Swiss Tuner Taps into ECU to Boost Trackhawk’s Strength
OC.T Tuning pushes output of Trackhawk monster’s supercharged V8 to 865 horses, and that’s only with the first stage tune.
When you think of Switzerland, what comes to mind? Chocolate? Watches? Multi-purpose tools? You wouldn’t be wrong to think of any of those things, as the Swiss are good at what they do, and then some.
Did you know they also tune Jeeps, though? OC.T Tuning in the Swiss-Austrian border town of Widnau, Switzerland got their hands on the most powerful Jeep around, the Grand Cherokee Trackhawk, and South African publication Car Magazine has the story on what OC.T did with the high-performance luxury SUV.
According to Car Magazine, OC.T tapped into the Trackhawk’s ECU to squeeze even more power from the SUV’s supercharged 6.2-liter V8. The result is an “unmatched dynamic performance” never before experienced behind the wheel of the high-speed Jeep.
How much performance? The Trackhawk already made 707 horsepower and 645 lb-ft of torque from the assembly line. OC.T’s version, based off of the Euro-market model, amps the power up to 819 horses and 700 lb-ft of tire-twisting madness. Of course, that’s only the first stage.
OC.T also has a second stage in the works for the Trackhawk, which the tuner says includes a new supercharger pulley kit and a software refresh for the eight-speed automatic. The expected output of this upgrade is 865 horses and 738 lb-ft of strip-destroying ferocity.
While the Swiss have fun with their Trackhawk upgrades from OC.T, there’s no word on whether or not we here in the United States will have access to their madness. Of course, we don’t have to fret too much about not getting enough from the quarter-mile monster. As we reported a few months ago, Hennessey Performance has the HPE1200 supercharger upgrade to bring the boost.
The record-setting upgrade for the Trackhawk includes a 4.5-liter supercharger plus all the necessary bits to handle all of that air being forced through the big V8. The resulting power bests OC.T’s ECU tune, too: 1,003 horses and 892 lb-ft of torque at the wheels, a zero to 60 time of 2.3 seconds, and a top speed of over 200 mph. We’re definitely not hurting from a lack of Swiss tuning here.
