    Vtech stage 1 with 8350 RPM limiter on stock prop will get you around 72mph bouncing the rev limiter.

    add 4" air and a 15/20srz prop pitched right and you should see 75.xmph

    With the 15/20, you should be right in the ball park for the correct RPM's depending on the weather. 95 degrees, 80 degree water temp and I was just getting up to it. However, beginning of this year, 55 degrees, 45 degree water temp, I was all over the limiter.

    hello, i think to instal the vtech 8350 ,RIVA or R&D filter,and manifold upgrad, my question are:

    -IS it better to instal a RRFPR with theses mods?
    -Who can repitch correctly a brand new 15/20srz for me?
    -are these mods better with a free flow thru hull ? OR its not necessary?
