Hennessey 2013 Jeep Grand Cherokee SRT8 HPE650 kit with 485kW (video)

Hennessey Performance in the US has come up with a tuning package for the 2013 Jeep Grand Cherokee SRT8 V8 monster, called the HPE650 kit. The muscle SUV is able to cover the quarter mile in just 12.6 seconds.

Featuring a naturally aspirated 6.4-litre HEMI V8 in standard form, the SRT8 is able to run the quarter mile in 13.4 seconds, as tested by PerformanceDrive earlier this year. Thanks to the addition of a supercharger, the boosted SUV is given supercar powers.

The HPE650 kit includes a TVS2300 supercharger, ported cylinder heads, a custom air intake, a stainless steel exhaust, an uprated fuel system, and an engine computer retune. This gives the anabolic SUV a very meaty 485kW – up considerably from the standard 344kW rating.

Giving the SUV further exclusivity, the Hennessey pack comes with bespoke floor mats, a special build number plaque and engine cover, and a three-year/57,960km (36,000 miles) warranty. A revised interior is optional if the customer wishes, as well as a bigger tyre and alloy wheel package.

In its standard form, the SRT8 is an awesome beast. With this supercharged pack it must be an absolute animal.
