PP-Performance has just delivered the fastest Porsche 911 in the world (as far as we know). The 3.8-litre turbocharged engine was uprated from 520 hp and 660 Nm of torque to 670 hp and 820 Nm of torque. Thanks to this boost, it can hit 100 km/h in a Bugatti Veyron rivaling 2.5 seconds and then hit 193 km/h in just 8.2 seconds. In the video below, you will see a PP-Performance Porsche 911 Turbo complete the quarter-mile in just 9.8 seconds at an astounding 221 km/h. The performance improvement was achieved by installing 3-to-1 headers, downpipes, x-pipe, high-performance filters and a PP-performance racing box. Total cost of the upgrade? A decent 12,000 Euros.
