Parts-- Astovan HB, PSC P/S pump, 4x4x4 ported P/S box
Symptoms are the effort it takes to turn the strg wheel increases with the rpm when cornering... -up to a point as I haven't tried turning a 90deg turn at 4K rpm.
So... If I am sitting at a stoplight let's say or in my backfield idling I can turn the steering wheel with its normal amount of effort. If I accelerate as I'm going into the intersection and turning either left or right because it doesn't matter, then the RPM's at my engine might be higher and there is a noticeable increase in effort to turn the steering wheel and then it takes the same amount of effort to turn the steering wheel back to center..
I slapped a pressure gauge on the side of my ported box and as I'm turning the stg wheel the press is at 1350 at idle. If I increase the rpms the pressure is still at 1350psi and I can only test this while turning left since I dont have any AN fittings to splice into the system elsewhere. Although tapping into the left port does determine that myps box seals aren't compromised since I have zero pressure on the left port when turning the wheel to the right...
Is the bypass or porting in the AtroVan HB unit not allowing enough flow thru when putting more demand on
Possibly the box? Its always taken a Herculean amount of effort to turn the 37"s or 40"s off road...ever since I got it...
Ideas?
I have the ram disconnected so thats out of the equation
