No worries, Google has my back.
Please don't make this thread about the Fidanza flywheel. Yes, TTP sells it and has great things to say about it while you are ready to give them your money, but for some reason, they, and many other people on this thread still don't get it.
Stop pretending that I'm the only one with this problem.
Go re-read the first post, the list grows by the hour.
Stop pretending that it's installer error, or there's any other tweak or fix for this problem.
The clutch feels fine, holds power fine, and shifts fine in every case EXCEPT high RPM shifting.
Stop pretending that other clutches have the same failure rate as the ACT's.
There are 4x as many ACT lockout posts than there are non-ACT lockout posts.
Stop pretending that 7500RPM is too high to shift any street disc.
It's below the factory rev limit.
Stop pretending that ACT is not to blame for continuing to sell a poorly designed product, and never once admitting to themselves or to the community that they just got it wrong.
It's not my flywheel, it's not my bushings, it's not my motor mount, it's not my pedal, it's not my mechanic.
If there is any shop within a few hundred miles of Boston out there who is confident that the ACT clutch is not my problem, I will make a deal. Take my car, install a brand new ACT XTSS clutch kit and whatever flywheel you choose.
If your expert installation of your precious ACT parts 100% solves my lockout issues, then I will pay you DOUBLE MSRP for all parts and DOUBLE your labor rate.
In addition, I will make a thread entitled "ACT, I love you" and I will retract every bad thing I've said about them.
If, however, it does not solve my lockout issues, I will owe you nothing and you, as a shop owner, will publically admit that ACT's product is 100% the cause of the problem.

Quoted so you can't go back on your word.

Another great find. TTP not only sold & endorsed Fidanza + ACT combos, they actually told a weary customer to be sure that it would work because they install them all the time.
This thread just makes TTP look silly

Stock limiter is 7606 on Evo VIII and IX. 7599 on Evo X.
My VIII locked out at about 400whp Dyno Dynamics. I could shift at 7500 at ~350whp when it was trapping 118, but to trap 120+, it would lock out right at redline. I detuned it for drag racing because of this.
I couldn't hold 1-3 without missing the next upshift. Stock flywheel.
Went back to a stock clutch and could upshift on the limiter no problem.
The ACT clutch did engage fast and never missed the upshift at 7000rpm or lower upshifts. The turbo I had needed the RPM. Shop I used has installed tons of Evo clutches. I would not go as far to say ACT sucks, but I have seen high power high RPM lockout rather often. Things like pedal pressure and feel are subjective and not what matters.
In this car, I'll use the stock clutch as long as possible until it won't work any longer, then go to an Exedy twin. Until that point, no drag racing for me.
If ACT released a clutch with a milder pedal that was proven for high rpm with a little better torque than stock, I'd buy it the moment I needed to upgrade. I do think they are a good company.
We did take down the fidanza from the site. We have about 400 Evo products that have been added over the last 5 years. There are parts and prices that have been outdated for years. As we have stated already we do not currently recommend Fidanza units. Over our years of tenure installing and maintaining hundreds of drivelines since 05 we have seen problems over and over. Even had our tech have a Fidanza 6 puck fuse to the Fidanza flywheel. The Fidanza flywheel is not something that has been sold or endorsed in many years and while you did us a favor and pointed out the one of many outdated parts back from 2005 when the site originally went up we found it an oportune time to remove it entirely.
True, but at the same time TTP's online store isn't kept as up to date as they are. Back when I first got my evo I had contacted them about a couple products that they had in their store online to get a price quote. They had suggested alternatives instead that were cheaper, and that I would later come to find were just as good quality wise. I can say personally that they have been a good help in recommending options for my evo that were very cost effective and proven to work when I contacted them, I don't think they have ever recommended a product that was more expensive than the one I was inquiring about. Just wanted to say that having personal experience with TTP. Not a lot of vendors will come into threads like this and give their opinions and share their experiences.

I understand. No hard feelings. I really do have a ton of respect for you guys, and I'm sorry that we came to blows in this thread. It's just too easy to get defensive online.
Thank you for your wisdom on the ACT XTSS. Everyone agrees that at least on SOME level, it is to blame. And for that reason, I think the community benefits from this thread. It's a rant, yes, but it's constructive in that we've reached this important conclusion.
ACT makes a lot of great products that people love and trust. But a perfect street/strip single disc clutch kit is not one of them. It's a shame, because it's SUCH a popular part, being so inexpensive and from such a good name.
To those out there potentially buying an ACT single disc clutch, maybe you'll have problems, maybe you won't. But at least you can't say you weren't warned.

HAHA I agree 100% this has been know since 04-05 maybe even by some since 03 here in the states.
I have used ACT in my previous Honda models without issue. The HDSS does not work in my EVO past 7500-7800 PERIOD and because of that I'm not willing to give ACT another chance in the EVO plain and simple
Its been in the car for like 70k now and it's great for driving around and holds the power my 35r varient car is making just fine but high rpm shifts are simply are FTL you live and learn. Thank goodness it's almost time for it to become target practice
