If you are going to install a turbo temp gauge, to accurately read the turbo temp the gauge must be mounted between the exhaust manifold and the turbo. If you mount the gauge after the turbo then you are reading the turbo exhaust temp, which will be about 200-300 degrees F or more, cooler than the turbo because the exhaust gasses have already lost energy and cooled in temp due to the "work" done by the gases to spin the turbo. So if your temp gauge is already mounted at the turbo's exit, just realize the max temp you want to see on the turbo temp gauge is about 900-1000 degrees F. Add in a 300 degree rise in temp over the turbo to the manifold and you have the "magic" 1200 degree F limit you want to never exceed on your turbo temperature.

 

Where would a fella pick up a turbo temp gauge? how much do they run do you know?have you ever heard of a guy installing a turbo oil cooler on a PSD? i know they make them for the little rice rockets and i got to thinkin why couldn't a guy fit one up to the turbo on his powerstroke, but i dont want to be that guy

 

I think he's using "turbo temp guage" interchangably with EGT guage....

 

The oil in your turbo bearings is the same oil that's in the sump for the engine. The ones the ricers run is because the turbo is an add-on. The fact that the engine oil also lubes the turbo is one of the reasons you let the truck cool down at idle.
