Oil pressure at cyl. head and HX35

[stunt2]

I have pressure gauge at OFH (unported) and seeing ~18 psi at hot idle @800-850 rpm (sometimes dips to ~8 psi when the cams lope but for a half of second)
and max ~90 psi at redline. on cold it sometimes overshoots to ~100psi.
no balance shafts but do have oil squirters, using 5w-50 oil

the reason im asking, I've just installed HX35 but unfortunately my exhaust manifold style doesn't give me enough clearance to install tee fitting at turbo oil inlet to hook up pressure gauge. hate saying it but I have to guess what my oil pressure can be at turbo inlet. or at least I can hook up the gauge at the side port of the head but still guess what the pressure could be at turbo

feeding it from stock location with this line EXTREME PSI : Your #1 Source for In Stock Performance Parts
and draining with custom true 20mm inner diameter hose, all the way from turbo outlet to oil pan (oil pan hole still needs to be enlarged but will be done shortly)

sorry for long post guys. any suggestion is greatly appretiated

Get pressure at the source.
So if you are trying to find out turbo feed line pressure and your fed off the ofh, put gauge in line closer to the ofh you'll have room

I feed from the head, from stock location with banjo bolt

so if I hook the gauge to the another head port I'll have more or less accurate view about what's going on at the turbo inlet, right ?

 

[Archer Fabrications]

No it has to be the same line.

 

[stunt2]

I know that but read the first post

You should be feeding from the ofh not the head with a holset.

Yo. Won't get enough consistent volume from the head at all.

You would really be better off buying a tee fitting, plugs for the OFH port and head feed port as well as second line like you have now to hook your pressure sensor in-line. Then you will be able to swap between the two spots as needed.

Here are your options if you insist on trying to use a related head port:

cant't quite understand the post above

let's say this way, tee fitting must be right at the turbo oil inlet to get accurate pressure reading after oil feed line. doesn't matter line comes from head or OFH. right ?

and as I've described I have no clearance (in height) to put any tee fitting at the turbo inlet and then put feed line above it too, as one of the manifold runner is too close and can't accept it

 

[LandSpeed-DSM]

No, sensor just has to be after any filters or restrictors. If you have none, you could adapt the fitting off the head and run the line from the adapter.

You should post a pic of the manifold and oil inlet to the turbo.
