    xp800 upgrade to magnum pump Q

    hi all,
    need info for upgrading my xp800 standard and using magnum pump. which magnum pump to use and what is the best impeller for it.
    my ski is stock, except the airfilter.
    and also what single pipe is best for it? would this 2 combo(pump n pipe) is a good setup for close course? just for fun ski not race.
    also, where to buy the pipe and pump?
    thx for helping,
    dre

    this is a good setup for a rec boat...

    spec 2 pipe
    water injection
    miller head w/ pump gas domes (42cc?)
    re-flash mpem (I would use msd enhancer)
    large hub rfi plastic pump
    16/24 swirl impeller
    r&d 85/88 nozzles
    worx sponsons
    top loader intake grate (umi or r&d)
    complete umi steering


    you can re-jet the stock carbs, but 46mm aftermarket carbs will give you more power & less fuel range. a lot of racers (including me) have had good results with novi carbs.

    expect 62-63mph with the above setup and arm pulling acceleration.

    no need for magnum pump.

    Yep I really liked the RFI pump in my SS HX it makes a big diff in the rough stuff & is realitivly cheap,around $450/500 with a prop.

    I can sell you pump if you want.

    PM if interested.

    thx guys for the info, the large hub rfi pump will fit without any mod? and where can i buy the rfi pump? any part number or which store to buy? thx.
    also, where can i buy the spec 2 pipe? web link please. thx

    i live in indonesia, so it is very hard for me to reflash the mpem.
    but msd enchancer i probably can buy it. i heard some of my friends use it.


    thx much for your info, really appriciate it.

    try seadoo.net for the spec 2 pipe. you can prob find a msd enhancer over there too.
