When the embargo lifted on the 2023 Dodge Challenger SRT Demon 170 on Monday, we focused on key parts of the new package, including power, performance, and production numbers, but we didn’t get into how this package makes so much more power than the closely-related Redeye. Today, we dive into what makes the Demon 170’s supercharged Hemi so much more powerful—reaching 1,075 horsepower. (See our initial piece about the 1,025-horsepower, 8-second Demon 170).
When Tim Kuniskis introduced the 2023 Dodge Challenger SRT Demon 170 to a small group of media in early March, he held up a camshaft and said that it was the only component that was directly shared between the 6.2-liter Hemi in the Demon 170 and the 6.2-liter Hemi in the Redeye. Everything else was revised in some way, if not replaced altogether.
