  • Gpr SHO...how fast will it go with stock SHO engine???

    This 2000 GPR went mid 80's with a Lowell 1390 triple pipe with fastest being 86.6.
    What can I expect from a stock SHO with only an air cleaner and ribbon delete?

    At least the same with less maintenance and less noise and smoother power band.
    UNISHIPPERS is the source to ship motors, skis, etc. Call I can probably set you in the right direction.

        I rode a CC setup gprsho at 5000 ft and it was doing 80 or so and it is set up for handling not for speed. I would bet if you loosen it up you are there.

          I wouldn't expect a stock SHO motor will get you those speeds. I ran mid 80's with an ET low boost wheel but was spinning 8500+ rpms. Currently 90+ with an ET high boost wheel.

              Joe's is also not a stock motor set up.

                  if you use a stock motor and ecu be happy with 80 any more the better ! JMO if your hull setup is good even better !

                      I'm gonna set my goal at 78 with the stock wheel and ecu. Over the winter it will receive a boost increase, type 14 intercooler, and reflash. Looking for 90 then!

                        The boat went 75.3 with some bugs to work out. This was on a trashed stock prop.

                              The first day I was hitting the rev limiter at half throttle. I rebent the prop and went too far. I lost rpms, gained speed but lost a little boost. With a stock prop in good condition 78-80 is possible.
