Tuned: 9ff GTurbo 1200 Porsche 911 GT3

Feel that your Porsche 911 GT3 is not fast enough? Well, German tuner 9ff might be able to help. For a price, 9ff will transform your 911 GT3 into the world’s most powerful and quickest Porsche. Called the 9ff GTurbo 1200, the figures are staggering: 1200 horsepower (895 kW) and 1150 Nm of torque, 0-100 kph in 3.3 seconds, 0-300 kph in 13.4 seconds and a neck wrecking top speed of 403 km/h!

Based on the Porsche 997 GT3 / GT3 RS, the 3.6/3,8 litre flat-six boxer engine is completely striped down and rebuilt with an almost endless list of 9ff strengthening parts, larger turbos and a displacement increment to 3.9 litres.

At the touch of a button on the steering wheel, the driver can select from the three different boost pressure of 0.8 bar, 1.2 bar and 1.6 bar, adjusting the power output from 600 horsepower to the maximum 1200 horsepower.

And the best thing about the 9ff GTurbo 1200? It is completely street legal.
