Would him having the 6 speed have anything to do with it?

 

Are you for real. The reason why Dirk didn't post earlier because NO ONE CALLED HIM. I only see excuses in this thread and it is sad to see the credibility of this wonderful company get thrown to the fire. Kilterman is 100% right.

Let's put it this way, Brent Rau runs an ACT with NO PROBLEM. But yet these cry babies here are crying about the clutch. If you don't like your ACT go BUY SOMETHING else. Trust me you will be back complaining about the same thing.

P.S. I guess Turbotrix runs 9's with their ACT and gets locked out of gears on their 9 second passes .

 

NOPE, I have personally installed 3 Exedy twins and 1 of the 3 has the lockout problems too and it was on a 5sp 03 evo.

 

We run nothing but ACT clutches... They are the best for a reason .. They work. Mitsu has upgraded 2nd gear and 5th gear syncros in the 03 evo.. because they are bad. People are getting locked out of the gearing because of the trans,, not because of the clutch. Yes a puck will engauge better ( its lighter ) ,, But the ACT street disk is far superior then any other clutch on the market for the evo.

Unlike other clutch companies , they actually underate their hp and tq claims. We ran the standard pressure plate for an entire season with multiple 9 and 10 sec passes on it.

We've seen soo many people change out their twin disk setups and go ACT.. Im also not a fan of the noise a twin disk makes as well..

To each his own but to blame engaugement issues on a clutch is crazy. Jeff ( driver of our evo ) has 50k on his ACT clutch and disk. His car makes 365whp on pump, drives it everyday.

YOu may know a lot, but this is not an informed response to the situation. Brent Rau and TT do not use the clutch in question here. ACT as a company is not being doubted nor questioned, but the plain fact remains that many people using the ACT HDSS in their Evo are having the exact same lockout problem, and there is no solution. Likewise, there is no understanding of what is causing the problem. If I were located in the same general area as ACT HQ, Dirk would happily take my car, tear it apart, and try to diagnose the problem, but since we're on opposite coasts, that isn't possible. In the meantime, I have no solution other than the adjustment of my clutch pedal, which is working currently, but isn't likely to work for long. The only hope we have is that one of RRE's customers encounters this same problem and offers up his/her car to ACT for examination.

I cannot imagine why you would think the ACT I'm using is the same as what Brent Rau is using. Additionally, Dirk told me a LOT about Brent Rau's situation, and you don't want to begin to get into that. There's a whole lot more to it than him just using one of their off-the-shelf clutches. Dirk and his company did a lot of work to get things working for Brent, and the result was wonderful, but it's not like he just grabbed one off the shelf and it worked.

Dirk and I had a good conversation, and I appreciate his time. There was no resolution or change to the situation, but I plan on keeping him informed with how things turn out in my near- and long-term future, as I will be road racing next weekend, then I will hit the drag strip again just to see how the shifting holds up. I will also be sending him my clutch assembly if and when I upgrade to a twin disk (Tilton probably).

 

Dirk doesn't think it's the tranny, otherwise the pedal adjustment wouldn't make a difference. I don't even have a 5spd, and my synchros were never a problem. There hasn't been an MR yet that has complained of synchro problems, so I do not think this lockout problem is a synchro issue (nor does Dirk). With the same sychros and same tranny and no changes, people have used the ACT street disk and gotten the lockout problem, then have switched to twin disks and not gotten the lockout, so it can't be a simple synchro issue. I'm sure there are individual cars that have synchro problems, but this is not the case for all of them.

 

True ..but i think your issue might not be the same as like someone with an 03'. They upgraded syncros for a reason. I've seen people who cant grab 2nd gear and have someone else drive their car and dont have a problem. Wish you luck.. i can only speak from past experiences.. Yours sounds like one i've never come accross..

I have a ACT Street Clutch with same problem. My car is a 05 and only 9000 miles on the odometer when the clutch was installed, before the ACT it was flawless, after installation of the ACT the lockout problem started. Its not only on 03 EVOs.

 

All I know no one will be buying any ACT clutch for the Evo anymore.
I've been racing for 10 years. I know the shifting in the Evo sucks to begin with but the Single disc is definitely causing this. There are so many people with this same issue. It can't be everyones driving. I can shift super fast below 7k but can't above so that explains it.

 

BLAH BLAH BLAH BLAH BLAH Listen NEWBIE, I been in DSM's for over 8 years. I know Brent Rau's setup and well as the set ups of Sean Glazier , David Buschur, and Shep. WHO GIVES A FLYIN ***K. A DSM and an EVO are different. Please tell me something that is relevent.

PS - I posted on this thread and no one called me. Funny how that works.

On topic though, glad to see War and Dirk talked and are on a progressive path.

 

awww, hims feel left out? It's prolly because no one likes you.

 

Someone hand me a tissue. LMAO

 

I will say it again just in case people didn't catch it before: Don't assume that there is only one issue here and it applies to everyone or every single disc clutch. That is simply not the case.

For some people it's simply adjustment, for others it might be defective or worn syncros, for others it is improper installation or loose bolts, for others it is poor pressure plate/flywheel design, someone else can have damaged parts, soemone else will have increased torsional vibration, and there might even be people out there with bad thrust bearings or crankshaft flex. I have seen at least three of these on the EVO and the symptoms are similar.

 

Speaking of which, are you guys going to release or have you released a flywheel for the EVO ?

 

We are not assuming everyone has the same problem, we are just saying that everyone that has the problem has an ACT installed. And some people that got rid of the ACT, also got rid of the problem. I think that tell us something.
