Also interesting LACK of flame on this merlin, packard I presume, fuel types on both vids...who knows.

this is perfect example of a badly maintained RR (the former, whose owner/operator should be slapped in the face...repeatedly..with a big spanner...) and an engine who's heavily modified (that's Strega from the Reno Races) and maintained to perfection.

Yes, sure, but keep in mind this a Meteor tank engine, derivated from a, but not a Merlin! So it is easy to imagine it was not that well maintained for a track vehicle use, that it may have had a much harsher life than an aero engine, and also the sparking system is different etc etc...
Besides it is running on a bench just for fun, driven by UK amateurs which are not swimming in money like the Strega people...

So please, a bit of moderation would not be out of place...

One can clearly see that No.5 Cylinder on the left side and first No. 2, 3 and 4 then only No. 3 Cylinder on the right side have a different exhaust flame (red-orange vs blue-white).
Later the different exhaust temperatures are clearly seen.

That Seafire vid has a single yellow burst from each cylinder then it all went blue. I think there's evidence enough on here for Oleg to get it right.

Just to be accurate I'd stay away from any race aeroplanes. God knows what they're using in those things to make them haul *ss like that..nitros, alcohol. They're forever blowing engines in those races.

Well yes, the thing is not the same, pistons were casted instead of milled, components were made of heavier alloys etc.. but the engine would still run fine.
If you love engines you don't run them "just for fun", because one day they'll get rare and then who's gonna have fun? The engine is obviously not well carbureted, besides giving it a sudden revving just to have some flames spurting out is just plain stupid.. that engine could be used in a tank restoration, and not as some "fun toy".

Sorry if my opinion is offending you mate, but hey guess what, we live in a free world...

yep, nitrogen, ethanol, water injection.. you name it!
