    Superjet impeller question

    I have a 93 superjet with HC head running 150psi factory b pipe.

    Iím at 4000 ft elevation and the stock impeller isnít much fun. I rode my buddies SJ with a more torque impeller and it was way more fun, but his came with the ski and he doesnít know whatís in it, I was wondering what you guys recommend for an impeller for more low end torque, but not over the top rip your arms off.

    Thanks!

    9/15 hooker would be a good choice, or Solas Concord.

    I have both available new here;

    Don't let the Concord application year (08-later) scare you. We use this in ALL SJ's and with our blue print service really works very well.

    Either the hooker or try and find a 2008+ oem superjet impeller.

    8/14 hooker and a head with 34cc domes! Also advance your timing at the stator 3 degrees or get a zeeltronics.

    '96 GTX-1mm overbore,F/a's,intake grate,port timed for mid and top end
    '95 FX 1- usually take this motor to 753cc with exhaust porting and reeds
