As Dodge wound down production of its most unhinged sports car, D3 Performance Engineering decided the Viper deserved a proper send-off. Starting with a track-focused Gen V ACR, the shop added an F1X Procharger and a Nitrous Express kit to push the V10 past 900 horsepower, then took the car to the most demanding stretch of asphalt in the world to prove it. The result: D3 now holds the record for the quickest Gen V Viper on earth.
