Topic: Who has a oil pressure gauge installed in their car?

[Graywolf]

I am interested in finding out how many of you have installed a oil pressure gauge in your car. Secondly, has anyone noticed a drop in pressure during Drag,Autocross,or Road racing etc. Since I am one of the unlucky that blew a engine last year [piston] that was not covered by warranty, we need input to help prevent engine failure. It is well documented that piston failure occurs[oem pistons suck]

I have a oil pressure gauge in my car and it stays steady around 158

158 psi?

[Sol Asylum]

Per GM's shop manual the LNF should have a min oil pressure at 1000 RPM of between 50-80 PSI.

[IBDRINKEN]

shit I def mistyped that. I ment 94 constant

That's a big "mistyped" mistake, numbers don't even match for a mistake... "158" - "94"

And THEN there is 50-80 psi at 1000 RMP. Coolness. 

[IBDRINKEN]

I was looking at the oil temp instead of the pressure...

[Sol Asylum]

Fixed that typo for you Bob, at least I had the right letters just in the wrong order.

I like how the minimum is a range.  If you have 85 psi at 1000 revs is that too much for a min?

[Graywolf]

Well i just replaced the sensor on my gauge . At idle 8 to 12 lb,then it goes to 38 @2600  43 to 45 @ 6000rpm. Since the sensor I used was not the same diameter as the original that came with the gauge,I'm guessing the gauge is a 0 to 60lb and the sensor I know is off a 0 to 100lb gauge. So I know this will make the numbers off,sorry I am not going to spend another $35 to put the correct one on it.This is the pressure off the oil line going to the Turbo

That sounds a bit low for engine oil pressure, manual says 50-80psi at 1000rpm, for turbo oil pressure its ok.

[Graywolf]

Agree Shabby ,but I have never had an engine oil light go off. Using the wrong sensor isn't helping matters. I would think the pressure going to the turbo is the same as the engine but I might be wrong. Also of interest is the fact that it takes 3 to 5 minutes for oil temperature to catch up with the water temperature. So please make sure your engine is well warmed up before you race.

Where did you place the sender for the oil temp gauge

[Graywolf]

I put a T connector off the oil line going to the turbo and ran the oil line to a electrical oil pressure sensor

[MGar]

I do know that most turbos require a restrictor somewhere in their incoming oil line, especially if they are ball bearing turbos.

[Graywolf]

MGar, I wondered about a oil restriction for turbo but your the first to mention it. However,I would think it would be built into the turbo oil inlet.

[MGar]

They are typically in the inlet.  However, I don't know in our particular application if that is the case because I have not gotten into it yet, as my turbo has yet to fail.
