It’s been a while since we last heard about the German tuner of American cars, GeigerCars. But now that the 2011 Ford Mustang is out they’re right back at it, coming back with awesome packages for both coupe and convertible ‘Stangs. For a start, they put a 2.3 litres superchargers with pressure of 0.5 bar on the car’s 5.0 liter V8 engine.

With a bit adjustments here and there, the power has gone up from the stock 412 hp to 497 hp, and the torque from 529 to 634 Newton metres. They’ve also removed the top speed limiter so it can now do 274 km/h.

The Germans also tweak the chassis and make it more sporty, and bolt a set of OZ Ultraleggera light-metal wheel under it with size of 8.5×20 and 10×20 inches wrapped in 245/35R20 high-performance tires at front and 285/30R20 at the back.
