Hi = Neil, 

Great = question.   I never got a lot of great info on how much oil = flow I should be feeding to turbo.  I take the supply from the = oil outlet on the top, spark plug side of the front side housing.  = I run it through an electrically operated shut-off valve in case the = turbo fails in flight.  I originally used a #30 hole in a = plate of aluminum as a restrictor.  Later I decided to omit = the restrictor and just rely on the shutoff valve and AN-4 = plumbing to provide enough = restriction.  

 

I = have no idea if my system is correct, and I do get quite a bit of oil = seepage and mist coming from the area of the turbo, but at least the = most recent turbo has about 700 hrs on = it.
