Grand Cherokee | Jeep | Make : November 24, 2021
Carl brought us his 2014 Jeep Grand Cherokee SRT to have the 6.4L Hemi built and boosted! Setup below:
• Better Built Performance 426cid short block
• Whipple Superchargers 2.9L W175ax twin-screw supercharger system
• Whipple Superchargers 3.125" upper supercharger pulley
• ATI Performance Products 6% overdrive harmonic balancer
• MSD Performance fuel pump voltage booster
• NGK Spark Plugs LZTR7AIX spark plugs
• MotoRad 180° thermostat
• OEM Mopar Hellcat engine oil pump
• Gates HD Fleetrunner Micro-V "Green" belt
• All the miscellaneous OEM and aftermarket components to bring it all together
With the mechanical work wrapped up in the shop by TJ, John strapped her down to rollers for a custom calibration by Vlad via HP Tuners. With 93 octane in the tank, and the Whipple W175ax delivering ~9psi, output increased to a conservative 622.20whp & 597.66lbft! And even better, this setup has a LOT more jam in the jar when Carl gets the itch for more!
