Clutch, again

[ZX2guy19]

I really do apologize for all the questions. But I'd rather have EP call me a noob then retaking out my motor.

I was referred to a site by a fellow ZXtuner for some clutches. They are high hp custom clutches. Can you guys tell me what you think of this stuff?

Pressure Plate

What do you guys think? Is this good for 300whp?

[CT9A]

Its tough to say....The pressure plate you posted says its only a 25-55% holding capacity increase, and the disc doesn't say anything about its capacity. I don't even see where it says what its friction material is. I highly doubt it will hold. You get what you pay for when it comes to performance parts....Clutches especially. You can get it and try, but you will most likely waste your money. 300whp is a lot to ask out of any zx2 clutch. Thats right around the limit of a spec stage 3, and the only street-able clutches made(that i know of) that are stronger then the spec3 are the 3+, unorthodox ceramic and feramic 6 pucks(both are very expensive), Clutch masters stage 4 6puck(also expensive), and spec4(spec 4 would really be pushing daily driveability)

I think SPEC is gonna end up being the best clutch for the money. If you have to, save some extra cash and splurge for the one you KNOW will handle it.

Clutches are torque rated and not HP rated also.

[jeffescortlx]

I dont know why you guy's are so in love with Spec. Over at FEOA.net we've had about a 95% fail rate with Spec puck disc's. I've been through Clutchmasters, Spec stage one and 3, and a Southbend stage one and clutchnet 4 puck. So far the clutchnet is the only one that has held the power, and almost no chatter. All the Spec did for me was slip and chatter when the boost came on, happened to many others to. One guy had the spug hub fall apart.
The clutchnet also has the hub springs fully enclosed in the plate, plus is was the cheaper then the spec. I will never buy another Spec puck disc.

[CT9A]

We like them because they work. I have seen very few spec clutches fail completely. Even if they do slip they are just glazed and you can just drive around easy for awhile and they are back to working fine. There was a time a few years ago that a couple guys had problems with the springs coming out, but I have seen nothing of that for 2+ years. And to the remark about not buying a spec puck clutch....I've tried to tell zx2guy twice to buy the 3+ which is a full metallic disc that is far stronger then the standard spec3 6 puck, but he says he can't afford it. The Spec 3 will be right at its limit at that power level, but it should be fine as long as he doesn't try to go any higher, or drive the crap out of it all the time. You do what you want zx2guy, but If you do decide to go with the clutchnet. Atleast contact them and find out if they think that it will be able to support the power you want.

Clutchnet makes quality stuff. You'll probably want driveability as close to stock as you can get unless this is purely a track car, and Clutchnet is civil on the street. I've always been a fan of ACT and loved the street disc in my Z. You'd probably want their 6 puck sprung disc.

[ZX2guy19]

I can afford the Spec Stage 3+, but I heard at 350whp, it won't hold. I will be near that now and definitely higher than that later.


So davey, clutchnet will be ok?

[CT9A]

No metallic 6 puck will hold that....You will need a ceramic or feramic disc. You need to make up your mind on how much power you going to make....First time you asked this it was 275...then it was 300 and now its 350+.

[ZX2guy19]

Right now it will be 300whp. In the future I will be doing the mtx-75 swap and obviously I'll look into focus clutches then. So for right now, it will only be 300whp.

[jeffescortlx]

I'd think clutchnet 6 puck sprung with there med or high pressure P.P. will give the best street feel and still hold the power.

My clutchnet chatter is waaay better then the Spec, there's hardly any at all. With a 6 puck it will be even better.
My 4 puck clutchnet is holding about 300ftlbs @ the flywheel. But keep in mind since I have the 1.9 tranny my disc is 1" smaller in diameter then the DOHC clutch. So the larger 6 puck should have no problem with 300-350.

[ZX2guy19]

Why the hell are they so cheap? Lol

How much better is a 4 puck compared to a 6 puck with power and how much worse for driving?

[jeffescortlx]

Why the hell are they so cheap? Lol
They sell the clutch kit part by part, so if you want an alinment tool or T.O. bearing you have to pay for that extra. And when you order from clutchnet.com your ordering right from the manufacture, no middle man.

Cant help you there, all I've ever had is 4 puck's. But I drive that in traffic in town just fine.

[daveyfx]

I would think with a 6 puck Clutchnet you might not have any chatter, except maybe some when the disc is not warmed up. If it were me, I would try the 6 puck sprung hub with the 3X pressure plate. You should get smooth engagement and plenty of holding capacity.

[daveyfx]

Also, if you contact Clutchnet, they will be able to provide you with exact torque holding figures of their pressure plates. I no longer have the information but I want to say that the red 2X might be enough for your needs. On vehicles that have a higher stock output, the 3X would probably be too stiff. With the ZX2 being as anemic as it is, daily driving might be fine.

[ZX2guy19]

Awesome. Still under $300 for a new clutch. That's sweet as hell.

Davey, do you recommend 4 or 6 puck. I know you keep saying 6 will work, but I need almost 100% sure will work.

[jeffescortlx]

I have a feeling that with a 6 puck and high clamp PP you'll spin your tires before the clutch will slip. Unless you plan on running slick's, in that case I bet you'll have more problems with exsploding diff's rather then a slipping clutch.

[ZX2guy19]

So go with a 6 puck sprung and high clamp PP?

I plan on running some kind of drag radials. I won't launch it hard though, maybe 2.5k rpms.

You're either going to spin your tires or break your diff. Some people like to have their clutch be the "fuse" in their drivetrain.

FWIW I have a Spec Stage 3 6 puck and its never slipped on me. Ive had my clutch out a few times and it still looks like new. They had problems in the past but it seems like they fixed them.

For now I would get the most streetable clutch that will still hold the power until you get a MTX75. On the street you're going to spin and if you launch on DR's you're probably going to break something.



Ps: Noob!

[ZX2guy19]

Yes but the spec stage 3 is $100 more than the clutchnet.

I probably wont even take this thing to the track until it has an MTX-75 for fear of breaking an axle or stripping a gear. I think my street tires will do fine from a roll and it'll look great for show.

PS...I knew it was coming, lol.

[smooth]

when i get home...i'm looking at the spec stage 3+ mainly because it's a solid disk and streetability plus all the holding power i need.
