The now infamous Hellcat siblings produce an otherworldly 707 horsepower and 650 pound-feet of torque from a supercharged 6.2-liter V8. In a stock vehicle for under $70,000 that’s Costco-sized portions of power when someone really only “needs” a single serving. In Texas, however, where Hennessey has setup shop, meteoric power levels start far beyond stock figures.
That’s why the HPE1000 kit forces those poor rear tires to deal with 1032 horses and 987 lb-ft of torque. In my Hellcat tests, a full-bore launch meant I’d hook up somewhere in fourth gear. With over 1,000 horsepower, owners may be well into sixth gear before the tires link hands with the road surface. With a steady power inlet, though, Hennessey claims the power kit results in a 0-to-60 mph time of just 2.7 seconds (which happens to be quicker than McLaren’s 650S, for reference) and a quarter-mile time of 9.9 seconds at 142 mph.
The HPE1000 tune includes stainless steel headers and down pipes, billet aluminum compressor wheels, a high-flow air intake, new intercooler, improved fuel pump, re-tuned suspension and chassis, and the source of speed: a twin-turbocharger system.
It’s unclear if the stock Pirelli P Zero tires have been upgraded by Hennessey or not, but either way, you’ll roast them in a matter of a few weeks if your foot starts to feel heavy. Pricing hasn’t been announced, but if the 1,000-horsepower Camaro SS upgrade is any indicator, you’ll owe about $100,000 for your lofty power figure, including the price of the donor Hellcat.
With the introduction of the Charger-prepped kit, you can now choose to terrify one friend or three!
