What is the normal pressure in PSI for a turbocharger?

Question

I have a t/3-t/4 turbocharger that I am using in a gas turbine and I'm not sure what I should set the oil pressure at. I have been setting it at 80psi and as it warms up it drops to 60 where I originally wanted it. I think I may have blown the seals out because it leaks oil really bad inside of it. Is 35 or 40 psi too low? It might cut down on the oil leaking. BTW some oily and dirty looking stuff came out when I blew it out, looks like hair, but I'm afraid it may have been the seals.

Answer 1

it could be as low as 4 lbs, or in the mid 20 lbs +.  depends on the application.
