I am using a GM performance parts oil distribution block just above the oil filter. I have a -4 line that goes to a "T" and then a -4 line to each of my turbo's. I ran the engine with the turbo off so I can see how much oil is pumping out and it is just a small steady stream. I thought it would be a lot more. It doesn't seem like you would need much to lube the turbo but just wanted to make sure that something wasn't wrong.

I have 60lbs of pressure while driving. 40lbs at idle warm, and almost 80lbs when I get it into full boost of 15lbs. Do I have enough oil feeding the turbo's?

Thanks in advance.

i have the same set up 4an from filter housing to a t then 4an to the turbos and a 12an return to the pan

Del that's about what my engine is showing with only a single 4an feeding one turbo. If it make you feel better, you can use the oil pressure sending location and feed one turbo with that, so you dont have to divide a single location

-4 feed and -10 return is usually what everyone runs. You're fine.

Okay. The size I thought was okay. I just wanted to make sure that a small steady stream is the same as everyone else. I thought it would be pumping oil out but it is just a small steady stream. Kind of like when you pour a quart of oil in and at the very end you get that little bit more that is just a very small steady stream. Just want to make sure that it should be really pumping it out or something.

Thanks.

gotta remember pressure is resistance not flow. so even if the motor is seeing 100 psi oil pressure doesnt mean a open hose is going to look like a fire hose spraying. the small space in the bearings is what makes the resistance and pressure

What about a -8AN return on a D1 blower? Is that good enough?

i understand what ur saying op cause if its that little coming out then whats the point of a oil restrictor for a ball bearing turbo if it comes out like so? is it maybe the gm tapping block that is causing this? im about to put mine on and this just makes no sense..

I think it makes sense now. I am checking at the open end without the turbo on. Like they said, with the bearing and the resistance it will have the pressure to lube the turbo.

Thanks for the input everyone. If anything happens with the turbo I will update this thread.
