Does anyone know the holding capacity on one of these, all I can find is 90% Greater Holding Capacity, but what does that really mean? I'm looking for a number horsepower wise.
I like the idea of the light pedal given by the ability of the weights to clamp hard under load.
I just wonder if that clutch disc is really up to hard use.
If it can't handle slicks and glazes up, then maybe the CF pressure plate could be combined with a high quality disc for better results... ???
I know of alot of brand x owners that swear by kevlar discs for hard use.
They can chatter on soft take offs in daily street driving, but are said to be killer stable for hard launch.
So that brings me to wonder if the weighted plate might be the perfect combo with a kevlar disc.
Just a thought.
Once you are in higher RPM range the additional forces that those weights are supposed to create are not really needed to keep the clutch assembly clamped up.
The weight thing is pretty much a marketing gimmick. They are supposed to help the plate clamp up better at higher RPM's.
Have you ever had a clutch that slipped only at higher RPM's?
Bad clutches pretty much slip at takeoff and in the lower engine rpm ranges when lots of torque is needed in order to get the vehicle moving. Once you are in higher RPM range the additional forces that those weights are supposed to create are not really needed to keep the clutch assembly clamped up.
Other companies (such as Spec) offer various clutch disc facings for use with their diaphragm clutches. They have 5 basic options as far as the disk goes. As you get a more aggressive disc material, the chances of chatter increase (as does the removal of the little cushioning springs found on the more street oriented discs.)
There are independent companies that have experience at matching various brands of discs and pressure plates. Most can give pretty good results, at a fair price.
I've had one since the 1st month they were out. After decades of having to choose between a drive-to-work clutch and a Saturday night special clutch I will never run anything other than the Centerforce. And their 'claim-to-fame' is the sintered iron surface next to the flywheel and fiber surface next to the p-p. Ther have been centrifigual assist p-p's for as long as I can remember.I run the Centerforce DF.
Pedal is nice and light.
I don't have a great deal of engine, so I can't comment on that.
I checked your link to the Ram.
That thing is a dual disc unit, not just a dual friction.
I don't see any weights either like the CF.
I think that Ram is a whole different sort of setup.
The CF has weights that spin outward as rpms increase to put more pressure on the disc. That is the CF claim to fame.
Personally I like it.
I have had some really strong clutches before, and pedal pressure can get crazy.
Not so with the CF.
