If you are having this problems make sure you have all your bases covered before coming onto the boards and blaming a product.
-Check your engagemnet point.
-Change your fluids more regularly.
-Lastly, you might have a bad tranny.

 

warralton, you say u shift differently at the track racing or and on the street. do u just not use the clutch pedal to shift at the track, or just to engage it into the next gear? im sure wot shifts just arnt very friendly to ur tranny anyway!

 

You can't expect parts to hold-up if you are racing the car week in and out trying to break a record for the 1st MR in the 11's, and have the fastest time with just an AFC and intake. Power shifts, sub 1.8 60 fts, lauching the car above 5.5K, removing the limiter, etc. and you blame ACT? Is the ACT clutch you got a racing clutch? If it is not, you need to get a racing clutch! There is a difference between a racing clutch if you do lots of drag and course racing, and an after market clutch for street use. I am sorry to hear you got issues with the clutch. The Evo is a high maintenance car once you mod it! You can expect parts to break and wear much faster than a stock car. You got to pay to play! That is the truth. If you would drive the car normally, the ACT would last you for ever. Get a Twin Disk Carbon. Seems that is what you need. You purchased the ACT and that is like having a family of 4 and buying a Mazda Miata. Wrong car, wrong application. You are going to tear it up, buy an Excidy Twin or RPS Twin. Good luck.

 

No! I think you're the one that should be labeled "rediculous". You try to tell that the problem is not the clutch by showing an example of yourself with a different clutch and conclused that since a company is in business, no way in hell that it'll make mistake. Common man! You didn't even read the thread and its related threads. I'll not concluse that ACT is a caused of the problem but also I can't find a reasonable explanation why after installed the Exedy twin the problem go away.

ACT is a very good affordable clutch and only it'll even better if the problem of high rpm shifting that some evo owners having could go away. I went through 2 ACT clutches already and know exactly the symton. You don't wear the shoes yet so you don't know how tight it is.

 

I'm not sure how he shifted but I was shifting fast but not no-lift shifting. Push the clutch pedal in and shift as soon as the pedal hit the floor, simple as that. With the ACT, I'll have to wait for the rpm to drop which take about a second or 2. Some of you seem like just jumped in this thread and already making assumption statements. He need some helps from the clutch experts here not interrogation.

 

I didn't try to break any record and still getting the problem immediately at the drag shifting at high rpm. If you don't have anything to say that help then don't come in and making "funny" statements and examples. Thanks a lot.

 

I don't know if he did. But I and some other members that were getting the high rpm shifting problem already tried all the things you listed. No go.

 

Is it possible that these single disks are just hard on our trannies? Some ppl have a worn tranny to begin with hense lockout from day 1. Then it is slowly occuring with others who had a perfectly fine tranny to begin with and these clutches are just wearing them down.

 

G20, I appreciate the concern, but do not get too upset, because these guys aren't being any more harsh than I am on other threads where I see some sort of tom-foolery. The truth is that it may NOT be my ACT specifically, which is why I am going to do many of the things suggested and report back with my findings. Here are some things I'll do and some possibilities:

1) SS clutch line (changing next)
2) Restrictor (could be causing problem, but changing with ss line)
3) Fluids - I've only changed at regular intervals, nothing extra
4) Pedal adjustment - it was perfect for the first 2 months, but I didn't know it could change so drastically so immediately. My stock clutch was perfect from day one and was still perfect until the PP and flywheel got fried. I was able to shift flawlessly all the way until that last moment, so I don't know why my ACT would change the engagement point in much less time with much less racing done to it.
5) Tranny - the tranny could have worn down from racing and just now be having troubles. I highly doubt it, but we'll see. I had 0 symptoms like this after 35+ drag passes in the low 12s on the stock clutch. After 15 passes on the ACT, I can no longer shift whatsoever.
6) Shift style - yes, I lift, so it's not NLTS that's causing this. I have used NLTS on my 3-4 shift about 10-12 times total, most with the stocker...
7) Racing frequency - the ACT should have been fine for me, because I do not drag every week. I've only been to the drag strip 7 times total, 3 of which were on the ACT. I have fairly low HP, so the ACT should have been fine for my application. Instead, it no longer works properly, and I fear it may be damaging my tranny each day I use it...

 

someone (think it was a mod) said that in his opinion it is the PP causing the prob. there may be some truth to this...not sure at all though.

well i changed my clutch( while waiting on the RPS twin) to the Spec clutch....used back the PP and my original flywheel. i had the spec there doing nothing so i decided to put it in.

result= same problem.


now just waiting to put in the rps and see.....supposed to be here any day now..sigh

 

HAHA. maybe it wasn't the shifting why the Sti beat you.

 

Off topic::
We use EcuTek. Yes we do Flashes and have had great success with them.


On a side note,
We no longer Recommend ACT 6 puck clutches for the EVO8.
We have installed 3 street discs from ACT just this week and so far so good. They also do not Track the cars as we may.
My recommendation to anyone on this board will be to save your money and Buy an Exedy or Cusco Twin disc. (Its an unity clutch)

Stock like feel and it will last you forever if you treat her right.
Once you abuse her at the drag track though any clutch can fail in time.
As far as the shifting is concerned, on many occasions we have changed out the ACT and solved the problem every time.

 

Actually, yes, I would still recommend the ACT w/street disk to anyone who needs to replace the stock clutch and who does not drag race with any regularity. The occasional rap through the gears on the street will work fine while feeling just like stock (imo). I only think this problem arises with somewhat regular racing and/or when combined with a worn tranny (synchros?). I absolutely loved my ACT all the way up until Friday when everything suddenly stopped working, which was very strange...

 

warrtalon....did that clutch ever smell from being burned when getting those low 60' times?

 

Yes but those mutiplate clutches are SOOOOOOOOOOOOOOOO Expensive and the install you get raped on too, it's like $2000 out the Door Vs. less then $800 for the act installed, that is the issue.


Not saying you bad or nothing, I justy find it curious that a Vender would OBVIOUSLY push the most expensive clutch.
