According to the Texas tuning shop, Hennessey will build only 12 of its “HPE1000” Hellcat Chargers per year along with—you guessed it—12 similarly twin-turbocharged Hellcat Challengers too.
The Dodge duo’s 6.2-liter Hellcat V8s now ready 15 psi of boost and make their peak power at a roaring 6,500 rpm. Peak torque comes a tad sooner, 987 lb.-ft. at 4,200 rpm. The real benchmarks are speed however, and well… you can consider them met.
Slap on a pair of drag radial tires and the Charger and Challenger Hellcats will do zero to 60 mph in just 2.7 seconds and leave the quarter mile drag strip smoking with a pass of 9.9 seconds at 142 mph.
The new turbochargers complement a new air-to-water intercooler, stainless steel headers and downpipes, dual wastegates, inlet tubing and blow-off valves, fuel injectors, fuel pump, new air filter, and an ECU tune. You’ll also get some non-mechanical goodies too—signed plaques, “Powered by Hennessey” floor mats, and “Twin Turbo” badges to name a few.
Like ‘em? Just be careful you don’t blast-off into orbit.
