Max EGT? Options

[technicalninja]

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!

There is a lot more that could be discussed about running airplane motors and lots of old wives tale lore out there, some of which is dangerous.

Not the right forum for that beat up discussion

I am a disciple of Deakins whose much researched and proven by experiment knowledge is documented in his Avweb publications found here

All aviation oriented but universally true for anyone who wants to understand better what goes on in a combustion chamber whether it is aircraft or automotive, and very transferable to our air cooled motors

Water cooling can tolerate and cover a bigger range of operating errors. It can also provide a more stable environment for optimum tuning, thus the disappearance of our “novel” addiction

I really need to get my EFI project going (again). Too many diversions!!

Thanks to everyone for the advice!

That page linked above is a KILLER resource!
I just "blast read" a couple of the articles...
Added that link to my favorites bar!

@ChrisFoley , thanks for the detailed response!
Your data was very helpful!

@gereed75 I'd love to discuss what you have in mind regarding you EFI project.
This thread isn't the place...
Do you have a build thread that I could look to?

I'm planning wild with a MS3 Pro. These ECUs can log SO many parameters it's like having a dyno built into the car.
