A good read on the merlin. "not much of an engineer" Stanley hooker.
Until around 42ca merlin cud not out dive a 109. And carb design of merlin would actually cut out. A mod, orifice, then diaphragm design fitted to float Chambers resolved this. Not an issue for 109vas fuel injected. Well known fact to 109 pilots to evade spit was to roll/dive, where a spit doing so wud put itself in a bad place in the sky, some 109 guys got a bit of a shock in 42

Ah. Miss Shilling’s Orifice.

Anyway, related topic, but probably less popular...

Why are motorcycles allowed to create all that awful noise, but cars are not? Surely the technology exists to silence a motorcycle exhaust better now!

I find motorcycles whizzing past annoying enough as it is, but why do they have to make so much noise?!

Lack of police resources, traffic departments have been decimated. But I have read that they are trailing noise sensors at the side of the road fitted with ANPR cameras.
I have owned motorcycles continuously for the last 25 years, & always ridden with the standard exhaust.
