The Dodge Viper is headed to an ignominious ending but in fairness to Dodge, the American automaker is making sure that the Viper is going out with a bang. A slew of special edition models based on the Viper ACR have sold out in record time, proving that the Viper collector market is alive and healthy. Sadly, those special editions were of limited quantity so not everyone got the chance to own one. Fret not though because there’s another way to get a non-standard Viper ACR, one that involves taking the aftermarket route. It just so happens that Geiger Cars has just unveiled its new program for the Viper ACR that comes with a performance upgrade that spikes the 8.4-liter V-10’s engine to 765 horsepower and 679 pound-feet of torque.
