    Fx sho problem

    My ski seems to only be going around 50mph its 2008 fx sho with 70 hours on it . I took pipe off the supercharger and it only spins one way . The pipe that it connected to the bov has pressure in it when I rev the engine . The ski revs to 7k my be just over that . But ski still only does around 50mph . I'm going to try spark plugs Just waiting for them to come . What else could by my problem ?? Could the plugs sort my problem

    How old is the fuel?
    I would add some fuel injector cleaner to the gas. With only 70 hrs on a 08 thats like 12 hrs a year and its had to have had old fuel in it at 1 time.

    Check yout compression #s. Not saying thats your issue but its always good to know...

    How's the pump? Like the impeller and wear ring. Any dings or excess gap?

    Check all your hose clamps, then check them again. I'd be willing to bet one jr bacon cheeseburger that your SC clutch has gone bad tho.

    Edit: do they have Wendys in the UK?

    It's over 7k revs in water . The clutch only spins one way also the pipe with the blow off valve expands when revved

    There is no need for a bov on a stock sho.

    Bov are known to crap out and release valuable boost...
