    On the fence with Prop

    Just finished a few updates (intercooler reloc, wedge, riva BO pro series, riva waterbox) been out twice since I finished. Still running a stock prop. Both times out I had a top speed of 74.9. One day i was at 8140 rpm's and the other I was at 8080. Both days exhaust temp was around 68 but the air temp was warmer on the lower rpm day. My question is should I purchase a new prop, I have to assume the waremer the weather gets the more rpms i will loose? If so which one? I am under the assumption if I get a 15/22 it's going to lower my rpm's more and will have to be re-pitched, just curious and confused where would be a good starting point.

    Sounds to me like you don't need a new one. I see you have nozzles switch them up for more rpm.
