next carrera s is said to be getting 421ps (autocar)
combine it with PDK &sport+ and my estimations would be
Max speed 310 km/h
0-100 km/h 3.7 seconds
0-160 km/h 7.9 seconds
0-200 km/h 12.1 seconds
0-300 km/h 48.6 seconds (better Aerodynamic's)
Quarter mile 11.5 seconds
and as usual they will be claiming a conservative 4.1 seconds to 62mph (for pdk with sport+)when the car first hit the show..
BUT being light as a 09 gt3 (1370kg) & only 14ps down the 2011 carrera s with PDK combined with SPORT+ will smoke the 09 gt3 in strait line..
