I have a question. Why do 6 cylinder engines have a "roar"

well my friend, the answer is very simple, you see the V8 it......SLAP ASS!

>"roar" exhaust note
>exhaust sound under acceleration

>"burble" exhaust note
>exhaust sound at idle

Are you asking for the difference between engine sounds at idle or under acceleration? You can just google why older V8s sound different man

>Are you asking for the difference between engine sounds at idle or under acceleration?
No, they both produce very distinct and different sounds under acceleration.

>>16363917
So are you asking for the difference in sound at idle?

Firing order.

>>16363919
no, the difference of sound under acceleration.

There's two parts (excuse my lack of knowledge cause I'm an amateur) - http://www.onallcylinders.com/2015/01/15/cross-plane-vs-flat-plane-crankshafts/

Firing order and whether it's a 90 degree (crossplane) or flat-plane (180 degree) crank. Crossplane cranks are the ones that pretty much every old-design non-Euro American motor uses and it causes an uneven firing order and smooths out vibration under load. There is a number of different factors which affect noise under acceleration and I think it would best be left to an exhaust guy to spell it out because it's a ton of mumbo-jumbo and I don't think anyone needs to hear it

Every circle of an American V8 due to camshaft spacing and timing will have about two cylinders fire at once at times due to the cycle of the piston in the block to number of total cylinders. The gurgle or that one 1&2 sound at idle to around is when two cylinders of the block but each side of the V8 has it's own exhaust headers flowing out the pipe nearly the same time. The V6 or mostly I6 of the era don't have that quirk, so they don't make that sound. The European alternative was make the camshaft spacing tighter when there are more cylinders so two would never fire at once for greater stability, which is to say they made V12's with the bores of 2.0 Liter four cylinders.
