I dont think so. My ACT never drove like the SBC did. My Clutchmasters drives more like the ACT did.

hmmmm...maybe you were on the non-mod 5X at the time.

i dunno. either way we'll find out when i bolt on some sticky rubber

^ Do it! Lets see some 11s!

**NoisufnoC** · 10-07-2008, 12:35 AM

That being said, the feramic would heat up more because of the "increased" driveability.

Just my theory but my SAME exact model clutch I had in my car, is this same exact clutch that exploded. Mine was slipping like no other, yet drove great as a DD. I mean great. That 6 puck drove like a full face disc and to me, that's entirely too much "slippage" for a 6 puck. Just couldn't hold at the track.

So you had your clutch explode also? I don't think I understand you. Sorry. Was it a modular stage 5 or a non Modular stage 5.
How much damage was there?

Thanks

no, he had issuse with clutches slipping. no explosion.

You lost me here... the clutch in the pic was using a stock style flywheel. It's modular.

After some reading, Feramic is a blend of Ferrous Metal and Ceramic.

Quote:

Feramic has the highest heat resistance of any other clutch material made today with a coefficient of 0.7. This coefficient doesn't change with temperature as many clutches do until after 900 degrees and has a melting point of 1600 degrees to tolerate even the most extreme use.

None of those statements came from SBC, just from some basic Google research

I cant find any info on what makes up cerametallic

**NoisufnoC** · 10-07-2008, 11:21 AM

clutchmasters fx400 uses ceramic pucks
ACT street disk is organic material

i cant find what ACT 6 pucks use

Yeah you're right. I thought it was a fidanza flywheel. The outer edges looked like it....then I saw that stock dust cover at the top of the pick. Disregard any statements I've made about non-modular clutches then. So to straighten things up, I've never heard of non-modular clutches exploding.

My clutch didn't explode, it was non-modular. It just slipped right away and wouldn't grab.

I was told by ACT's owner, Dirk, that the 6 puck material is ceramic, just like CM's 6-puck.

As far as feramic goes, it may have the highest heat resistance but I just know that my own personal experience the 6-puck feramic (SBC) didn't bite no where near as hard as a 6-puck ceramic (CM & ACT)

Sorry to confuse you. Mine didn't explode. It just failed at holding the power my car was giving out. I had a non-modular Stage "5x" w/Fidanza flywheel.

Interesting...

tavenger5 · 10-07-2008, 01:38 PM

Mine is slipping - stage 5 non-modular - already have a stage 5 race ready to go in

I'm convinced no matter what clutch you get in this car, it's going to overheat and start slipping at some point - either that or your 3/4 synch is going to take a poop.
