ACT HDSS longevity

[o-townFLA]

So as the title states whats the longevity of the ACT HDSS that so many Evo rides are pushin...?

Plus could you add in what all has been tossed at it, such as launches, track use, HP/TQ numbers, etc...

And I know, I should get an Exedy Twin but thats another topic...



Thanks for the input :mitsu:

[GilbertFlores]

ive had mine for almost 20k now and with launches, canyons, and DD its held up good. i have all the basic bolt ons and stuff and so far so good. no sign of weekness or anything

[koolguy21]

I had mine installed last month. It feels a hell of alot better than stock(alot of torque). I can't put to much info on the subject but I would also like to find out what it handles since I'm still breaking it in.

[Sean penn]

the act will out last the exedy any day.

[GilbertFlores]

just break it in properly...dont drive like to vegas because u break it in over time....but i think the street disc holds like 500tq or something. i think disc for disc its way better then the exedy clutch unless you go twin disc O0

[SoCalRedLine]

ive put 15K on mine so far. no problems.

Never DD on a twin-plate clutch. Its bad for the plates inbetween the clutches. They overheat and cause problems over time.

[Sean penn]

2900LB= 497FT/LBS tq act
3200LB= 590ft/lbs tqact

[GilbertFlores]

^^+1 plus to much chatter lol

[GilbertFlores]

there ya go....i was looking for those numbers....i got the 3200 pressure plate. better in the long run for 80 bucks more

[alan678]

I have COUNTLESS amounts of launches on my clutch setup since I drag race her and after about 20k miles it is still holding like a champ...and BTW my car is Daily Driven too...as is 7 days out of the week O0

[rino]

same here about 20k on the clutch, no problems

[o-townFLA]

this is all good info...

as if you cant tell, Im in search of a new clutch before it goes. I already have the 3rd and 4th gear slippage...

[JDMboi]

i think i kniow what kind of clutch im goona get when my stock one goes out.....thamks for the info

[o-townFLA]

see we can have an informative thread.... O0

[o-townFLA]

well I bought a ACT HDSS with an streetlite fly. gunna be installed this Sat..

but i've been getting the best milage out of my car ever, reason being is that I cant go over 10 pounds of boost without it slippin...



holla

[JDMboi]

10 pounds damn lucky i want to boost 5

[MoReRyCe]

i had mine for 10k miles... and it broke... had 400awhp and like 340 tq never once launched it... but did a few track days... pretty lame... it uses an exedy hub so that might be why.. lol

[JDMboi]

^^^^ i passed by the parts store this morning but i didnt get off cuz none of the evos were there

So did it last you 10K or 40K?Â* :? In the thread below (4th post down) you said "my act lasted me like 40k miles till it broke from stress..."

http://www.socalevo.net/index.php?option=com_smf&Itemid=37&topic=60474.0

FWIW it's been over 2 years since we started making our own disc because we were having problems with hubs and the springs coming loose on the discs. Our current disc use a dual damper spring design and the springs are yellow, the older Exedy hubs weren't.

[MoReRyCe]

my bad.. its supposed to be 10.. well in reality 12k but i wanted to sound more dramatic.. :)

[MoReRyCe]

and btw this happened this year to me.. and it still was a daiken ( exedy) hub that was used with the dual springs.. looks to me as if the hub cant handle the new springs.. i still have this clutch laying around since my distributor said he was going to talk to you guys... but nothing ever got resolved.. so i let everyone know wut happened..

Kinda offtopic, I've notice my clutch to be less grabby while reversing or getting out of neutral in to 1st gear. Is this Â*a sign of a worn clutch? Â*Thanks!

Unless your distributor sold you an old clutch disc with your kit or a sold you a stock Exedy disc then that would be the only way you would get the Daiken hub. Just so you know we have a 90 day warranty against manufacturers defects. Our current discs in the Evo kit looks like the ones pictured in the link with yellow springs.

http://www.advancedclutch.com/products/streetdiscs.aspx

I'm more than willing to "help you" provided there are no signs of obvious abuse that caused the failure. Send me a PM with your full "real" name and address and phone number and I'll issue you an RGA #. You'll then have to to ship it to us, our warranty dept. will take a look at it, test the parts (in the case of a pressure plate)Â* make a determination on what the cause of the failure was and I'll get back to you.

In the future when your distributor drops the ball on assisting you with a warranty claim the first person you need to let know what happened is the manufacturer who is ultimately the only person that can help you, no one on here that you've told this to can help you unless I stumble upon your post.Â* We have a sales and tech line that is open Mon - Fri from 7:45 am - 4:30 pm where we deal with tech questions and warranty issues. In addition you can PM me on here or over on evolutionm.

[MoReRyCe]

cool thanx.. i actually called tech at ACT and they said it was just too long ago and there was nothing they could do.. so i gave up on it.. if i can find the clutch disk in my garage ill om you with my info n see if u can help me out.. thanx

[MoReRyCe]

btw.. if those are the new disks i would love to get one.. n try it out again since i really did enjoy my street disk alot... any way of knowing who has new stock of these instead of the old ones?

[airforce1]

Hi. Can you explain further?

[MoReRyCe]

when you release the clutch pedal its prolly engaging really high and when the pedal is at the top it could still be applying prease to the slave cylinder causing it to not let the preasure plate fully engage..

wut you would have to do it get under the dash and adjust the pedal so it engages a little lower that way you know for sure its releasing all the preasure form the slave.

DOnt put it to low or else it might not disengage the clutch properly.

ways to adjust the clutch are available through evolutionm.net

plenty of write ups on it.

That's odd because we look at parts that are out of warranty all of the time but we will always let the end user know that past the 90 day period or without proof of purchase we are not obligated to do so. If the part is found to be truly a manufacturing defect we will replace the parts at no cost to you the end user.

Not sure about that one bro, some of the AcT components are actually made by Exedy (according to AL at dynoflash). also, for someone who's looking to buy the ACT, there have been numerous incidents of people reporting being locked out of 2nd when approaching 7,000 rpms. do a search on evom and you'll see. I have no reason to be biased as I am rocking the ACT myself and have personally experienced the 1->2 lockout. (i'm not the worlds greatest shifter but I'm quite confident in my ability to make that shift). Even warrtalon on evom has reported this same problem and as outspoken as he is, seems to be quite efficient with a gear box. I think i might be going with the full RRE package next time around

Considering the source who happens to be sponsored by Exedy (as is Warrtalon) you should take that with a grain of salt. The only thing made by Exedy in our Evo clutch kit is the part that is painted yellow (and that would be true for ANY clutch manufacturer because of the cost of tooling to produce the cover. On an Exedy clutch for a Mustang for example, they would buy a cover from Valeo the OE supplier) and the release bearing that they have patented.Â*

I have also never seen anyone report an incident of lockout below or approaching 7K, it is typically reported by people shifting in the 8500 rpm range. This is not to say that there aren't any but that's not the typical scenario. If you are still experiencing lockout Mike at RRE has a longstanding offer to have anyone with a misadjusted ACT clutch (the most common cause of the problem) to stop by and he will correct the problem. FWIW I used to get lockout on the stock clutch on my Evo until I had it adjusted. The only times I have ever seen a Evo clutch that could not be adjusted is because the disc was bent on installation or the disc and pressue plate became warped because the user slipped the clutch excessively.

There are lots of reasons why things happen along with lots of information on various forums. Some of the information is based on fact and some based on speculation and heresay. I would venture to say that we sell more single disc aftermarket clutches for the Evo than any other manufacturer and most of the people with them don't start threads to complain that the clutch is holding too much torque, lasts too long or shifts just like it should.Â* ;). Although I'm responding to your post, this is in no way shape or form an attempt to flame you.

[o-townFLA]

I can be happy to say that my ACT shifts like butter, has no lock-out and holds plenty of the torque and abuse. I've tracked the car several times and have had no issues. Maybe I have an odd ball clutch....

Of course not, and no offense taken at all. I'm well aware of how much hearsay and speculation goes on on internet forums. I'm no technician myself and thus I addressed everything I posted as what I've heard through other members. Seeing as how I got a standup response from the manufacturer, I'm happy to take back the misinformation in my previous post.

However one thing I'd like to point out is that I'm not making things up when it comes to other people complaining about the 7k lockout as well, i have spoken with members who share my experience and read several posts on evom about the same problem. I don't know how many of those cases is attributed to poor driving or clutch abuse. I don't have a vendetta against ACT. I'm not trying to say that all the single disk HDSS clutches are in some way faulty. I appreciate your stand up answer but I'm just letting you know that others do in fact share in my experience with your clutch. But I will take Mike up on the readjustment offer. I'm perfectly aware that itt could just be that my installer didn't get it right.

[rino]

I personally had the lock-out, but 30 minutes under the dash adjust the clutch pedal and it's been all good for about 40,000 miles.

[Saosin]

ive had my act 2900lb for about 11K miles almost 12K and its still holding good 1 canyon run and about 3-4launches lol i know not alotttt

[LiquidLife]

I have the XTSS, I need my xtreme pressure :twisted:

[pjb00stin]

is the XTSS that much harsher in engagement over the HDSS?How is it for daily driving?I know the peddle feel is slightly stiffer,but should i just go with the HDSS?thanks!

[Tech@ACT]

is the XTSS that much harsher in engagement over the HDSS?How is it for daily driving?I know the peddle feel is slightly stiffer,but should i just go with the HDSS?thanks!


Engagement is related to the friction surface, not the clamp load of the pressure plate. Therefore the XTSS has the same smooth engagement as our HDSS since they are using the same organic disc. A puck style will change the engagement from smooth and progressive to harsh and more of a on/off nature.

As far as what you should buy.....that depends on how much torque your car is making. The average user needs nothing more than the HDSS kit which is rated at 508 ft. lbs at the flywheel.

[LiquidLife]

Yeah, the xtreme pressure plate requires more pressure to push the peddle in, but the engagement should be the same, that is unless your leg is too weak to engage it smoothly, hahahaha.

[pjb00stin]

so its just rated to handle more torque?what makes it capable of handling more torque?I think ill go with the hdss,since I won't be making more than 400tq.

[LiquidLife]

the pressure plate putting more pressure against the disc so it takes more power to make it slip, and makes it harder to push the peddle in

[Tech@ACT]

the pressure plate putting more pressure against the disc so it takes more power to make it slip, and makes it harder to push the peddle in


Essentially. There are 3 ways to increase the ability of the clutch to hold more torque: increased pressure plate clamp load, use of a more agressive friction material (like the puck disc do) and increased surface area (the principle used to make twin disc clutches). The XT pressure plate has more clamp load than the HD unit so it is able to hold more torque using the same disc that the HD kit has.

[LiquidLife]

Yeah I thought he was referring to the deference between HD and XT.

[Tech@ACT]

Yeah I thought he was referring to the deference between HD and XT.


You were correct, I just went into more detailed explanation. Thanks for helping explain it though O0.

[LiquidLife]

Haha, u definetly don't need my help, if anything I need urs. :)

[atlvalet]

So I have a 6 speed, but I am going to get a 2.3 with a red in the future. I've seen Jon at TRE recommend not going over the 2900lbs. pressure plate, so with a combo like above would a HD PP with a sprung 6 puck be the best? I think I will over power the regular street disc with all that power. I got about 60,000 miles out of my first one, and have over 30,000 miles on my 2nd (so far).

[LiquidLife]

why not go over 2900, overkill with the 6 puc I'm guessing?

[atlvalet]

why not go over 2900, overkill with the 6 puc I'm guessing?

Jon at Team Rip Engineering says with the lower torque capacity that comes with the 6 speed that the 3200lbs. PP is pushing it. He says you don't want to go over the 2900lbs. PP. A clutch issue down the road is much better than a tranny issue. I may even go with a custom gearset in the 6 speed, because I'm stubborn and like the slick shifting along with the 6th for highway cruising :)

[LiquidLife]

wow poor 6 speed... Yet another issue I've never heard of til now, thanks for the info

The following is no knock against Jon (him and the owner of ACT are long time friends), so please don't take it as such.

If the strength of the transmission is in question any additional torque or shock transmitted through it whether it's from clamp load, higher coefficient of friction (by using a puck disc) or increased surface area (twin disc) will result in a broken transmission.

Like I said in my previous post in this thread there are a few ways to increase the torque capacity on a clutch each with its trade offs but the end result if engineered properly will result in the same outcome. You could put a twin cermettalic clutch in there and break your transmission, or put a single puck disc in the car and do the same. From the mileage listed on your previous and current clutch it sounds like you have a smooth non abusive technique. IMO that is more crucial to the transmission life than anything.

One the primary reasons we recommend a full face street disc over our puck style disc is the fact that that it will slip when overheated and possibly save a transmission vs. a puck style disc which is a lot more aggressive. In the last 8-10 years the lines between what is considered a street or race car has been blurred. As a result you see a lot of parts that are intended to be used for off road use being put on street cars.Â* The clamp load of the average twin disc used on the Evo is approx. 3000 lbs which is about the same as our HD pressure plate. Make no mistake though, the aggressive friction material used to allow these clutches to hold 600-650 ft. lbs of torque will still break your transmission if abused enough.

No conversation about clamp load can be had without considering the friction material used on the disc or discs. Clamp load alone won't break a transmission, however abuse, and really agressive friction material definitely will go along way towards doing so.Â*

[atlvalet]

Thanks for the input :)

And yes, I try and be easy on my transmission...I am just not sure about the street discs for my next level of power.

WHen I was at 300whp, I got 60,000 miles out of my ACT. Now that I am around 400whp, my ACT at 30,000 feels similar to how my previous one did at 60k. I just don't to see 30,000 miles go to 15,000 miles if that makes sense.

And thanks for mentioning the increased friction with the 6 puck, even if it's sprung :) I know there's no absolute answer...

[atlvalet]

wow poor 6 speed... Yet another issue I've never heard of til now, thanks for the info


Just to be clear, my 6 speed is perfectly ok...it's just I may want to put a custom (stronger) gearset in there with my next round of mods....like I said, I like the 6 speed :)

[o-townFLA]

its nice to see that your ACT lasted for 60k at that power...

It seems as if the ACT clutch and the lockout problem I'm experience is the most common issue on a list of these evo owners regrets

[Mike W]

No one in So Cal that has had it has not been able to adjust it away. Back then I made an open offer for anyone that had it to come by the shop and get it fixed. Three people took me up on it, three got their clutch adjusted and were on their way. If anyone does have this and it can not be adjusted, I will personally guarantee I can get it fixed.

The only regret should be not working with the retailer that sold them the clutch and not having it installed by or working with an EVO specialist regarding the problem.

If anyone in So Cal or can get their car to RRE that has this problem, contact me at [email protected]

No offense taken but I will say the following.


Me saying that I have never seen anyone report an incident of lock out below 7K is not quite the same as me saying that there has NEVER been a reported case of an Evo with lockout below 7K which your post seems to insinuate that I did by quoting me.Â* I also don't remember saying that you were the only person with that problem or that it was impossible that it happened.

As far as that thread goes, there seem to be other people in there with and without any issue with their ACT product, there also people on Evom with complaints of lock out on the stock clutch, and the Exedy twin disc. I read things on various forums all the time and the one thing I've learned is that very few people make threads bragging about how great stuff works, how they abused XYZ part and caused it to fail or how they had no clue (or their mechanic had no clue) about how to install XYZ and screwed it up. Lock out can occur from a mis adjusted or plain ol never adjusted clutch, a bent disc (hanging the tranny off the input shaft or a warped disc (from playing John Force too much).

I'll say that for as many of these Evo clutches we sell the problems that are truly manufacturing defects are relatively few. We've been in business for 15 years building clutches that have set records long before Evo's were around. Engineering a clutch for an Evo is not that different in principle from any other car. If our products weren't up to snuff we wouldn't be here. If you've attempted to adjust to no avail, take it to RRE and Mike will adjust. I will even offer to pay for the gas for you to go there. If you truly feel that it is defective pull it out of the car and send it to me and we'll take a look at it. Feel free to take me/RRE up on any of the offers proposed.

well see tech@act, my clutch was installed by a shop and had a problem with the clutch not fully releasin so the clutch disc was sent to you guys and u guys warrantied out the clutch disc, now im out of ur 90 day warranty n will most likely still have to buy a new clutch dependin on what this shop finds, but that disc was warrantied out within 500 miles of it being installed in the first place , and now 3k miles later and even worse then before...??? n im not even pushin crazy horsepower or torque im under 300hp i know that, and ive never launched my car since ive bought it, a little insight have you come across issues like this in the past, does it seem like possibly a broken clutch hub?

I'm not really follwing your story so feel free to correct me if I'm wrong. So let's see....you bought our clutch kit, had a problem with it disengaging and sent it in, we decided to warranty it and now you have a problem with disengagement again?

If the car has a disengagement problem the fix is the same as lock out, because when the car is locking you out at high rpm that is also a disengagement problem. The causes are the same as I mentioned before, bent disc - install error see my post above, warped disc - driver error and possibly a broken drive strap on the pressure plate casting. Without seeing the parts in question it's difficult to say what the cause is.

FWIW install error and driver error, can cause any properly functioning part to fail prematurely........even on a stock Evo. Some people can have a clutch for 60K and others need a new one every 6K. Just curious as to why you needed to install one of our units on a car that makes less than 300 hp by your estimation?

Sounds like a plan, keep in mind that driving around on a clutch that is not adjusted properly will cause premature wear to the clutch so I would have Mike look at it sooner than later. Please let us know the results of your visit to Mike.

It is looking like it is equally or more important _who_ installs your EVO clutch. Try to find a shop that isnt going to use your car to learn how to install an EVO clutch.

^ I bore witness to a clutch install at an un-named shop and it was horrific beyond description. Hammers, pry bars, etc, used at will . Two guys ramming it over and over trying too get the tranny in place.
