710PS Dodge Viper GTS by Geiger Cars

The project started on the older V10 8.4-liter naturally aspirated monster engine made entirely from aluminum and hand-crafted. It has received a re designed airbox along with a custom-made exhaust system equipped with tubular headers and sport catalysts. They also fiddled around with the motor’s ECU and in the end managed to squeeze a grand total of 710 PS (522 kW) at 6,100 rpm and 861 Nm (636 lb-ft) at 5,500 rpm which represents a significant increase over the standard 654 PS (481 kW) and 813 Nm (600 lb-ft).

As a result of the added power (which costs a hefty €11,900), the upgraded Dodge Viper GTS now accelerates to 62 mph (100 km/h) in 2.9 seconds and continues to accelerate until it hits a top speed of 212 mph (341 km/h).
