Stock Clutch

[SirSpectre]

Quick and dirty question:

What is the stock clutch rated for power wise? At what level should I begin to worry? Aiming for 260 - 270 whp.

[cdrazic93]

Thats about when the clutch will slip. Around 210-220 wtq.

[SirSpectre]

Thats what I thought!

Clutch kit is added to the build list then.

I've been look around and researching this. Everyone seems to like the ACT kit. Price is great, reviews are great, but I don't want a light weight flywheel. I'll be putting a turbo on in a few weeks, so I'd like to keep that mass up (already have a LW driveshaft), and I hate flywheel chatter.

Any recommendations on a good clutch kit that uses stock flywheel and can hold some torque?

[boredom.is.me]

It can definitely handle more than that. It shouldn't be a concern until the 300whp mark, which I believe would be about 240-250wtq. There are plenty of turbos and supers made to do well with the stock clutch, and they are definitely pushing more than 260whp.

It might be a concern if you are running crazy grippy and wide tires, but not with stock equivalents.

Not wide. 225 wide. So 10 over stock. I still have stock tires on now, but tires are on my list as well. Nothing crazy, but better than stock. I plan on having a bit of fun with it, so I was thinking that It may be something to do now anyway, since more power is a few clicks away. Peace of mind n all that.

I found 2 that seem interesting:

Competition stage 3. 12.8 lb fly wheel. Heaviest LW flywheel I could find.
Spec stage 3+ Never heard of them. Not sure I trust.

Here in Aus Exedy do heavy duty clutches that will bolt to the stock flywheel. Can you not get the same kits there?

(screen grab for proof and part numbers)

[SirSpectre]

Yeah there is that one. I dont know how i like the idea of a 3 puck clutch. Just seems....unreliable? I'd prefer full surface.

I guess a flywheel wouldn't be terrible if the chatter was non-existent.

Anyone have any sound clips of Flywheel/driveline chatter?

[SirSpectre]

Decided on Competition Stage 3 with 12.8 lb flywheel. We'll see how it does.

I ran a spec clutch in my old supercharged mustang. They were pretty well known in the s197 community. The 3+ had a light pedal feel as well and was really grabby. Not sure how that translates in the zn6.

I just installed the Comp Stage 3 segmented clutch and a SS clutch line.

Pedal feel is awesome now. Perfectly feel when the clutch releases/engages. The clutch is super grabby when cold. I am still struggling with it a little. When its warmed up a bit more its much more manageable but still just as strong. A little chatter under low RPM high load, but I also installed the DSS 1 piece drive shaft, and the Megan racing trans mount. Little bit of vibration. Loving it so far. Highly recommended.
