    Thomas for a 400+ HP turbo setup you will need that impeller. The 4 blade won't have near enough pitch.

    why not try 15/22 4 blades or 15.5/22.5 3 blades,, im use 3 blades 14/19r and 15/19r to stock limited only
    i think stock pump cannot pushing over 3++hp,,, bearing and pump can broken,, if not broken ur power still under 3++hp
