    You won't go any faster until you replace that old worn out wear ring (remember our emails?)

    and you are leaving out pertinent info... How many rpm are you turning now?
    you do understand that going with a higher pitch impeller will give you even lower rpm?

    Slower than it is now! Depending on the desired rpm you want to run, turning a 15/22 takes a lot of power. On a stock charger with a 15/22 pitch prop.... you'll be running slower than stock!

    At wideopen throttle how many rpms are you turning?

    15/22 is a big prop like others have said. The bigger the prop the more power/boost you need to turn the prop.

    On my px I went almost 80 on the stock prop just by bending it to my needs.
    (8900 rpm not stock rev limit)

    You set the prop to get almost max rpms that way the supercharger is making the most boost and you are making as much power as you can.
    But you cant stay on the rev limiter you have to be under the limiter.

    More boost, more rpm's = more speed.

    I am pretty sure I came up with a formula a week or two ago!!

    Couple of questions...

    What ski? (if different from your avatar)
    What current mods?

    A 15/19 prop is a 3-blade, and a 15/22 is a 4-blade...Both props are different animals....

    Look at all my mods in my sig. I went from running a 15/20 on the 8600 limiter to a 15/22 running around 8300 rpms. I lost about 3 mph because I dropped my revs too much. I plan on running a higher tune and adding just a little to my 15/20 to get me where on want to be next season.
