In the link on the first post this is what it said about the hood....
"A
newly designed, functional performance hood on both Charger SRT Hellcat Redeye and Hellcat models not only looks more sinister but provides maximum air intake to the supercharged HEMI from the functional hood scoop to boost power. This hood takes full advantage of the SRT Hellcat Redeye’s air intake system and is sealed to the airbox. The new performance hood, mail-slot grille opening, and airbox opening near the wheel liner combine to give the high-output engine an 18% greater air-flow rate than the SRT Hellcat engine (1,134 cubic feet per minute). At full power, this is the equivalent flow rate to 89 adults simultaneously emptying their lungs in one second."
