Germany did not lose the Battle of Britain

hope no one thinks that all the parts in those exchange easily.

That kind of fit was possible in 1936 too. The tightness of machining then for those engines was high though nowhere as CNC fast as now. But they did have to make the things able to cold start, be fixed relatively quickly, and last just a bit longer.

Perhaps you need to have cut metal yourself to understand just how fine the better AC engines of those times really are. Calling the Merlins crude is like saying that people in the past were stupid because they didn't know what is known by some people now. Yet we can't get a real dialog on global warming....

You want crude, get an old Harley made to 1910 technology -- any made up to perhaps the 60's.

You can't know much about engines if you don't realize that any piston engine from the 1940's were crude. F1? Get a grip dude, taking an extreme approach like that and comparing those engines to Merlins just makes you look narrow. One race? Read the F1 regulations for 2011, and also compare how many revolutions those engines makes between tear downs to a Merlin from 1940. We're talkin roughly 19000rpm compared to 2500rpm. I wouldn't be surprised if F1 engines surpass Merlins in terms of longevity through crank revolutions. But put simply, they are not comparable.

I'm not calling the Merlins crude because people back then were stupid, you would probably think like that but I'm saying that Merlins(And DB600 series for that matter) are crude because it was on a lower step on the evolutionary scale. Yes, we still use internal combustion engines and yes it is (mostly) the same principles but when a 3L straight six from BMW can fork out over 300hp/400nm reliable power you gotta wake up and smell the coffee man. There's a reason to why piston engines left fighter aircrafts. They were crude, too much prone to failures and something better came around.

Want a fair comparison? Take a 1940's car engine and compare it to a modern one. Any engine.
