    RPM and Heat Soak Question

    I am currently hitting 8500 rpms in the Texas Heat at 98 degrees F*
    When the weather gets cooler how much will my RPM's come up?
    I am running the Rotax racing ecu

    Should I re-pitch the impeller to bring my RPMS up closer to the limiter 8650?
    but come winter time, I would hit the limiter and have to de-pitch?

    Going on my third editing.......

    Have a summer impeller and a winter impeller.

    If you're using a Riva ecu your rpms are just about right at 8500. With cooler air/water expect to be over 8500 by as much as 100-200 rpm.
