What a 300HP Boost Sounds Like

The 2021 Dodge Charger SRT^® Hellcat Redeye doesn’t really need a performance boost … but you only live once. Hennessey Performance Engineering gave this Charger Redeye an HPE1000 upgrade and say they can do so to any SRT Hellcat-powered Dodge vehicle. Along with the supercharger, the modification includes an upgraded pulley and the installation of stainless-steel long tube headers and high-flow catalytic converters. Hennessey says the boost gives the vehicle the potential to do 0-60 in just 2.8 seconds and can reach around 141 mph at the ¼-mile. Hennessey runs a chassis dyno test on the vehicle and does about 400 miles of road testing to validate these results. The performance upgrades on this 2021 Dodge Charger SRT Hellcat Redeye Widebody give it a 300HP boost.
