[oil pan 4]

I am not using hydro boost.
From what I can tell the power steering pump by passes through the inside of the steering box when you don't need it. Only developing something like 150psi, but that pump generates so much flow it still soaks up a lot of power.
I found that it took 200 watts at idle speed to turn the power steering pump when its "bypassing" but it took over 500 watts at 2000rpm.

Plus in my infinite wisdom I ordered the wrong pump. Its only rated at 0.35 gpm. Not even worth trying. I knew something wasn't right when that pump showed up with size 4 ports.
I think what I really need is a single acting hydraulic power unit. I think bailey hydraulics has the perfect one, 2.1gpm, internal relief set for 1,400psi and normal -6 OR ports.
I don't have to have the "single acting" capability. This will allow me to turn off the pump and energize the single acting solenoid that will instantly form a bypass around the pump. It may make turning the wheel easier with no hydraulic power.
