I know this has been asked a million times, and I did search both here and other sources. I cant find a published number anywhere. I have an electric gauge with my sensor located before the bypass, right under the filter. Cold starts read 80 psi at idle going down to 35 psi hot, and cruising oil pressure seems to be around 80 and WOT can see 100 or maybe more. That seems high to me, but I realize many place the sensor at head or back of block. Is there a published range in tech manual?

i don't know of a specific number but i am seeing some oil pressure gauges going up to 150psi now. they used to go to 100. the closer to the oil pump, the more accurate reading you're going to get on how healthy your oil pump is. as long as your car is stock and it's not pushing oil past your turbo seals then id say youre good. i would think the turbo seals would be the weakest link to hold oil pressure.

i know my eclipse is about 70-80psi cold start, about 10psi hot idle. cruising is anywhere from 50-80 depending on how fast im going.

I had my sender off a 3 foot line on the block, into a small aluminum block where I had my sensor. my pressures were about 20-25 at idle. Should be 30 at 2k rpm. 60 plus when cold in winter, driving was like 55 psi. wot went to about 60. having 100psi at wot iv never seen, unless u have a rotary engine

If you put the gauge close to the pump you will see 80-100psi while driving, in the head you will see around 20-30psi driving.

I know this is an older thread but Tom is still here so I thought I would check in. I see pretty much the same pressures Tom mentioned above and I have my pressure sensor connected to pretty much the same port, specifically the port furthest towards the filter housing. I am using the LNF piston oil squirters in my block. Are the pressures described above OK? Everywhere else I looked made it seem like these sort of readings are way low. My bottom end doesn't have that many miles on it and my top end was recently refreshed. I have the machined timing cover from ZZP though I did swap in hardened oil pump gears.

I actually built an oil pressure block to hold the stock sender, and the gauge sender. block is connected via an4 to where stock sender used to be screwed in. the block is bolted to the vac tank bracket I modded to work. I now see 40psi cold start, 28 to 30 psi idle, and 7o psi driving normal. never really look at it on a pull so idk what that is.
