Clutches are rated for torque capacity, not horsepower. Torque of a supercharged f2x is very different from a turbo.

ACT/OEM Combo is good for a little over 300ft/lb for most people. Some people have luck with a bit more.

A 13+ lb flywheel is helpful in preventing clutch buzz as it helps to damp the power pulses or torque spikes that happen from combustion.

I make fully caged Clutchmasters discs so that the springs won't pop out like they often do on other aftermarket clutches.

If you street drive a lot and don't want harsh engagement, I'd recommend something like the FX300 segmented disc with the fiber tuff organic material.

Clutchmaster and ACT pressure plate have very very similar clamp force. ACT seems to have a bit of variance from unit to unit, but is typically around 2600lb vs the 2400lb of the CM pressure plate.

Yes, swapping the disc to a segmented or pucked disc will increase the torque capacity.

I’m using act/oem combo and making 540/400 and don’t have slipping and it’s very daily friendly.

 

Thats so awesome. I wish this was out when i pieced together my oem/act setup. That throwout bearing is the good one too, with the orange bearing.
