During all normal driving the pressure in the PS system is very low as the fluid merely circulates until assisted steering action is called for. The system will only approach 650 psi when yanking the wheel out of a deep rut or some such and the pump essentially dead heads against the power cylinder piston. Its a little hard to see how a hydroboost can share with that. Hit the brakes on a straight stop and there is almost nothing for the hydroboost to work with as it is all bypassing through the steering control valve.


Thanks! I appreciate your reply! I believe that to hold true of all hydraulic systems. Once you load the hydroboost by pushing on the brake pedal, pressure would increase as you're working the pump with restriction. The hydroboost is first in the circuit. But unfortunately the Packard pump is half the gpm and pressure needed for a hydroboost. I prefer hydro over vacuum and they are psychically smaller, making it easier to install in tight areas. Plan B, seeing how big of a vac booster I can fit. Likely using the crotch vent opening.

Any thoughts on the strength of the factory PB pedal pivot mount? To get a 4.1 ratio I need the booster rod hole to be 2.3" down from the pedal pivot. That will add a lot of leverage to the pivot.


Thanks,
Earl
