Vin Diesel 2018 Dodge Challenger SRT Demon – Video
The heart of the 2018 Dodge Challenger SRT Demon is the supercharged 6.2-liter HEMI Demon V-8, rated at 840 horsepower and 770 pounds-feet of torque. The red-painted Demon engine has been certified to the SAE J1349 industry standard for its horsepower and torque ratings. The engine also meets all applicable legal emissions regulations.
While the Demon V-8 shares its architecture with the 707-hp 6.2-liter supercharged HEMI Hellcat V-8, it is not simply a Hellcat engine with more boost. The Demon V-8 engine has 25 major component upgrades from the Hellcat engine, including supercharger, pistons, rods, valve train and fuel injection system.
Among the changes, compared with the Hellcat V-8, the Demon’s supercharged V-8 features:
Larger supercharger: 2.7 liters versus 2.4 liters
Increased boost pressure: 14.5 psi versus 11.6 psi
Higher rpm limit: 6,500 rpm versus 6,200 rpm
Fuel: Two dual-stage fuel pumps versus one
Larger induction air box with three sources of intake air: Air-Grabber™ hood, driver-side Air-Catcher™ headlamp and an inlet near the wheel liner
In addition, the HEMI Demon V-8 includes a high-speed valvetrain, strengthened connecting rods and pistons, and improved lubrication system. The upgrades enable the engine to sustain higher output and pressures while meeting FCA US LLC’s stringent durability requirements.
One key to the Challenger SRT Demon’s best-ever power output is air – the supercharged Demon V-8 takes in plenty of it. The SRT Demon’s Air-Grabber™ hood includes the largest functional hood scoop (45.2 square inches) of any production car.
