YouTube AC Cobra 427 sound doesn't get much better from a NA big block v8
Then you tube A launching from a Rally Stage of a say Lancia S4 evolution or a Audi ur Quattro S4 etc.
They all sound good to me but I'd take the Cobra every single time - even assuming the values are all equal.
You can keep your 'big block' V8's.Then you tube A launching from a Rally Stage of a say Lancia S4 evolution or a Audi ur Quattro S4 etc.

German M3 V8, like ripping paper (I think the yanks call it) - now that's what I call a V8.
My S2000, brilliant N/A, the crispness.
Nissan Skyline GT-R, sounds absolutely incredible turbo charged.
Do you like the Group C racing cars? Or Can Am racing cars? Or the V8 Oz racing series or NASCAR? If yes you do like big block

As others have said, the best way to hear the difference is to sample an NA 911 and a Turbo. One sounds epic; the other is meh.
Well a 1.6ltr wheezy Maestro engine isn't great, whereas a 911 Turbo sounds epic in comparison. None the less on the race track a lovely Caterham 600R where you push it so hard you get into valance bounce zone is truely stunning but a Derv Etron Audi would Slaughter it in every way.

As much as it pains me to say it the M5 sounds a bit ste for a V8 turbo. After the e39 and the v10 it might be a lot more powerful but it just sounds strangled and muted.
that's just modern BMW's, they make them sound crap and add fake sound via the speakers, Audi and Merc's blown V8's both sound most excellentWelshbeef said:

Exhaust noise is overrated and often contrived (See F-type/C63 as prime flatulent examples) induction is where it's at, M used to be masters of it the S54 and the S65/S85 sounding incredible at high RPM, the new turbo Ms not so much!
Disagree with that sorry. A lovely burbling V8 then blipping the throttle is great.
Induction is good but exhaust superior - excl dustbin exhaust added to 1ltr Nova's.
Not been in a turbo'd E46 but I have experienced a supercharged CSL and, whilst extremely rapid, the loss of its signature induction noise was a big loss for me anyway

Or at the cheaper end of the spectrum, an E90 330i vs 335i. I do understand your point though.

I've never particularly liked the noise made by cross-plane V8s. I don't like unequal length header boxer-fours either which is probably related because they have a similarly "off-beat" sort of element to their exhausts.
From inside the car, a good TVR Cerbera V8 is intoxicating as it comes on song.Edited by kambites on Thursday 8th December 09:58
When the Tuscan Challenge switched from RV8 to AJP V8, it did lose a little drama - especially the gut shaking first corner, with 30 odd cars on full chat - but I grew to love their howl, which, flat-out, sounded like two Lotus Cortina engines working in tandem. Which is no bad thing.
As for Pork, I've found the in-car difference between N/A and turbo is less pronounced that the exhaust note when heard from outside the car, barring the obvious caveat that a GT3 is able to rev higher, of course.

I think that's why I loved my Cerbera so much, because whether the windows were up or down you could still hear the engine and exhaust noise.

However, the induction noise on the CSL was on another level for me (very limited exposure to TVRs though!), and I just never felt the need myself to swap out the exhaust, as I felt any I've experienced actually detracted slightly from the overall noise and got in the way of the induction. All personal preference of course
In saying all that, my current bi-turbo'd V6 in the old RS4 sounds far more muted than all of the NA 6-cyls I've had, but I love the subtlety of it so it will be staying standard for the foreseeable

I'll agree with the slightly muted exhaust noise on the E92, but then I've always thought most M-cars can benefit from a cheeky exhaust swap. Loved the Eisenmann Sport on my old 3.8 M5, and the odd pop, bang and flame from it were very naughty for what was an exec saloon barge

Agree that a M car can be modified to sound nice exhaust wise for sure. However, the induction noise on the CSL was on another level for me (very limited exposure to TVRs though!),
You can tell BMW work hard at the induction side of their engines, with a TVR(AJP8) the induction is mostly a mechanical clatter and it's quite difficult to pick the induction part out.

In a pre-cat 4.3 BV Griffith, you could wear ear plugs and still be able to feel the noise. kambites said:

Why is the engine and exhaust noise so different on turbos - intuitively you would think there is more air and fuel in the combustion chamber so everything should sound like a NA but on steroids?
Because there's a damned great turbine sitting in the way of the exhaust gas. With a naturally aspirated engine you get very clear, staccato, exhaust pulses at the tail-pipe each time a cylinder fires; with a turbocharged engine, the build up of back-pressure behind the turbine means the individual pulses from each cylinder are slurred together into a more continuous drone.

The Hayward and Scott exhaust on my M5 sounded biblical but not long after I bought the car I heard the engine with the plenum off, holy mother of fk that was something else.
