Porsche's new philosophy with the GT3 according to AP

Seriously? LOL.
Power curves are near identical to me on both hp and torque. One curve Nm/Torque. On torque curve RS is blue other is Kw/hp where RS is red. No meaningful difference. If you think your butt can feel the difference in 200 rpm you have a very sensitive rear.
In fact the "9000 rpm" red line produces nothing but diminishing returns based on the power curve. In fact, it appears from the power curve the RS actually is generating more torque from 6000 to 8000 rpm while the .2 is lower and dropping all the way to 9000.

my money is on the fact that it will prove to be a more powerful motor on the independent chassis dyno (and at the drag strip), regardless of the dyno charts published by the same group that is rating it as an even 500hp.

let's wait and see what shows up on an independent dyno. we know the displacement of the two is the same, but the updated motor has improved oiling and valvetrain that reduces parasitic losses to the tune of about 8hp. nevertheless, Porsche is advertising it as a clean 500hp. that's not to say it isn't higher than that.

Yes, they are ram air scoops on the sides with the RS. The GT3 has its intakes on the rear deck, but the RS does not (funnels air from the rear quarter panels).

Any difference there won't show up on the dyno - car needs to be traveling very fast to make a difference (not parked on engine dyno). Not sure how much more power the RS's intakes could add compared to the rear deck intakes of the GT3, but I'd be surprised if it was more than 1 to 5 hp and only when traveling near top speed.

More performance is more performance doesn't matter about your insensitive butt can read it or not!
The graphs are for guidance only as the actual power curves will be slightly different.
What's to take home for the 911.2 GT3 engine is that
1. Max torque is at 6000rpm instead of 6250rpm of the RS
2. Max rev of 9000 rpm instead of 8600rpm of the RS so one can stay in a gear longer and also at a higher torque point after shifting.

Even 0-60 times seem comprable.
Yes, you can stay in a gear longer alll the way down to the bottom of the power curve. Except for the Mulsane Straight or the high banks at Daytona I am unaware of any straights in the north east where you would run out to 9000 in 7th gear. Enlighten me if you know otherwise.
In vast majority of cases its a non issue and meanigless to most DE'ers and merely bragging rights you can rev to 9000 all the way down . Woohoo.
You discount and lost sight of the remaining areo and rear and front track advantage that remains with the RS likely more than offsetting the predominately irrelevant 400 rpm advantage of the .2
The real advantage of the .2 engine is what they do with it in the future. The real world peformance difference with this iteration seems non existant or neglible at best.
Cheerio.

Who cares about all of these statistics, let's get the heart of the matter. If I buy a 991.2GT3 road car, will I be able to beat my neighbor, driving his 991.1 GT3RS and my other neighbor, in his 996 Turbo to Whole Foods, which is 8.5 miles away from our houses? Couple of low speed sweepers and approximately 5 miles of highway? I'll go back and check the ratio calculators and transmission diagrams again. I have a feeling these guys are in for it this time. Mach Five Out!

Forget about these marketing graphs. The real power curves look different. The 991.1 RS has ists power peak at about 8100 rpm, the 3.8 at about 8400 rpm. Lets wait for the first dyno runs of the new one...

Your butt is obviously very very sensative. I don't think I could tell the difference from the seat of the pants based on the power curves above.

We are talking about the engine only...
What they will do in the future is anyone's guess and now I mean right now the 991.2 GT engine is the highest performance NA engine ever in a Porsche production car
Enjoy your RS and of course I like it too

I'm sure PAG made sure it's the "best" performing 4.0L they've sold even if by a hair. That is of course until the next GT 4.0 arrives.
It's all a major mind **** game with them to get you to transfer your wealth to their bank account.
