All this happened @ 11psi boost and 364rwhp on the dyno..... rolling into it, so no shock.... centerforce SUCKS

Damn....

Your FC? When did this happen?

Not my FC, customer, fellow member, and friends car... 2gslse... his 13B-RE w/an ApexiRX6 turbo kit, VMIC, Haltech PS1000 etc etc.... ACT HD/SS installed already, just got a few things to button up and we'll be back on the dyno.... whenever the shop gets power back anyway...

DAYUM! Looks like the clutch friction material is just riveted to the disk - I can't tell from the picture, but was there also an adhesive bonding the friction material to the disk? If not, then if one rivet shears it might lead to the spectactular failure we see here.

LOL.... first weak link found. next weak link tires/traction then diff/ring and pinion
Good to see you back in one piece even if the shop is dark good thing you put it on the rack before you left.

Not bad for a FB its gonna be like driving on ice when its done at high boost

twin plate is the only way to go unless your a pussy......

twin plate would be nice but too much money for me on a clutch. running a act in the fd for 8 or 9 years now almost 400 at the wheels with no slipping.

It might be good for other cars, but over the years I've found the Centerforce clutches to be primarily a marketing gimmick. They don't hold much power and aren't that well built, yet they're pricey. No thanks.

At least my old clutch had a spectacular ending. I'll admit that I'm actually the one who purchased that Centerforce about 6 years ago for my FC project... I ran it on the FC for about 200 miles before pulling the engine and then selling it another friend who never used it and eventually sold it to 2gslse.

The justification I had at that time was because a friend of mine was using one on his cobra 5.0 with no issues, so my logic was that if it could handle the 400ftlbs he was making of torque, my little 10psi 13BT engine would have no problem with it. I actually learned after installing it that a lot of rotary guys were having trouble with centerforce. Life lesson.. if nobody bought one and blew it up then we'd never know :)


Glad to hear the new ACT is in place. Hopefully you'll have it back before you'e literally driving on ice!

This may be true, Ive bought two of them. The first one I had on my daily for many many years and the second clutch was for my 2nd gen. I've never had any issue with either of mine. I've inspected the clutch on the Mazda after being installed for well over 5 years sometime last year and saw no visual defects. I absolutely love the pedal feel of the Centerforce DF clutch!

Now, with that being said. . I wouldn't buy another. Even though I may not have experienced any problems, that doesn't mean this couldn't happen to me either and those pictures are enough reason to deter me from ever wanting another (I was always skeptical about the Kevlar patches and how they were mounted). I would've guessed that those would have released before the carbon side let go.

Thanks for sharing the pics, I'll be in the market for an Exedy clutch next and at the moment I'm reminded that I should invest in a good quality shield like the unit Goopy produces http://www.rotarycarclub.com/rotary_...ad.php?t=14846

I had a Dual Friction & it was pure garbage. Damn thing came apart on me, but I should have known after the same thing happened to two of my friends before hand. Mine looked like the one above, except one of the springs popped out the hub as well. Then I went with an Exedy set up after the Centerforce shit out.

I never heard anything bad about the centerforce before I bought my first one for a GSLSE so when this one popped up (may as well been free) with no miles on it to speak of I put it in my turbo FB it was always a question of what would be the first failure but I figured it would have lasted a little while before slipping and acting as a fuse to protect the axles. never thought it would explode on the dyno making a pull.

Makes me feel better I never used that clutch, sorry MC
