I don't have a Backdraft, but I do have power steering in an A&C. Previous owner installed a GM power steering pump with a Ford Rack. I think Ford power steering pumps operate 1000-1200 psi and GM are 1200-1500 psi. I don't remember the exact numbers, but that is in the ball park. So do not make that mistake. In this light of a car you can steer it with your pinki finger, and you cannot feel the road.

A fellow that comes to the London Cobra show, who loves to run the auto cross, has power steering in a FFR. He installed an adjustable by-pass valve in his car. When the pressure exceeds the setpoint (a spring loaded relief valve design) it dumps fluid to the return line. Last I talked to him it worked perfectly. He dialed his PS to exact stiff/power level he wanted. I will install one, when I get around to it.

If you put PS in a car this light, I highly recommend installing the valve while your at it.
