A company located in Germany named GeigerCars has customized a Mustang that they call the GT 520. The precision-machining of both cylinder heads, installing sport camshafts and reinforcing the valvetrain are part of the power treatment as is a belt-driven supercharger with carefully dimensioned intercooler.
A fully stainless-steel high-performance sport exhaust system with high-performance manifold and metal catalysts round out the engine conversion. The power has increased to 520 horsepwer and 415 ft-lb of torque. The GT 520 has recorded a 0-60 time of 4.2 seconds and has a top speed of 178 mph which is perfect for the Autobahn.
