4 of these flew low over my head and when they passed by it literally gave me a chubby.

As far as planes go, those things are badass!

I'll see your P-51 and raise it with the supreme sound of a Supermarine Spitfire

Supermarine Spitfire AWESOME SOUND !!!
..had the pleasure of seeing.. and hearing this awesome sound for myself, standing in a friend's back yard on the edge of RAF Conningsby, Lincolnshire UK...

My experience was also in person and saw four (almost side by side)  P-51's go low on an overhead pass and as they passed over and I was behind their exhaust, the hair stood up on my neck (not kidding).
I'm not sure you can call the Supermarine Spitfire a "supreme sound" compared to a P-51. At one point they both had Rolls-Royce Merlin engines.
Although if it had been 4 Spitfires going over my head, I would probably agree with you. Youtube video sound cannot compare to hearing it in person.

@ Monsterlover- that commercial is good!

don't they have the same or similar motors?

Ducatamount says the P-51s also ran RR Merlin engines 

I didnt know that.

I just have a Spitfire fetish

Holy crap that Motus motor sounds good!

I have heard and seen many engine configurations and designs over the years( in person, video, etc)....still to this day...none compares for me to being on the wall at the 60 foot mark when a top fuel dragster goes by on a sub 4 second pass....

Benelli 900 Sei. I'm always searching the classifieds for one because of this video.

not that far off from the sound of a CBX with the right exhaust system....and those are more readily findable I think....

P-51A originally came with an Allison V12.

Brits put a Merlin in it.  Fixed it.

North American Aviation took it back, fixed the British hack job on the cowling, and the P-51B was born.  All the common war-era B, C, and D models were Rolls Royce or Packard Merlins (Packard produced them under license).  One of the greatest engines of all time...

But, for either the Spit or the Mustang, one of the most epic engines fitted would have to be the almighty Rolls-Royce Griffon.

Toward the end of the war, the Merlin was belting out ~1600HP.

The Griffon?  Over 2400 HP.  

They were used on certain variants of the Spitfire.  Also used, at least experimentally, on late-model P-51s.  They were highly desirable as racing engines after the war.  One of the more famous users was Steve Hinton.  Anyone remember the P-51 "Red Baron"?  I had the pleasure of meeting Mr. Hinton at the Planes of Fame museum in Chino, CA, when his crew was restoring a Mk XIX Spitfire, running a Griffon with counter-rotating propellers.  That day was the second time they'd fired it up.  When Dad and I met Steve, he told us if we had time, they'd be pulling the Spit out of the hangar for test runs.  We looked at each other and grinned.  That. Was. Epic.

Here it is, a few years later, all buttoned up and ready to fly:

The real music starts around 3:00:
Spitfire MK19 (long best of)

Getting back to pure sounds... while the Merlin is excellent and the Griffon is awe-inspiring, I do appreciate the music of the Allison V1710.

Anyway... I love too many engine noises to pick a favorite or dig up examples of each.  Here's a woefully incomplete list:

Eagle Speedster (Jag inline 6)
Jag E-type 3rd gen V12
Every old Ferrari V12 ever made
Dino 246
Lamborghini Miura
Lamborghini Urraco (2.5L V8)
Cadillac V16 (the original)
Allison V1710
Rolls-Royce/Packard Merlin
Rolls-Royce Griffon
Too many Porsche flat-6s to list...
60's Lotus/Ford race cars
Pretty much every pre-Chrysler Maserati (pre-1980?)
Too many vintage Alfas to count...
60's Chevy V8s
Shelby/AC Cobra (289, 427... doesn't really matter, they all sound great)
Almost anything breathing through Weber IDFs, IDAs, or DCO-series carburetors
Old European straight 4's and 6's with Dellortos and/or Stromburgs
Almost any race car made before ~1975
Ducati 916 (notably the 916 SPS... which was the 996cc race motor)
Ducati Pantah air-cooled 2-valvers
More MV Agusta variants than I can recall
Triumph triples
Original Nortons
Motus V4
And yes, even the occasional well-tuned Harley-Davidson

The most important takeway is: there are MANY cool-sounding engines.  I've heard generic Ford 4-bangers (think Duratec) stuffed into Lotus 7 replicas with nice intakes and exhaust systems, and they sound so dramatically different than the car they came out of (usually a Focus) it's astonishing.

Anyway... looking forward to more cool finds in this thread.  I am always down for hearing great engine noises.
