"Nothing beats a blown Hemi."
You’ve got to hand it to Hennessey Performance, as it certainly knows how to take things to the next level. Aside from gems like the Venom GT and tuned Mustangs and Raptors, the Texas-based company has now set its sights on the Jeep Grand Cherokee SRT8. In stock form, the hi-po Jeep is good for 470 horsepower thanks to its 392 cu in 6.4 Hemi V8. However, Hennessey upgraded that engine with a supercharger package that, along with a few other add-ons, increases total output to an outright bonkers 650 hp.
Already having been tested it on the dyno, John Hennessey himself can be seen here taking his GC SRT8 out for a 1/4-mile test run. With a 0-60 mph time of just 3.9 seconds and an all-in price of under $90,000, this tuned performance SUV is a real bargain when compared to something like the Porsche Cayenne.
