    3 blade?

    Currently turning a 15/25 Solas through an 83mm to 8720 (limiter 8800) with a quarter throttle left. What 3 blade would get me off the limiter? I saw the 15.5/22.5 skat in the store, but don't know if that's too much/little as I don't have experience with 3 blade impellers.
    I appreciate any help!

    Can't answer your question about the 3 blade but why not try a lucky 13 pump cone ? That will drop rpm and improve hole shot

    I have one but haven't played with it much. Was told I'd need to turn more rpm and I don't want to yet. Hoping 3 blade will give more bottom and mid pull and keep top end mid 80's.

    I'd send Jerry a note, he will know...if not he will reach out to Glen at skat trak. I have a 3 blade on my as260 (stock) and my 0-60 went down by a second and no loss in top speed. I will probably move to the 3 blade in my turbo PX...love the acceleration. Lucky cone will help...just be carefull of stuffing if your in the mid 80's already.

    I have two prv's, but lost a little top speed so I blocked them off with plugs until I tickle 90, but I won't be there until I turn over 9k. Blew my water box apart last outing, so I'm down till new one is built. I'll email him and work on it thanks.

    Best advice I can give you is to stick with your 4 blade impeller and install the Lucky 13 done. It will give you more bottom end and midrange pull. You will be impressed!

    When box is complete I'll play with washer combos.
    Comparing identical setups, L13, Venturi, etc, which impeller (3 or 4 blade) will be stronger bottom to mid?
    Which impeller cavitates more/less with identical setups?
    Thanks for any help!
