With the FeedLine Caped. I get Normal oil pressure ~70 cold

With feedline Connected to Turbo I see 35 Cold

Has anyone seen this happen?

This is a Turbonetics Ceramic BB t3/t4B

 

try a restrictor

 

yup, ball bearing turbos need it.

 

x2.
I have a Turbonetics ceramic bb T3/T04B and my oil pressure is fine without a restrictor, but it's on a VW motor

 

where are you taking the reading from? if the sensor is inline with the feed line you could see decreased pressure from the turbo. the turbo essentially pulls pressure away from the sensor. doesnt necessarily mean the rest of the motor has low pressure though

 

I thought it was just the Garrett/Precision Turbo's that needed a restrictor, didnt know Turbonetics required it too.......

I run my feed from the same spot that my oil pressure gauge is, and I see no difference with the line flowing or capped, running a -3 line and .035" restrictor.

 

Retrictor did not help

Retrictor-low oil pressure
Oil Feed in bottle=Low oil pressure
Caped off-65-70 off the bat

 

Turbo GT ball bering got already intern restrictor

EDIT I HAVE TAKE THE TIME TO TAKE A PICTURE OF MY TURBO

 

^^^^^^^^^^^^^ its not your turbo.. jesus christ

 

we are all aware of the factory GT built-in Restrictor, however it is pretty widely known that you should run an additional .035" restrictor because the GT's dont like alot of oil pressure.

 

Not about the OP's issue, but about restrictors........
