I'm putting in my centerforce dual friction tonight at my work. once its running, whats the break in process? how many miles and what rpms and stuff.

Also should i have my flywheel resurfaced or should it be fine?

fly wheel at least should be resurfaced if not replaced. break in is generally 500 miles and dont go above like 3k rpms and stuff. personally i think break in times are dumb. my clutch went in and got on it like normal with no break in time. Clutch still grabs hard with no problems and had it for over a year now.

Definitly resurface the flywheel if it's not brand new. For the clutch, just normal intown (stop and go) driving for 500 miles. That means no flooring it.

drive it easy and drive it hard in stop and go. You ideally wanna vary the rpm's and such. Don't just go on the highway. My clutch had 1 mile on it before it saw 5k rpm. You do NOT need to wait "500+ miles" to "break in" a clutch. Not that I know anything, i've only done it a few times

Replacing your flywheel is prefered, but resurfacing will do.

The break in will also depend upon the composition of the disk used.

Flywheel bed-in and clutch disk break-in have different needs, but following a trend of varying speeds and nothing excessive (unless you are Mike ) is generally a decent way to go.

Good luck.

Even if I wanted to do the easy 500 miles thing I couldn't. As you know, my motor is brand new. I wanted to break it in correctly which is giving it 1/2-3/4 throttle bursts and letting it decel in gear. Obviously I waited til it warmed up. What that does is put some cylinder pressure into the cyl to get the rings to seat. So there ya go

DO YOURSELF A FAVOR AND BREAK IN THE CLUTCH 500 MILES, MOSTLY STOP AND GO TRAFFIC! (around town and no highway). Unlike other clutches (king cobra, McLeod..), the Centerforce Dual Friction Clutch NEEDS to be broken in for 500 MILES or else it will prematurely wear out on you. I'm currently using this clutch and noticed that with the slight chatter and engaging when new, it defiantly needed to be broken in for the mandatory 500 miles around town.

Larocca's Performance recommended this clutch to me but told me at least 100 times that it MUST be broken in for 500 miles driving EASY and around town! He said he usually doesn't recommend it to his customers because they come back complaining it slips when they go to the track the day after it's installed.

PS- Sorry for the caps and repeating. Just don't want to see him lose a great clutch because it wasen't broken in correctly. Properly breaking in a Centerforce Dual Friction clutch is a must.

Mike, point taken. But I don't think Nightrider is not breaking-in a motor at the same time, so he can break the clutch in properly. Were I in your shoes (Mike), obviously you follow the break-in procedure for the most expensive component, which is the nice new motor. And you are likely not doing anything to slip the clutch much (which was the connotation I got when you mentioned 5K RPM earlier. I did not know this was while breaking -in the new mill).
I never understood why people dont break the clutch in properly. It costs nothing but some time, and the possible loss of a nice clutch is the cost for impatience.
To each his or her own.

Just got home from the shop. my flywheel has cracks all over it and looks like shat. so it is going to get resurfaced tomorrow morning.

I was planning on going to the track on wednesday night but i guess i should wait an extra week and put on 500 miles.

thanks for the help guys.

If the flywheel is cracked, I would replace it. Should be ~100 bucks for a new one.
Just me.
Good luck.

How much power should a engine be making before you stick on a dual friction clutch? Im looking at this clutch but will be ~300hp ..

I dont think you have to have a certain amount of power to have a dual friction.

The flywheel it is just those little heat cracks like on brake rotors. and there is still lots of surface left so it should work out fine. plus my boss's brother owns a machine shop so it will be free. woohoo

A dual friction can handle probably 450hp without wanting to slip.

Absolutely (as stated by most) break-in a clutch...I have did many break-in/swaps. It is one less variable to weedout if you break it in properly and something goes wrong. Proper seating is a must especially if you have a clutch that is on the borderline of holding the power you have...
