A good 400hp clutch.

[50trimgst]

I know this thread has been answerd time and time again. Tho it seems that the answers are changing. I used to think act was a good company but 1000 miles later not so much. I have done some research on this in some old threads and everyone has some hooror story. I was over on another forum and there was several race shops including Dave Busher himself said that act is going down hill and will no longer sell there product. Some recommend fidanza and Exedy. But there is several post on here saying fidanza clutch disk break and springs come out. Also they can't take heat very well. I have herd good things abought south bend but not a whole lot. So I was wondering what people on here are running now that times have changed and mostly everyone on here is making over 400 whp or atleast shooting for it. Is anyone mixing and matching Pp and clutch disk. Also I've herd good things abought twin disk but most people are only getting 15,000 on a twin disk setup that cost 3 times as much as a regular clutch.

I'm running a Fidanza 4.3 setup just fine.

 

[50trimgst]

I was realy interested in this setup untill I read the fidanza clutch post yes I know it's old but have they improved there product. Also what kind of driving are you doing any launches

 

[LiquidX]

I drive it hard at times but I do not launch the car. I'd prefer not to take a risk of breaking axles on the street

I don't really care what is said. My act2600 has been in this car for 3 years and I'm making right around 500whp now and I've launched it a few times. For pure performance though its all about a twin disc.

I too am running a fidanza 4.3 6 puck sprung and there lightweight flywheel. I like it and haven't had any issues yet.

Have you put many miles on it. Everyone I have talked to says they run into problems between 12,000 15,000 with just spirited driving and no launches. Also what kind off numbers you think your making? I'm realy looking forward to going to a holset and breaking the 400whp mark.

By what research I've done act has gone down hill with in the last 2 years. That's why I'm bringing this up again. The act 2100 breaking may have been my fault I was rung the g50 at 25-28 psi on a fwd so maybe I was making to much power for it. I'm just trying to get some new opinions on new products and if anyone else thinks act has a quality issue.

Mine has been in my car for a few years and seen a fair share of launches and it doesn't slip and still grabs great. around 12-15k miles on mine

Although for pure performance, a TwinDisc is the way to go.

You actually stand a much greater chance of breaking driveline parts at the track, where the tarmac is so sticky you can literally walk out of your shoes if they're not tied. On the street, you'll just spin.

Personally I think you should launch every time you pull out.

Its not the horsepower number that kills clutches, its the torque output. You might hear bad things about ACT but I have nothing but good things to say about my ACT 2600/street disc setup. I've been running/launching and DD'ing on mine for 2 years now with roughly 20k on it and it still looked great when I took it off last month to do some R&D for a Comp Clutch.

ACT is just up the street from us here in SoCal and their reps LOVE the DSM community because of how many of us run their clutches because of how well they perform. ACT rates and advertises their clutches to hold 70% of what it can actually hold that way tuners don't buy a brand new setup and burn it up in a few months. For example, a ACT 2900/street disc combo is rated to hold 595 ft/lbs from ACT but thats only 70% of where it would actually start to slip... around 850 ft/lbs. Most clutch manufacturers advertise the MAX or 100% of what their clutch can handle, as I soon found out running that Comp Clutch rated to 400 ft/lbs tq.

If 400 ft/lbs of torque is what your expecting the ACT2600/street disc combo will be plenty sturdy enough to hold the power. But like Justin mentioned, if you hook at the track (don't lose traction) your clutch will hold but your stock transmission won't. Being a FWD platform I think I'm safe to say that unless your running QTP's you won't have a problem breaking the tires loose with 400 ft/lbs of torque.

Another vote for ACT 2600. They just work so damn good for the money!

 

[yepes281]

XTD stage 3 ftw!!!

 

[SBR Joe]

Ive run ACT 6 puck kits for years, not one problem since they redesigned them.

Top dog is the ACT twin, kick ass for high HP, but with forgiving friction materials for DD cars. Thats my next clutch upgrade for my 1g AWD for damn sure.

Unfortunately for you, youre limited with FWD. Clutch masters sells a good streetable twin disc setup...but honestly, my number 1 reccomendation for you, is the ACT 2600 with the un sprung street disc. Good engagement, quick shifting, and no stupid springs to break!

I share the same mindset.

 

[50trimgst]

It wasn't just what I was hearing. I broke a act 2100 with only 25psi from a g50. Also around 7500 it was very hard to slam gears and I've seen a 2600 do the same.

thats why i suggested the solid hub street disc. No springs to break, and no lock out in higher RPMS.

I can no lift shift from a launch, my 2600 with solid hub disc, on a stock 92 transmission, no grinds or hang ups at all shifting at 7800.

 

[jestoy7]

I agree with Gofer, the ACT 2600 is the most common for that hp. That's plenty clutch for that hp range and Marti has a good price on them today.

I've been running an ACT 2600 for almost 2 years with a Shepherd tranny and it has held up fine and I am at around 550 whp. Buschur has done alot of work for me and I know he doesn't like ACT clutches, i think he had a bad experience with one, but I know alot of people that have had no problems with ACT. I got my trans built a few years ago by Shepherd and he himself recommended the ACT 2600. I say they are good clutches if installed correctly, if not go with a twin disk exedy.

On that note i had a favorite stop sign out in armburst PA i used to launch at everyday on my way home from work in Greensburg.

I have been running an act2600 for about 2 years. I never once had a problem with it holding power. I just could not get the thing to take a high shift.

I have a shep stage 2
shimmed pivot ball
ss clutch line
6 puck unspring (love that)
fidanza fw
oem slave and master

With no lift to shift i could not get a better shift then 7200 rpm.

Im trying the south bend carbon kevlar an see how that holds up.

One concern i have for 50trimgst is he going to have the dreaded C word problems with a 2600 being he is a 95-97 seven bolt?

 

[richard33]

im another one with an ACT 2600 with a 6 puck sprung disk. My stock tranny shifts at 8.5-9k like butter I made 500+ whp

 

[spadepro22]

Ive been hearing that the sprung disk from act arent what they used to be. For the guys that are breaking them, are you breaking them at the track or what? Im starting to lean toward the south bend.

 

[lumberjackracing]

I run an act2600 and love it. My two step is at 6300rpm and it holds strong but on a couple occasions I have had high rpm shift problems.

What kind of disk?

 

[lumberjackracing]

A sprung 6 puck

 

[KYNgsx]

My old setup was an ACT 2600 and a sprung street disk. Got it slightly used out of a FWD. It did 3 years of street driving and racing on the track and took lots of abuse. Probably several hundred 6500 rpm two-step launches in that time and shifts on the track were at 8000 rpm.

When I took my car apart for a complete overhaul, the clutch still looked great. The friction material was worn down almost even with the grooves so it was near the end of its service life, but otherwise the clutch was in great shape. It wasn't shredded, it wore evenly, no hotspots on the flywheel, and all springs were intact. The only thing I didn't like about this clutch was the heavy pedal pressure; went with twin disk for my new setup.
