Rob Dahm modified a 2026 Dodge Charger Sixpack, increasing the output of its 3.0-liter twin-turbocharged inline-six engine. The car now produces 968 hp and 863 lb-ft of torque, compared to the stock version's 550 hp and 531 lb-ft.
The modifications included replacing the twin-turbo setup with a single large turbo, installing a billet intake manifold, and using E85 fuel. The boost was increased to 46 psi, and nitrous was added to reach the peak power figure.
Before the addition of nitrous and with the full exhaust system, the vehicle generated nearly 850 hp. The engine block and internal components remain stock throughout the tuning process.
During dyno testing, the factory eight-speed transmission exhibited irregular shifting patterns under the increased load. Despite these issues, the transmission remained functional after the testing sessions.
