    RXP-X Stuffing signs ?

    Hello all , I spent the day putting a Riva full stage 1 plus Riva pro block offs on a new 0 hour ski. Also drill 3/8 holes in the shoe and filled ride plate holes. Ran the 82 ring on reduction nozzle.

    After a 15 min. break in I made a few 10 sec. WOT runs.
    No GPS , but RPM's got up to 8,000-8,020 which I think would have been another 20-40 or so had I streched it out a few more sec.

    Question , those that have over stuffing issues , have any of you seen a drop in RPM's just before the stuffing ?
    I ask because a few times I saw RPM's drop about 40 or so on a few runs once I hit peak RPM. Wondered if maybe as the pump builds up pressure it would put a slight strain on the engine? I know is very slight but couldnt help but to wonder.


    By the way the X with stage 1 felt the same " slight more mid range maybe? " as my 06 stage 1 plus RR SC wheel. I ran a stock X with my 06 before and were dead even untill topped out which I would then pull the X by a few.

    "By the way the X with stage 1 felt the same" This is because the 82 mm ring it's causing you a loss in acceleration..

    Anything that disrupts the water in the intake..., Glossy waves make it load and unload quickly... and make it happen quite often and wind driven chop is less likely to cause it, Mostly combined with letting off the throttle.
