The Jeep Grand Cherokee Trackhawk is, as metal band Pantera might put it, a vulgar display of power.
An astonishingly fast brute, the Trackhawk will hit 100km/h in a claimed 3.7 seconds, thanks to 522kW/868Nm from its 6.2-litre supercharged V8. It also weighs 2399kg.
But what usually happens when an American muscle car is fresh onto the market? That’s right, John Hennessey gets a hold of it and turns it up to 11. Or, in the case of the Trackhawk, 10.5. Seconds.
It’ll also hit 100km/h in just under 3 seconds, which rivals the sprint claimed by the Porsche 911 GT2 RS.
How, you ask? 746kW for a start, and a torque figure with four digits, 1314Nm.
It produces 14psi, and is helped along by a few other peripheral parts in the engine bay.
High-flow injectors, induction, and fuel pump mean everything the engine needs to go fast is… well, flowing. An engine management re-tune keeps it all in check, while some dyno testing and calibration ensures it worked.
Sadly, Hennessey being US-based means this kit probably won’t see Aussie roads, but do let us know if you manage 1000hp from your own Trackhawk. We’d be very interested to know.
