    performance question

    lost my old thread... lol

    but turning down the idle out of the water will or will not affect the performance of the ski?

    i guess what i mean is if the idle is turned down to low will the Ski go slower as a result? will the max rpm go down as well?

    im trying to figure out why i have a 10MPH drop in speed since impeller replacement and idle tuning.


    (stock impeller) pro 1200

    as of now its around 5500 tops In water...

    it feels good its picking up ok its just alot slower than before =( i thought if the idle was tuned down then i would not get the pick up and top speed as if it was turned up.

    Idle speed wont have anything to do with top speed/throttle position at WOT. 5500 is low for WOT. That impeller may have dragged it down.

    Your idle speed/rpm at idle will not affect wide open throttle speed or engine rpm at wide open. They are not connected to each other.

    What type is the impellor and the number on it? that will tell us the pitch. some are for low end acceleration , others are for top speed. you cant have both. indy car or drag car, you chose.

    What do you mean stock? From the Polaris spec sheet ? do you know the pitch? 12/17? 15/26? who told you it was stock?
