Brian:

Some run a bit hotter -- the engine intake air on the SR-71 was about 500C or more at speed (test stand operation requried running a JT5 at full throtte in front of it to pre-heat the air!). The exhaust stream was incandescant, somewhere in the temperature range of a hot acetylene torch, I believe.

Engine itself was orange on the leading edges, and the exhaust section was cherry red.

No maker's plate on the side, either -- prototype engine sucked it off the rivets and "ate" it -- not very successfully as I heard. That may be the engine at Wright-Pat with the big gouge in the front compressor blades.....

Not your typical AirBus engine, though.

I'd consider 600C incredibly hot for engine parts!
