German tuning company Geiger Cars has tried its hand at improving the record-breaking 2016 Dodge Viper ACR, developing a suite of engine upgrades for the soon-to-be-terminated sportscar’s 8.4-liter V10 engine.
Geiger, if you didn’t already know, is a purveyor of grey market American cars in Germany and throughout Europe. They are well-known for their tuned versions of domestic performance cars like the Corvette and Camaro, so it’s no surprise to see them put their own take on the coveted ACR.
The company’s upgrade kit for the car includes an ECU tune, ported and polished cylinder heads, upgraded pushrods, lifters and valve springs and 2.215-inch diameter intake valves. Headers, sports catalytic converters and a stainless steel sports exhaust system are also added for improved performance and sound. All in all, the kit boosts the 8.4-liter V10’s output by 220 horses and 79 pound-feet of torque for a grand total of 765 horsepower and 679 lb-ft.
Geiger has also applied aftermarket forged 19-inch wheels with working tire pressure sensors. Their shop car was delivered with Dodge’s Extreme Aero Kit, which includes a front splitter and dive planes, a more aggressive rear diffuser and a large carbon fiber rear wing.
Adding these improvements to the ACR will run you €40,775, about $46,000 USD. Geiger will also source you a Dodge ACR in Europe and install the kit on that car, selling the entire thing to you for €219,000, or about $246,800 USD.
