Really? Don’t think its ever been 20hp for GT3 RS before. It’s been 0, 0, 15, 25, and now 20 (not including 997 RS 4.0 which was 65).
The only other time I remember 20hp from RS was 1973 (210hp vs 190hp in 911S which was 11% and lots more torque compared to current 4%).

I think the 992 will be turbo, but not because the 4.0 NA has no more to give.

As shocking as it sounds, the latter is rumored to ditch its naturally aspirated flat-six engine in favor of a more technologically advanced turbo unit. According to a Stuttgart-based source, quoted by Autocar, the 2020 911 GT3 and the more track-oriented 911 GT3 RS will adopt a heavily modified version of today's 3.8-liter twin-turbo boxer engine of the company.
According to the British magazine's intel with direct links to Porsche Motorsport, the new GT3 will have somewhere in the region of 513 horsepower (382 kilowatts), making it equally powerful to today's 911 GT3 RS. That would represent a healthy boost over the 493 hp (368 kW) of the current 911 GT3 and, most importantly, the torque will be significantly increased to approximately 524 pound-feet (710 Newton-meters).

“According to the British magazine's intel with direct links to Porsche Motorsport, the new GT3 will have somewhere in the region of 513 horsepower (382 kilowatts), making it equally powerful to today's 911 GT3 RS ... the torque will be significantly increased to approximately 524 pound-feet (710 Newton-meters).”
This implies a very weird power curve. Torque about same as GT2 RS, but 180hp less. It means lots of boost in low revs, but falling terribly as motor begins to rev.
I hope this isn’t true or it will feel like a diesel truck

I think there is a factual error in the information (like maybe 524 Nm instead of Foot-Pounds - Which is 386 Foot-Pounds). Current GT3 makes 460 Nm (339 Ft-Lbs)...

There is all sorts of boost trickery to manipulate curves also - think variable vanes, remapping, or electrically spooled and you have a lot of possibilities.
Whether it has lag will be what to look for...

A car with much more peak foot-pounds of torque than peak horsepower means it would drive like a truck motor or 60's American muscle car. We know Porsche does not want its GT car to drive this way. Even the GT2 RS is not close to this (power much higher than torque in ft-lbs). This allows the 2RS to make peak power near 7k rpm, not below 5k rpm like the specs leaked suggest. I have very high confidence that these are wrong.
Update- if Hp and Tq in Ft/Lbs were the same, peak Hp would come very low on the tach and there’d be no sense in a redline higher than 6,xxx rpm (with peak power made well below this point). The numbers in the prediction above show torque even higher relative to horsepower, pushing peak power even lower on the tach. Means torque curve would be falling rapidly well below 5,000 rpm (due to loss of boost or undersized turbochargers)

9500 rpm, 525hp, no cleaning lady.. just my best SWAG.
