Dennis brought us his Whipple supercharged 2013 Jeep Grand Cherokee SRT8 to add a ground-pounding idle and get the 6.4L Hemi making safe power with less boost! Build details below:
Performed by us:
• COMP Cams
valve seats, valve seals, valve springs, valve retainers & locks
• MDS delete utilizing OEM Mopar components
• OEM Hellcat lifters
• OEM Hellcat engine oil pump
• All the miscellaneous OEM and aftermarket odds-and-ends to bring it all together.
With the mechanical work wrapped up in the shop by Dom, John 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 6.4L Hemi's output to 639.52whp & 533.48lbft! Perfectly safe power for the stock bottom end, with less boost pressure, and that ground-pounding idle Dennis was after!
