The title is the question.
I know what to look for with water-cooled stuff. I have no experience with air-cooled stuff yet... What say you? Is there a normal range? A never exceed number? Anyone ever use 4 thermocouples? Was there any noticeable difference (#3 is of concern to me)? Thoughts, tips, any data would be greatly appreciated! |

Cool comparison - 1350-1375 is where I run my Lycoming for best power. That is about 75-100F below peak. FYI, at sea level I flow about 18 gph to make 180 hp.
That holds amazing similar to my 200 hp outboard. Ain’t physics/thermodynamics/combustion efficiency a cool thing! |

I use to do phone support for aircraft engines and once you got to 1450-1500 bad stuff was likely to happen . Turbocharged applications ran hotter but NA application your right on. |
