power steering pump as a secondary oil pump?

is it possible to use a power steering pump to run oil through a secondary filter / cooler on a car,or will the pump not be able to handle engine oil?

The pump will handle engine oil just fine, but the rest of the system probably won't like the 1800 psi it supplies

It could still be used... The first rearend circulating pumps in Nascar were power steering pumps modified (just changed the relief pressure) to circulate the oil in the rearend for cooling...

But I guess the main question is why would you need another pump...? The reg engine oil pump produces plenty of flow and pressure to run through a cooler...?

In addition Nascar and other forms of racing they no longer use internal oil pumps but use the multi stage dry sump system to minimize windage in the crankcase (oil being whipped up into the crankshaft which robbs HP)... Oil does not sit in the pan it is kept in a large tank located behind the driver normaly... Also the pan is very short because there is no need to hold oil, this allows the engine to mounted lower for a better center of gravity and areodynamics...

Bumpstick makes a good point. The stock oil pump in most engines is sufficient for most uses with a hi-volume pump being overkill in many builds. Additional oil or pressure is simply not needed in most builds.

The issue of windage and aeration is a problem that affects many engines and more oil would make that problem worse.

do you need a secondary oil pump ? or will a oil cooler work ? the Suburban we just put together has a oil cooler on it. its kinda trick and I like it.

well actualy, the stock pump offers just enough pressure / flow for the engine itself, and ill be adding a turbo and piston oil squirters as well

i was thinking of putting a fitting in the side of the pan, throwing a screenover it inside, then running the lines to the pump and out toall the extra stuff

since pressure is a matter of restriction, carefull arrangment what gets fed how could keep pressure in check

Power steering pumps are also not self-priming which is why the reservoirs are always above the pump. Just plumbing in a line at the pan might work, but it might never suck any oil if the pump is above the level of the oil.

You're right about pressure being a function of restriction, but we're talking about the potential for nearly 2000 psi. One tiny fleck of debris for a split second could be disastrous. If you design a system for free flow of about 20 psi, you'll pump all the oil out of the pan in a matter of seconds with a power steering pump.

The aftermarket has plenty of electric pumps that could supply 20 psi of adequate flow for your stuff. Or just step up to a HV pump in the stock location and it will be sufficient (and more reliable than an additional pump)

there is no HV pump available for the engine in question. hell there are hardly any stock replacement pumps available.

priming shouldnt be much of an issue, i was thinking of mounting it super low on the engine anyways, as everything except the turbo will be frame rail height or lower

im trying to do this project uber low budget, while maintaining reliability, and while experimenting some

I'm all for experimentation

I think if you properly valved it, plumbed it completely independently from the other oil system, and maybe added a bypass for safety, it should work. Sounds like more work than its worth, but your theory sounds plausible.

well ill already need to:

run asupply and drain for the turbo
supply and return for the cooler, with a thermostat.
i might have to run remote oil filter as it is ..

so im looking at making a bracket,doing a supply line, adding the squirters, adding a second filter, and running a presure releif valve someplace

a days work

plus i love the idea of doing something noone in the area thought of ... and being told it wont work, when it already does work

It would be REALLY HELPFUL if we knew what kind of engine you are working on...........

What kind of volume is a power steering pump capable of? If the pump is capable of 1500+psi and you set a relief at about 20 psi what do you do about the extra heat created by the oil flowing out of the relief valve that will be constantly relieving and sending oil back to the pan? Are you even going to gain anything by installing the pump or will the cooler and power steering pump cancel each other out when it comes to adding and removing heat?

As far as the pump sucking the pan dry; you could install some kind of orifice after the pump to limit flow. But again you may end up raising pressure and heat if you did that.

Just my thoughts.
