me raping it on the street is exactly like me banging thru the gears on the track lol. with the 8 launch thing i was just saying since day 1 it started to be abused. i wasnt saying i only have 8 launches total on it....i also didnt mean to imply i havent put nearly as much abuse launch wise on it as you. but me running thru the gears on the street is the same way im shifting on the track.

 

No, it's not the same, sorry. I drive hard on the street daily, but it's nothing like putting together a perfect launch and 3 perfect shifts en route to a 12.1 or whatever. I find it to be MUCH different. I know you haven't just launched 8 times, but you gave no details on how many times you've been to the track, what you've run, what your 60's were, etc etc. Without that info, I can only assume you haven't really tested your ACT to the point that you would encounter the problems I have, especially since I didn't encounter them until after 15 or so 1.70 60's on the way to 12.1-12.2 ETs.

 

Well....If i would have known this prior to getting the ACT SS i would have never purchased it in the first place. From what seems on my car..my 4th gear syncros are dead. Now it doesn't seem like so much of a mystery as to way they are. I haven't launched my car yet since i got the ACT SS which was about 4-4.5k ago. I haven't reved it to about 7. and i haven't really had a problem with lock outs...Only time i experienced lock outs was when i first installed it, and it was cold out. (cold engine). But it seems as tho ever since the ACT was in the car. my 4th gear syncros just passed out so.. just thought i'd share my experience.

ill agree that street launching and track launching along with banging out 2nd but for me 2nd on is still the same. i dont have as many launches on it as you no doubt about but dont turn this into you thinking im attacking you or anything and tell me i have not even come close to what uve done to your clutch...ive also ran the same times as u and have probably 10 1.7s on it and a few 1.6s. who knows i can go back out to the track next time and after getting more launches at the track on it start having the same exact problems as you. i was just telling you my experiences so far with the act in no way was it meant to be an attack on you if thats how you took it.

 

Warrtalon, don't get carried away w/ bashing the ACT clutch yet. You may just need a freeplay adjustment on the clutch pedal, have you tried that yet? It's not hard to do.

 

Chill with the ego, other people have been complaining about the same thing for awhile. Just be glad you were able to get that many launches/good times with the clutch without locking you out

 

I just had my tranny rebuilt, and let me tell you even though the car's clutch felt fine the disk was low. Perhaps from slipping the clutch while launching. I think you may need a new disk. As the material on the disk wears out I think it has a harder time stopping the transmission from spinning. Thus causing the mis shifts and lock out. When I get some more money in the near future I will ce looking into the exedy twin carbon disk. A.C.T is a very good product for the money.
LONG LIVE A.C.T

 

i have the same problem at the track, i get locked out of gears. at the shootout in 96 degree temps and 100% humidity Best run was 12.6@112mph with a ****ty 1.87 60ft because I spun at least one tire all through 1st gear. In my talon tsi i pulled 1.70-1.72 60's all day and ran 12.7@106mph so I know how to drive and how to launch.

I've done about 40 hard launches on the act clutch, i launch it all the time on the street, track whatever. My mph was good but I couldnt get into 2nd or 4th with any sort of quickness. my 330 and 1/8 werent anything good.

and to make matters worse, my clutch just started slipping in 4th and 5th on the highway. So i might get the extreme pressure plate with the 6 puck sprung disc.

 

Hey, I had the same problem with my RPS Carbon Carbpn Twin disk clutch, not leting me in on 2nd and 4th on the track above 7000 RPM. Sometimes it works sometimes not, try to figure.
Now I am doing that TSM for the input shaft, so I'll see if that would change anything.

 

This is exactly the problem that I had been living with for the last 2 ACT clutches. When I posted about it last year, not a lot of people into it. Most were thinking it's either installation or bad shifting but I found that it was not since on the second clutch I did let a very good shop (RRE) installed it. I never get this problem on my stock clutch in many drag events.

Due to the lack of populatiry about this problem at the time, I didn't get enough help. One time, I though it's a tranny problem and almost send my tranny out for a rebuild. But switched to the Exedy twin, it seem that the problem go away according to the last drag event. I'll find out more about it on the next event.

Warrtalon,
I hope you will get this problem fixed man. Yeah! it's hard to put up good number at the drag when the clutch is acting up.

 

This is strange to hear that you are having the high RPM lock out issues after your clutch was functioning correctly. All of the people who I have talked to had that problem since the get go. It seems that something else may have gone wrong with your clutch. It seems this is an issue with alot of the single disk designs regardless of manufacturer. The weird part about all of this is that I never had a shifting issue with my stock clutch. I would go through the gears like a mad man and I never missed a shift.

 

I wqould not blame this on the clutch right off the bat...there are ALOT of other factors at play, all of which could potentially cause the same thing. The only way to diagnose to start the process of elimination

 

You are right, but it's just the most likely first guess, since it matches exactly what others have experienced with the same clutch. I will be trying several things to include:

SS clutch line
Remove clutch restrictor
New tranny fluid
Pedal adjustment

I will report on how/if these changes make a difference. If I end up back where I started with perfect shifting, then I will make an additional post emphasizing that my ACT was not the problem. I only hope that's the case, but I'm not expecting anything...

 

Yes, on the stock clutch, I could hit any shift with lightning-quick efficiency without the hint of a grind or lockout. I ran 12.2 at 110.7 on the stock clutch while still on the cat-back and only 104 unleaded in 80-degree weather while last night, I had all the same mods PLUS dp/tp, fuel pump, boost at 24psi, and 116oct unleaded, and low 70s, yet could only produce a 12.44 at 110.2. I attribute this entirely to the poor launches and poor shifting. I know my driving ability hasn't changed...

 

Well, I have tried 3 of the 4 things that you have suggested above. To let you know I have a new Centerforce Dual Friction Clutch and a matching Centerforce Flywheel. From the first day after I broke my new clutch in, I was totaly locked out in my 1-2, 2-3, 3-4 shifts. It only happened at 7,000 to 7,500 RPM. At normal shifts the transmission behaved normally. Adjusting the pedal height higher made a big difference, which now allowed me to go into gear at high RPM. I still had to muscle each gear, but it went in. I ended up going with a SS clutch line which also removed the restrictor. That along with raising the pedal to the point where there was no threads left on the rod, greatly improved the feel of the clutch and made my high RPM shifting more consistant. The shifts are still not smooth like the stock clutch and the clutch pedal is very high up. I don't like the end results, but I can now shift at high RPM's. Unforntunately I do not have the money to change to another clutch, so I'm stuck for now. On transmission fluids, I started out with BG Sychroshift which left my transmission shifting very notchy. I then switched to Red Line which made a slight improvement, but not much. My last resort will be Pennzoil Synchromesh to see if the shifting will smooth out.
