I am into vintage planes as well as cars. Everybody always talks about how awesome P-51s sound and they are right, but listen to this BF109G. It has it's original supercharged Daimler-Benz DB605 engine. It has a nice choppy idle and just listen to that supercharger on the medium speed passes. Awesome sounding machine.
