    X-Charger Fuel Requirements...???

    My buddy, I don't think he has registered here...YET...but he has just bought an X-Charger and X/S intercooler for his stock 06 RXP...

    We are doing 4" Riva Rear Air, 15/20 prop, Intake Grate, and Pump Wedge...and MAYBE an exhaust upgrade

    As for fuel delivery on the stock ECU we plan to use a RRFPR...what should our INITIAL base pressure be set at...?

    I think I know the answer to this already...but we cannot use 42s right, too lean on top?

    What about OEM 'X' injectors...could they be used?

    Can you run the XS with stock exhaust?

    Good question! 42's and what setting on the RRFPR? suckmywake has this set-up! Snowman might have this answer!

    RRFPR and stock 38's will work fine with the external IC and X. Set it at 60psi ENGINE OFF and roll.

    I would go with the RRFPR and keep your stock injectors.Set your regulator to 60 and you should be ok..My sugestion would be to get an A/F guage that way you know exactly what you have for rich/lean conditions..
