I like the two-handed tach! That’s a typical aviation tach used with most all old reciprocating / piston aviation engines.

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.

Merlins were also used in civilian aircraft. Canadair Northstar was a DC4 with Merlins instead of radials. The last surviving one is in Ottawa Ontario at the the Canada Aviation and Space Museum. I delivered an ornithopter to them some years ago and got the back room tour of the place. I can say I helped with the restoration of this aircraft. I held one of the magnetos up while the tech removed the bolts to get it off the engine. Lol. https://en.m.wikipedia.org/wiki/Canadair_North_StarKevin

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.

I have attended all sorts of shows and love everything from Steerman's to them to B bombers. Awesome sounds!

Only reason I can think of for the paired rear exhausts is heat & flame too close to the airframe. They do spit fire at times. Didn't that aircraft have a lot of wood in its construction ? (Something like that was called "the flying piano" for its wood content.)
Love the sound of a Merlin or Griffon flyover at speed. Nothing else like it. Wonder what they'd sound like with an exhaust more like the old V12 Ferraris...?
As for the RPM, I would think the props are part of the equation. And back in those days engines weren't apparently spun at high RPM in most applications. Correct prop blade tip speed is critical. Can’t remember the exact speed ( think it’s around 320 mph) but I do know once you exceed it the blades tips will stall. As the speed / rpm is increased the stall works its way up the blade toward the hub. Same as spinning the tires for us car guys.
