Thoughts on this...

Running twin turbos...
Oil feed was from the stock location, and just tee'd to feed both, the secondary, and the primary charger...

I am running the FS 2500 oil filtration system on my truck, and with the way the hot pipe is run between the turbos, the return line "Collar" of the FS 2500 is kinda in the way of the oil cap and hot pipe. (Clearance issues)

I was thinking of using the stock oil feed for the secondary turbo, and then use the return of the FS 2500 for the primary charger. Then, move the oil filler cap to the drivers side valve cover, and put the driver side valve cover "Plug" in the passenger side valve cover.

Benefits:

-Separate supply of oil to each charger.
-Should be the same oil pressure, as the FS 2500 supply comes off the oil filter cap.
-Cooler oil to the primary charger.
-Cleaner install.

Thoughts on this???

Sound like you have it figured out, i would check and see what kind of oil pressure is coming out of the fs 2500 just to make sure

Seems to me that it would slow the filtering effectiveness of the fs down to useless status?

I would also want to know if the return line has enough return to be ok,not starving the charge?

how big is a return on the fs? all pressure is equal so it will be fine.

The pressure going to the FS 2500 is what's inside the filter housing. (As the oil is coming off the top of the oil filter cap)
The line size is 1/4" both going to, and returning from the FS 2500.

I used a 3/8" SS tube for the oil supply line up to the secondary turbo. Just before it goes into the secondary, is where I installed the tee, and dropped down to 1/4".
The line I had going to the primary before was a 1/4" braided line as well.

Not to sure how it would slow down the filtering process at 30-70 psi. The primary has a 1/4" npt fitting, while the bottom takes a 3/4" drain back to the oil pan.

It was just a thought...

I may just get a bulkhead fitting and tie it back in through the valve cover itself. (I sacrificed a oil filler cap last time...drilled and tapped the fitting in the top of it...vented cap...not work so good.)

The FS is a bypass oil system no? Meaning not all of the oil is running through it, and what is is getting filtered very slowly? Wouldn't the volume of oil coming out of the return of the bypass be substantially less than the factory feed? Seems like it might starve the charger for oil, but it's just speculation...

Well I don't want to starve anything of oil.

Gonna play it safe, and go with the bulkhead fitting, and tie the return of the FS 2500 back into the valve cover, and leave the turbo lube lines as-is.

 

[motoxracer42]

why cant you tee it off again? ive been running that for a long time.

thats was my point.

the return isnt going to be free flow return now. its going to be pushing against the charger bearing. with how tight the filter is in the fs i would be worried that its not going to deliver enough oil to keep the charger happy.

remember 0psi at x gpm
increase psi drop x gpm

This sounds like the best idea IMO.

You would have to know what the pressure is coming from the turbo feed line and compare that to the return from the FS2500, which I can just about guarantee will be much less, and see if it would be enough to keep the turbo oiled. By simply relocating the FS2500 return line, you aleviate the whole possibility/problem of not supplying enough oil.

I'm always looking to improve the looks or functionality under the hood.

If there is a better way of doing it, I would like to try it...lol

Thanks everyone!
