    More P-X stage 1 numbers

    I recorded these a few weeks ago, but never got around to posting.
    With a stage one and ride plate holes filled, minus the prop and reduction nozzle I recorded the following:

    Upstream
    72.5 mph
    Downstream 74.4

    water temp was mid 70's
    air temp low 80's
    no wind, as it was a very still day
    4 bars of fuel
    Superman position for riding
    Did each direction 3 times and the numbers were consistent. Just goes to show you how different your numbers can be depending on if you are going against or with the current.
    Just received the 15/22r from Jerry (thank) so will install and redo. I never plan to get the reduction nozzle so it will be interesting to see what just the prop adds.

    Just thought I'd share my findings...cheers

    Sorry forgot to include that
    rpm's are 8160 on average (+/-20)

    One other thing is I am pretty sure I will get more with a prop...I am at those speeds with the throttle about 85% engaged. Meaning I still have more to fully squeeze the throttle but I reach max speed first. Hope that makes sense.
