    08 Rxp 255 build thread

    This thread will be updated as more is done with the ski

    I acquired this ski in March of this year with 30 hours on it, previous owner had the charger washers changed, new prop (unknown size, said they had it 田ustom pitched), and stainless steele wear ring, ski was in mint condition

    So far I have done the following mods:

    - free flow exhaust
    - r&d Intake grate
    - opas blockoffs

    I have the 4 kanaflex intake kit in my shop ready to be put on

    Top speed at this point is 74mph gps at 7800 rpms

    shooting for 80mph, I知 still new to this so any advice would be much appreciated, stay tuned there痴 a lot more to come, I値l add pics below

    74 at 7800 with a prop and intake grate/Exhaust? Wow.

    I have the same ski with prop/4" intake/Riva IC/Free Flow exhaust/Intake Grate and i'm lucky to see 72 at 8120.

    I don't know how you are getting that with those mods....maybe with the 4 inch on......With those RPMs you must have a tall prop....

    Assuming that speed is coming from the dash not a GPS? To get 80mph out of a 255 at minimum injectors, wheel, and supporting mods.

    I was surprised to see the speed as well, stock I saw 68-69mph, with the free flow and blockoffs I saw 71, and when I added the r&d I see 73 consistently and got 74 on glass water at sunset. The prop was on the ski when I got it, maybe my gps is screwed up who knows
