Isolated/Remote oil system for turbo

[farmtruc]

Hey guys, I was thinking last week, and I'm not too fond of the high oil pressure the engine feeds the turbo for the sts kit and the long travel it has to take. I was thinking of inserting a reducer in the feed line to cut down on pressure and volume, but I was thinking of a stand alone system for the turbo.
I guess it would keep the oil very clean and cooler than what the engine runs at.

-- Does anyone know exactly how much psi and flow a turbo needs in order to stay cool and operate properly?

I'm thinking it just needs a decent flow of oil. Say, 10psi or so, just enough to cool and cover the rotating parts.

What parts do you think I'll need. I can put all this stuff in the back of or under the bed.

I'll need about a 2qt resovior, a trans cooler with a fan, return and feed line, and a pump.

-- What kind of pump, maybe a low pressure/low volume electric fuel pump, would it pump 0wt. oil?

-- What are the advantages of this? Disadvantages?

thanks for any input!!

i was thinking bout that myself when i had my oil pump problem...shouldnt be hard to do at all...a small tank, a cooler of some sort,a pump and some hose and wire.

Why not use one of the pumps that comes with the STS system? Are they major expensive?

Where are you going to mount the trans cooler? You may not need a fan if you get ennough air across it.

I think it is more flow rather than pressure. I don't think the turbo will restrict the flow.

I was checking on oiling for the twin turbo set up I want to do.
I found out that each turbo only has to have 20psi to run properly.(w/ restrictor)

Me and Billy have discussed a stand only oil system before. We think you would have to have a pump to feed and a pump to return. You could do w/ out a pump to return if the turbo was higher than the tank. But thats just my thinking.
The good thing about having a return pump is you could push the oil through
a oil cooler.

The pump will have to be strong enough to push through a filter when oil is cold/thick. Will also have to be able to adjust to flow demands at different RPMs. Put a fuel pressure regulator on it to regulate the pressure to 20 psi at all RPMs?

Allen, I have thought about this before too.
If the feed pump was wired into the fuel pump so when you turned the key and the fuel pump primes, the oil feed pump will prime the turbo. This way, the turbo will not spin at all w/o fresh oil going to it.
If you used some kind of restrictor valve, it would ensure the proper flow w/o having to use a regulator. You could also use a check valve like STS uses. It normally has 20 to 80psi going to it, but I think it acts as a restrictor also.

Why woud there be any such thing as cold/thick oil? Anybody running a turbo (I've got one in my car) should be using only synthetic... and synth flows superbly even when it's well below freezing.
At any rate, I've been using only synthetic in naturally aspirated and forced induction cars for 20 years. No more dino oil except for initial break-ins.

Thanks for the suggestions!

What about pulling the oil through the cooler?

SO, the turbo will be mounted higher than resovior, then dump into the resovior, then the pump will suck the oil out through the cooler.

Jus tgetting some ideas, not sure if I'll really do it, but it seems it might work.

Will a low pressure fuel pump, pump enough ZERO wt. oil for the system?

thanks,
