A while back GeigerCars unleashed a performance package for the Ford GT that featured a 3.3-liter supercharger producing 701 hp and 837 Nm of torque. Now they bring to the table a larger, 4.0-liter supercharged engine that also comes with a sport air filter, new throttle valves, re-tuned electronics, and a more efficient cooling system. This Ford GT received the nickname Geiger HP 790 from GeigerCars since the performance numbers show 790 hp and 863 Nm of torque from the 5.4-liter V8 motor. All the extra power under the hood allows the Ford GT to run a 0-100 km/h time in 3.6 seconds, 0-300 km/h in 22.8 seconds, and claim a top speed of 360 km/h.

Improving the visual appearance of the sports car is a custom developed coilover suspension kit that drops the Ford GT 60 mm. Underneath, GeigerCars installed an aftermarket exhaust system, and the exterior was painted a bright lime green color scheme. Matching the black racing stripes down the hood, roof, and rear of the car are matte black racing rims measuring 20×9 in the front, and 21×11 in the rear. The wheel package includes the Dunlop SP Sport Maxx high performance tires that many high class sports cars carry today.
