Hennessey to turn Jeep's insanely powerful Trackhawk into a 1000 hp monster

Article by Christian A., on September 25, 2017

Hennessey will be dishing out another HPE1000 performance package this time exclusively for Jeep’s Grand Cherokee Trackhawk SUV. Think HPE’s 1000hp Exorcist (or something like that) that will amplify the SUV’s powerful performance. To that end, Hennessey will provide the Trackhawk’s already potent 6.2liter Hellcat V8 Hemi engine with an added boost of up to 14 psi coming from its 4.5 liter supercharger.

Not only this. The full-size SUV will also come equipped with a high flow air induction system, an upgraded fuel pump, a high-flow supercharger bypass valve, some upgraded fuel injectors and new stainless steel long tube headers. All of these will come with the necessary gaskets and fluids.

The enhanced ECU will likely increase its power to 1,012 hp at 6,500 rounds per minute and 969 pound feet of torque at 4,200 rpm. The Trackhawk could go from a zero to 60 miles per hour (96km/h) in 2.8 seconds before hitting the quarter mile in about 10.5 seconds or less at 133 miles per hour (214km/h). You will need Shell V-Power 93 octane gasoline to run this machine including Pennzoil Ultra Platinum synthetic oil for maintenance and filter change.

Hennessey will provide a before and after dyno graph report in order for you to see the power and amount of torque measured at the rear wheels. There are no prices released yet but considering Hennessey’s track record, we might see some Trackhawks arriving in Texas following this report.

It is rather interesting to find out how the SUV’s AWD system could actually manage the additional 305hp after the boost. The Jeep Grand Cherokee Trackhawk as we know currently has 707hp under its hood. Similarly, the HPE1000 will come with a one-year warranty or up to 12,000-miles coverage.

Hennessey will also be including 2 plaques exclusively for the package, one with a serial number which is found at the engine bay with the technician’s signature while the other plate will be signed by Mr. John Hennessey himself which you can see along the interior. Speaking of which, the interior will also feature the special “powered by Hennessey” premium floor mats to complete the look. The exterior part of the SUV will likewise receive the same “powered by Hennessey” badges along the side and rear sections.

According to HPE, the acceleration performance figures after the upgrade are based on the ideal driving conditions as controlled by an experienced driver using a prepped 1/4-mile dragstrip on drag radials. The 1000hp on the other hand is the estimated power ratings at the engine only while the exact power will be drawn at the rear wheels prior to the upgrade and after the installation and tuning are finally complete.
