930 clutch release fork?

i need some sage advice as to the throw bearing actuator arm on an early 930 transaxle. i know some of you guys must run some rather extreme clutch and pressure plate combinations. is the stock actuator arm capable of pressure plate spring pressure say...of 600 horsepower...600 ft/lbs of torque? i have broken a couple of 915 arms using stock clutch components. thanks

I think the stock fork is pretty stout. If you sticking with a cable to operate it, you may need to adjust it or be ready to replace it as there is more strain on it. I just installed a KEP stage 2 clutch in my car with 400 rwhp and so far so good. I did buy the cable as a spare in case I have a problem down the road. The other choice is to with a hydraulic set up like Brian Smith.
