We have hundreds of Merlin/Packard V12's floating around here at work. You could say my boss is more than a fanatic.. It is amazing when we fire one up after a rebuild. Even more amazing when the boss does a fly by in one of his P51 Mustangs how loud these things are.
You want to hear loud ...The F 22 Raptor is bad.. They did a fly by side by with a Raptor and a P 51 at the Ocean Md air in June, the P 51 looked like a matchbox plane compared to the Raptor. The sound of the P51 s supercharger is awesome.
