Doubt they would put the RSR 4.2L into a road car without restrictions. Does the current RSR have to comply with emissions and other standards?
KERS gives you the power burst without complex engine tuning and emissions management beyond what they already comply with.
It is fun we can have this debate.. Porsche have all the bits. 918 hybrid and KERS, strong ICE high reving flat six, ability to increase displacement, already made space in the chassis for this (battery and fly wheel). The question is timing and exact launch sequence.

None at 800 but, there are plenty over 700. The 2RS could get to 900 with this technology.

There were a couple of spy videos earlier this year of the 992 GT3 with this electrical whine and then it stopped with the latest spy videos all sounding like just an NA engine. My guess - they tested KERS but went back to just NA for 992.1 GT3. Maybe RS will get KERS? Or maybe have to wait till 992.2.

Will the 992 GT2RS launch at the same time as the 992 GT3RS? I’m curious, if the 992 3RS gets KERS and it adds 200HP/TQ that would seriously threaten the 991.2 GT2RS. I’m wondering if Porsche would do that, unless they plan to do a KERS 992 GT2RS around the same time?
On the other hand, there is serious competition from other brands, which may force the issue.
In any case, a 992 GT3RS with a 200HP/TQ boost from KERS, while maintaining a screaming 9k rpm N/A flat 6 would be ridiculously awesome.

I have a UK 991.3GT3 RS with OPFs and my butt dyno says it has more power compared to the pre OPF RS..JCR exhausts have dynoed both 991.2GT3 RS and 991.3GT3 RS OPFs which clearly showed that the later OPF RS has over 10 HP more than the non OPF/ITBs RS.

the Kers is unbeatable at track, technology is mature and cheap, 30kg 50kg are not a drama of weight for a light one, emissions and mpg are more stringent, keeping a 4.2liters at 9krpms is more troublemaker than a changeable external to the engine Kers,
why not?

The prior iteration of the 911 RSR won Le Mans GTE Pro in 2018, as well as the Super Season titles for the 18-19 season; the platform also won in GTE Am in 2019. Meanwhile, the 911 RSR won the IMSA titles as well, along with class victories at Sebring and Watkins Glen, among other venues (Long Beach, Mid-Ohio, VIR, Mosport).
Furthermore, the updated 4.2L RSR holds first and second in the GTE Pro category for the 19-20 season and will make its IMSA debut at Daytona.
None of the cars against which the Porsches compete have KERS or any other form of hybridization - the GTE rulebook forbids it.
As far as road cars go, PAG will probably do what it usually does: arrive later than others with a refined utilization of technology in a car that seems a bit disappointing in terms of its on paper inputs. The real life outputs will likely be stellar.

There won’t be a 4.2L. Porsche has to meet Euro 7 (even more strict than Euro 6d what we have atm). Euro 7 isn’t achievable while running the 4.2 with the current OPF technology. My guess would be 992 GT3 will be most likely the same Engine as the 991.2RS batch 2. The RS will be a Hybrid or Turbo. If you think about the HP difference between 997 and 991... 450 to 500HP (I don’t consider the 4.0 a „normal GT3RS“) the 992 GT3RS should have around 570HP. This is not possible with the current emission laws and there won’t be a separate engine for the US market. The way the Automotive industry is heading will be quite depressive for any enthusiast...IMO they are pushing the wrong buttons. There are many things which produce much much more co2 than the Automotive industry. A friend of mine did a scientific research on how things would change if everyone would drive Electric or Hydrogen cars and it wouldn’t really effect anything or at least nothing actually noticeable
