Inliners International Forums General Discussion Blown and Injected Dedicated oil supply

Has anyone used a dedicated oil supply for a turbocharger?

Separate oil, pump and filter?

I've heard of some trying it with home brew rear mounted turbos (like a DIY version of the STS setup).

Rumor has it Weldon makes an electric pump that works well in that situation.

At higher temps I don't know.

I was looking to remote mount a turbo, but didn't want a separate oil system, just a scavenge pump, heard about Weldon after I had bought a different pump.


Project went another direction and I didn't actually try that.

Frequent semi-separate oil system:
Feed line comes from the pressure sender etc. as usual, but the turbo is too low to drain into the pan. Solution: Shur-Flo 12 volt pump (less than $100.) drains the turbo up-hill into the pan.

I plan on just using a dedicated oil filter for my turbo.

Sorry it's not answering your question.
I do have a separate water cooling system for my air to water system & it seems a bit complex (not the correct word)but it does add a lot of extra weight as compared to a air to air intercooler.

Gary,

I don't know of a completely dedicated oil supply, it would need a reservoir large enough to allow the air in the oil to seperate before it is pumped back into the turbo.

Many have used a simple oil sump with a pump to return the (oil-air) mixture back to the oil pan. This system is used on the rear mounted turbo or when the turbo oil drain is lower than the oil level in the pan.

This thread raises some questions of a general nature regarding turbo applications that I have wondered about while comtemplating my own turbo build-up. Does anybody have any hard data to answer these questions:

Q1: How much oil do turbos need? I know this is application specific to some degree, but is the answer gallons-per-minute or gallons-per-hour. Some turbo oil lines I've seen are -3 or -4 AN size.

Q2: What are the heat rejection requirements necessary to cool the turbo oil?

Q3: Oil aeration is mentioned. What causes oil aeration in oil going to turbo bearings? I would not have thought this to be a big deal, especially on a singularly dedicated turbo oiling system. What am I missing? I know most NASCAR rear axles use singular cooling pumps and radiators and I never heard of aeration issues back there, even with gears and bearings whirring about.

Thanks for sharing your data with me.

Just wondering if there is a problem using the engines oil system?

Cars have driven hundreds of thousands of miles using the engines oil.
My Bros car had driven 230,000 miles with original turbo, & it still did not fail, the engine gave out.

Some folks don't feel comfortable pumping their engine oil to the rear of the car for the turbo. So they put in a small system for just the turbo in the rear.

He never said where the turbo was going to be mounted. Even if it does have its own dedicated oil system, it still will need to be heated to flow and lube properly just as the engine oil is or the turbo will fail. Anyway just get single stage dry sump pump and a small tank that holds about 3 quarts of oil and plumb it in, should be all you need to do. Put a Moroso heater on the tank to warm the oil....
