With the right tuning and modification, fast sports cars can become faster. Even a Porsche 911 Turbo S has been subject of such modifications. Recently though, a 2014 Porsche 911 Turbo showed the result of its modifications by going as fast as 222 miles per hour during a speed test in Florida.
Modified Porsche 911 Turbo Hits Top Speed Of 222 MPH
The object of this speed test – one of the many conducted by Johnny Bohmer Proving Grounds (JBPG) – is a green yet mean 2014 Porsche 911 Turbo that features a number of multiple prototype manufacturer parts. Its 3.8-liter twin-turbo flat 6 engine has been tuned by TPC Racing to 700 hp of max output and 571 Ib.-ft. of peak torque.
As the video shows, the modified 911 Turbo started slowly. This move (sandbagging) was intentional since the 911 Turbo has to cross the IMRA (International Mile Racing Association) speed traps at the end of the 2.7-mile test distance at the top of its final gear. Upon crossing the finish line, it recorded a top speed of 222.337 mph.
Greater Than Factory 911
The specs for this modified 2014 Porsche 911 Turbo greatly surpasses the factory version. The twin-turbocharged flat-6 of a 2014 911 Turbo is factory-tuned to 520 hp of max output and 487 lb.-ft. of peak torque. This is just good for a top speed of 196 mph.
To determine how fast the modified Porsche could go, it was made to speed through a distance of 2.7 miles on the three-mile-long concrete runway in Merritt Island, Florida. This distance is just enough for a car such as a 911 to reach its top speed, just like when JBPG tested a Dodge Viper to its fastest pace at 253 mph.
Should've Been Faster?
Comments say the modified 2014 Porsche 911 Turbo was still accelerating when it passed the finish line – it could have surpassed 222 mph if it accelerated quickly enough from the start. But since JBPG already determined that the car was at its gearing limit when it crossed the line, the figure should be reliable.
