centerforce clutch

So what is the deal with the centerforce clutches needing 500 miles of break in before applying full power???? Does anyone know the real reason they tell you this in the directions????Is there a short cut around it????

I wonder what the guy that has a race only car do????

I wonder the same thing, I ran a CF in a 500 hp '65 gto a couple of years ago. I put it in and never gave it any slack from the get-go. Never had any problems with it.

I think the guys with the race only cars rev it to 5000, drop the clutch, and don't think twice about it.

Break it in first!

The reason for the 500 mile break in is because centerforce clutches have differant kinds of materials in the plate and disc. The time is needed so the plate and disc fully seat themselves. Especially the ones with dual friction discs.

Sooooo, if I drop in gear from 5000 and don't stop for 500 miles it's broken in???

Or do I need a few start's from full stops?

yea i guess thats my point also... I can drive 500 miles and use the clutch maybe 10 times, or i can go 50 miles and use it 1000 times??????

There is on way on god's green earth i am going to have enough self control to drive this car 500 miles and not spank it,,,,And it's not even my car!!!!!

Treat it like a lady!

Don't! Be gentle with it! Here, try using highway miles to break it in. Take a road trip that is 250 miles there and back. Then spank it as much as you want!

I did the 500mile break-in on my Dual fric, and she only lasted a year and a half anyway.

Wrong car?

Did you use the dual plate clutch on a street car? The dual plate clutches were intended for off road trucks only.

It was a single plate dual friction surface clutch made for hipo street machines. I realized after I pulled the burnt clutch plate out, the inherent design problem. The flywheel side has the triangular shaped friction pads spaced aprox. 3/4" apart, while the p/p side has the usual fully covered street fric. material with 1/16th" slots in it. The plate that is sandwhiched between these surfaces isn't strong enough to support the gap in between the fric pads on the flyw. side, so the p/p side is only gripping on the material that is adjacent to the triangular fric. pads on the fly. side. While the rest of the p/p side fully covered fric. material is being pushed into the gaps between the triangles, and thus not gripping, and burning a wave into the weaker p/p side material. I noticed this because the back side of the clutch was worn wavy.

At least this is the theory I've conjoured up to try to explain why I burnt up a 450$ clutch that can allegedly put 800bigblock ponies to the ground, in a year and a half.
I ran a Stage 2 Centerforce clutch that I got used from a buddy who blew his 4spd-went auto, After a year, I tore up the flywheel teeth, and bought a D/F Centerforce 'cause hell, I had her apart anyway. Burnt the D/F, Threw the old stage 2 back in, Just went after another year, used. Best case'o'beer I everspent.
I have a 3150lb. truck. with 3.42's and no traction.
Maybe I can't drive a stick eh!

How fast are you letting off the clutch? If you let it off too slow, then it will wear faster. If you let it off too fast it will probably bend the disc. Do you drive with your foot barely resting on the pedal? If so, then you are "riding" the clutch. If you powershift a lot, well all of these can cause your problem. Or perhaps you got the wrong one?
