    Here is a prop spec chart, that Jerry had provided a while back -

    Seems as though the 2012 FZR impeller is the 6S5-04, at a 13.4/19.7 pitch. Just try & get the OEM prop pitched down to suit the app, or IMO you can't go wrong by running a 155 Skat.

    Based on my experience you might be pretty close with the stock prop. What RPM is he running now at WOT?

    My OE prop (2010) measured 19* on two blades and almost 19.5* on one blade. The leading edge was 11* for the first inch and then 13* for the next inch. I would check it or have it checked first and see what it is before you change anything.

    He might want to raise his target RPM to 8500 and get a little more boost and top speed.

    Add an intercooler
    I got to 8,500 with stock prop and stock boost
    Only difference to your mates setup was intercooler
    And I was using a Motec
    So tune may have been a little different
