NA vs Turbo sound...
Discussion
I suspect the difference is actually minimal. Despite what many motoring hacks may have claimed in the past with turbo's robbing the exhaust sound.
Yes a turbo interfers with the exhaust. But so does a silencer/muffler. If you are comparing a straight through exhaust with a turbo, then the turbo will likely be slightly quieter and maybe a slightly different sound. But you can alter the sound of a na by different silencers anyhow.
Just YouTube turbo Corvettes, Camaro's, Trans Am,a or Mustangs and compare to the same vehicles running n/a. Obviously you won't have the turbo noises on n/a, but the engines and exhausts won't sound a busting lot different in my opinion.

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.

Comparing a 4 pot, 5 pot and a V8. Is unlikely to help the op when asking what affect the turbo has on noise/sound Then you tube A launching from a Rally Stage of a say Lancia S4 evolution or a Audi ur Quattro S4 etc.

te for a V8 turbo. After the e39 and the v10 it might be a lot more powerful but it just sounds strangled and muted.ging84 said:
You can't really have a situation where the only difference is the turbo, the turbo is integrated into the exhaust manifold, and the intake, 2 things which both have a very big influence on the sound of the vehicle.
Obviously in terms of air flow, then yes a turbo will affect both exhaust and intake. But you don't have to mount the turbo at the exhaust manifold. You can remote mount them. And likewise with the intake, you only need to plumb it to the intake manifold. Most n/a manifolds are perfectly up to the task. BigLion said:
If both engines were 4.0 v8's and the only difference being one was a turbo, would they sound similar still?
I would say yes, I had a M3 with a N/A 4.0 V8 and it didn't sound very good, I also heard a RS6 overtake me with a 4.0 V8 twin turbo and it sounded equally as bad. I blame the emission laws.
At a PH meet a few years back, there was an RS6 and an R8, the RS6 was the turbo'd version of the same engine as in the R8 and the latter sounded noticeably better, but I would imagine the R8 was designed from the outset to give a better noise in the first place. My understanding was that a Turbo normally silenced an engine somewhat, all things being equal.

Personally I love turbos
I've experimented with this a bit. In my experience, the turbo kills much of the high frequency noise from the motor - to be replaced by turbo whine.
I find the "angry" noise of an NA V8 is lost on a turbo, even if running straight through.
"Best" on both motors was the same, but the NA still sounded better. Until the turbo comes on boost and I stop caring about the exhaust noise.
