What the most power an oem W-58 clutch should hold, with out dumping it a whole lot? Is there a better pp that will go well with the oem disc.

drjonez is right if you are thinking of running more than an exhaust and intake on an NA engine while beating it up youll be sorry. If you want to push power through an NA drive train upgrade the clutch or go with an R154 setup

Im running 12psi and I blew another clutch, I was thinking will the oem clutch disc hold over 300hp with a better pp?

not going to happen. you'll need some whacked out PP to hold that on a full face organic disc....

So could I get a better clutch disc and oem pp or am I looking at another chunk a money for a nice clutch kit. The reason I would like to stay with oem is I have lifetime warrenty on it but it just does not look like its going to happen.

sure, you can stay OEM....and keep replacing it every other week. for serious power, you'll need a serious clutch....or swap over to the R154....

Do you have any suggestions for a w-58 clutch for around the 300 crank hp range?

the only clutch i found to hold my 310 rwhp was the CM stage 4....and it even held 460 rwhp. too bad it sucked to drive....you might want to call up HPF and talk to jeff re: feramic disc + ACT PP....that SHOULD hold....

I don't see any feramic listings for the W58, but I'll check into it tomorrow...

The Spec stage 3 is rated to hold 359 ft-lbs. I'd normally recomend having more of a margin as you may be close to that torque level, but its the highest torque rating for a sprung hub I'm aware of for the W58


Edit: The SM stage 4 appears to be sprung. Guess my recomendation will change ;)

twigger why dont you just get in touch with the guys are RAM clutches they sold me my clutch and Its for aW58 tranny. Its a 6 puck unsprung clutch ..... no before anyone goes saying how the hell do you drive that let me explain. Its a little chattery off the line but after that if you slip it nicely you can go through the gears without any chatter. If driven aggresively its grabs you like crazy you will feel your teeth fall out if your racing and shifting hard but it will never slip. I have pushed it up over 20psi on the stock turbo (this was an accident) and there was no problem.

DO NOT use an unsprung clutch disc. the last thing you want to do is give your trans another reason to blow up....the springs absorb shock to the drivetrain @ all times, not just @ take off.
