    That depends on many things: intake (4in?), injectors, intercooler (stock?), water box (baffle?), intake grate, wedge?, nozzle diameter, altitude and temp...
    Try stock. If it turns to red line, 8650, pull it and switch to a 14/19 or 15/20. Good luck!

    15/20R fine tuned to your setup. I can help you with the pitch work if needed

    I'm going to be adding a 15/22R to my PX, can you pitch it for the correct RPMs before shipping if purchased from the greenhulk store or are these drop shipped from the manufacturer?

    I can't pitch any prop until you run it first and see where your RPM's are. Then I can accurately pitch it for you.

    I don't want to hijack this thread but i was wondering which impeller to use. I need a new wear ring and impeller now but I'm going to install a RIVA/ATHENA Pro-Series iControl ECU when they are released next year and this is the only mods on my 2009 RXTis 255 ski. So my question is what impeller would be needed with this set up?
