991.2 GT3 RS Mule

With the Variocam on both intake and exhaust now, there really isn't much trading of low-end to create more power on high-end anymore.
#230
No, I'm just assuming that the safety margins for the RS would need to be similar to the GT3 and that they would need to make 30hp more (even if both numbers are conservative - it would be too embarrassing to have the actual difference be only 10hp on the dyno, because the GT3 already makes 515hp...)
#231
I guess what I'm saying is...I agree with Dante on a 4.0 with ~530 @ 8,500 RPM; I expect both engines were developed simultaneously, and the GT3 was dialed back to 500 via ECU, so no need to add displacement or crazy RPM to get more power out of the engine.

From: The way to hell is paved by good intentions “Wenn ich Purist höre...entsichere ich meinen Browning” "Myths are fuel for marketing (and nowadays for flippers too,,,)" time to time is not sufficient to be a saint, you must be also an Hero
Then easy to tune GT3 to 530 HP
with a dundon catless easy 560HP
4L 560 hp sounds crazy with redline 9k max rpm
btw not to mention piston speed stroking

And I do not believe this is what happened...

That would be really sad (and unprecedented) if they electronically neutered the GT3. Porsche has never done that to a GT car before (GT4 has restrictive intake and exhaust, but not actually stifled like the 981.1 Boxster was compared to the Cayman and 3.4L S to 3.4L GTS to create an artificial difference, for examples).

I fully expect AP to regale us with some elaborate explanation as to the magic involved with the upcoming RS engine power increase so that it will not appear to be an ECU change. We'll see...to me it just seems too convenient that, with all of the changes to the new 4.0, it currently makes exactly the same numbers as the old one.

I think the .2 GT3 is being electronically neutered a bit, and Porsche can just release that neutering for the .2 RS, and bam the .2 RS gets 525 hp out of basically the same engine.

Exactly. Very suspicious for the new Motorsport GT3 engine with new architecture and all these new improvements described by AP, to make exactly the same HP and exactly the same torque as the 991.1 RS, and 997 RS 4.0.

Maybe I'm being naive, but I assumed they wouldn't do something as cynical as not opening the throttle all the way (which is how they cut 10hp from all the Boxster versions of the 981.1 compared to the Cayman) on a GT car.
All production cars are tuned with a large safety margin (to run on crappy fuel, etc.) and so it's no surprise that the GT4 makes more power with a tune alone (reducing the margin for error in ignition timing, etc.). But, so does every other Porsche model.
At 125hp/L before ram-air, even the conservative factory rating doesn't leave too much power on the table (if there was funny business, there certainly wasn't very much of it...).
