All hail the Hellephant, Mopar's 1,000-horsepower crate engine

It's shocking to say this, but the all-powerful Dodge Demon looks weak now that Mopar has unleashed the Hellephant. This crate motor makes 1,000 horsepower and 950 pound-feet of torque, and its name is a combination of the nickname for the old 426-cubic-inch Hemi V8 and, obviously, the Hellcat. This monster is a 426-cubic-inch version of the current third-generation Hemi V8 topped by a supercharger similar to what the Hellcat line packs. Everything is cranked up to — or perhaps, past — 11. The engine block is made of aluminum and weighs 100 pounds less than the equivalent iron block. All of the internals are forged. The stroke and bore have been increased. The supercharger produces 15 pounds of boost and displaces 3 liters; more than the 2.7-liter blower on the Demon and the 2.4-liter blower on the Hellcat. And as big and powerful as it is, it will still rev to 7,000 rpm. It's a thoroughly monstrous motor, but shockingly, it won't be that difficult to live with. For one thing, Mopar will offer a complete kit to get the engine up and running, including an engine computer, wiring harness and drive-by-wire throttle. It also runs on 93-octane pump gas. That's especially amazing considering the Demon engine "only" makes 840 horsepower, and that's on race gas with 100+ octane fuel. It also has us wondering what the Hellephant could make on racing fuel. The Mopar folks did say that there's room to add more power. Pricing wasn't announced for the Hellephant engine. The Hellcat crate engine retails at $19,350 directly from Mopar, so it's safe to assume that the Hellephant will go for more. The installation kit with the computer and harness will be an extra charge of likely over $2,000, based on the Hellcat kit. The engine and the kit will be available in the first quarter of 2019.

Dodge Charger Hellcat makes 1,032 hp with Hennessey help

Sometimes you just want four doors. Earlier this week we brought you Hennessey's riff on the Dodge Challenger Hellcat. Now comes the Charger. Much like its two-door sibling, the Charger gets boosted to as much as 1,032 hp and 987 lb-ft of torque (at the crank) thanks to the addition of a twin-turbocharging setup that works with the factory supercharger. The turbo headers and downpipes are stainless steel, and there is a high-flow air-to-water intercooler and dual-turbo waste gates. Hennessey also beefs up the fuel injectors, fuel pump, and the rest of the fuel system. The engine management system and chassis are recalibrated to accommodate all of this. You also get numbered plaques signed by John Hennessey, the boss of the Texas tuning outfit, and the technician who does your build. Hennessey's additions result in zero-to-60 mph sprints in 2.7 seconds, and the big sedan can run the quarter mile in 9.9 seconds at 142 mph. Like the Challenger, the Charger has the same disclaimer: the lofty horsepower figure comes from an engine dyno, and it will be a 15-to 20-percent lower at the rear wheels.

Dodge Challenger ADR prototypes spied with massive rubber

In an effort to give the Dodge Challenger one last hurrah before making the switch to the Giorgio platform in 2018, Automotive News reports that the automaker will come out with the Challenger ADR. The ADR, which stands for American Drag Racer, is expected to be a wide-body, Hellcat-powered variant that is closely based off of the current model. The report seems to have merit, as photographers have captured Challenger prototypes testing with massive tires. The prototypes look extremely similar to the current Challenger SRT Hellcat with the same hood scoop, front fascia design, rear spoiler construction, and rear end. The white and purple vehicles, though, are wearing extremely wide tires. The extra-wide rubber on the prototypes appear to have a similar tread design as the ones found on the Dodge Viper ACR, which features the grippy Kumho Ecsta V720. While the ACR wears 295 mm tires at the front, the car's rear tires are massive at 355 mm. The tires found on the prototype don't appear to be as large as the ones found on the ACR, but are expected to be larger than the current Challenger SRT Hellcat's, which are Pirelli P Zero Neros measuring 275 mm at all four corners. The Challenger ADR, with its wider, stickier tires is expected to cater to drivers that are looking to put all of the supercharged 6.2-liter V8's power to the ground. The rear-wheel-drive ADR is expected to come with a wide-body kit, which is missing from the prototypes. The Hellcat-powered, wide-body Challenger ADR is expected to make an appearance later in 2017, with an all-wheel-drive model (sans Hellcat engine) known as the GT AWD following closely thereafter.
