    A general guide is 1 in/lbs per psi of boost, but normally i think people run just over that as after the s/c has been broken in the slip will reduce..

    Send it to Jerry if you have any doubts, its better to be safe than sorry.

    if you rebuild your SC, you can not set the slipmoment, you just use new parts and you close the last nut with 20 lb ( 30M) thats it , your slipmoment should be over 7-8 lb or a stock X-SC.

    I'd like to piggy-back on this with an expanded question. I'm nearing the 100 hour mark and want no down time during the season so I'm considering sending mine to Jerry for the rebuild (I have a P-X).

    Is it fairly fool-proof to remove and install the SC to send to Jerry or could I damage something (considering the worst case scenario - knowing my luck)?

    Too, I love the acceleration and would consider the Riva X-Charger Pro-Series Impeller & Housing. It says the 50lb injectors are required as is the reduction nozzle. Has anyone done just this mod? I like how it won't need the ECU upgrade or the fuel pressure upgrade, but that's an additional $1200+ and if I'm going to lose acceleration with the reduction nozzle then I might decline.

    Any input is appreciated.

    RX, here is a bit of advice since I am fairly new to modding myself.

    Start out doing the smaller things before you are off to tackle injectors and af readings/balance etc.

    Send the SC to Jerry for a rebuild for sure. I just got mine back from him. Mine only has 37 hours so I just had him install the riva clutch washers and mcmaster spring washers. Yes the sc is fairly easy to pull. There are instructions in the how to area. Go ahead and get the riva washers and mcmasters as well.

    Do all of the others mods to get good and familiar first. I figure next year I may upgrade the SC.

    I have my ski all apart currently since Im redoing my IC and going thru hull exhaust and blockoffs. I did the FA mod earlier in the year and Im just now starting to feel comfortable inside the engine bay.

    The mini rude is probably a better choice by the way. You do not have to purchase the reduction nozzle to run these.
