I'm setting up a truck with 12V electric steering, the 12V's run a hydrualic pump. Question I have is about the hydrualic flow aspect of it. I'm using the factory power steering box (78 4x4 Ford Truck) and have found a setup that will work for me on Northern Auto Parts, The PSI is adjustable from 1000-2500psi, so no problems there, but it only flows 1.4GPM, I'm not so sure that's enough, the truck doesn't need to steer a lot, very little actually, it's a pulling truck, so it would need to steer about as much as a drag car does, but my front tires are gonna be pulling be back and forth, plus I'll have at least 1,200lbs of extra weight on the front, so it needs to be effective. I just don't want this thing to have a "loose belt" or "-20F degrees" effect all the time. I'm kinda thinking it needs to be at least 2GPM or 2.4GPM.
Any suggestions, input or information on how much a factory power steering pump flows would be helpful. I seen a few setup's like this on modified diesel trucks, but it's more common for modified gas trucks to have it.
