Power from the company’s 6.2-liter supercharged V8 engine has been bumped from 707 hp in Hellcat-spec to 840 hp for the Demon. This power boost has been achieved with the installation of a larger, 2.7-liter supercharger, boost pressure rising from 14.5 psi to 11.6 psi, new pistons, rods and valve train being installed and the implementation of two dual-stage fuel pumps. Further engine upgrades include lifting the rev limit from 6,200 rpm to 6,500 rpm, strengthening the connecting rods and incorporating three sources of intake air (the hood, driver-side headlamp and an inlet near the wheel liner).
What this amounts to is truly phenomenal straight-line performance. Zero to 60 mph (96 km/h) passes in just 2.3 seconds, the quarter-mile can be achieved in 9.65 seconds at 140 mph (225 km/h) and the Demon holds the Guinness World Record for first-ever front-wheel lift in a production car. What’s more, the Demon’s 1.8 g of acceleration is the highest of any production car.
