Yep, the RSR sounds bloody fabulous biggrin

Can't say the same about the GT4...

Interesting video from the Monza test with the GT4CS in action:

Quite a different exhaust tone to the 911 RSR that follows it...
The GT4 sounds like a detuned something or another - either that or it was (held) in the wrong gear or limited revs. Sounds more like NA on that car and sounded a bit like the last car in the clip after the RSR, looked like an RS?

Difficult to be objective though because the sound of the RSR dominates the whole clip...anything would sound flat in comparison.

If you take a GT3 Cup car and change up at 5k rpm, that's the impression I get of that GT4 engine. It has that coarse edge to it, but just doesn't rev that high.

To me that's a good thing, but, the race car doesn't have the GPF either, so again, no nearer to the truth I don't think.

Yep, the GT4 Clubsport in the clip won't have the GPF so it would have to be something in the engine spec making the sound less crisp.

You can not compare the two - it’s frankly ridiculous to try - the costs of running these two cars in racing is massively different - they are from completely different motor sport classes and produced for different purposes - it’s obvious the RSR will sound and perform much better than a GT4 - there’s probably something approaching 7 figures cost differential between the two - you pays your money (not that you could get hold of a factory RSR) and take your choice

A very unfair comparison

Some more images...

Swan/goose Neck supports for the rear wing.. like we talk about before on some of the earlier images.
This will probably be for the race car only....not the street car.

Since when were we comparing the GT4 and RSR? Or did I miss something?

Some more video footage from Monza testing...

https://youtu.be/fySDs45ECFc

Think I’m going bloody MAD.... It’s like smelling loads of perfumes for the wife: after a while they ALL start to smell the same....!! wink

Defo sounds 6 Cylinder— that’s for sure— but it still seems to me that it could be EITHER turbo or N/A....!! I think I’ve just spent wayyyy too much time listening to GT4/Spyder mule sound-clips....!! It’s confusing my ears....

Looks great with a bit of sidewall in the images above.

I wonder how the road car would perform with a wheel and tyre configuration like that.

I'm assuming that those are 18's but that the tyres are quite wide?

That's really interesting - they sound quite different, certainly less crisp and more bassy for the 2018. Both definitely NA flat sixes though.

I just don't understand why the exhaust note is so different!

wow noticeable difference between the two... so 4.0 version of the original 3.8 for the race car... same rev limit of 7800 or lower...doesn't sound as rung out as the 3.8 did....obviously much less stressed.

Would 200cc really make that much of a difference???

You missed something - just read the posts above, if they say one sounds better than the other, it’s by definition a comparison

I'd say it the same difference between the 911 GT3 3.8's (Gen1 GT3) and the 4.0's (Gen1 RS, R, Gen2 GT3 & Gen2 RS)..... obviously not at full chat.
Number of reviews say that whilst the 4.0 is the better engine technically... the 3.8 had a certainly timbre and shrill that was unique to it and the 4.0 doesn't have.

It doesn't seem to sound as bassy as the GT4CS though:

The new change in exhaust routing/style/configuration on the GT4 must be affecting the sound a lot when compared to the 981?

I can’t reconcile the statement regarding the GT cars being NA and that sound.

The 2018 clip sounds like my 718 GTS After a steroid injection.

The 2015 is an absolute screamer. And a good example of why it has so many fans.

That 2018 sounds very much in keeping with the 718 generation.

Of course that statement from Porsche management does exist so maybe that is all there is to it. But if it weren’t for that then I don’t think any of us would be entertaining the idea that the engine was still NA F6. Based on that sound at least...?

Lower bassier note, slightly muffled sound and what appears to be lower revs/short-shifting would imply a turbo engine but it's not like this GT2-based mule:

https://www.youtube.com/watch?v=hsKStob3Cwc

I'm going to say it's a NA, but one that seems to be very restricted in revs and tuned for midrange torque rather than top end scream.

Correct me but this literally opens with the sound of turbo whistle.

2018 at Monza

https://youtu.be/fySDs45ECFc

If anything the GT2 clip supports this being turbo’d even more.
