Hi

Im setting up my telemetry on my plane . I have an O.S. 46 ax . My question is what is how hot should the engine get or what is the nax temperature.
Any replies will be greatly appreciated.

I wouldn't be too concerned with engine temp. The engine is going to run at the temp its going to run at when set properly. On my car engines I like to keep it under 300°F though. Airplane engines have a built-in cooling fan. As long as the needles are set right, there's nothing to worry about.

As long as you set your high speed needle 300-400rpm rich of peak, you're golden.

engine temp varies a lot from around 200 degrees F to about 300 degrees F. What you need to do is log your engine's temperatures for a while and see what you are getting for numbers. Then if something out of the ordinary happens that would be of concern then.

Hi!
Forget about any engine temperatures!
Set your engine a little rich and it will run just fine! That's how you set an engine! Not by temperature!!!!!

What about cowled in engines

As long as your cooling air intake and hot air exhaust is proportionate and of the proper size, it should be a non-issue.
