    Fuel Requirements for X-Charger

    Want to transplant some X parts into my 07 RXT.

    Can a stock 07 RXT ECU work with the X-Charger + stock RXT I/C with 42 injectors?

    Do you think the stock X prop would work with this combo? I was thinking of using the X Nozzle for the hole-shot.

    don't see why the 42's wouldn't work with just an x-charger. Should be able to run an xs ic. Basically an x set up less mid pipe and water box. Anyone else have any opions or know for sure?

    :edit:

    I think the 42's will be ok as long as the stock IC is in place. The stock X prop will be very close for you.

    I am running an X charger with an x prop and rear air with 42's. Awesome
    setup in my Rxp.

    Once you put in an aftermarket intercooler you need rrfpr. Speed skip
    tested without and it was lean at wide open throttle.

    He can give you the numbers with and without pressure regulator.

    jpe had the same experience. He ran the RRFPR with the stock injectors and melted the exhaust manifold nipple very quickly.

    doesent the fact that one boat runs 12 and the other 14..volts count..... so making the fuel maps on the relavant ECUs a major factor?.....

    Wow,

    I feel sorry for the guys up north in the cold. Speedskip tested one in 78 degree temps with water temps in the 60's and was lean.

    Everyone said I would be ok with out rrfpr but Speedskip. He was the only one I knew that checked it. With that set up.

    so do you recommend 42's in addition to the rrfpr?

    You will need to set the fuel pressure on the RRFPR down to 53-55 PSI if you are using 42# injectors.
