Oil temp sensor location

[couchboy]

Hi guys

I'm in the process of buying the sensors for my rb25det track car and I'm looking at get the Bosch motorsport pressure and temperature sensor 0261230340 which I'll be mounting to my thormostatic Sandwich plate is the location of the oil temp sensor ok to use or is there a better place to mount it to get a true reading?

Any recommendations would be greatly appreciated.

Cheers

Those sensors are a great idea to simplify plumbing and wire routing, hope they are reliable over time.

Any thermostat with a properly designed sender port should be fine to use; you obviously can't take either temp or pressure from the oil cooler loop in a system with a thermostat. There is some disagreement about whether you want pre or post oil cooler temperature, my view is I want pre cooler temp because I want to know the hottest the oil got.

Hi Duncan

The Sandwich plate is a mishimoto one which my tuner supplied/recommend so that what I've got and the port is in the side of the plate so should be ok to use.

This is combo P & T right?

So the actual most important use of that sensor is P, with T being not quite as vital to know.

The place to measure P is at the supply side to the engine. You want to know what pressure the bearings are seeing.

Hi gtsboy

Yea that right.

What really matters for oil temps is what the temp is for the oil the engine gets. Which for a wet sump system requires a sensor which measures sump oil temp.
