Can I run hydro boost on my truck if I am already running a hydro assist steering? Seems like it would max out the stock chevy pump??

if i think what your asking is " can i have power brakes and steering off the same power steering pump?" then the answer is yes. thats the way its made to work. if its a hydro boost pump, booster, and maybe even steering box.

I have a west texas off road hydro assist on my cross over steering. My box came from them also the pump is just a standard chevy unit I was just wondering if the chevy hydroboost would be too much since I am already running a ram on there.

I run p.s. , hydroboost, and a 12000lb hydraulic winch off my gm ps pump.

I've heard that ps pump off of a diesel works the best.The valve is different, its made for low rpm witch is what most people using hydro steer need.

From the research I've done the saginaw pumps are all basically the same. The difference is in the preasure releif, and flow gpm. The diesels just use a larger diameter pully to offset the low rpm of the diesel.

one thing to think about is using a P/S cooler........pressure shouldn't be a problem but heat will be, plus you will probably also need a reservoir

Wouldn't a larger pulley make it turn slower yet?

I don't think there is a bolt in. I took one from an 87 and made the firewall bracket fit, then redrilled a hole in the brake pedal, this took a couple of tries to get the feel and stroke right. Will be doing another one soon out of an 89 p.u.

MY diesel sub has a remote resevoir, but otherwise the pump looks the same.

Not a direct bolt in but here is a link to how I did the conversion.
