German Tuner Ruf got their hands on a Porsche 911 and gave it a 3.8 liter flat-6 engine that gives the car 445 horsepower. That engine gives the Ruf Porsche RGT 911 the ability to do 0-60 mph in 4.2 seconds and 0-124 mph in 13.5 seconds along with top speeds of 196 mph. Ruf also gave the 911 some body work on the car to and included a six-speed gearbox with short-shift kit.
