i just installed my centerforce stage II clutch and wanted to know the best way to break it in. it says to put about 400-500 miles on it before opening it up. But on these high reving engines, what is "too much"? i have put about 120 easy miles on it, and last night i hit 4.5 grand twice... is that too much? Oh, and these miles should be city right? or could i just go ahead and take a little highway trip and get it done with?
I just put sooo much time into doing this clutch, and don't want to have to do it again for a VERY VERY long time.
thanks for the info, jeff

As long as you don't do any crazy shifting at high RPM's for a few hundred miles you should be just fine. Lot's of easy shifting (city) will break-in a clutch ... highway driving won't break-in a clutch at all.

Inittab-
What is that avatar? Is that an old rotary design?Dont mean to hijack this but that is cool

Oh......and highway miles dont break it in cause it has to being slipped, so just cruise around town alot

hmm... well I guess I'm not as patient as you guys..

I put about 150 mixed city/highways miles on the clutch then did 12 runs at the dragstrip. Think that it's broken in now?


Centerforce dual friction...

That's the John Cooley rotary steam engine; American, 1901. Perhaps Felix Wankel may have had a glimpse of this doncha think?

Aww.. inittab, you shouldn't ditch the Red Dwarf... that show is awesome man.. ad the "steam rotor" to your sig, but for heaven's sake, leave Kryten where he should be!

Yeah I know..... it was a hard decision but....well.... it was time for a change and that Cooley engine is pretty damn cool if you ask me.

what actually happens during the break in process of a new clutch? my best guess would be, because the flywheel surface and new clutch disc aren't perfect, to wear the new disc to meet up with the imperfections of the flywheel so a larger area of the disc contacts the flywheel, hence more holding power. did i guess right? i already posted this question in another forum but not to many people visit so i figure i would get more responses here.
