F1 Engines.....

[Technonotice]

Why do formula 1 engine's lack the familiar warble/sound you get on a road going V8?

I realise the rev limit is a lot higher and they have straight through exhausts.

But are there any fundamental differences between the engines causing the different noise?

Apologies for the simple question.

Cheers!

welcome to flat-plain crank V8's....

they sound like a screaming 4 pot X2 rather than a classic V8 Burble.

Isn't the noise also because they have a large bore but short stroke, they buzz rather than rev. That's why they can rev to 17,000rpm (or 20,000 in 2006)

Flat Plane crank and the exhaust is so short that the sound doesn't get a chance to set up a resonance down the length of a pipe.

Several things cause the difference in sound between road V8's and F1 varieties,the first is obviously revs which alters the frequency of the exhaust note,another is the way the header pipes are linked,this is really why flat-plane cranks are used,because it enables the header pipes of each bank to be connected easier (in order to achieve more efficient exhaust scavenging ),but avoiding pipes crossing over from one bank to the other.Assuming the firing order of the FP V8 is even,the sound of a similarly plumbed 90 degree cranked V8 should be identical,it is the way the headers are linked,not the orientation of the crankpins which causes the different notes .The separate intake trumpets of the F1 engine will also give a differing sound from a road V8 which generally has intakes feeding from a plenum or combined manifolds.Incidentally ,a good proportion of the overall noise "signature" from F1 engines is from the intakes,but you can't hear it for the exhaust!,it adds to the overall characteristic wailing sound .
