I wrote down the following: Porsche 964 (1988–1994) 360 hp 3.6l 4.8 s Porsche 993 Turbo (1993–1998) 430 hp 3.6l 4.5 s Porsche 996 Turbo S(1997–2006) 450 hp 3.6l 4.2 s Porsche 997 Turbo S (from 2004) 530 hp 3.8l 3.3 s Porsche 991 Turbo S (from 2011) 560 hp 3.8l 3.1 s Formula 1 2013 2.5 s If you want to continue the previous increases consistently, you would have to use the following: 700 hp for 2.9 sec. (Lamborghini Aventador) 6.5l 1000 hp for 2.5 sec. (Bugatti Veyron) 8l We Will we still experience the 1000hp 11 turbo with 10+ cylinders? Or will the end of the flagpole be reached first? What do you think?
