Some cars just don't need any tuning because they are perfect like the manufacturer delivers them. In our case , the Porsche Carrera GT is already the perfect supercar and its performances are impressive: the 5.7-liter V10 engine delivers 612 hp and generates a maximum torque of 590 Nm which makes it capable to sprint from 0 to 100 km/h (62 mph) in just 3.9 seconds while the top speed is limited to 334 km/h (207 mph) due to the safety reasons.
Although just 1,270 units of this car were built one unit went to the exclusivist tuner specialized in Porsche vehicles: 9ff.
After some modifications the tuner boosted the massive V10 engine to an impressive 900 hp!
These modifications changed entirely the performances of the vehicle: the sprint from 0-100 km/h (62 mph) is made in 3.2 seconds, 200 km/h (124 mph) are achieved in 8.5 seconds, 300 km/h (186 mph) in 17 seconds while the top speed is limited to 390 km/h (242 mph)!
All of you are wondering now which are the modifications brought by the tuner: well first of all a monocoque carbon fiber chassis was added, 19 inch magnesium wheels, a new set of high-performance ceramic brakes and a ceramic dual disk clutch.
Also a new carbon-fiber rear wing was added for better stability at very high speeds as well as a new suspension system which can lower the car using an electric system. Of course all these have a price: €452,000 or $635,000.
