I already know why in general, but a similar detailed breakdown of the sound differences between inline 6 and V6 would be fun. The RB, the JZ, the Australian Barra, all iconic sounding motors to enthusiasts.

A breakdown of the difference between the raw sounding RB and clinical JZ would be cool too. Though owning an RB I think the rawness came from the terrible factory timing optical encoders, since upgrading that to more accurate kit it sounds much closer to a JZ.

For context, here's what it sounds like: https://youtu.be/MCCYMys6aDw?t=890 (14:50 in case the time link doesn't work.) And from the video embedded at the end of the article: https://youtu.be/zUU0aW3yyMc?t=32 (32 seconds in.) Meanwhile, here's the Ford GT40: https://youtu.be/KJJ0nIbn_Ts?t=120 This is a replica GT40 with a modern Ford 5.0 Coyote V8: https://youtu.be/6g3Ay83JLJE https://en.wikipedia.org/wiki/Ford_Modul…

I've got to add my favorites too.

I love the sound rotaries, but they are easily the most painful to the ear in regards to hearing damage. An open exhaust rotary is like a percussive area denial weapon. I had one on track with me and I lifted when we went down the straight together, as they just about blew my ears out.

It's also because the engine has a 90-degree V-angle, so the cylinders on the left bank are 90 degrees out of phase to the cylinders on the right bank. Each bank is effectively a 4-cylinder which fires once every 180 degrees, so having the two banks 90 degrees offset means the engine fires evenly every 90 degrees, producing a higher-pitched sound. In audio terms, there are no audible "1x engine rotational frequency" or even "0.5x engine rotational frequency" components. It's perceived as an octave higher than an inline-4 at the same RPM.

hi, im a professional diesel engine mechanic and can easily explain what youre hearing. Most italian/european sports cars (with the exception of Mercedes in the past 3 years because American customers) have machined their crankshafts as "flatplane" cranks. Flat-plane cranks, no matter what firing order they have, will always alternate from bank to bank. This yields optimum exhaust scavenging and thus doesn't require…

Hi, I’m a longtime student of the American culture and I think the primary reason why Americans love it so much is because it temporarily masks their tinnitus and not because it melts their cold hearts.

Approximately 10 percent of the U.S. adult population — over 25 million Americans — experience some form of tinnitus. And an even larger percentage is suffering from hearing impairments.

Broken mufflers and loud engines mask the tinnitus sounds and finally they can relax. This is also the reason why they prefer to hang their Freeways in the air, in the middle of the city. And why their cafes are unbearably loud with the sound of refrigerators competing with the loud music.

I'm not sure if this is a joke or not. I know lots of young people, myself included, who don't have tinnitus and also like V8s or V-twins motorcycles in my case.

Why do you think Americans suffer from tinnitus more than other nationalities?

Americans like it because when you sit in a big V8 and smash the accelerator it jolts you forward and pins you in the seat while the engine is roaring like a lion. It's fun, like going down a hill in a rollercoaster. That's really all there is to it. Hearing it makes you think of the fun yourself.
