Emissions controls are going to make inter generational HP gains much stricter especially in EU. If Donald keeps the cafe regs at tough guy mode and freezes the requirements I wonder if Porsche would give us a hot rod? Would be hilarious to have the "uncorked" version here in states vs the safe/sound down/ emissions down EU/ ROW version.

Interesting how all the new engines have this noticeable power drop up top. In the 991.2 Cup there's little benefit hugging the redline coz the pull noticeably weakens past 8k, despite the 8.5k redline. We use the final 3-400 revs only to save a shift...
There seems to be a similar case with the top 5-600 revs in the new RS. Guess we'll all know when we get our feet on the pedal!!
Must say I'm warming up to how all these little incremental changes are adding up to a bigger whole. From first hand experience, the .2 front axle development in the Cup is significant: so much that numerous drivers asked Michelin if they secretly changed the control tires on us this season

One of the 918 "flying doctors" was at Smokies GT3 event talking tonight, and he said there is no difference between those two engines, and then he told us not to tell anyone else. As soon as he said that, a German soldier in a WW2 SS uniform came out from behind the screen and shot him point blank.

Ram air intake and bigger tubes leading to the air box and tune to deal with the extra air.

Ram air cannot be counted towards the declared power numbers because it's not there in the first 1-2 gears, and the car should make promised power regardless of speed. But, yeah, it could be just different software, and I do not think it's a problem. Gt3 to RS difference is not about the engine in this generation.

according to Top Gear Magazine
"Right, I’ll attempt to keep this brief. Engine first. According to Andreas Preuninger, head of Porsche’s GT cars division, this is little short of a second generation version of the new 4.0-litre flat six. Power may only have climbed 20bhp, and torque by 7lb ft, but behind the figures there’s a new oil sump, wider conrods, improved oil supply, a larger crankshaft and revised valvetrain."
Autocar has some interesting details also, tho not regarding the engine

Agree- probably a remap and exhaust/intake plus assuming the RS slightly lighter than .2GT3
All I can say is I do not need any more power for the street. But - I did not think i would enjoy the .2 more on the street than the GT4; but I do. The extra torque is key plus the power is great. Also - every time I take her out is just feels so Special- it has an occasion

I'll be wrong but...revving and revving without additional power above 8250 rpm, wouldn't be surprised if they are leaving (more than) something on the table for further developements with this NA engine

New engine (solid lifters, cylinder coating, higher compression ratio etc), new aero - more downforce with same drag, new suspension - GT2RS hand-me-down, lots of software recalibrations (which are as important as hardware in modern cars), new brake cooling, also all the same changes .2 range had over .1 (e.g., better PDK, better steering feel), lighter front lift.

Sounds like my 991.2 GT3 engine, and Porsche has said it from day one that the 991.2 Gt3 engine is the same engine as the "endurance car" engine. I went to the Mortorsport Museum Tour last year and the engineer told me the same. We are already able to buy that engine now on a street car!
