The supercharged 6.2 L Hemi V8 from a Dodge Challenger SRT Demon is an amazing engine. It produces 840 horsepower (626 kW) and 770 lb-ft (1044 Nm) of torque on 100 octane fuel. The engine features upgraded internals, 2.7 L supercharger that makes 14.5 psi of boost, and two fuel pumps. Watch as Davin Reckow from Redline Rebuild rebuilds one of Chrysler’s most iconic engines.
