Anyone running CFDF Pressure Plate with non-CFDF clutch disk?

[bvass]

My Center Force Dual Friction clutch has been great for a couple of years but now that i moved to a bigger turbo and started making more power it started to slip after a couple of hard launches (1 hour cool down time between launches). I am thinking of resurfacing the pressure plate and flywheel and going with a different clutch disk. Has anyone tried that before? Can you please specify witch disk you used and how much torque you were making?

I am hoping to put together a combo that can hold 450 ft/lbs of torque and take more hard launches at the track.

I know it has been done before, recall a guy on DSMTalk with the CF DFX PP which as far as I know is basically the same as the DF & I believe he used it with an ACT sprung 6 puck. Last I heard, he was happy with the setup.

You use to be able to run the CFDF pp with the ACT discs, but last I heard the new design of the ACT discs dont fit with the CF pressure plate.

But for confirmation, I ran a CFDF pp with an old ACT street disc.

I ran a CFDF PP with a South Bend kevlar disc. Great street clutch.

This is the exact clutch disc I am considering. Am I correct to assume it holds the 520ft/lbs of torque in your profile without problems?

Also do you remember the part number of the clutch disc? Was it 735 TZ?

It did not hold it for long, after 5k miles and about 3 lauches it gave up. It still held the roll ons but as soon as I put some heat in it she started slipping. I went to the twin disc after that.

This is what happening to my clutch right now. I would guesstimate that I am putting out around 400-450 ft/lbs of torque and after my third launch the clutch started to slip. I waited an hour between launches to give it time to cool off. Did you see any improvement after going to the Kevlar disc over the CF clutch disc?

I never ran this motor with a CFDF clutch. Just the CF pressure plate I had laying around. It was just a band aid until I got the twin disc. The Kevlar is good until it heats up then it needs to cool down to work again. But unlike a standard fiber clutch it is still good to go after that. If you burn up a standard fiber clutch it is pretty much shot after that, it won't quite have the tq holding ability like it used to. The setup was just a little too soft for my power & torque. A better pp would have been something 2600 lbs and up. I forget what the CFDF plate is rated at but I think it is near the 2300lb mark.

As far as I know RRE tested the CFDF PP to 2500 lbs which puts it very close to the ACT2600. The reason I want to go with CF PP is that it has a very soft pedal feel and it does not put as much load on the crank as the 2600.
