Yeah, I said the same thing after my first trip to the track with the ACT. I said it again after my 2nd trip. Then, after my 3rd trip, I could no longer shift at 7k or above...

I, too, ran my personal best 60' and 330' with the ACT, and that included a pedal adjustment initially. Let us know if you can still shift fine after a couple more trips to the strip.

 

Maybe there just aren't that many around you who are racing with any regularity? You said there was no drag strip in the area. This isn't a problem that surfaces on daily drivers unless their pedal is way out of adjustment...

 

Do you have hook-ups in CHicago area that I can bring my car in for the check-up ??

Thanks.

When or if I run into problem with my ACT clutch I will get it the pedal adjusted and if that doesn't work then I'll just have to get a new clutch. Did you think the clutch was going to last forever with you beating the **** out it? What exactly do you want ACT to do for you? Why you don't just get a twin disk?

 

[QUOTE=blitz118]
I think a bullet just went pass me toward a crowd Whatever the problem is I think we all need to get along and work it out. I'm not sure if it's just the ACT clutch but a bunch of people are experiencing the same problem. It could just be that the clutch needs adjusting.

Some opinion and views could be out of hand but telling someone to go and get a new clutch just because yours work is not the way to approach this and resolve issues. They spent the money already and expect to get some decent performance out of it.

I have the ACT as well and have the lock-out issue. It was locking out on the street and then at the track. My brother ran twice with my car and lock-out both times 1st to 2nd and 2nd to 3rd and decided to quit before damaging anything further. I adjusted the rod to have 2 threads left. It helped and shifted better but lock-out problem still exist. I adjusted to 1 thread now and still have not try shifting at high rpm. Need to find an open road.

 

Whoa, take a breath. I didn't expect it to last forever, but I did expect it to last more than 2 months. That's the thing, though, the clutch itself is fine, but there's some combination of factors that is causing this weird lockout problem, and no one knows what it is yet. I only made 10 passes before I experienced the lockout problem, so I don't think that's considered "beating the **** out of it," but maybe we define that word differently. If you think it's fine and dandy to have to purchase and install a new clutch soon after purchasing and installing a clutch, then I don't know what to say. I'd prefer that it work a little better on a car with so little hp (295whp here).

I don't want ACT to do anything for me; I just want the clutch to work.

Why don't I just get a twin disk? Uh, is that a serious question? Let's see, it costs more than double what my ACT cost, I only have 295whp, I drive my car daily to-and-from work, I don't want to deal with lots of chatter on a new car that is daily driven, and I don't want to pay for another installation 3 months after the first one...

 

My ACT is working fine, so I don't need a twin disk. It's obvious the clutch doesn’t work for you, so maybe you should try something else. If you can’t afford a twin disk and are not willing to put up with there quirkiness, then I don’t know what else to tell you.

Do you want ACT to pay for another clutch and installation?

 

Yeah, I know. It's just that my car is in pieces right now because we're putting in an EMS.

Maybe I'll see if I can swing by RRE on my way back to Phoenix on Wednesday.

 

You guys should take the time and read through the posts

That's the thing..he shouldn't have to try something else. It should work. The ACT is advertised to hold almost 500lbft tq. Nowhere does ACT or any other single disc with this problem say you shouldn't buy it if you race or shift near redline. They sell it as a clutch designed for that type of use.
I got almost 23k out of the stock clutch without a single adjustment and no lockout issues (stock clutch line and restrictor in place). That was with 2 years of racing..high rpm shifting (7700rpm) and launching it at 6000 rpm at autox's with sticky Hoosiers and Victoracers. Shouldn't the aftermarket clutches be even better?
I can't believe some people are writing it off as the buyers problem and not the companies.
Because of the issues with the single disc I have an Evo sitting in my driveway with a slipping clutch until I save a few more $'s for a twin disc. The twin disc's I've driven shifted lightning fast and had nice engagement. IMO the noise they make isn't all that bad either.
I think ACT is a good company and I think Dirk is a good guy. Dirk has been quick to answer all my emails almost gaining my business back a few times. I just don't want to spend 8 hours installing a clutch that might need replaced after a short time due to bad shifting.

 

I finally got the page together. It took a little longer than I thought because I got carried away a bit. It will come in handy later as a training tool though. I hesitate to revive this thread since no one is going to bother to read through it all, so it just makes ACT look bad.

Like I said, we are still desiring to do some testing so it not going to answer every question, but hopefully it will give the reader a better understanding of not only the EVO clutch but clutches in general. I had my IT guy put it together on a PDF.

I read through this whole thread and I believe you guys.

At the same time I know a few local guys in So-Cal that have
2004 GSR Evos with ACT clutches. Two Evo owners have the street
disc and one has the 6 puck race disc.

They race, daily drive they're highly modded Evos without issues.

I asked them how they liked the ACT clutch and they had nothing but good things to say. The guy with the 6 puck race disk said it's real grabby and difficult to drive
in traffic.

So at this point, as a newer Evo owner I have to wonder what clutch will be the replacement clutch when the stock one wears out.

Not being a launching Evo drag racer, The stock clutch is fine for me.
I'm not willing to give up any street drivability what-so-ever.
Nor will I tolerate any two or three disc noise.

If I had to replace a clutch today, It's looking like it would be the stock
clutch again.

My experience so far with the ACT is that the first 6 months were fine (only drag strip once). After that, the 2nd time I went to the drag strip, I found it super hard to get it into gear. Then one day when shifting at 7000 rpm into 5th, I heard my 5th gear synhcro bust and it started to grind. Got it fixed under warranty. 2 months later, shifted into 5th at 7k, and boom. Synchro gone again... Now I don't know if this was because the ACT but a local shop near me told me the ACT would wreck my tranny.

 

But cars are having problems with 5th gear syncro with stock clutches too right? [Search] So do we really think that the problem would be caused by the ACT? Or maybe the same problem that is being readily warrantied by MMSA with all the other stock cars?

That is a AWSOME write up!!! I recommend it for sticky status.

The crank flex sounds like the number one suspect with the 7,000 plus RPM lockout. Any more reading material on this subject?
