My father is a hydraulic engineer and when I ran these questions by him he debunked most of my ideas. The pulley would only help at idle, as soon as the engine speeds up a little, you will be right back to where you started. I showed him the flow limiters that some of the companies sell and he said that this would lead to cavitation and over heating the fluid. There is an internal bypass pressure regulator built into each pump. He showed me where you can open it up and add shims to increase the pressure, or cut the spring to decrease the pressure. I ended up getting a pump designed to be the correct volume and pressure for my steering box. It is silent and works perfectly. Find out from them what the parent vehicle is for the rack and get a pump from that car. More than likely a saginaw II pump if it is the center take-off rack. That is the default pump on most new cars form a lot of manufacturers.

I hope this helps.
