With our Stage 1 Hellcat package installed, 93 octane in the tank, and over 800whp on tap now, Frank’s 2017 Dodge Challenger SRT Hellcat left the shop with a bit more jam! Modifications below:
Performed by us:
• TBA Machine 2.85″ upper supercharger pulley
• TBA Machine Hellcat 3″ dual bearing supercharger idler pulley
• MotoRad 180° thermostat
• Gates Corporation HD Fleetrunner Micro-V “Green” belt
• NGK Spark Plugs LFR7AIX spark plugs
With the mechanical work wrapped in the shop by John, Matt 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 829.04whp & 718.81lbft — some killer gains from a bolt-on package!
