Normal operating temps for p38s.

I checked the temperature difference and have noticed that the watchdog is almost always running 5 degrees cooler than the nanocom temperature.

So HammerH would see his coolant running around 91 degrees I imagine.

My Thor info is different,, engine is considered hot after 55-60 deg,, the only reason for a design hotter than 88 is cleaner combustion, but the engine build is so lousy it just wont last at 96---

LR V8's have run far more successfully for many years at much lower operating temps than Thors.

i recall reading somewhere that the LR v8's of the 60's ran about the 60degree mark
