    it really depends on RPMs. you have two props there, try each one and see which one will get you the best speed and best rpm range and best acceleration. try to get your RPMS as close to 8100 as possible

    once you test the props and know the results, you can repitch one of them accordingly.

    Pitch is the theoretical travel of a prop through a mass per revolution. An impeller has a progressive variable pitch,which means the pitch increases from front to back and from the hub outward.Therefore the 14/19 prop progresses from a 14 degree front leading edge to a 19 degree to the trailing edge.

    u'd have to direct that question to Green Hulk, or a preofessional impeller shop like Impros, Island Racing, i think Race Tech repitches?

    You can repitch it to a 14/19, BUT the root of the blade where it meets the hub will still be 14/17 or 13/19

    I run the 13/19R repitched to 13/181/2. My RPM's were to low,about 7900 with the 13/19 and I was bumping the limiter with it repitched to 13/18 so the eighteen and a half was just about right,I run 8100 to 8150 my best GPS speed was 70.4. Run high 69s and low 70s consistantly.I have the Riva stage two with the R&R intercooler instead of Riva's. I will be putting the R&R ecu on it then the 13/18 may be right for it with the increase in RPM's I will be running.
    Shibby is right,try both props and see which one is closest to the RPM's and speed you are looking for then you have a good baseline to start with and then repitch accordingly.
