O.CT Tuning company has performed several upgrades on the SRT8 versions of the Jeep Grand Cherokee and Dodge Challenger.
Work began on the V8 6.4-liter HEMI engine which in its standard delivers 477 HP and a peak torque of 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 HP and 542 lb-ft. Upon request, O.CT Tuning can make additional modifications to increase power over 600 HP.
The Dodge Challenger SRT8 OCTSRT8-700 seen in these images features the same V8 HEMI engine but the client wanted even more muscle so displacement was increased to 7.0 liters which lifted power to no less than 720 HP and 645 lb-ft.
O.CT Tuning is also offering a compressor upgrade for the Dodge Ram 1500 equipped with the V8 5.7-liter HEMI engine.
