I have a question for those who use or have used a 6 puck clutch or similar. When I start to drop the clutch slowly in first gear giving very little gas the car shakes kinda heavily. And it seems to be a heavy transfer of power form the fly wheel to the wheels themselves with this clutch becasue it is such a high power capacity clutch. My car is pretty much stock except for the intake a DP, CB, and higher flow fuel pump.

Never leave it halfway, just let go of the clutch, the clutch can't slip well. The shaking you feel is the clutch jump and grab on the flywheel.

^True, as well you may want to jack the car up and see what the condition of the PPF is. With the added torque transfer of the 6 puck( or grabbing force) the PPF doesn't like it too much.

When i bought my 94 it had a 6 puck in it and shook like a 9.0 quake! The PPF was being held on by sheer luck, it was craked all the way thru at the rear

Wow, well how the hell do I break it in with street driving for 475 miles by dropping it? My engine is practically stock. Like I've said in a former post I wasnt supposed to get this but they sent to me. Should I get a mazda speed PPF then? Becasue it feels like the entire god damn car is gunna explode. I'm afriad my drive shaft or freakin LSD is gunan just bust under all the intense power transfer....Is it possible to damage the drive shaft or LSD with that much power transfer from so little hp and shaking? All I want to really know can it screw anything else up?

I dont think these types of clutches have a "break in" period.

Why do you have a 6 puck clutch in a nearly stock car? I would've sent it back for the one you needed to begin with. Talk about overkill...

But you do not need a new MS PPF. Just remove your old one and weld it to be stronger than stock.

Or just have one built by someone with some good tube welding skills.

the 6 puck is entirely inappropriate for anything but a 400+ rwhp car. ditch it asap before you break a whole bunch of driveline parts and then ditch it.

I do not have one on my car but I have friends that do. I have learned that with the 6 puck and once that are like it there is not a half way point. You just have to let it go. They are not made to have a smooth transition. They are made to grip and grip ver well. I will be going to a 6 puck or something along the lines of one when I get to that point. I may just go with a dog box. It is still up in air. As for what everyone else is saying about getting rid of it, get a stock clutch man. I think that my old one is in good shape if you are interested in a used one for cheap. Car only had 57k on her.

agreed, i have a 6 puck in my car when i bought it and I jus have bolt ons and i've been driving my car for almost a yr now everyday and let me tell u, it sucks hehe i'm glad the clutch is finally going out

AntiVenom7

how's that RB sprung 6-puck? Does that help smoother engagement?

Xeros

Yeah I was suspposed to get an exedy sport kit at first. It was on back order for 2 weeks so RX7store said they would send me a 4 puck and they said it would be fine. To my surpirse when I got it, they had sent me a 6 puck. I didnt question it. I just figured screw it I'll probably need it later on anyways because the power will be uped. Bah... I really do not feel liek going through all that to put a old clutch back on which I threw out becasue It was usless form the last owner. I guess I'll just have to quickly make this car 400hp aye? haha. Kiddin.

I had an ACT 6 Puck clutch on my fc and I drove it everyday on the street.. it wasn't nearly as horrible as what you are making it sound as.. just have to let the clutch out slower. If I didnt give it enough gas the entire car would shake horribly but that was just corrected by a little more throttle.

Sprung or unsprung 6-puck?

(i.e. does it have springs anywhere on it)

Jason93RX7R1

Same reason clayne is asking above...

It will make a really really big difference if it is a sprung hub clutch or a solid hub clutch. I will bet you that you were supposed to get a 4-puck sprung hub and got a 6-puck solid. That is going to really really suck long term, especially if it is your daily driver.

You should have called Jason and questioned why you got a 6-puck... .

I got my 4-puck sprung hub Spec clutch from him and it was awesome. All the holding of the puck clutches and hardly any chatter whatsoever. I'd get it and R&R your 6-puck.

Xeros

Well I cant exactly return it now that it has like 230 miles or so on it. Its not exactly my daily driver and it really isnt as bad as it sounds liek Cloead said. I was just wondering if it will cause any seriouse damage to the drivetrain in the long run? Becasue it doesnt shake as bad with a tad bit more throttle and I like knowing its a very straight forward minimal power loss transfer of power, personally.

cloead

Mine was 6 puck unsprung. I loved it myself, I went to the strip a lot and it held up to a million 5k slips and held great. It was fine for street driving, just took getting used to, never bothered me at all.

birdy01

yea my clutch was a 6 puck unsprung as well. went to the track 25-30 times and launched great

dubulup

you'll get use to it, and it will drive like normal. Just don't let a girl drive your car.

clayne

Sell the unsprung clutch and get a sprung one. If you don't do it - your driveline will be sorry (u-joints, motor mounts, etc.).

BTW: Hi Jason, haven't seen you in a while.

I have a act 6 puck in my t78 rx7. It grabs like hell, but i just dont think i can really justify trying to daily drive this clutch. Its not as bad as people are making it out to be, but it is pretty ruff. Im comptletely used to the clutch, since ive had it in my car since it was near stock (1.5 years or so now). In the earlier days of owning the clutch, it was was suggested to me to start releasing the clutch at around 2500 rpm to avoid a ruff start. It works well but i dont know how good it is for the clutch.

On another note, i feel this clutch is very well made, It has handled a rediculous amount of abuse and still holds rock solid.

I had a worn ACT unsprung 6-puck in my TII, and I didnt even know it until I did a clutch job. I replaced it with the Street/Strip solid sprung clutch, which holds up to 350lbs/ft of torque or something.

6-puck discs arent as bad as people say, but it can cause more strain on the driveline.

What He Said^

Aight well it seems to be getting more positive response then negative except for clayne's note...which is what worries me. I'll just let it drop at 2500 from now on and get used to it. Would putting a brace on the tranny and the LSD possibly help against any damage or strain caused by the clutch? Maybe even a engine tourge brace to help out the motor mounts or is it all pointless? And a lot of you guys are talking about drag racing which isnt something I am into at all truth be told. No offense. This car is being built mainly for Auto X, track and mayeba drift event or two on the side. Is it really the proper clutch fo r this use? I figure it is since it transfers power so well in each shift?

clayne

Either clutch slips or it doesn't. That's all you need. If you're at a low enough power level, a high performance clutch is overkill. One of the other advantages of the more hardcore clutches is that they usually have a shorter actuation distance - i.e. does not take much pedal to engage/disengage.

Now, if you have to drop from 2500 rpm to leave from a stop - it's not a daily driver clutch.

I have the Pineapple sprung 6-puck on my FD and I'm letting it engage around 1200-1500 rpm max. You have to have a smooth handoff of clutch to throttle and just give it throttle when it feels like its bogging.
