Why do American V8s sound so good?

Each pulse makes a tone, which combined with the other pulses forms a harmonic series. The same thing happens in all engines, but it's the irregular firing sequence that gives a big V8 its distinctive throbbing sound.

Why does American V8 sound different?

The cross-plane crank has an irregular firing order, sometimes producing two exhaust pulses on the same side, as opposed to alternating. This irregular firing sequence is what causes the deep rumble of an American V8 (cross-plane) as opposed to the rhythmic, even pulse rate of a Ferrari or Lamborghini V8 (flat-plane).

What is the best sounding American V8?

Why do some V8s sound different?

American V8s have a pedal every 90 degrees; Ferrari V8s have pedals every 180 degrees; hence the term "flat". The result is a different rhythm of the firing of the cylinders, and a different rhythm to the exhaust.

Why do American V8s produce so little power?

Large displacement American V8s are typically pushrod engines, and this engine design has characteristics that make it more difficult to produce high horsepower per liter.

Sound Expert Ranks the Best V8 Engine Sounds

How high can a v8 rev?

Its peak power is still probably around the 9,200-9,400 RPM range with a drop-off as the engine spins faster, so tuning those higher revs for power will have to come later. We've seen other high-revving LS builds with redlines in the 9,200 RPM range, so this makes sense.

Why are American engines so big?

In America there isn't a tax on engine size. Whereas other countries do have taxes. The bigger the engine, the bigger the cost (of the tax). So it simply doesn't matter how big the engine is here (in America).

Why do Ferrari engines sound so good?

The Ferrari engine start sound is an expression of pure joy borne from world-class engineering, the result of decades of engineering refinement to produce a throaty rumble connecting the driver to their car. Ferrari engine sounds are unique, both on the road and on the F1 track, and that's by design.

Why are AMG sounds so good?

"The regulations were getting pretty difficult for the sound to just come from the exhaust system," said Bogenschutz. "So we added the AMG pure performance sound, there we take the real sound from the exhaust system, the pulsation of the real sound and move it inside the car.

Why are V8s so loud?

Each pulse makes a tone, which combined with the other pulses forms a harmonic series. The same thing happens in all engines, but it's the irregular firing sequence that gives a big V8 its distinctive throbbing sound.

Which V8 is the loudest?

Dodge Challenger Hellcat

With a massive 707bhp V8 engine under the hood, the car lets out a 'growl' of around 100 decibels, which is only 20 decibels short of the average noise of a rock concert (120 decibels).

Which American muscle car sounds the best?

What muscle car sounds the best?

Are American V8s cross-plane or flat plane?

For the most part, cross-plane cranks dominate, especially in American V8 engines, while flat-plane cranks typically show up in high-end Euro exotics and full-on race cars.

Does firing order change sound?

Firing order doesn't affect the sound of the engine, but it does affect the sound of mechanical anger, which can be found in old Pontiacs and Ford FE's. It's possible that it's the exhaust ports on those two.

Why do cammed cars sound different?

The main reason that cammed trucks are louder is that there's more fuel going into the engine, meaning a louder idle and more volume at any given speed. While this is mostly true, the extra noise doesn't just come from increased fuel intake.

Is C63 loud?

This Mercedes C63 AMG is fitted with an obnoxiously loud iPE exhaust that some people will love or loathe!

Does AMG performance exhaust add horsepower?

How Much Power Can it Add? Actually, the exhaust flaps have more to do with sound than actual performance. If you are driving an AMG SL65, you might notice more of a power gain than if you are driving a CLA45, but in reality, it is only a few horsepower.

What sounds better V8 or V12?

The cylinders in a V8 engine have more diameter individual than in the V10 and V12 engines. It therefore means that more fuel is available for displacement in a V8 engine, giving it a richer and better sound than that of V10 and V12.

Are Nascar engines flat-plane?

The engines in Nascar Sprint Cup cars are 90-degree pushrod V8s, just like those that have powered many vehicles on American roads for more than 50 years. But today, the engine under Jimmie Johnson's hood is a custom-made 850-hp 358-cubic-inch thoroughbred that's optimized to run flat-out for no more than 1000 miles.

Why are European engines so small?

As Reuters explains, automakers have steadily been downsizing the engines in their European-market offerings in response to increasingly stringent emissions and fuel economy regulations. These tiny, often turbocharged engines perform admirably in government emissions and efficiency tests.

Why do European cars have less horsepower?

The reason for the low horsepower rating was rather simple: economics. Cars were taxed based on their engine size. One fact has to be stressed: one horsepower equals 746 watts. Actually one mechanical horsepower (also known as an Imperial horsepower) equals 550 foot-pounds per second, or 745.7 watts.

Why does Corvette still use pushrods?

Pushrod engines are also simple, with far fewer moving parts that could break over time. That's a big part of the reason why Chevy's small-block V8s are famous for their reliability and durability. This simplicity also means a pushrod engine is generally cheaper to produce than an equivalent overhead-cam unit.
