Porsche 997 Turbo Cabriolet By 9ff: 912 hp !!
The 997 Turbo Cabriolet was only officially launched by Porsche this month and tuning specialist 9ff already released a high performance tuning pack wich delivers 912hp. 9ff's engineers used the same kit that was used on the Carrera GT and 911 Coupe. Their 650hp strong version of the Turbo managed to reach a maximum speed of 350km/u and it is believed that this more powerful car will pass the amazingly speed of 400km/u.
