With 530 ponies under the hood, or rather the rear axle, we imagine that few Porsche 911 GT2 owners will ever complain about lack of power. Still, horsepower-junkies can get their fix with Wimmer RS's latest tuning project amply named "GT2 Speed Bi-Turbo" which boasts a whopping 827HP and a top speed of 378km/h or 235mph.

The German tuner starts with the 911 GT2's 3.6-liter turbocharged boxer engine that receives a series of upgrades including a pair of high-performance turbochargers, a sport exhaust system, modified engine block and a new ECU. The result is an output of 827 horsepower at 7,400 rpm and a mind-blowing 948Nm or 699.2 lb-ft of torque.

Wimmer RS supports that the GT2 Speed Bi-Turbo sprints from standstill to 100km/h (62mph) in just 3.38 seconds and to 300km/h (187 mph) in 20.2 seconds, while maxing out at 378km/h (235mph).

The car also gets a set of 20-inch Sportec alloy rims wrapped in 235/30 R20 high-performance Dunlop tires up front and 325/25 R20 at the rear, along with H&R sport springs and carbon fiber exterior mirrors and a rear spoiler lip.

The price for the GT2 Speed Bi-Turbo has been set at €281,000 that comes to about US$424,000 at today's exchange rates.
