I have had a UMW clutch on my car for 3 years or so now. I've had a few DE days, and love my car. I had similar issues and got the Evoms slave mod....and recently re-mod as they upgraded the hydraulic line from rubber to braided stainless...

Black pentosin is not a good thing.

I think the product that I have is great. There are so many issues in this thread that I think it is important to keep it to the mechanicals and not to the marketing of the stuff....Enrique has done some track. I can say that it does great there.

So, I don't think it is fair to attack Kevin, non sponsor or not....


Anyway, my 2c. I am a big fan of f1crazy's adventures, but I suspect the real issues are a complex mix of things...and the slave/accumulator on these cars sucks. Kevin's clutch is way stronger than the stock one, and enrique is a great driver, so I suspect the issue lies elsewhere...and that issue may have caused problems for the clutch.

I don't let anyone drive my car except my mechanic after fixing all the junk....just too expensive to let it go.....there is so much power that one moron/abuser could total much of the clutch....I suppose poor heel/toe could be a big issue too....etc. I use two feet in my driving style.....some use one....meaning I brake with the right foot.

I re-read Enriques post. It doesn't seem as though he is actually BLAMING UMW. It seems he is asking if anyone ELSE has exhibited HIS symptoms, so he has a direction to go. I think in hindsight, the ONLY direction to go, is to pull the tranny and see what's doin...

Although I'm still infuriated by the 150 track miles = 12,000 street miles, the car needs to be diagnosed properly before drawing a conclusion.

I have a UMW clutch and spend every weekend flooring it in second gear
from 2000 rpm till 5000 rpm, and lots of torque and lots of boost. This is
my third clutch. The stock one went away very quickly after this sort
of driving with a generic 1bar flash. The stage II EVO Sachs clutch went
away soon after getting a UMW race gas 1.4 bar flash and refurbished
wastegates.

You also told me that you had issues when you first pulled the car out of the dealership > your words were, I thought that it was related to the new 997 shifter. You did not go back to the dealer to get this looked at.

I was told it was the shifter when i called the first time about a year ago Kevin. Why would i notify you, if I was told it was something else, that had nothing to do with your part.

As we fast forward to this issue, you mentioned that you already had the car to the dealer and the dealer tech told you that HE feels that the clutch disk is HANGING on the mainshaft. I told you my feelings and opinion.

1) I told you that I feel that the issue is your SLAVE cylinder or clutch master. I said this was replcaed 1.5 years ago. Danny dosen't think this is the issue

2) I told you that I do agree that it is possible that the disk is hanging on the input mainshaft. It has been a issue early with the early G50 boxes. The tech at the dealer says that this happens more than we think. You yourself told me that the tech says that HE wants to remove the gearbox and clean the input shaft. You told me that YOU feel that this isn't possible. It told you that in humid coastal cities like San Francisco, Seattle, London where it is rainy and humid that this will happen. Porsche does have a Service Bulletin about this. I told you that this could happen, I also told you that with accelerated WEAR as in hard 1/4 mile launches and heavy track use the disk media/compound will dust the spines and when mixing with grease can cause the disk to bind. Correct you did say all of this. I told you, I do not live in San francisco. I live in Morgan Hill. But lets remember, this happend within the first 10 miles of my transmission rebuilt/new umw kit. It comes and goes, randomly. I thought it was the shifter, Danny says its otherwize now.

I told you that in order to find out the problem the gearbox will have to be dropped. I also told you that it would be a good time to convert to the GT2/GT3 style slave and lose your power slave. Again I told you that I feel that this issue was related to the slave system. I don't want to do this converstion at this time. I think I said at this time i'm not interested. I feel the more the car gets modded, the realibilty goes down.

3) I did call the tech as you requested and he told me that he bled the slave system, however what he also mentioned was that your Pentosin was BLACK/burnt. Which would point to OTHER issues.

Interseting, he didnt mention this to me today. I just got back from with him. Thank you for telling me Kevin.

When it comes to clutches and brakes there is no warranty. And while I am being tossed under the bus without finding OUT the real cause. Enrrique is pissed off because I told him that clutches don't have warranty dollar paid for labor. Enrrique did NOT state that my recommendation were out of line, he just told me that he would get back with me and that he had to answer a call at work. There was no email or follow up call. We now see this on ALL the forums. A broadcast thread to blacken my product.

I was pissed off that Danny mention the clutch may be out, and thats with 4,000 miles of driving it. About 150miles at the track. I understand a clutch is wear and tear. But who wouldnt be annoyed that a clutch only lasted 4,000 miles while my stock one lasted 65k without an issue. If i said i called back i'm sorry if i didnt.

What Enrrique has failed to mention was how I helped him get his car out of another Porsche dealer that wanted monies up front to repair his broken gearbox. I made arrangement with a dealership and spoke with the manager to HELP him out and to try to cover the new box. It went one step further > Enrrique asked me to request that the dealership buy him a new clutch and try to get all the labor and some of the parts covered by his aftermarket warranty.

Correct, and i apprecaite that a lot for telling about that dealer. But what does that have to do with the current issue ? irrellavent.

We all realize that there are street driven cars and cars that are driven HARD. There are cars that are TRACK driven. The duty cycle and wear and tear is trippled. One takes the risk when you take your car on the track. We have seen all of the video and events and duty cycle that this car has gone thru. In the end, I haven't seen the clutch components. The gearbox isn't even removed. Let alone the diagnostic results from the burnt Pentosin haven't even been found. Which by the way, it is a RARE case to have our Pentosin turn Black> unless you have a heavy heat source or component failure. The steering system is connected directly to the clutch slave system.

Yes I agree with you 100% but, only 1 track day? And remember this happend since day one, since transmission rebuilt/ new umw kit.

Lastly guys PLEASE READ>>all of my presure plates are enhanced by ClutchMasters. So for those that have ClutchMaster plates along> coupled with ALL the clutches that I have sold over the years should "speak" for the rugged service that they can handle.


I'm glad your presure plates are enhanced. FWTW, Danny mention that the pressure plate maybe cracked or something. Who knows at this point.

Larry, are you calling what I said BS?? Do you think that "maybe" Enrrique didn't want to hear what I was telling him. Like, we need to see what is wrong first. And that regardless there is ZERO labor dollars for a clutch repair.. And that HE would have to authorize the repair. And by the way, the tech is telling him that HE feels it is the mainshaft and NOT the clutch.

Kevin, you are correct. I drove 100 miles to SF today to talk to Danny in person. They are doing this for free in terms of labor. I just found out today, when I spoke to the general manager. The general manager told me that Danny has no idea what it maybe. Hence they want to help out as much as possible.

Heavychevy I didn't say the track vs miles quote the way that Enrrique has written in this thread. What I did say was "Track miles are multiplied 3 time the wear of street use" I said if you have 4000 miles of track use> it's like 12,000 miles of normal street wear.

Thats what I heard, but if you said you didn't say that. Thats fine. I mention i have less then 4,000 miles on the new clutch and about 150 of those miles are track. You said thas equivelent to 12,000 miles. Still no clutch should wear out in 12,000 miles. My oem didnt.

Regardless, I have seen clutches smokes on one weekend tracking. It happens. Are you going to pull your car into the dealership with SLICKS on and ask them to warranty the clutch? If there is driver abuse, or component failure, including failures from excessive heat one has to expect to pay to get it fixed. If someone smokes this clutch kit with the Sachs GT3RS disk and reinforced ClutchMasters pressure plate>> a more aggressive clutch system might be needed such as a 4 or 6 metal puck ceramic, or fiber tough disk, Tilton or other RACE clutch kit. And believe me, these options were explained to Enrrique. Guys, I flat out told Enrrique that HE SHOULD buy the Fibertough clutch disk. I told him that based on what I have heard him tell me of his driving style. He did NOT want that disk and opted for the Sachs GT3RS disk.

I'm not asking for a warranty on the clutch. I know thats a normal wear and tear. What is shocking is that it's at less then 4,000 miles. If the oem clutch was about to take 65k miles, which is 'not as good' your kit should take it. yes I opted for the gt3rs, as i have no intensions of more power, and i still dont.

I didn't bill or charge Enrrique $4,500 of his clutch. My LWFW kits are $1,975.00 > if you want the Fibertough disk it is extra. But not $4,500.

I paid 2k for your kit and plus 2k out of pocket for the rebuilt, because the extended warranty didn't want to cover the whole thing.
Kevin, I have no hard feelings towards you. But when Danny is saying its the umw kit. Then I come to the board to ask questions, if anyone has had an issue. I hope you understand that. Theirs a lot of information that you disclosed that i did not find out untill about 3pm today. Danny mention its your kit yday, or that was his gut feeling. Yes i was pissed and annoyed that the clutch you provide would last so little, at least thats what what Danny told me yday. I don't think its the clutch. But we will see. The GM says Danny is at a loss in this one, but those are the gm words, not dannys. What i'm trying to get out of these threads, is a solution for my car. In order to get a solution, i have to disclose what my car has.

Enrique, I was on your side initially but after hearing the whole story from Kevin himself, I can't support the way you insinuated that somehow Kevin and his product are at fault. You have not even had the transmission or clutch looked at yet and you posted the banner that UMW is at fault. Plus you never told everyone the lengths that Kevin went to to help you and save you a large amount of money. I apologize to Kevin and everyone else for my statements and part in this matter.

I have reported this post to at least have the thread title changed.

Ah, that's more like it. Yeah, it's walking a fine line to get dealer coverage on anything regarding the track unless it's bone stock. However my throwout took a dump after three sessions so I'm making my dealer at least look to make sure something wasn't installed wrong, because the fact is that even really good mechanics make mistakes too. Plus I want to make sure it's the bearing and not something like the slave.

However I will say that at Enrique's power level, as long as he isn't just torturing the clutch, the sachs unit should be able to handle his power levels for years of monthly track usage. He should not have to look at those options, the Sachs 650 should be plenty enough.

And we also have to consider that 12000 street miles to a stock clutch is like maybe 8000 miles on an upgraded one?? (minus the throwout bearing which is working harder). He should have many trouble free miles ahead of him with the clutch he has now. From the sounds of things this really could be an install issue or something with a slave or gearbox issue. Which is why it really needs to be diagnosed first. Would be insult to injury for him to have to buy another clutch so soon.

fwiw I was having problems getting into reverse and first and second. About two months latter I was pushing up pentosin in front, failed slave.

I am having the GT2 conversion done tomorrow. Less to break will be nice!

I'd like share my experience with very similiar symptoms. I have 13K miles on my car. In early November last year I had Kevin's kit installed. I went to back in my gargae the nigh of having it installed and I coudl not get in into gear. I spoke to Kevin and my mechanic and both agreed to bleed the slave. Sure enough it had air. I drove it home and anothe time or two before winter and everything was fine. I took it down this spring and after one or drives, I could get it into reverse with the car running at times. We bleed it again and sure enough there is air again.

All during this time, Kevin and my mechanic, a very well respected Porsche specialist in the Chicafo area, spoke several times. Kevin was more than willing to address all my concerns. At the end of the day, both agreed that the slave was probably the source of my problems.

Given the cost of the salve and thier propenisty it has to to fail, I took the opportunity to do the full GT2 conversion- incuding the GT2 power stering pump and resevior. Probelm solved. I have not had the issue again.

Perhaps as Kevin suggests it is the slave. I know I did not go into this wanting to do a full GT2 clutch and PS conversion, but I am so happy I did.

Kevin- Thanks again for all your help on the phone and email.

f1crazydriver- Good luck- I am not a mechanic, but one I trust very much agreed with Kevin's accessments and concurred my similair symptoms to yours were due to the slave.

everyone has had more than their say..this can be settled off of the board like all other disputes....would have been much better if the problem had been determined before this was posted...thread closed...this post added at Enrique's request...btw...these types of disputes are not permitted whether they involve a sponsor or not...

UMW thread
Hey Chuck,

UMW Is not a sponsor, not sure why the thread was locked. I have no problem with kevin, do you mind keeping it open ?

If not, can you post this for me:



Kevin, I was a annoyed, not angry. Trust me, it takes a lot more to get me angry. (hahaha) What annoyed me was the fact that you were not listening to what I was trying to tell you. You also commented that I may have burnt my clutch. I didn't get on it untill about 950 miles after the rebuilt. I followed your advice, and drove in SF the day I picked up the car, in order to break in the clutch. I was trying to tell you i'm very easy on the clutch, and you suggested my driving may have something to do with it. I don't drag race my car, you know that Kevin. I'm also very easy on the clutch because i do not rev the engine to get it moving. I do it all with idle. I also always heal toe. The power steering pump was replaced at the same time as the accumulator stuff. I know the Porsche Dealer I use to take it to installed a 997 power steering pump. It probably wasen't the best way how i went about making the thread, but we all sometimes don't go about the best way. I think, that if you would have listened to me to what Danny had said, and he asked me to tell you to call him. If I would have gotten a better attitude from you, I think that would have put things in peace. I'm not saying you did anything wrong, you have a strong personality like I do. But I got the sense that you were telling me "your **** out of luck, and yeah you need a new clutch" as you mention to me that I may have gone through the clutch already. I was shocked, and annoyed thinking that your clutch didnt hold out for ****. But after calming down, and having feedback from others like Mike, I have a sense its not my clutch nor perhaps your lwfw kit. At this moment is up in the air.


Larry,

The dealer Kevin suggested, and the one was I was at before had the same conditions. Only difference was that one dealer would supply me with a one for $8,500, while the other dealer would rebuilt mine for about $6,300. But conditions where still the same. At the end of the day, extended warranty took care of it. Kevin knows that, i'm not sure what he said to you.

Enrique has requested that this post be added to this thread...

Here's an update I would like to be posted if possible. Thank you Chuck.
So I finally got my car back, after 6 weeks of being in the shop. So far it seems like the slave clutch cylinder was the issue, and it wasn’t the UMW clutch kit, as my tech thought, and I would like to apologize to Kevin from UMW. My tech was suggesting going back to stock but even thought I didn’t agree with some of the comments Kevin said I stuck with my gut feeling of why I bought his product in the first place; because I trusted him and he’s a very knowledgeable person. When the transmission was dropped, the clutch and pressure plate looked fine (clutch was not worn! You should trust your clients sometimes Kevin! ). There was some dust on the main shaft from what I was told but it was considered to be normal, at least from what I was told. There was no rusting, on the main shaft. My tech wasn’t sure what the issue was, so he called Kevin and got his suggestion. Kevin apparently told him to change out the slave cylinder clutch..and I was offered to do that or to go back to stock flywheel and clutch. If it turned out that I still had the problem, they were going to bill me for taking out the transmission and putting the clutch and back together if it turned out it wasen't the slave clutch cylinder. and so far the car seems to be driving a lot better than it was before. I would like to apologize to Kevin publicly as I put his company down. I was frustrated but I hope you understand that when my tech, was trying to blame the issue and so was the manager on perhaps being your kit, and a few comments made that my clutch may be dead, I was not the happiest camper after only 4,000 miles. I’m glad it turned out that the tech and general manager were wrong and it was not your lwfw kit, and I’m also very thankful that you helped them diagnose the problem. I’ll be swinging by Seattle on work next week and I would like to hopefully meet up with you and take you out for dinner or at least a beer!
