I was wondering. If you had a seperate oil cooler for your turbo, in a closed system, say one or two quarts of synthetic oil. Could you run it like that while bypassing the main oil supply? I know you would need a pump of sorts. Electric or something drivin off the engine. I thought with a setup like that you could better control turbo oil temps, pressure, and cleanliness. No sooty oil into the turbo. No scorching hot oil from redline driving. You could run a oil weight that might be better for the turbo but not right for the engine. Would you need a filter system on somthing like this if it was closed loop?
Just throwing it out there for comments.
Benefits? Drawbacks? Ease of implementation?
The biggest fear would be if whatever pump system you used failed. Kind of hard to have that happen off the stock gear drivin oil pump.

i would say why not have a heat exchanger to heat the oil. it would take a very long time to heat the turbo oil on a cold day. the oil helps get the turbo heated up to operating temps.
i'm going to be running an fs-2500 bypass filter myself. no more sooty oil, but the oil temps will still be high.
Stock turbos last for 200K+ miles using oil from the engine. Benefits? Maybe if you want your turbo to live through two engines.
That sounds like an idea, but the reward might not be worth the trouble. My Powerstroke (I know... different vehicle) has 286k miles drinking the black stuff from the crank case and I've never had any trouble *knocks wood* besides the bolts holding the turbine housing to the chra backing out, but of course that's totally unrelated.
I'm keeping an eye on your buildup. Looks like nice stuff.
If I remember correctly, the early Aerocharger VNT turbos had an oil sump, and I think they even used a wicking oil feed system.
Now thats the yankee in ya!
