Rob Dahm’s 968-HP Hurricane-Swapped Charger Proves Stellantis’s Twin-Turbo Six Can Out-Muscle Its Old V8
Rob Dahm just put the Hurricane inline-six’s skeptics on notice. On November 1, the YouTuber and project-car veteran strapped his 2026 Dodge Charger Sixpack to a dyno and watched it make 968 horsepower and 863 lb-ft of torque at the wheels, nearly double the 550 hp the twin-turbo 3.0-liter engine makes stock in Scat Pack Plus trim. He did it without opening the engine once.
That last part is the headline. Every one of those extra horses came from bolt-on turbo work, E85 fuel, and tuning layered onto a factory short block with its stock internals still inside. For an engine that Dodge loyalists have spent two years treating as a placeholder for the supercharged Hemi, a single-turbo build flirting with four-figure power on unopened internals is a hard thing to wave off.
How Dahm Got The Hurricane To Nearly 1,000 Horsepower
Dahm ditched the factory twin-turbo setup for a single Turbosmart 7275 turbo, feeding it through a CPC Manufacturing billet intake manifold. A secondary fuel rail kept E85 flowing under heavy boost, fed by a Fuel Lab surge tank mounted where the passenger seat used to be. With the full exhaust still attached, the Charger made 848 hp at the wheels, a figure Dahm attributed to exhaust backpressure holding it back. Pulling the exhaust off bumped that to 920 hp at 40 psi of boost. The final pull added a shot of nitrous on top of 46 psi, landing the car at roughly 968 hp and 863 lb-ft at the wheels.
The Transmission Tapped Out Before The Engine Did
Dahm never touched the eight-speed automatic’s programming, and the transmission’s own safety protocols ended up capping the run. Even in manual mode, it sensed the boost climbing and shifted itself from sixth gear into seventh rather than risk destroying its internals. The gearbox survived the ordeal and the car remained fully drivable afterward, but the self-preservation shift made one thing clear: the stock-block Hurricane had more to give. Transmission tuning, not engine hardware, is now the only thing standing between this Charger and a four-figure number on the dyno sheet.
What This Means For Dodge’s Inline-Six Gamble
Dodge enthusiasts have spent two years grumbling about the Hurricane as a consolation prize for the supercharged Hemi, especially with reports pointing to a 2028 Charger SRT Hellcat reviving the 6.2-liter V8 at somewhere around 700 to 800 horsepower. That engine will still own the sound and theater a turbocharged six can’t fake. But Dahm’s build argues the Hurricane was never just a stopgap. A factory short block, available in dealer lots right now, is already closing in on territory the next Hellcat won’t touch without its own supercharger upgrade. Whether that sways Hemi loyalists remains to be seen, but for the tuner crowd building on what Dodge already sells, the case for taking the Hurricane seriously just got a lot stronger.
