ceramic and feramic clutches

[DRiddel]

Whats the difference in ceramic and feramic clutches? Good and Bad for both on high hp motors. And which one you would pick. Thanks

"Ceramic" usually refers to a brass/carbon sintered material. Feramic is iron, usually a plate that is either puck size or covers the entire surface. Both work; feramic takes about 2500 deg. F while brass takes only 1500 deg. in case you like to roast it sled pulling. Other features of the clutch can also be very important to grabbiness, holding power, etc. Peter Pyfer at South Bend Clutch seems to like the feramic lining he uses on his con-fe clutch His product has high holding power, high restistance to heat, lasts well and has smooth engagement. I have used the Miba brand ceramic pucks on a reworked Sachs clutch for excellent holding power in the 5 speed trucks, but it is grabby bacause it doesn't have the "wave plates" or marcle behind the facings.

Joe, when are we gonna see yer "real-life" test results on the LUK cerametallic?



Mine's been doing great so far...

 

[Joseph Donnelly]

The testing has been slowed by my knee surgery. The Luk works fine, but I can't say whether it will wear the flywheel surface faster. Peter (South Bend) thinks it may. I ran his Con-Fe for 10,000 miles and reluctantly changed it to the LuK because I felt I needed to see how the Luk would do.

I don't much doubt the Cerametallic will wear the flywheel/PP somewhat faster than a stocker in relatively heavy use - competition or consistent use in heavy towing - but not sure what the wear difference would be between the South Bend Conofe and Cerametallic in identical heavy-duty use...

So far it holds to 520hp and 1245trq on Stomps first gen.

Yeah it seems to be holding just fine. Over the next couple of months we will see how much abuse it can handle. Were uping the power. Oo. Oo.
