Thread: MPH estimate question

  1. #1
    jbone
    I've got a 3500lb 21 foot Shockwave jet.
    Currently turning the A impeller 4800 rpm at 58 mph with about 415 hp.
    I'm upgrading to about 540 hp. Any ideas what 540 hp at 5400 rpm should do with an AT "A" impeller??
    Thaks,

    What is the JPC I???
    I do like what it says though. Seems a little unrealistic though. Has the JPC I proven reliable?

    Hmmmm, WISHFUL THINKING... AT LEAST ON MY PART. DON't KNOW FOR SURE YET, MOTOR IS STILL BEING BUILT. IT SEEMS A LITTLE HIGH TO ME
    103mph :idea: I'd BE SURPRISED IF I BREAK 90. BUT THEN AGAIN, I DON't KNOW S H I T. ANYBODY WITH A RUNNING MOTOR GET AN ACCURATE READ OFF THE CALCULATOR? NOT KNOCKIN' IT, JUST CURIOUS.
