TibbyTurbo

Hi Everyone, as some of you know I'm back Turbo again for about a Month now. I could already tell that this setup is working much better than the last and everything is working pretty well so far. I have built in restrictor on feed flange, before the restrictor the oil pressure is at around 10 psi at idle and at WOT I only get 50 psi, I have read that as long as you dont go over 70psi on the turbo it is safe, so should I remove my restrictor or keep it? Also is 10 psi oil pressure before restrictor enough pressure at idle?



Here is my oil feed setup, oil sender is just above the feed flange:

Stocker

That's 10PSI to the turbo, or 10PSI right off the oil pump?

TibbyTurbo

10psi to turbo but that pressure is before restrictor I dont know how much pressure after restrictor.

Maximum Boost says 5psi minimum at idle for most turbos.

Any Idea what would be an estimate pressure after going thru a 0.1mm restrictor from a 10 psi? I have read journal bearing turbos do not need restrictor as long as you have good drain and the as long as the pressure is not over 70psi.

I'd just ask the manufacturer, where's the oil feed tapped?

TibbyTurbo

Its tapped from the block

leave the restrictor. again, your fine.
