Firing order has to do with a lot of this. A lot of American muscle V8s are set up on a flat faced crankshaft, meaning that often times they’re set up so that when the left bank cylinder fires, the right bank cylinder fires after. This opposition is what makes that rhythmic, balanced, orderly rumble.
Why do V8 engines burble?
The short answer is the growl comes from the fact that most v8 engines use a cross-plane crankshaft. Cross planes have each connecting rod journal 90 degrees apart, this leads to the engine not firing each cylinder with equal time in between each pulse leading to the burble sound.
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 a V8 sound better than a v12?
The large pistons with the larger intake and exhaust valves sing a tune no other engine can match. BTW the larger valves and combustion chamber which is the engine heads and intake, exhaust system is bigger so engine has more air flow which also helps the sound of the V8.
Why do V6 and V8 sound different?
There are moments in the firing order that cause two exhaust pulses to be produced from the same side of the engine, thus creating an irregularity in the sequence and spacing of exhaust pulses. … Different configurations of engines differ in sound due to the values of the dominant frequency emitted from each motor.
Is a V6 louder than a V8?

What cars use fake engine noise?
This system was introduced in 2011 on VW’s Golf/GTI, and has also been used on the Jetta/GLI, and Beetle Turbo. The same technology has also been used in other cars from Volkswagen Group, including the Audi S3 and Škoda Octavia vRS.
What is the loudest V8?

It—or really its 755-hp supercharged V-8—sang a 99-decibel swan song for the engine layout Chevrolet had relied upon since 1953 for its all-American sports car.
Why are V8s so loud?
People who drive cars with v8 engines LIKE to hear the engine run, especially when they floor the gas pedal. So the manufacturer installs an air intake system and exhaust system that allows the v8 growl to come thru.
Why do 4 cylinder engines sound bad?
Four cylinder engines are less smooth than V6s and FAR less smooth than inline sixes. This causes more vibration in the car, which makes it louder.
Is V12 better than V8?
A V8 is an engine with a V-shaped cylinder block and eight cylinders. … V8 engines are smaller than V12 engines, making them a more efficient choice when space in a vehicle is limited. V8 engines also offer better fuel economy over V12 engines as they consume less gas due to having fewer cylinders than a V12.
What car has a v16 engine?
