Electric oil pressure gauges

[NHerron]

Right on, I might try that remote stuff out, considering these Montana roads...

Here's mine right now.
It goes from 3/8NPT (should to BSP) to 4an via adapter, 90* 4an, 4an pressure sensor adapter (1/8NPT port), 4an oil restrictor, oil feed line to turbo. The sender is a two wire sender.

Not sure on the interchange, I could test resistance at various oil pressures to see where they are at, for reference.

Shouldn't you have the restrictor before the sender so you know what pressure you turbo is seeing? Unless I am seeing it wrong.

If you're trying to measure turbo oil pressure, then yes. If you're worried about engine oil pressure, then no.

What Brian said.

From time to time I think about sticking the sender after the restrictor since if the line breaks/comes off/etc it will show up instantly on the gauge, whereas the other way you wouldn't know until the entire oil supply is on the road or from an 'oil on the manifold' smokeshow.

Got it thought you were measuring pressure to the turbo.

Question: Could you tap of the stock sending unit to a gauge to get engine oil pressure?

I ask cause I want to the same setup as NHerron but going to put the unit after the restrictor so I know pressure to the turbo.

 

[NHerron]

Yup. The bigger ports are 3/8 BSP and smaller ones are 1/8 BSP. You can get brass NPT fittings, make sure use a bit of pipe tape. NPT & BSP is extremely close but not exactly same threads. You will be fine with a bit of pipe tape.

I understand how to run the gauge for my turbo pressure.

Just wondering if I could just run a second wire off the stock unit to a gauge and get an accurate measure.

I wouldn't do it. I've seen my stock gauge working and there's no way that sensor is accurate enough to get pressures off of.
