Geiger Cars 2010 Ford Mustang Shelby GT500

The 2010 Ford Mustang Shelby GT500 features a host of additions and changes, most notably an aluminum block and some weight saving measures that result in improved performance over the previous model. But for some folks, better is just not enough.

Karl Geiger of Geiger Cars is there for those folks. He has added to the already impressive GT500 a bigger Whipple supercharger, larger throttle valves, a better fuel injection system, and ported heads. These improvements result in a mighty impressive 799 hp and 697 lb-ft of torque. Top speed is a claimed 220, which seems a little on the high side to us.

All that whoa is backed up with a three disc carbon clutch and reinforced six speed transmission. Handling is improved thanks to a "racing chassis," panhard rod, polyurethane bushings and adjustable lower control arms. Brakes are 15 inchers with six pistons. Check out the press release below for all the details.

Press Release

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 untameable monster!

810 PS, 945 Nm engine torque

As usual the engineers at GeigerCars.de 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 customised sport exhaust guarantee that exhaust gases are disposed of properly according to type.

High end chassis engineering

So that so much power can also be transformed in acceleration, GeigerCars.de 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 asphalt surface four classic OZ alloy wheels in 8.5 and 10x20 inch guarantee adequate grip thanks to Michelin high performance tyres 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.

Perhaps this Mustang Shelby version would also put the fear of God into the US racing legend Carroll Shelby!
