    Pitch question for turbo ski

    I was wondering if anyone could help me out, I have a 06 RXP that I have turboed and I am running a 3 blade impeller it is pitched at 17/21 right now. Does any one know if this is close to what I should be at? I live in Kansas right now temps are high 90's to low 100's but our humidity is high. My rev limit is set at 9200 RPM'S. Thanks

    @ 9,200 you should try a smaller prop, like a 15/20 or22 solas, or a 15/19 3 blade should let you get the RPM's u need, without going crazy on the boost.

    I have a Borg Warner EFR 6758 I am currently at 17lbs boost would like to be at 20-25lb boost at 9200 rpm. So would everyone agree that a 15/19 3 blade would be the best? Thanks for everyones thoughts.

    With that turbo at that boost level I think a 23 pitch prop would work well and get you in that range. I think the 15/19 might be a little light for your desired boost level. Give Speedfreeks a call he will set you up with a 23 or so pitch prop. Solas 4 blade

    O.k. @ that boost level, closer to a 15/23 to 25 4 blade should be in range

    or a 15/20 3 blade Skat would be close
