The motto at Hennessey Performance must be something along the lines of: "There's no such thing as too much power." From Vipers and Corvettes to Raptors and the Venom GT, Hennessey will slap on turbos, superchargers, or whatever else you can afford to give you more power. The latest creation? A Dodge Challenger SRT Hellcat with 1,032 horsepower.
We're pretty sure no one will argue that Hellcats are lacking in the power department, but that didn't stop Hennessey from working up a turbo upgrade kit for those feeling the need for more speed. Dubbed the HPE1000 Twin Turbo package, it adds a twin turbo system that includes twin ball-bearing turbochargers, a high-flow air-to-water intercooler system, stainless steel turbo headers and downpipes, dual turbo wastegates, turbo inlet tubing with dual blow-off valves, upgraded high-flow fuel injectors, an upgraded fuel pump and fuel system, and a long list of other items to make sure the car won't up when all that power is used. Total pounds per square inch of boost isn't available, but all this works in conjunction with the factory supercharger that produces 15 psi of boost of its own.
This all adds up to 1,032 horsepower at 6,500 rpm and 987 pound-feet of torque at 4,200 rpm. Performance is mind bending for a vehicle weighing more than two tons, with 0-60 mph taking just 2.7 seconds and the quarter mile flying by in 9.9 seconds at 142 mph.
Don't need that much power but still want more than the factory setup? The HPE800 and HPE850 packages are still available, and they up the output to 800 and 850 horsepower, respectively.
All packages come with a one-year, 12,000-mile limited warranty.
Pricing isn't listed, but, as many enthusiasts know, a quality build isn't cheap.
Is this kind of power necessary? Absolutely not. Is it ridiculous? Without question. But you bet your butt we are glad it exists.
