2023 Dodge Challenger SRT Hellcat - Supercharged 800WHP Street King
2023 Dodge Challenger SRT Hellcat (Widebody)
About This Build
The final year Hellcat needed a proper sendoff. The 6.2 supercharged HEMI has massive headroom with simple mods. Lethal Performance upper pulley swap increases boost from the IHI supercharger. American Racing long tubes and no-cat midpipe unleash the exhaust. JLT catch can keeps oil out of the intake. HP Tuners custom tune on 93 octane brings it all together at 800whp. Nitto NT555 tires actually put the power down. The sound alone is worth the build.
