What is the best place to read oil temp/pressure in a turbocharged engine; sandwich adapter, galley or drain plug sensor?

Is it hottest in the turbine side bearings and cylinder walls?
 
I put one in my 91 318i just for fun, it was the VDO drain plug sensor.

Even in the hottest use, it never goes much above 160F. I don't think it is accurate. Perhaps if it were longer.

Id make sure it was someplace where oil was flowing over it. Can you put a splitter at the oil pressure sensor port and install there?
 
Without an oil cooler, sump temperature is the "starting" temperature for all of the temperature rises through the oiling system...bearings will be 10C hotter on exit oil temps, big ends a bit more, oil draining back from piston squirters higher, chain oilers about the same.

Long as you know what it is measuring, you can learn from it.

Pressure is interesting...after the filter tells you what the engine actually has available to it.
 
Galley plug...

There is a pressure switch already there, if pressure falls below a certain point, your idiot light on the dash comes on.

Oil temp is really not needed...
 
Edit - your running a turbo,
so the oil line running to the turbo would be a good place for pressure sender
and from the turbo for temp sender

On my turbo I have a sandwich adapter. The pressure needs to be at the OEM location after the filter. On a sandwich adapter it will be before the filter. If you have an oil cooler the temp sender should be before it.
 
Are oil press/temp gague packs sold with a combo sensor that replaces the OEM oil pressure switch at the block, and supplies all 3 signals?

I've never seen anything like that. Many oil filter adapters are easily drilled and tapped for a sensor though.

And Hyundai uses all 1/8-28 BSTP thread. Many try and use the NPT 1/8-27 thread. You can do it but.....
