Oil tank welding project

[slow94]

So I have an idea for a closed loop oil system to feed my turbos and I decided to fab up a tank that I can use. It is a little over 6 quarts in capacity. Dimensions are 12x12x2.5 inches. All 10 an fittings. One on bottom will be the feed to the exa pump, the one on top will be a vent, and the two on the sides at top of tank will be the drains. Turns out turbo werx sells a regulator for the bottom of their pumps that turns their pump into a feed pump that will hold 40 psi pressure and can still scavenge oil from a drain. My plan is to fill the tank to just below the drain fittings so that no matter what the tank can never be too full. That way the tank is always maybe 3/4 full while the pump is running. I also welded in some baffles inside the tank to help with sloshing.

What about cooling, for extending driving periods?

Fab job looks really good!

Well from my research I actually need to worry more about getting the oil up in temperature. Probably run a much lighter weight oil in this system than the engine to compensate for it. It looks like the turbos by themselves won't get the oil nearly as hot as the engine does. Also, "extended" drive time for me would be something like 30 minutes so probably never need a cooler. However I will monitor it and assess later. And thank you, I like to weld aluminum.

That looks really good! Did you put a bung in for a temp sender?

I haven't but I suppose I could always just weld one in for future use. My plan is to get it running and take laser temp readings in varying positions. My guess is it would take a long time to reach same temps as engine oil.

I like to tig stainless, now especially since put a reader lens in my helmet. Never tried aluminum though.

Stainless is fun too, just a bit more challenging. Aluminum to me is pretty easy once you get the hang of it.

Looks great man! When I was thinking about a remote set up I contemplated mounting a reservoir in the bed and gravity feeding the turbo. Then pumping back to the tank. But I like this set up better since you don’t have to cut the bed and out of site /way is always better.

Are your turbos water cooled? If so, the oil won't ever be over 180-190 degrees, especially with that volume.

I chuckled at the "reader lens", especially since I recently had to get reader safety glasses to be able to see numbers on prints in the field. Ah, getting older is so much fun.

No they are not. Just basic journal bearing turbos. I have done a lot of reading and it seems the biggest concern with most is getting enough heat into the oil so it flows better. I'm going to call precision and see what oil they recommend.

Well precision didnt have a "set" recommendation other than to use a somewhat lighter weight oil than what is in engine (10w40 Penn grade). However he did say that a synthetic would be better. So, I think a 10w30 or 5w30 synthetic would probably be just fine. A lot depends on actual oil temps but that should at least be a good starting point.

Check with TurboWerx, too, see what they recommend for their pump.

Had to go a different route now that I have turbos in place. The first tank I could have made work but this one is definitely a little better for my application. I also added a dedicated full and drain port.
