If there was ever a Porsche 911 you didn’t want to mess with in a straight line, it would have to be this 9ff-tuned model.

During a recent SCC500 event, this so-called “GTurbo R” managed to hit 332,38 km/h (206,53 mph), which isn’t all that surprising when you consider its maxim output of 1,200 horses and roughly 1,100 Nm (811 lb-ft) of torque.

9ff unveiled their GTurbo 1200 power kit for the Porsche 997 back in 2010, when we also learned that once modified, such a car could sprint to 60 mph (96 km/h) in 2.8 seconds and max out at 400 km/h (248 mph).

The video below represents a sort of “sights and sounds” when it comes to this particular GTurbo. You get to hear it idle and accelerate, and ultimately race against a Nissan GT-R toward the end of the clip.

Thing is, this isn’t the most powerful tuned 911 we’ve ever seen in action. That title goes to this 1,500 HP Porsche 911 Turbo TR1500 from Russia.
