2018 Jeep Grand Cherokee Trackhawk – 800 HP

Grand Cherokee | Jeep : March 28, 2020

Martin brought us his daily driven 2018 Jeep Grand Cherokee Trackhawk to get it breathing easier, making more boost, and put on ethanol!

Up first, Archer removed the supercharger snout for porting by Kong Performance matched to their 112mm throttle body, then once returned, moved on to installing a 2.85" upper supercharger pulley and billet idler from Metco Motorsports, ID1300x fuel injectors from Injector Dynamics, Boost-a-Pump from Kenne Bell Superchargers, a set of 2.00" primary OD long-tube headers from Kooks Headers and Exhaust, 180° thermostat from Mishimoto Automotive, all topped off with a set of Pro-Kit lowering springs from Eibach.

With the mechanical work wrapped in the shop, John strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners. Up first with 93 octane in the tank, Vlad increased output to 764.78awhp & 706.84lbft. Then, after a quick change to E85, Vlad dialed in the ethanol calibration, increasing output to 810.29awhp & 744.63lbft! With both calibrations stored on his laptop, Martin can switch back and forth based on his needs using his MPVI2. Martin now has himself one seriously badass daily driver!
