V8's

[Guest RB26DETT]

Hey guys. Kinda bored right now. This has questioned me for a long time.

 

I've always wanted to know why American V8 engines have that same rumble noise. I thought that because maybe the it has 8 cylinders V mounted but the Italians have V8's too but don't have that rumble you get from American V8's. Italian V8's have that high pitch sound.

 

Enlighten me. :D

in short American V8s are normally a bigger litre-age (cc) and don't rev to the same rpm as an italian V8 - higher rpm higher noise

 

in detail though engine noise is effected by:

 

bore and stroke (which combined determines capacity cc/litre/c in)

rev limit (which will be effected by the bore and stroke)

cylinder firing order - and in turn which cylinders feed which exhaust if you have more than one exhaust pipe

exhaust - length of pipes, number of muffler boxes (and their size) pipe diameter, where/how the exhaust is mounted to the car and if they add any clever baffles to 'tune' the noise

 

well that's just a few of the variables ... sorry can't think of much else ... I don't design engines!

Whatever it is, I think American V8s sound better than Italian V8s
