I know it has something to do with the fact that they are "flat plane crank" V8's, however I don't understand it fully and as I am now finished school with nothing at all to do I would like to learn. does anyone know of a good site that explains this well.

nobody knows

that's the Ferrari magic

Small displacement high revving..

Also , they spend time tuning the intake, then way the air goes in creates ,in part; the magic.

u can download some video................ i had 2 that is about 360............ then u can heard the sound of the great ferrari engine

The Lotus Esprit V8 had a flat plane crank too but it doesn't sound as good as Ferraris V8 more like a 4 cylinders, it's a technic used in competition.

Well, I think they pay very close attention to the length and shape of the intake and exhaust manifolds; and the number of values (5 per cylinder) has some effect. In addition, the high rpms of the engines has a lot to do with it.

Also, it's Italian.

the 5 valves is a big part of it. it's 3 intake, and 2 exhaust, with the exhaust valves having VVT which gives improved performance at high revs, hence the enormous beautiful sound

I wouldnt say that Ferrari's have small engines.

the flat crank V8 produces exhaust pulses that sound like that.
of kos not having a turbo (like lotus) and having an engine that revs high with suitable cam and intake design contributes to the music

SFDMALEX · 12-25-2003, 09:39 PM

Whats up with all the V8 talk? How will you explain the magic of ferrari V12's?

takata · 12-25-2003, 09:50 PM

we are talking abt the sound V8 makes ... no one comes close
the V12 .. ? nothing special compared to the rest

frodefe · 12-30-2003, 01:01 PM

it's primarily the muffler

There is much magic in intake/exhaust tuning. If you recall during the original Miata development, thousands of hours were spend analyzing/tuning the exhaust to make it sound *just right*...it has that slightly "braaaap" sound when cold, and then warms up to a mellow but unobtrusive growl.

But I agree with RC45--small displacement, high-rev engines (esp V-8s) have a unique sound.

Just throwing in my €0,02, I think the flatplane configuration contributes very much to the sound difference from usual crossplane garden V8.
Flatplane means you can actually rev them higher since there are no counter-balance weights involved, and in terms of engine sound you always got 2 cylinders getting sparked up at the same time (as opposed to the crossplane). Then of course the intake and muffler resonances get tuned to musical sounding frequencies I suppose. I know a link where they analyse an older Ferrari V8 and come to the conclusion that everything is very harmonic, but I suppose you need to have a lot of sound analysing experience (which I don't) to be convinced of that by only reading through it. Here's the link anyway:
