All the way in from Florida, Samuel brought us his 2018 Dodge Charger SRT Hellcat to get her turned up to 800whp!

Up first in the shop, John strapped her down for pre-work dyno runs to establish our starting point, coming in at 643.65whp & 616.15lbft. From there, TJ set the supercharged 6.2L HEMI up with an air-intake system from JLT Performance, 2.75″ upper supercharger pulley & billet idler from Metco Motorsports, a Gates HD Fleetrunner Micro-V “Green” serpentine belt, along with a pinned harmonic balancer for extra assurance, a set of 2.00″ primary diameter long-tube headers from Stainless Works, OEM Dodge Demon fuel injectors, and a 180° thermostat from MotoRad.

With the mechanical work wrapped in the shop, John strapped her back down to the rollers for Vlad to perform a custom calibration via HP Tuners. With 93 octane in the tank, and the IHI 2.4L supercharger delivering 15psi, Vlad increased output to 803.80whp & 751.63lbft -- a gain of 160.15whp & 135.48lbft! From there, Samuel picked her up for the long drive home, and has been having a blast back home in Florida!
