2018 Dodge Challenger – Comp Cam Install

Jim brought us his 2018 Dodge Challenger R/T with two goals in mind, improve the Hemi growl and get the 5.7L sitting over the 400whp mark!
Up first in the shop, John removed the factory ECU so that it could be overnighted to HP Tuners and unlocked for calibration, and then moved on to tearing the Challenger down for some engine work in preparation for letting those bald eagles fly! Modifications below:

With the mechanical work wrapped up in the shop by Alex, Matt strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners. With 93 octane in the tank, Vlad increased the 5.7L's output to 427.71whp & 418.74lbft! With an initial baseline of 360.07whp & 393.16, this '18 Challenger R/T got a nice jump in power that Jim is sure to enjoy!
