    Question Question about impellers.

    Hi all,
    I read the sticky, but im still unsure what impeller to use? Currently the ski has a 14/20. However after riding it, it seems that it lags alot of low/midrange pick up. With GPS I was able to make 67mph, so I was happy with the top speed. So, just wondering what size impeller will increase acceleration without sacrificing to much top speed (hopefully not sacrifice any!). Im looking at eventually installing a 3 Degree key (as per my other post) but was going to explore the cheaper option first...
    Mods on ski are below;

    New Sponsons
    D-Plate

    Forged Pistons

    Thanks!

    have the leading edge depitched down to a 13 and it will have a better hole shot. A key way will help a lot with hole shot.

    Will that affect top end speed much?
