O.CT Tuning has impressed us once again with a new program for the 2014 Dodge Challenger SRT8. Not that the Challenger needs it seeing as a standard model already packs a 6.4-liter, V-8, HEMI engine that produces 470 horsepower and 470 pound-feet of torque. But O.CT Tuning's not impressed with those numbers, which is why the German tuner took it upon itself to give the American muscle car->ke507 its new OCTSRT-700 program.

The program's name pretty much says it all. This program means serious business, the likes of which we rarely see on a Challenger SRT8. For one, those stock HEMIs were deemed somewhat inadequate, hence the company's decision to increase its displacement to an incredible 7.0 liters. O.CT Tuning then slapped on a compressor to the larger-displacement engine, resulting in an incredible power upgrade of 720 horsepower and 645 pound-feet of torque.

I'm no math genius or anything, but I do know that 470 is a long ways away from 720 -- that's an incredible difference of 250 horsepower -- so excuse me for being a little tickled by the added output given to one of America's finest pony cars.

This program is one of the most powerful we've seen on the Challenger SRT8. The fact that a German tuner did it speaks to the Challenger's->ke249 appeal as a global muscle machine.

Dodge Challenger SRT8 By O.CT Tuning in detail

Some people aren't going to be comfortable behind the wheel of a Challenger with that much power. That's understandable, especially if they don't know how to tame all those horses.

That's not a problem for O.CT Tuning because it has something a little more subdued. The company doesn't increase the displacement of the engine, opting instead to install a compressor kit and a charge air cooler system to go with a software optimization.

The result's aren't as impressive as 720 horsepower and 645 pound-feet of torque, but with an improved output of 564 horsepower and 542 pound-feet of torque, that's more than enough to justify this hefty performance increase.

All that power under the Challenger's hood means nothing if it doesn't have the requisite certificates to make them road legal. Fortunately, O.CT Tuning's supercharger conversions come with a MOT / DTC certificate, ensuring that its massive program can be enjoyed by drives all over Europe.
