GeigerCars Ford Mustang Shelby GT500

Alongside the Ford Mustang V6 and its V8 brother Mustang GT there is the crowning glory of the series the wild Mustang Shelby GT500, which is equipped ex factory with 540 PS, an aggressive body and traditional double stripe paintwork. Anyone who remembers the American racing legend Carroll Shelby will be able to instantly imagine how uncompromising and purist the Shelby GT500 factory settings already are. The US car specialist Karl Geiger from Munich has now got its hands on this vehicle and take a look at how the upright Cobra has been transformed into an almost untamable monster!

As usual the engineers at from Munich operated on the open V8 heart of the American muscle car and in the process left no stone unturned. For more pressure they donated a 3.3 litre compressor to the 5.4 litre aluminium engine block which with its 1.6 bar supercharging pressure provides real fire in the forged crank drive. Larger throttle valves, a modified injection system, a 100 millimetre air flow meter and machined cylinder heads also guarantee that the inner organs are fine tuned. Additional coolers for charge air, coolant and engine oil ensure that the eight cylinder can always work at the perfect temperature range despite massively increased power. Thanks to the massive changes the Geiger Mustang Shelby GT now generates a legendary 810 PS at 6,700 rpm, whereas the maximum engine torque of 945 Nm at approx. 4,300 rpm pulls on the increased differentials. Of course with so much engine torque the transmission also had to be reinforced and in the same step its 5th and 6th gears were shortened. A 3 disc carbon clutch produces smooth power transmission. A special manifold with racing catalytic converters and customized sport exhaust guarantee that exhaust gases are disposed of properly according to type.

So that so much power can also be transformed in acceleration, fitted the Shelby with a special racing chassis as well as a Panhard rod made from chrome-moly steel including polyurethane bushes on the ends to balance the axial offset and new reinforced and adjustable trailing arms for improved rear axle directional stability. For the all-important contact to the asphat surface four classic OZ alloy wheels in 8.5 and 10x20 inch guarantee adequate grip thanks to Michelin high performance tires in 245/35ZR20 and 285/30ZR20. The upright Cobra is slowed down using 6 piston high performance brakes on the front axle with 380 millimetre large drilled or optionally slotted brake discs.
