O.CT Tuning has been developing several upgrades for the SRT8 versions of the Jeep Grand Cherokee and Dodge Challenger, which were incredible rides to begin with. The V8 6.4-liter HEMI engine delivers 477 PS (350 kW) and 637 Nm (470 lb-ft) in its standard configuration, but the tuner decided to add a custom compressor kit and a charge air cooler system along with a software optimization. This means that the V8 now develops 564 PS (415 kW) and 735 Nm (542 lb-ft).
Customers may request additional modifications. For instance, the Dodge Challenger SRT8 OCTSRT8-700 pictured below features the same V8 HEMI engine, but the client wanted even more power; so, the displacement was increased to 7.0 liters and the engine now outputs 720 PS (529 kW) and 875 Nm (645 lb-ft) of torque. Also worth mentioning is that O.CT Tuning will also provide a compressor upgrade for the Dodge Ram 1500 and its V8 5.7-liter HEMI engine. All good news!
