Probably been covered before, but I'm interested to know....

What do your gauges sit at at cold start up? Then when normal temperature is reached what does it sit at? ie. idling in traffic?

Mine on cold startup sits just over 4 then when idling in traffic is just slightly over the 1st quarter on the gauge.

This could make an interesting little poll....

Ev.

RB26DETT here:

Sits on 4 ish when cold. When it heats up it sits on 2 ish. If drive it hard, with some full throttle etc, it drops right down to 1 or below.

As the oil heats up the pressure should drop. Changes will vary between oils, a low viscosity at hot oil (ie: 5w/30 or 10w/40) will have a lower pressure than a higher viscosity at hot oil (ie: 5w/50 or 10w/60). The second number refers to the oils hot temp weight.

I have found that it reads different depending on the oil level, if I have over filled it a bit, it reads higher than normal until hot, if its a bit under it reads just a bit lower, when hot as well. it reads alot higher for the same amount of less does.

Anyone think mine is too high?

R32 GTR, freshly built, n1 oil pump

cold 8 bar,

warmed up 4

driving hard between 3-4

Oil - Mobil 1... forget viscosity of it...something like 10-50 or 5-50..

About the same as mine.

When its cold, its just under 8 bar tho.

Mobil Synthetic S 10W-40

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.

      OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
