A somewhat surprising conclusion if I may say so. The sandwich plate is not a sensor housing and its dimensions are controlled by the need to mount the oil filter and have appropriate pressure tappings on the side. That you wish to mount a combination sensor on it may well be difficult or even impossible given spacial considerations but it is what it is. If such is just not physically possible you can consider fitting a separate oil pressure sender that could be mounted remotely [if needs be] and then fit a temperature sender using the sump drain plug tapping as the mount. A combination unit may well be more desirable but just not practical given the spacial geometry available.

Either way good luck with the search. Just finding a sandwich plate that fits the 928 geometry is difficult enough- do let us know what you manage to come up with as it is quite an interesting challenge.

Sterling, I think KillaV is using one on his turbo mount car. He should be back in town now after the holiday.

Sterling --

The temp you want to monitor will likely be the return oil flow from the cooler(s). The oil filter sees full-temp oil from the sump in and out, so would probably not be my first choice. If you want to look at sump temp, drill and tap a hole where the 16V oil separator drain used to connect, and put a long temp probe there.

My two cents...

Agreed, you want to measure oil temps in the pan.

Another idea, see this thread:

I have one similar to this in my Murf928 Supercharged 928 (since the link in the above thread is dead):

As noted in that thread, Lindsey Racing sells one:

They also sell a pressure adapter:

I thought the oil flowed from the pump to the cooler (via the thermostat) and then to the filter then bearings. So the temp at the filter would be cooled oil on its way to the bearings. Is that not correct?

Jim --

For some reason I think the oil flows from pickup to pump to filter, then the thermostat bypasses some of the oil around the coolers until the oil warms, at which point all oil flows through the coolers. I guess I need to review the oil flow map in the WSM before I share more disinformation.

Knowing sump temp is interesting, but the temp and pressure of the oil going to the bearings is what I would probably consider essential. Sump temp only gets critical if it gets extreme to the point of degradation. Hence the idea of looking at both.

I dont think you want to install a sandwich plate for this application. You need an M18-1.5 inline sensor adapter. As mentioned above, Lindsey sells one. I believe Greddy also has a similar adapter. I have not run across an inline m18-1.5 sensor adapter with a M10-1.0 as required by the Bosch Motorsport sensor, but there are common M10-1.0 to 1/8NPT adapters.

Same sensor with the 1/8NPT adapter works well in aftermarket fuel pressure regulators for accurate fuel modeling with standalone fuel management.
