It is completely stock, and can still go 219 mph on Johnny Bohmer Proving Grounds.
Although we’ve seen many cars, including the Porsche 911 GT2RS, take to the Space Shuttle runway with Johnny Bohmer Proving Grounds before this one does it better than others. It’s not only the fastest stock GT2 RS to run the 2.7-mile stretch but it’s also faster than it. The speedometer shows that the Porsche driver is at 219 mph (3522.4 km/h), which is a speed significantly faster than Porsche’s official speed record.
The conditions at Florida’s runway may have allowed this GT2 RS to perform better. The video shows temperatures in the mid-70s F (mid-20s C), with humidity between 60 to 70%. The Atlantic Ocean is right next to the runway so that makes it quite low for the area. This means that the runway is almost at sea level for maximum aerodynamic density. The runway’s flatness makes it easy to see the elevation change only one quarter inch along the entire 3.2-mile stretch of asphalt. This runway was built to be used by spacecraft, which means that terrestrial-based vehicles can shine here.
The Porsche shines. Although it is listed as having no modifications to it, the GT2 RS still delivers 690 horsepower (515 kilowatts). This is thanks to its twin-turbocharged 3.8 liter flat-six engine. It seems to launch fairly well, though with a manufacturer-published 0-60 time of 2.7 seconds, this specific car seems a bit slow off the line. The speedometer climbs steadily to triple digits from there, reaching 100 mph within 7 seconds, 150 in 15 seconds and 200 in 29 seconds. It slows down to 200 mph, but then it climbs steadily to 215 miles per hour.
If the driver had stayed on the throttle for the entire 3.2-mile distance, the 911 might have been able to reach 220 mph. The runway only 2.7 miles is used for speed and the GT2 RS required most of that runway to pull up. However, 219 mph doesn’t seem to be slow at all.
