    What next ..2007 rxt with X charger 42 lb injectors

    So what next.....The ski is stock other than X charger and injectors , after market impeller(it's almost getting to limiter now )

    What intercooler do people run?
    What what impeller pitch should I run (stock ecu )
    Fuel pressure reg (will stock pump be OK? )

    Intake and exhaust is all stock also,
    just after ideas of what direction to go.
    I would like to keep factory rev limiter.

    wanna do it on the cheap? 14/19 as he said, Rad 4 torque plate and 2* wedge. Get the hull out of the water. That's cheap and will change the machine.

    Fuel pressure reg (will stock pump be OK?)ONLY if you add an external IC and exhaust,Stock fuel pump will be OK BUT it is recommneded to upgrade to a Walbro or Aeromotive seeing how old your ski is..
    Intake and exhaust is all stock also,

    That sould be no problem,just pitch your prop accordingly

    God bless ya for not having any issues....I have seen major AFR swings do to the weather/climate changes here in Chi-town with that setup on the wifes ski.....After seeing that i would never run this setup without a RRFPR and a AFR gauge...
