Dario:
 

i m am comparing the engine of the 997.2 turbo/S vers the 991 turbo/s engine and since you are saying that the new 991 turbo S is from 200-300kmh almost 5-6 secs faster than 991 turbo (up to 200 kmh the gap is bretty small) with only 40hp difference i do question that. specialy in those speed range 200-300kmh were almost all the power is needed to over come drag 40hp doent make a 5+ secs gap.

So if we stay with your numbers 0-300kmh under 30 secs, so 991 turbos 560 is about equal to the 997 gt2 rs with 620hp... or the mp4-12c with 625 hp..

 

Maybe I should also add that while the 991 Turbo S engine is an improved version of the 997 Turbo S engine and based on it, practically no part, incl. the VTG chargers, is the same. All parts have been optimized and developers seem to be surprised how well the package works in the new car. Just as a little side note. This is not exactly the same engine from the 997 Turbo S, even it is based on it.
