    Scooby the Vortec SC impeller won't make a lot of differance on the top end but the acceleration will be much better and you will hit that top speed a hell of a lot quicker.

    hm... my numbers are out of the ordinary given what u guys posted.. but i guess that's also because i'm riding in some cool cool weather right now and much further north than you guys..

    with my own homemade 4" air intake, thru-hull exhaust, NOPAS, pump wedge, Solas prop i'm doing 71 mph

    i gained 4-5 mph over what the machine was doing one stock (about 66.5)

    still have quite a few more things to installed and hopefully break 75 mph on the RXT in the next week

    this is true!!! i forgot to mention that in all my speed posts, bc i'm sure it's very important. some of you guys probably got an extra 100 pounds on board versus me weighing in at 130lb even last time i checked
