Ayin Kafin Yan My Nutsack has drama issues- Oil Pressure beleagurement
 

My oil pressure is around 15psi hot. When I rev it up, for anything over 4000rpm, I do not get more than 45/50psi of oil pressure. Pretty much flatlines from 4000-7000rpm

What the fuck could be the problem?

sounds normal for non HLAs.

I thought you were supposed to see 10psi per 1000 rpm?

Also FWIW I have the oil pressure gauge mounted on a Tee off the block which also feeds my turbo.

Ohhh so that is why all the NAs have so much oil pressure.

Sounds low-ish. I had 22-23psi at idle and ~60-65psi at WOT. Cold was like 75-80psi. $120 solid state sensor.

How old was the oil pump that was used? The spring controlling the oil pump relief valve could be slightly out of spec. Or you could be low on oil. My oil pressure would read low when my oil was running low.

Oil is freshly filled rotella synthetic 5w-30 chock full of 4 quarts.

Oil pump had about 3000 miles on it and ed (dyno shop) checked clearances before installation. It is a miataroadster billet gear. I gave them a call and apparently there were no reported problems.


Let me check the connection on the sensor itself. Maybe the wires are frayed or some shit

Are you using a real gauge or the oem gauge? I'm going to assume a real gauge and suggest that maybe the full synthetic rotella has something to do with it, especially when hot. It's really 'slippery' and pretty thin after everything is heat soaked.

A "real" digital gauge. Yes, I watched my oil pressure drop from 40 psi cold (60F) to 15 psi (200F) hot.

probably a leak in your alternator/frame rail/insert issue here.
