    650sx impeller upgrade?

    Hi All,

    So i have an 89 650sx. 91+ intake with the 38mm CDK2, Mariner head @175-180psi in each hole, a stock pipe that has been lengthened 4in in the middle for a bigger expansion chamber, stock cooling line routing. Thing runs good, but i feel as though an impeller upgrade over the stock one could be useful. What do you all think? And which one to go with if you think its worthwhile. Not looking for top speed, looking for more out of the hole n punch to mess around easier.

    I have two large hub Skat Trak impellers in 15.5 and 16 pitches. One is brand new the other is out of my personal ski bet you can’t tell which one is “used”.

    Compared to a "skat-trak 8/16 standard" sounds like you have straight pitch impellers. Like stated im looking for more out of the hole, I see a lot of info on a "standard hub" 15.5 being a pretty good option as an impeller upgrade for the 650 but not much about "large hub". I feel as though the current stock impeller doesnt let the ski rev as much as it should, when the pump gets out of water theres lots of rpm left before rev limiter.

    Whats the stock impeller pitch?

    Stock impeller pitch doesnt matter since it is vastly a different design to anything else, no comparisons can be made. Get the 8/16, its the best option for a stock to mild 650.
