    951 in a 96 xp?

    Well guys, I'm going to get her done over the winter. Any numbers on a stock
    951 going into the x4 hull and what would happen from there when modded?

    Properly setup 951's in the X4 hull wil flirt with 70 on a mild setup (head, f/a's)...

    that's a miller head....

    with a coffman and big bore setup....

    the ideal setup is a stock pipe run 70+ on 93 octane.....

    that's a stock pipe xpl workin a 951 coffman x4 in the video below

    I was running about 67 last year with a Deans 1050 and stock pipe. Motor was setup with a very generous squish. I ran 93 octane gas.

    This year I tightened the squish and added the coffman and some reeds and intake. Still used stock carbs and injection. I ran some premix with the injection on the first tank. I went to the TX roundup in early May. The rear oil injection line broke and damaged the cylinder. I rebuilt with a Miller Ph 3 wide valve 1050 and 48 novis. I have literally been to the lake 3 times this year and have yet to tune her in to where I'm happy. I went to the new style Miller domes that use a head gasket so I have a very large squish. ( 90 thou). So this winter the squish goes down quite a bit.


    IMO... I can't see a stock piped 951 x4 going 70.

    Remember when the 96XP and the 96GSX came out? Both were about 57 to 58 MPH. So wouldn't you think the same mods to both would yield about the same results to each?

    Seadoo then put the 951 in the GSX hull and got around 61 MPH for about a 4 MPH increase over the 785. Do a level 1 mod on the 951 and maybe hit 65 properly tuned.

    Put that same 951 with the same mods in a x4 should yeild similiar results.


    The one probably biggest factor is the engine builder/tuner. I will admit that my tuning ability is lacking compared to many.....at least 2 in this thread.

    it's not all tuning....


    there is some hull set up etc....

    with a stock 951 in my first one...65mph was about all u'd see

    with a white pipe, the right head, reeds and right pump prop combo.....along with some hull changes 70mph is no problem....


    its all in the setup...not necessarily the tuning
