    Default How much HP?

    How much HP to turn a 9.5" SS impeller and DPS inducer 6000 RPM.

    The only chart I can find only shows 4800 RPM. anyone here care to offer their thoughts.

    RPM is pointless without knowing intake pressure. You can turn a AAA 9.5 impeller 8,000 RPM if the pump is not loading water properly. And a chart will tell you 1,600 HP

    In the process of getting the pressure readings, hopefully have them this week just kinda fishin for a ballpark idea on where I'm at with this thing. Got a gauge, need to pick up a hose and get it together, Im still thinking this loader (V blocker I think ) is the wrong one for this boat. Im thinking there is too much blocking going on LOL.

    I recall James calling it a 4A I really don't know. but it has a lot of meat on the fins. James could answer that question better than I could.
