^ Quite possibly one of the best sounding V6 engines made.

Back in that era...really up until the 1960s...torque was king. These big Duesenbergs, Packards, Cadillacs, etc. were heavy cars and getting them up & moving was a demanding task. In 1930, a 452 c.i. V-16 Cadillac generated only 165 HP but put out 318 ft/lb of torque at only 1400 RPM. In a big heavy road car, low-end grunt was much more useful than high-RPM sizzle, so they were able to get away with rather small carburetors. Also, the majority of roads weren't all that great, low octane fuel was the norm, and high-speed motoring wasn't as desirable as it is today. For luxury car owners back then, smooth and quiet was the way to go.

That’s showing the “turbo-supercharger” - it’s immense size and all its ducting - from a P47

MRG?

Hooked to something like these?

From RRVI: The Singer/Williams 4 cam engine - designed (I think) with Metzger's help
(Sure wish I could have heard it run!)





A rather exact reproduction of the original Metzger 4 cam, built in Germany by a friend of Metzger's, with Metzger's guidance, and using original plans. They claimed there were only two ever built, that the builder of this one knows where one is, and not even the Porsche factory has one. Of course, I am just going on what I was told at RR.
