing a Clutchmaster 850 currently. Rattles like a Ducati in neutral on idle, but everything else is like stock. I don't know how much Nm it really holds, but it is no nightmare to start with. He will test it soon on the dyno.

With my clutch or others I have installed I have not experience what you have experienced. I really have to question the install. Sounds like a bent floater or the plates installed in the wrong order. I have not personally seen either of those two instances myself but I have heard stories. It is very easy to bend one ear of the second floater installing the p plate/cover or installing the plates. If done wrong it will let the psi plate push the second floater plate against the starter ring instead of the disc. The plates where marked with orange dots then stickers and some may not have been marked at all.

 

Anything is possible, but I doubt it. I will check the clutch when I pickup the car next week and check for bent parts and evenness of the plates.

When I bought the clutch it was still some months before the engine build, so I put it aside. Shortly before the installation I asked ERP if this clutch is going to hold the torque I expect because I got notification to verify what I got.

They looked at the internals and decided to exchange them - just in case. Free of charge - a great service.

We took apart the "old" clutch parts and put them on the desk in their order and put the new parts back in. No mistake there. Installation in order of what we got delivered. No mistake there.

The new parts have a stronger power tansmission part - not sure what the correct english term is. It is beefier, rounded. See attached pictures.

 

Before:

 

The ERP clutch is out and I have new one in:

Drives like OEM, has a mid pedal engagement point, smooth as it can be. It is proven to hold 1200 Nm (885 ft lb) and good for 1400 Nm (1032 ft lb).

I will tell you what it is when my car was on the dyno and when I have some real figures to show.

I can move the car in traffic without thinking about it. Even with idle rev a 10 out of 10.

Chatter is there as well, because it has a LWFW as well, but it is much less than with the ERP.

I will now check the ERP clutch for damages or bent parts. Have sent the carbonclutch.com guys an email with my complaints and a link to this thread. No reply yet. We will see how that one will end.

Good luck I was planning on going with an ERP when I upgrade my clutch from the Sachs 2.5 but now I'm seriously questioning that after reading this.

 

Well with the nearly daily if not more updates of bashing the product there is no updates about if it was damaged or not.

 

Tim, I am not bashing the product. I was describing what my experience was. I have contacted the seller and got no reply within a week - I cannot update here if the seller doesn't backup his product.

I repeated my request and put ERP in CC and I they are asking me to send the clutch for looking over it. The clutch will be sent to them now and you will get your answer.

I have nothing to hide. Finally it is my money that was spent and I didn't get what you and others got. In addition to that I find it interesting that I am not alone with my experience. Are these damaged clutches and wrong installs, too?
