680hp Porsche 911 GT2 goes up to 221 mph

As if the Porsche 911 GT2 wasn't fast enough in stock form, German tuning house Wimmer Racing Technology has unveiled a new €30,000 ($40,000) package for the Stuttgart supercar to take its already superlative performance to stratospheric levels.

With a re-calibrated ECU, upgraded turbos, new cylinder heads, camshafts and a custom exhaust, the Wimmer RS GT2 produces a whopping 680 horsepower and 642 lb-ft of torque, capable of propelling the twin-turbo rocket up to sixty in a scant 3.4 seconds on its way to a top speed of 221 mph. Accompanying the engine mods are a carbon-fiber aero kit, H&R suspension and 20-inch Sportec wheels.
