2008 Techart GT Street Porsche 911 Turbo

German tuner Techart will use the Geneva auto show this year as the opportunity to unveil its latest creation: the GTstreet 911 Turbo. The stock 911 Turbo is, as you might imagine, already a ridiculously powerful machine with 480 horsepower and 457 lb-ft of torque. And any car that has been known around our office to cause Bluetooth headsets to fly off of ears and smack the rear window on acceleration runs must be quick.

But those numbers are small beans compared to the GTstreet, which manages to produce 630 horsepower and 604 lb-ft of torque by being tweaked within an inch of its life. This tuner terror can reach 60 mph in just 3.2 seconds on its way to a top speed in the neighborhood of 217 mph. To prevent the car from taking flight, Techart has fitted the GTstreet with an aggressive bodykit designed to increase downforce and reduce drag. Future owners are advised to secure their earpieces with duct tape.
