The Viper ACR is one of the fastest and most track-focused cars in the world. The crew at GeigerCars thought they could build on that.
ACR owners interested in going one better will have to shell out about $46,000 for the upgrades. Big money, but they are fairly substantial.
In stock form, the 8.4-liter naturally-aspirated V10 delivers 645 HP and 600 lb-ft of torque. Yhanks to better hydraulic lifters, pushrods, double valve springs, a high-lift camshaft, larger intake valves, custom headers, high-flow cats, a new exhaust and some ECU tuning, power now sits at a Ferrari F12tdf-rivalling 765 HP.
GeigerCars have also released a host of aerodynamic upgrades. Improving its already huge downforce is the new Extreme Aero Package that consists of an even more prominent front splitter, a beefed-up rear diffuser and new carbon fiber canards on the front bumper. A set of lightweight forged alloy wheels complete the upgrades.
