Why do V8s have that awesome 'burble' at idle?

[dug777]

You just don't get it in a 6 or 4

Awesome sound IMO

 

[MercenaryForHire]

Because they're usually 2x the size of a 4, and 1.5x the size of a 6?

- M4H

i like the word 'burble'

 

[JulesMaximus]

It's all in perception. I love the sound of a turbocharged 2.5l boxer 4.

but the 'burble' is more than 1.5x what you get in a 6

Number of cylinders, firing order, exhaust configuration...

I have decided to put a fart pipe on one bank of my V-8 and a quiet muffler on the other side.

I just LOVE the sound of a civic with a fart pipe...they sound so freekin BAD_ASS

lumpy idle's are caused by aggressive cams. it may sound cool, but chicks dig vtec.

Fixed. vtec might bring all the 12 year olds to the yard, but real women like real motors.

i also love that sound, mmmm especially when it is preceded by a flowmaster or two

Stop talking silly

You can get some burble out of a 4... check out the Video's on this site...

SRT-4 Videos

 

[vi edit]

I've heard some say it was because of the angle of the cylinders. (90 degrees vs 60 degress of many V6's)

 

[Ryan]

Nissan VQ's have a nice burble

 

[Ornery]

Even a six can sound good. It's the size of the jugs!

I like the Ford straight six better...but it still doesn't sound like a V8...

 

[Ornery]

At idle, it sounds a helluva lot better than a buzz-box engine.

6 * 1.5 = 9

You're looking for 1.33333333...

Howard is real close. Firing order on most, 1-8-4-3-6-5-7-2, it can be seen that one side is allways out of synk with the other. That is that the firing order will fire two cyls on oneside than the other side will do like wise. All V8 cranksshafts have rod journal placement at 90 degrees. Back in the olden days 1960 something, flat cranks were tried inorder to increase HP. The rod throw journals were at 180 degrees to eachother this made the motor run as if it were two 4 bangers. One bank would fire than the otherside. This made exhust pipe tuning much easyer and intake manifold runner tuning easyer. But no real power gains were realized. They just sounded extra bitchen. Like two Offenhousers racing side by side.
Flat cranks are a thing of the distant past. But with these motors no cross or balance pipe was needed as is used in all NASCAR engines today. The X-pipe is a must to balance out the uneven firing side to side.

I hope someone understands that cause I don't.........

Ferrari still uses flat crankshafts.

That's what I was going to say. I believe the V8 used by Lotus in the final Esprit was a flat-crank as well. Those suckers just SCREAM
