Electric motor to turn water pump

Well the goal is to be at about 5500 to 6000 a the traps. I put 4:30 gears in it and it has a roller cam. Trying to get her some seat time to get comfortable with the car and the procedure before we start going faster. I guess I should look into this. Question how do you run the alt and power steering? Won't that belt interfere with the electric water pump system? I could use some picts. I know that I shouldn't be running power steering but she needs it for now.
