    Difference between 14/19 and 14/19r?

    Hello,

    I need to replace my stock impeller for my 04rxp. What is the difference between the 14/19 and the 14/19r? Is the r used for modified engines? My engine is stock and will stay that way.

    Thanks,

    Lou

    According to RIVA's Catalog:
    "R-Series: R-series impellers are precision tuned to our recommended pitch specifications using a fixture called a pitch-block. This delivers a higher level of consistency and performance when matched with Riva Performance Kits."

    Not sure that really answers 100% of your question - but its all I could really find.

    +1, that's all it means and that really doesn't mean chit.. I've never had a prop measure what it's suppost to.. So to answer your question either will do just fine.
