you get one popular guy to say he thinks something is great and people follow him and preach what he says. i drove an exedy twin in a sti and driveability wasnt noticeably better than the act xtss i had in my sti. my act didnt make a pile of noises or shudder either. overrated imo.

 

I second that. The issue with rpm hang didnt help the ACT either. Ive only run ACT clutches in all my old dsms and in my evo. It came with a Spec clutch when I bought it which was also very tough and an under rated clutch IMO.

 

If we've now shifted to a drivability pissing contest, it's been MY personal experience that the Exedy Twin HD (not the regular Twin) was one of the better driving, BEST shifting clutches I've ever had in my and customer's Evos. Whereas my experience with the ACT units in Evos were not the best for fast shifting/racing/downshifting etc. In the defense of the ACT clutches, the Exedy units have much more centralized mass which would naturally support such activities. Even thought the Exedy Twins HDs are not "lightweight" per se, they carry that weight better than any single built off an OE housing (almost all of them). So in that vein, it's an apples to oranges comparison. Then you get further into variables of the different flywheels that can be run with the singles where the Exedy twins are fixed.

There are some good singles out there, myself already expressing my OPINION on two of the better ones. One of which I still personally run and like. I believe most people who daily drive their Evos would be happier with a good single/flywheel setup than a twin. However, after my personal experience, no one will convince me that these singles will perform better than an Exedy Twin HD when it comes to laying down the law on the tarmac. I don't miss the rattles of my HD Twin sleeping in my attic at home, but when I'm hot rodding around/racing, I miss the hell out of the shifts/downshifts etc.

In short, anyone telling YOU that YOU will get this or that with a clutch is a bit full of themselves as they do not have a FREAKIN' clue what YOU will subject a clutch to in it's lifetime with YOUR driving habits. They will have ZERO idea of whether it was installed correctly, or tweaked. So take EVERYONE's advise including my own with a grain of salt. It's like a box of chocolates... or was it opinions are like xxxholes... everyone has one, and they...

 

if the price was somewhat close, i would choose a triple or twin instead of an act, but $2,000+ is just absurd for a wear item like a clutch to me. im not drag racing all the time, i just need a clutch that will hold the power and shift decent beating around on the street.

 

Sounds like the perfect reason to get one of the better singles...

 

i have a ttp special act (HDTTP). they claim it will hold 655 wtq and shift fine at high rpm. im skeptical, but will try it with an open mind. i hope it works like they say it will. the couple reviews i saw were good, but they were much lower power than what ill be at.

 

I'm in the same boat...my exedy twin is slipping and I'm not sure if I want to rebuild it or just buy a different clutch,or maybe just buy a new exedy and rebuild the first as a backup.....The one thing I like about the exedy is how smooth it gos in and out of gear,I don't think a single will be this smooth but then again I haven't driven a evo with any other clutch...decisions decisions!!

 

i drove a act 6 puck sprung hub actaully raced it and i thought the shifts were fast for this particular car it launched very smooth and i was no lift ****ing the p*** out of the car and it did not miss a beat. i have a exedy twin and i love that clutch also very nice engagement and i got a lot of miles off of it. they are both very nice clutches i am not selling my twin that needs to be rebuild but only new discs and has a brand new retaining clip i upgrading that can hold more tq.

 

That's the one I'm currently running; not sure that there is any difference between "TTP Spec" and a standard sprung 6-puck from ACT. My best guess is that they are the same. I've had no issues holding the power or shifting at +8K RPMs on my setup. I have mine mated to a RRE lightweight flywheel as well.

 

Your ACT holds the numbers in your sig ? 617whp / 517wtq ...

A LOT of shops are telling me the exedy twin will not hold much power and are trying to sell me a triple which is out of my price range....For the guys that have actually had or drove a exedy twin and a ACT..How different are they when shifting and going in and out of gear ? I need to buy a clutch in the next few days and im reading and doing research like crazy but im still unsure which clutch to go with...

I was originally going to rebuild the clutch but im leary on that as the clutch is still in the car and i dont know how much damage it has Nor do i know if it will last...So im thinking of going New instead...Any help would be appreciated!!

Need a clutch that will last/hold in the 500-600whp range..And DD "friendly" if possible..

 

Correct, numbers in my sig. I had the 6-puck in my garage for the longest time and had it installed when I built the engine. I used to have the ACT HD street disk that lasted me a while in the 500whp range. I didn't launch the car very much, but it held up for over 20k miles. The new clutch is a little harsher, but still very streetable. If you're on a budget the 6-puck will be fine for your power levels. I believe TurboTrix ran 9's on that clutch way back in the day. I'm holding out for the revised QuarterMaster if this 6-puck dies on me.

 

I have about 1500 miles on my ACT HD 6 puck spring. Pedal feel is perfect. It is about as soft as stock but much more responsive. 7800rpm shifts, never had lock out, even hot at the autox course. Driveability is great in my opinion, little harsher but it is a 6 puck. After install i can say i am definitely an advocate for this clutch, it far exceeded my expectations.

 

Which flywheel are you running with it?
Any signs of "throttle off " rattling? Thanks!!

 

I used to have real bad throttle hang with my Compeition Clutch Carbon street disc, i recently installed my Exedy Twin HD. I BARLEY hear any clutch noises (with radio on @ 1 you wont hear it) and it shifts perfectly. Clutch already engages smoother than most other clutches I have driven with.

For those that get a lot of chatter/shakiness, i'd reccommend you pick up a Blox or beatrush front engine roll stop. I 99% eliminated any kind of chatter issues with that one $70 mount. Shifting and everything improved as well, great mod to do with a clutch swap either single or twin disc.

 

I had a 6-Puck, loved it although it made a LOT of noise under deceleration. I could slip it no problem, it was on my DSM.


The TWIN disk is nice but does not hold the power of a 6-puck and they are SO expensive. They are nicer to drive.
