Challenger | Dodge : February 28, 2020
Bob brought us his 2016 Dodge Challenger SRT 392 to have her put under some pressure! Up first in the shop, Andrew set the 6.4L HEMI up with a Stage-II 2.9L W175AX twin-screw unit from Whipple Superchargers, including their upgraded air-intake system, along with the miscellaneous OEM and aftermarket odds-and-ends to bring it all together.
Then, Matt strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners. With the Whipple 2.9L delivering 8psi, Vlad increased the 392's output to a repeatable 652.15whp & 602.42lbft! Considering these cars normally baseline around 400whp & 385lbft on our dyno, that’s a gain over 250whp & 200lbft! Pretty impressive considering this car has 100% factory exhaust system in place.
