turbo oil drain

Garrett says .040 and 45 psi at highest engine RPM. IIRC Holset recommends 2 lpm. Its in a Holset rebuild pdf.

"...The minimum oil pressure when the engine is on load must be 210 kPa (30 lbf/in2
). Maximum
permissible operating pressure is 500 kPa (72 lbf/in2
) although 600 kPa (88 lbf/in2
) is permitted during
cold start up. Under idling conditions pressure should not fall below 70 kPa (10 lbf/in2
).
15. Recommended oil flows for the turbochargers are 2 litre/min at idle and 3 litre/min above maximum
torque speed..."
