    i wouldnt think it would be to hard, ours runs 58 on GPS i would think with an intake and exhaust and maybe a few other tricks it would do it.

    Pump wedge, air intake, aftermarket prop, have the rideplate modded by Jim, then fill the rideplate holes with JB Weld.

    Just a velocity stack and homemade opas block offs on my buddies gf ski "gtx155 "with 3 bars of fuel netted 59.2 mph if we filled the ride plate holes I'm sure we could have got 60
