What clutch are you running

[Lonnie D]

What clutch is everyone running and what set up powerwise do you have? Are 6 pucks that tough on trannys?
Can you get used to driving with a 6 puck for DD purposes, like on hills?
I am looking for a good clutch that withstand around 300hp range but can also be reliable as well decent to drive.

thanks for any input!

[down_shift]

I have a Centerforce, exedy didnt have a ka app when I bought of I would have. Centerforce is as easy to drive as stock but a lot better bite. no complaints but then again Im not really pushing the limits power wise. Everything I hear says get an Exedy.

[shawn shawn]

I have a stage 4 competition clutch on a fairly stock KA. Its a six puck sprung but its fairly decent for a daily driver, unless you have a weak leg then it will chatter haha. It was easy enough for my GF to learn to drive a 5 speed on though. But after 2.5 years of drift events and atl traffic its still holding but about due for a new disk.

i love the stiff feel of the uprated preasure plate on a clutch that is only rated for 250ftlbs... :D

Ogura MZ-400 electromagnetic tooth clutch
(torque - 2950 ft/lbs)

"Clutch is designed for high torque small space environments where no slip is desired. Clutch can be used dry or in an oil bath. A zero backlash option is available. Zero drag torque when clutch is disengaged."

If your head isnt against the seat, it will give you wiplash. ive been to the hospital 3 times.

im about to upgrade to the MWC-600 Electromagnetic Multiple-Disk Clutch
(torque - 4425 ft/lbs)

Multiple disk clutches designed for high torque small environment. Clutches are designed to work in oil Multiple disks produce high torque in a compact design. Separate drive cup allows for easy connection to your gear or pulley. Special oil path grooves in the friction plastes allow for quick engagement and response time. Because clutches are used in oil lubrication they have excellent heat dissipation.

mainly for that better heat dissipation.

I wish I knew what clutch I had. I know I have a stiff ass PP tho.

How much did you get that clutch for and what site? The only one I found has prices listed in Yen. And it only has apps for the SR.

This might be a noob question but does the SR clutch work on the KA tranny?

Holy shit, have you really had to go to the hospital 3 times because of your clutch? I don't think I want a clutch that strong.

[homeslicej2]

I have a Competition clutch stage 1 (won't hold your power levels though) it's a 6-puck, kinda harsh engagement, holds well. Thing that bothers me though, is a lot of places sell this clutch I have (including NOPI) for the SR20 (which I also have), but the manufacturers website says that the clutch should not be used with power adders such as supercharges, turbos, or nitrous. If I were you, I get and exedy or ACT if you want a single disk.

[Lonnie D]

I guess I should rephrase what I am asking because I think what I posted was a little vague, but I kinda wanted to see what opinions would be leaving things a little open.

I have a 6 puck that I have only driven for a short period of time and I am still getting used to it and have been doing a some research. I have a few concerns about the clutch and I am debating on what I should do, keep the clutch or replace it with something else. My concerns are:
1. Will the clutch kill my transmission?
2. Do you eventually get used to clutch enough that I won't have to do e-brake takeoffs on hills.

Keep in mind that this is a daily driver so I want a clutch that I can drive normally but I also want it to be able to hold up for any track use. Primarily it will be a daily driver and I don't have any intentions on drifting. I thing I don't care for on the 6 puck is that it has such a small area of engagement.

we have heard some disappointing things with their CC single plate clutches. but their twin plate rocks.

i ll never go back to single plate on any of my cars i build.

the s13 silvia front end, with the ogura twin plate clutch is also a daily driver and a weekend warrior.

stock tranny and we dont baby that bastard child :)

[Lonnie D]

What is the engagement like on a twin plate and how stiff is the pedal?

[Broke240]

You should get use to the clutch enough to not have to use the e-brake.

I have an exedy stage 2 three puck, but it's almost done.

Got a OS Giken twin plate that I am just waiting to have enough time to install.

[tacos14]

xtd stage 2 clutch

[v-empire]

What is the engagement like on a twin plate and how stiff is the pedal?

we are not babies.

we have performance for breakfast and strong left calves for soccer... lol

i dunno, if i were to drive it on the streets, i would drive it. if i mind, i wouldnt. what difference does it make whether its stiff or not?

you want a strong pressure plate, its gonna be stiff.

ok, here are some tricks for you pedal stiffness junkies, if you havent already know........

you can actually get more tension on the pressure plates and less pedal pressure by upgrading your MC, changing you TOB size, upgrading/modifying your slave cylinder, or lastly modifying your pedals for more pivot movement.

ok, hope that helps.


and ..............buy a twin plate.
and never have to worry about it.
upgrade everything else from there.

:)

I don't care if it is stiff I am just curious thats all. I don't care if the clutch is not like a stock clutch, I just feel like an ass driving the 6 puck and stalling out every once in a while, but I guess I will just eventually get used to it. I was just curious of the differences in application and whether or not I will be able do get used to the 6 puck.

[v-empire]

of course you will get used to it.
???

we are human beings.....

we will get use to it.

lol...... no worries.

its not the 6 puck that makes it stiff, it the pressure plate.
6 puck is a little more agressive on the grab.

you will stop stalling in less than a day of normal driving.

Metallic Puck Style Clutch Discs

They wont die. They can take a ton of abuse and wont turn into kitty hair. Even when they get so hot that the pressure plate warps and the diaphragm looses it's spring pressure, they wont fully die. Cool, right? The down side of that "never dieing" is that it allows them to keep slipping, then heat up and grab. The slipping with out dieing makes the surface cracks in the flywheel and pressure plate that will eventually cause the flywheel to come apart. Whether it is a stock flywheel, lightened stock flywheel or a Chromoly flywheel, puck clutches make cracks that kill flywheels, that kill bell housings and more. They have their place but I don't think in a street car. In a race car that gets regular inspections they can be fine. Also most puck clutches have a solid hub center that will contribute to horrible coast down gear noise (worse in an AWD).

Puck style disc
http://www.roadraceengineering.com/eclipsetech/clutch/6pucksprunghub_small.gif

Puck style discs can put up with a lot of heat. You also need to slip them more to keep from breaking things. More heat made. When a street disc is slipped too much and gets hot, it disintegrates and turns into kitty hair. You wont keep driving on an overheated street disc. If you get a puck disc to the same temp, nothing happens. That's nice because you can keep racing. But that heat is hell on the flywheel. Just like brake rotors crack when over heated, so do flywheels.
If you keep racing on a cracked flywheel, you will eventually saw your tranny in half. It does not matter if it is a lightened or stock flywheel. We get flywheels sent in to us regularly that are too cracked to use. Those guys cry like babies when they have to pay a core charge. From the cores we get, I would guess one out of ten racers are driving around with some cracking.

[JJ Alfano]

excellent write-up

i have exedy stage 1 clutch disc with competition pressure plate, to the best of my knowledge. that combo could be backwards though.

[down_shift]

http://www.pdm-racing.com/products/imag/centerforce3_small.jpg

my centerforce street style disc started slipping really bad early on at private day. like 3 runs in it felt like I was going from 1st to 4th. Had it about 15 months and gave it a pretty rough break in which probably didnt help. So now I need to see about a replacment disc or maybe even a new clutch all together.

[v-empire]

bryon. i may have access to a used ogura clutch which is a hyper single or a blitz(also ogura) twin plate with hyper single clutch, which you can upgrade to a twin if you want. its the interchangeable setup.

i rather someone who can appreciate it, have it. let me know and i ll see if its still available.

cost is probably more than half of whats it is new.

You'll be fine. I have a 3 puck in my daily ;).

I get a decent amount of coat down noise in my awd with a 3 puck... Not too bad but it's there...
