Engine build time-lapse 840-hp Dodge Demon Hemi V-8 | Redline Rebuilds - S3E1

We love doing Redline Rebuilds (almost) as much as you enjoy watching them. And when Dodge offered up the supercharged, 840-hp, Hemi V-8 out of a Challenger SRT Demon for our magical time-lapse treatment, we couldn’t say yes fast enough. Be sure to stick around until the end to watch us put that power to the ground.
