Jeep Grand Cherokee SRT8 and Dodge Challenger SRT8 tweaked by O.CT Tuning

O.CT Tuning has performed several upgrades on the SRT8 versions of the Jeep Grand Cherokee and Dodge Challenger.

Work started on the V8 6.4-liter HEMI engine which in its standard configuration delivers 477 PS (350 kW) and a peak torque of 637 Nm (470 lb-ft). The motor received a custom compressor kit and a charge air cooler system along with a software optimization that have bumped output to 564 PS (415 kW) and 735 Nm (542 lb-ft). Upon request, O.CT Tuning can make additional modifications to increase power beyond the 600 PS (441 kW) mark.
