    hennessey jeep srt8 600

    The 2013 Jeep Grand Cherokee SRT8 is an amazing piece of automotive machinery but the Hennessey Performance HPE650 package takes the brawny Jeep super-sport ute to a whole new level – with an incredible output of 650 horsepower allowing a 0-60 time of just 3.9 seconds.

    The HPE650 Jeep Grand Cherokee SRT8 package begins with the standard 392 cubic inch Hemi V8 and adds ported factory cylinder heads, stainless steel long tube headers, high flow catalytic convertors, an upgraded fuel system, a TVS2300 Supercharger System, an HPE Air Induction System and an HPE/Arrington engine tune to increase the output from 470 horsepower to 650 horsepower.  When coupled to the standard 5-speed automatic transmission (this is based on a 2013 model year vehicle – not the 2014 SRT Jeep with the new 8-speed unit) and the standard full time four wheel drive system, this ultra high performance Jeep can rip from  a stop to 60 miles per hour in just 3.9 seconds.  The HPE650 Jeep SRT8 will also dash down the quarter mile in just 12.6 seconds with a trap speed of 110 miles per hour.

    To show off the HPE650 package on the 2013 Jeep Grand Cherokee SRT8, the folks at Hennessey have put together a pair of videos with one showing the 650 horsepower SUV trying to climb off of the dyno and a longer piece highlighting the features of this super SUV before an in-car ride down the quarter mile.  At the end of the video, we get to see the quarter mile dash once again – this time from a camera behind the vehicle that really gives us a great chance to hear the blown Hemi scream down the drag strip.

    When watching these two videos, make sure to have your speakers cranked up so that you can hear the 392 cubic inch Hemi making 650 horsepower with 7-8 pounds of supercharger boost.
