We are comparing the same engine in 2 cars (992 GT3 and 4rs) with the same gear ratio and similar weigh and almost identical Dyno charts
Two different issues here:

a) Torque curve profile is a matter of design decisions. The 4L in the GT4/GTS 4.0 feels like it has more midrange torque. A few people here concur (a few reviewers, too). Most do not, including, I note, people who are not owners. You need to live with a car to know its character. Paper specs and short test drives won't tell you much. I have spoken to quite a few owners in person. Not a single one disagrees that midrange torque is somewhat wanting. Note: and we all still love our cars.

b) I don't have a problem with Porsche's decision to move peak power to ~8200 rpm per se. This exchange was initially about whether the in-cabin sound level is too loud or not. I am saying in addition to loud there is a visceral disconnect between the loud and distinctly non-linear "crescendo" of engine sounds and the resolutely linear power delivery. This disconnect reinforces the lack of torque. That's my opinion. YMMV.

That matches my experience and perception, based on about 100 miles of driving the 4RS on familiar roads, and thousands of miles in the 992 GT3 and 991.2 3RS.

I believe the lack of mid range torque is a bit of a negative on the road, but certainly not a dealbreaker. The car doesn't feel slow, just not as fast as one might expect for ~500 hp in a relatively light car. On track, it doesn't really matter, since revs are generally kept high.

Ok, let's set a few guardrails here, I'm not debating whether the 4RS is strong on the mid-range or not, I'm debating if it is strong compared to a car (911 GT3) that has the same dyno chart, the same gear ratios and almost the same weight

Regarding a), you said it, “it feels like”. The GT4 and GT4 RS power and torque curves are identical up to 5k revs. On top of that, the gearing is shorter in the RS, so yes … you can feel like the GTS/GT4 has more mid-range torque when it actually does not.

my GTS 4.0 PDK feels stronger at 4k revs. But I don't drive the RS at 4k revs !! why would you ?

ALso i bet its slower lol

4RS in 4th gear 60-100kph 3.9seconds 992 gt3 is 4.2
60-100 in 5th gear so lower revs again the 992 is even slower 4.9 vs 5.5

80 - 120 kph (5) 4.6 s 5.2 s

So the 992 is slower every where what ever revs or gears.

On paper, no question the 4RS has (a tad) more torque everywhere. "On paper." Do you own both 4RS and GT4/GTS4.0? If not, you talking "on paper."

I have owned and driven enough high performance cars to know which cars have better pull in which rpm range, which rev freer etc. etc. Those who think somehow the GT3 engine is the absolute pinnacle of engines have not experienced other top engines. Not saying the GT3 engine is bad by any means. It is really good.

And you are talking on your experience and feelings that can be worse than paper ....because paper sometimes is better that random feelings with the fake authority of ownership ..

And yes I've driven a 4RS and a GT4... At no range the GT4 feels more punchy than a 4RS...at absolutely NO range

Again not debating if the GTX engine is the pinnacle in mid-range ...is a 4L with 6 cyl..it is what it is ....

Not slow when held at full throttle. But if you're cruising at 3-5k and then hit the gas, the acceleration is less than expected for many.

but its faster in any gear

Rolling acceleration than a 992 GT3 at any revs !

Glad to hear you agree the GTS 4.0 pulls stronger up to ~4.5K. Most people are in utter disbelief when I say this.

Which rpm you choose to drive in is another matter.

again people own the wrong car, change gear ! or buy a turbo ! I don;t get what people are talking about, my Golf picks up better at 2k revs than my 4RS so what.

The point is you need to wring out the 4RS to get the power. Like the E30 M3 and the Honda 2000. A bit strange for a 4L 6 cyl engine imo.

it seems on fastlaps while it feels stronger it's far slower in gear so thats that , we are all feeling bull**** it seems, the 4rs is just faster in gear than GTS or a 992 GT3, which makes sense it has smaller wheels and shorter ratio's.

it's an NA car, the powers up top thats what we expect. ! it's far from slow at 4k revs, pisses all over any 997 GT3 or even a 991.1 GT3.

it's toy car to play with it does what it does I have 5 cars, it's a toy and my 5th car ! Like AP said, for that blat out on a early morning hoon, not going to work.
