I really enjoy the comp stage 2 on mine with the comp tob and oem flywheel. It has over 20,000 miles and has been great to drive on.

 

What type of driving are you doing mostly?

 

this always makes me curious. nobody i know has had any lockout issues, and we've all used ACT exclusively since 2001. i'm trying to figure out why some people have this issue and some don't. i wonder if it's a throttle hang problem. all of us have had that tuned out of our cars. have you fixed yours as well?
as for the noise, that's kinda weird too. i especially don't recall having any noises with new flywheels and clutches.
it's interesting to see so many people with so many different experiences with the same clutch.

 

Hard driving

 

here is a video of the noise after install during break in period. went away after the first 500 miles

I have adjusted the clutch pedal and it seemed to help with the lockout out but I do get it occasionally. And mostly during cold temps its hard to put in gear. I will say that after the install I did noticed an increase decel noise level and 1st gear whine.

have you launched it? drag racing?
personally i'm looking for a clutch that will hold up to some road course/time attack abuse with maybe some drag time. all with about 350-380tq to the wheels

 

Just about finished with break in on my stage 2. Using oem flywheel, act monoloc and the comp tob. Everything's perfect so far. Much better than the oem replacement that was in there.

 

this sounds a lot like transmission issues. shifts better when the fluid is warmer? clutches don't (typically) shift better after warm up.

i have noise on decel as well. i have had that with any aftermarket clutch in any car. no clue why, though LOL. 1st gear whine also shouldn't be a clutch issue. that sounds like trans or transfer case.

as a point of reference: my HDSS worked great with the power in my sig. i do Time Attack, HPDE, and autox. i tried the drag strip once, though, and it wasn't happy. you may wanna jump to the 6 puck. it holds a TON of torque. just my experience and $.02.

 

Thats good to know. My main focus with my future build is to do time attack/road course and an occasional drag event. But i want a clutch that will have great street manners as well. Now this setup has lasted a pretty decent time. But unfortunately my knees are not getting any better and the xtreme HDSS pedal feel can become a little much at times. Dont think im going go with any puck style clutch it will definitely be a full face plate. My max power goals will be 500-550hp im guessing tq will be just north of 400 with my planned build in kill mode (drag/topspeed pulls) and anywhere between 450-500hp for the street/time attack modes. Truthfully my current setup should be able to handle. I guess ill just have to make an effort to never miss leg day at the gym

Now that i think about i may just try their Regular HDSS. The difference in the xtreme and regular hdss is 55ft/lbs of tq capacity and the xtreme has a stiffer pedal. Kaj you have the regular HDSS pressure plate, correct?

 

i hear ya on all that. the HDSS is good for 510tq, but that's not at the wheels, so figure in drivetrain loss and it's more like 400tq. that would be pushing it for you, i would think, depending on your setup though. the 6 puck with HD PP is rated at 650tq which should be about 520wtq. i'm actually bumping up to the 6 puck because i don't daily the car any more. i don't believe they sell an extreme PP with the street disc. even if they did, i've decided on the puck/HD setup because, since i road race, i prefer a softer pedal feel and lighter/quicker engagement of the pucks (not that i had a problem with engagement of the disc). the sprung puck is a bit more forgiving, if that helps. once they are broken in, i haven't had any issues with daily driving a puck disc. other people that drive my cars tend to stall them, though haha.
yes, i just took out an HDSS.
FWIW finding a good clutch for a drag strip AND street is a tough one. with the torque level you will be at, i'd say pretty much impossible.
again, this is all just my opinion. do you have a way to test out any other clutches to see how you like the pedal and engagement?

 

you should get the ACT HD ME2-HDSS. i recommended for street not drag. i have that clutch installed on my 610 whp evo 9. THATS THE ANSWER ACT HD, OEM FLY WHEEL AND ARP BOLTS.
