diffrant engine sounds Options

[flmont]

What gives a engine its particular sound,meaning a..type 4 sound compared to lets say a MGB,...or a flat six to a inline 6,as in a triumph TR6...a Ferrari V8,.sound so much diffrant than a American V8,..is it Alum.vs Iron,..overhead cam belt driven vs chain driven,I know exhaust and cams.will make a diffrance to a point,..Carbs vs fuel injected,...valve size's,..??? Just curious on how that engine noise / music is created,..Thanks Frank

That sound is even better in a 914!

Especially in an 81mm, with titanium retainers, twin plug, and 906 cams

Number of cylinders and firing order, and obviously exhaust, are the biggest factors in what an engine sounds like. Certainly this is why a 4 sounds different than a 6, 8, 10, 12, etc. Some 8 cylinder engines sound different than other 8's due largely to firing order ( I assume this is one reason a Ferrari 8 sounds so different from an American V8). Other factors like size, camshaft aggressiveness, type of intake, different exhaust configurations, etc. all factor in as well.

I used to wonder why Harleys sound so unique, until someone explained to me years ago how their engines are configured. It's a V twin of course, but the two connecting rods are on the same crankshaft jounal, which makes for an odd fire 2 cylinder and a unique exhaust note.
