    Riva stage 1 in an RXP-X

    Riva provided a 15/22R impeller with their stage one kit for my RXP-X. I operate mostly on water in Colorado ranging from 5000 ft to 8000 ft in elevation. Is the provided impeller optimal for my application?

    I get about 7400 rpm on Lake McConaughy, NE and 70 mph (~1000 ft elevation). I get about 6500 rpm and ~65mph at 8000 ft in CO.

    Should I switch to a 14/19R?

    BTW, what do the numbers mean in impeller sizing? Is that 14 mm / 19 mm??

    The only way to truely tell is to install the 15/22 and run it. Make note of air /water temps and RPM's. If it's within tweeking distance(acouple of 100 RPM's either way) pull it back out and tweek but if your way off(500+ rpm's) you'll most likely have to change your impeller.
