Rack and pinions use closer to 1,100psi and steering boxes use between 1,000psi down to about 850psi.
Flow through the steering boxes is some where around 3 to 4 gmp at that pressure.
Dont know how much flow racks use.
To produce that much flow and pressure we are looking at needed between nearly 2 to 2.5 horse power to maintain it.
The good news is thats only like 5ft.lb of torque, the clutch I want to use can handle many times that.
