I understand exactly what you are saying and it was news to me as well. However after talking to Carey @ ERP for several weeks about my issue, and then shipping it off the RPS (the guys who actually make the carbon) and me talking to Rob (the owner of ERP) that was one of the things that Rob mentioned.

I realize that lots of guys slip (i follow Steves launching post) however I was simply commenting on what I was told by someone who is part of the assembly/production of the clutch. You will notice I also said "daily driving" as I know there are several guys who slip the clutch to launch it so I made the assumption that is what Rob was referring too. Im no specialist, just after talking to damn near everyone at ERP and RPS about my issue, I figure I should take as much advice as possible to play it safe.

I was sold on the same thing. Maybe the "instructions for use" change after you install the clutch.


I would guess that the manufacture would want the least amount of abuse possible giving the product a reliable name.?


I see a few guys with over 1000WHP using this setup and I am sure they beat the hell out it.

 

I used the Evoms conversion with the updated bracket.

 

Steve, How's the clutch holding up? When you start from a light do you find yourself, slightly slipping the clutch to make it a smoother engagement?


That may have been a very stupid question, not by the question but rather who the question was asked to.

 

the clutch feels the same as it did 20k miles ago.
when Tim comes back from the texas mile and the pocono races, im hoping to remove my numeric racing shifter cables and go back to stock. (the noise is absolutely unbearable) We're going to take a look at the clutch discs to see how theyve held up thus far. (Tim thinks all 3 discs will look fine, 90%+).

Elite, remember, i have gt2 gears... my first gear is a 3.15 whereas 997tt is 3.82.... so i have to slip it (ride it) a bit more than normal in order to have a smooth engagement...
lets say im at a stop light and im ready to move.. i slowly release the clutch pedal and then apply throttle (1500-1800rpm) and continue riding the clutch until the car is moving quicker than it would at idle (~6mph i think). the quicker you want to get off the clutch pedal, the more rpm you need to give. if youre driving it like a standard sachs 2.5 and give 1100 rpms to come out of a stop, the car will bog.

slip slip slip that clutch ! the more you slip it, the easier youre being on everything else like motor mounts, tranny mount, gears, bushings etc

you just gotta keep telling yourself that the clutch is designed to be slipped and that youre not doing any damage to it whatsoever. on flashed stock vtg we're making ~500 torque to the wheels right ? so each clutch is dealing with about 160 lbs of torque. lol thats why they'll last forever. each carbon disc is rated for 400lbs of torque. so slip away.

 

Love it Steve. Tim has put this clutch to the test for sure!


You have explained the condition of my clutch release to a "T." I feel a little bit more comfortable with my technique since you have the GT2 gear setup. I do the same with my stock setup. I guess I am playing with it at this point.


Didn't mean to use you as an example but, I knew you would be the extreme example for reference on the clutch.


Please let the thread know on your findings. We all are probably wondering on the reason for replacement disc that ERP sells.

 

I noticed that last few times I have driven the car, hard to explain, "Squeak in the clutch pedal.?) I can feel it but, I cant hear it.


Clutch now feels on the rough side now during engagement only.? I am not sure if I need to do the 2nd gear start and cool process to help seat the plates.


Any thoughts on this?

 

Clutch is Grabbing better now that I haven't really driven the car on the street.


Clutch was really rough in reverse. Long trips to the track in the same gear prior the beating of the clutch has worked out well at the track.

This clutch performs well on the track and not very well on the street due to its difficult engagement in first gear with street duty. Once the car is moving the clutch is effortless to shift with little clutch movement. I tend to have to slip the clutch to leave a stop light (not in a race), while most say that this clutch can be destroyed by moving the car to a trailer.


I actually like the high engagement point with the GT2 slave conversion that I did with this replacement at the track but, let someone else drive the car and soon find out, that this is not normal.


Today, If I drove this car every day, I would choose a clutch that I would need to replace every 30K over something that would never need replacement. On the street, this clutch did take the fun out of the car in my opinion.


A buddy of mine did the sachs conversion (Pressure plates) and I believe that this is the way to go. His decision and recommendation has always cost me at least $300 when I choose not to listen.
