German Porsche tuner 9ff has revealed their new 9ff GTurbo 1200 based on a Porsche 911 (997) GT3 which has 1,200hp and 1,150Nm of torque making it one of the most powerful Porsches in the world. It only needs 3.3 seconds from naught to 100km/h and goes all way up to a top speed of 403km/h. And it is street legal.
It is powered by a 3.8 liter flat six engine whose displacement has been increased to 3.9 liters. 9ff added a Garrett GT1200R turbocharger with ball bearings and water cooling. A three stage boost control is operated via buttons on the steering wheel, selecting from 0.8 bar, 1.2 bar and 1.6 bar hence adjusting the power output from 600 horsepower to a maximum 1200 horsepower.
