What causes High RPM lockout on ACT clutches?
In case you missed it, we do. It's called a "race" disc or puck disc and it is designed to hold up to more heat and abuse than a organic disc. Which if you've been reading this thread like I know you are you would see that the majority of the lockout issues reported are on the "street" disc which has a lower threshold for heat. An organic disc is not immune from the laws of physics.
It also appears that you also missed my % reference that you're attempting to quote, it was used as an example for reference, not a statement of a goal that we strive for. Every manufacturer aims for 0 failures I know of non that can claim that. But thanks for the witty puns and play on our names.
BTW what was the point of your original post? To attack ACT? Start yet another " I hate ACT thread"? it seemed that the original intent of the post was for information which has turned into a play on words. We've answered your questions a few times over so what's your agenda?

Get mad... and then ramble about stuff I wasnt even talking about such as being an expert on clutch design lol. BTW like I didnt know what clutch these guys were using 
Sorry man I just cant set here and take up for a clutch company that has screwed me... told me ridiculous stuff over the phone when i call for support of why there clutches don't disengage, get lockout and all the other problems Ive had from ACT clutches over the YEARS... and has issues they wont fix and just keep selling there products. I have a right to my opinion. If you don't like it then just keep getting mad and rambling i guess... I mean don't take anyone serious and try and fix your clutch issues or anything.. That wouldn't make any sense...

I'm also not really interested or have any need for you to "take up" as you put it for ACT.
Sorry if you feel that you've been burned by us in the past, you do have a right to your opinion and at no point have I suggested that you shouldn't come on here and tell us just how unhappy you are with us. By all means knock yourself out.

Now that is funny because I see just as many problems with your puck "race" clutch kits as the street set up. Maybe if you read the thread better you would see a large majority of complaints on your product for the EVO. Yes maybe you have some great clutches for other platforms, but when it comes to the EVO, I think you guys are just not willing to admit there is an issue, that should get noticed. You're right no company has a 0% failure rate, or defective product rate, but atleast there are companies that will work with you and not leave you with a crapped out clutch when all is said and done. If you have not noticed several people have already chimed in that you left them hanging in the wind and screwed. I've seen you guys do it countless times over the years also. Every time I think about buying an ACT clutch, I research your feedback and sure enough, same repeating stories come around. ACT left me unhappy, mechanical issues, what have you.
As for my agenda, well it started off trying to gather info on the lock out issue, but after seeing how many people have chimed in on how ACT treated them, my agenda has shifted to trying to get the people over at ACT to pay attention and make note of all the issues at the very least.

Again a simple search would have given you several threads with posts talking about lockout by both people that have lockout with our clutches and those that don't. In addition you would have seen comments by me and the owner of ACT relating to the issues mentioned.
This weeks edition of "I hate ACT and their clutch" is no different than the other ones on here. If you don't believe in the product and us, then don't buy it. Claims of making threads in search of answers to a question that has been beat to death by both sides or to draw our attention is suspect to say the least.
<-- Lockout ONLY at the drag strip at high RPM. I am going to guess and say that it is the organic disc (HDSS) heating up from the launch and causing this problem. From a roll, I have no problem shifting at high RPM. I have not adjusted the clutch pedal yet but I don't think it would help. I will try this upcoming season. Either way, I am going to run this clutch til it breaks on me.
if you are posting in this thread to bash ACT...this is your warning
anything after this post will receive 5 points for vendor bashing
no way everyone will be happy with a product...doesn't mean you make slanderous comments about the company and their product

I HATE ACT!!!!
I hate them for making an excellent product
I hate them for having AMAZING customer service
I hate them for actually taking the time to respond on public forums.
I hate them for having decent prices
and I hate the fact that I will buy many more ACT clutches for my vehicles in the future!
Bash Bash Bash the bashers!

I am no experienced Evo owner, this is my first 4G63 powered vehicle. My car has an ACT street 6 puck, and I have no comlaints about it at all. I daily drive it and myf irst trip to the strip was last night, other than a little clutch smell, I thought it performed great!
Hold on here.. I'm not bashing them. I even stated I would love to run one of their clutches, but with so many unhappy customers it's hard to take that chance. I'll admit the way ACT has handled a lot of their customers had ticked me off to say the least, and it ticks me off more to see they are so passive about it. Like I said I could see if it was the drivers/installers fault every time, but it's not. Maybe some think $500-$800 is not a lot of money to spend on a single disk clutch, but I beg to differ.
ACT I didn't intend to talk you down, but the manner that you respond is most always a pass the blame onto someone else issue. All I wanted to know is why your clutches seem to have more issues with warping and lock out more then any other clutch. I didn't complain about your clutches, I didn't ask for others to chime in and protest their problems with the product and or service. I added in my experiences with you guys on the service, and I'm just stating facts. I never got nasty about it, nor did I ask others too.

Centerforce clutch $784.59 + shipping
RPS clutch $719 + shipping
Clutchmasters $616.20 + shipping
Exedy $503.99 + shipping
I got my ACT HDSS for $499 shipped!
So yes, ACT's prices are very good/reasonable considering the competition!
Yes, I sound like a ACT fanboy, but that's because I have had nothing but amazing experiences with them. The only time I have had an issue with an ACT clutch is because of problems with the install (including install problems that I caused)
The failure rate I have had on properly selected/installed ACT clutches has been ZERO including no high-speed lock-out on any of the clutches I have installed.
I cannot say that there is 100% satisfaction on any other manufacture of clutches I have installed including OS Giken, Clutchmasters, Centerforce, TRD, RPS and others...
Like I said before, the only reason that you hear about lock-out on ACTs above others is because there are so many more ACTs out there than any other clutch.
Well here is a great question for you then. Why have I not heard of a lockout issue ever with a stock clutch? EVERY evo has had one, yet the only problem they suffer from is slipping/wearing out.
Yes ACT's pricing is good I give them that, hands down. Even so, $800 is a lot of money for any single disk clutch, for any car. Also my main point was that $800 is a hell of a lot to not be happy, hell even $500 is a lot of money to not be happy is not my bag of tea.

A quick search on both lockout and disengagement provided the results below. Yes there are similar ACT threads but I'm posting for the people on here that claim to have never heard of having to make adjustments, lockout etc. on other clutch makes.

Correctly installed and adjusted ACT clutches do not have high RPM lock-out.
I even had lockout with my exedy organic(by far the worst clutch i have ever owned).... so i just dont think it is LIMITED to act. But thats just my .02 i just got my act 6puck for my evo... and i have had act's in all my previous dsm's and have been very impressed.
