2015 Dodge Challenger Scat Pack – Camshaft

Challenger | Dodge : January 14, 2020

Matthew brought us his Sublime Green 2015 Dodge Challenger R/T Scat Pack to get the 6.4L Hemi breathing a lot better and thumping a lot harder! Up first, Alex installed a custom VVT camshaft from Cam Motion, supporting valvetrain components from COMP Cams & Manley Performance Products, Inc., engine oil pump from Melling Performance Parts, mid-pipe from Stainless Works, aluminum radiator and 180° thermostat from Mishimoto Automotive, OEM Hellcat 92mm throttle body, along with OEM Mopar components to delete MDS, and all the miscellaneous OEM odds-and-ends to complete the installation, all breathing through the existing Mopar Performance air-intake system.

With the mechanical work wrapped in the shop, Matt strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners. The results? Even with the factory exhaust manifolds in place, Vlad still increased the 6.4L Hemi’s output to 472.40whp & 482.77lbft — that’s a gain of 70whp+ & 80lbft+ over what these cars normally put down in stock form on our dynos! Solid outcome all around.
