Hennessey's Dodge Challenger Hellcat cranks out 1,032 hp

Enthusiasts know the Dodge Challenger Hellcat produces 707 horsepower. It's one of the modern muscle-car era's iconic numbers. But for some, that's not enough. Enter Hennessey Performance. The Texas tuners loaded the Hellcat with a twin-turbocharger that works with Dodge's supercharger to boost output to 1,032 hp and 987 pound-feet of torque. Yes, that's an engine dyno rating, not at the rear wheels, but still! It's a little more complicated than a bolt-on booster. Called the HPE1000, the turbo kit has stainless steel headers and down pipes, billet aluminum compressor wheels, and a high-flow air system. There's also an an improved fuel pump, and the engine and chassis are specially calibrated. You also get numbered plaques signed by John Hennessey himself and the engine tech who builds your mill. All of this helps get your Hellcat to 60 miles per hour in 2.7 seconds, and it can do the quarter mile in 9.9 seconds at 142 mph. The Hellcat and it's 6.2-liter blown Hemi V8 are not for the faint of heart. Hennessey makes this Dodge downright demonic.

Speedkore AWD twin-turbo Carbon Charger, best birthday gift ever

The backstory the Speedkore Performance AWD twin-turbo Carbon Charger teased a couple of weeks ago might be cooler than the car itself. Alan Palermo commissioned the carbon-fiber-bodied Dodge Demon Speedkore brought to SEMA last year, the one that supplanted the 6.2-liter Hellcat V8's supercharger with twin 6875 Precision Billet T4 turbos. That blasted the Demon's usual 840 horsepower up to 1,400 hp at the flywheel, 1,203 hp at the rear tires, good for an 8.77-second quarter-mile time at 162 miles per hour. Palermo's older brother remarked, "He liked the car but was more of a four-door guy," so Alan commissioned the AWD Carbon Charger as a 65th birthday gift for his sibling. Speedkore worked with Magnaflow on the sedan, starting with a 2019 Charger Pursuit as a base. The Wisconsin tuner secured a 2020 widebody Charger from Dodge, then 3D-scanned the bodywork to create the molds reproducing most of the sheetmetal in pre-preg carbon fiber. The hood, bumpers, fenders, rockers, rear spoiler, and rear diffuser are all fashioned from the lightweight stuff.  Beyond those Precision turbos laid in by Gearhead Fabrications, Speedkore installed a custom upper plenum, Boost Leash C02 progressive boost controller, custom Thitek heads, a Fore Innovations triple-pump fuel system feeding Injector Dynamics 1,700-cc injectors, and custom HP Tuners engine software calibration. Test results showed 1,525 hp at the crank when running 26 pounds of boost.  Hellraiser Performance engineered a new transmission working an FTI torque converter at one end and a carbon fiber driveshaft at the other. Instead of fortifying an off-the-shelf AWD system, Traction Products supplied a custom transfer case machined from billet shunting power to a set of Bogart Competition Series wheels wearing Mickey Thompson ET street rubber.  Speedkore fitted last year's Demon with a front-exit twin exhaust, with a single opening on each front fender, and left the rear bumper cutouts for the traditional exhaust empty. With the Carbon Charger sedan more of a family guy, Magnaflow sorted out a quad-pipe front-exit exhaust with two openings on each front fender, and ran a three-inch stainless steel Competition Series exhaust to the rear. The driver can switch between the two, the latter version providing a "moderate interior sound."  The folks at Speedkore say they'll keep tweaking the Carbon Charger after the show to get it right for the senior Palermo. We say, "Happy birthday, sir. Enjoy."

The 2018 Dodge Demon sounds like nothing else on the road

The Dodge Demon seems to have a torque problem, if making too much to easily contain can be considered a problem. In order to keep all that twist under control, the Demon has a new torque reserve launch system that works all sorts of engineering black magic to build boost without overloading the rear tires and brakes. That system, combined with the sticky Nittos and the fancy new suspension, should lead to some pretty spectacular 60-foot and 1/4-mile times. The way the system works is relatively straightforward. A bypass valve on the supercharger closes, "prefilling" the blower. In order to balance revs and torque, the computer can adjust fuel flow and spark on individual cylinders. The torque reserve kicks in when Launch Mode is initiated and the engine is turning at least 1,000 rpm. The goal is to reach peak boost quicker while efficiently putting down power. The side effect is a distinct exhaust note, which Dodge admits may make it seem like the Demon is broken. That seems to be the root of the "If you know, you know" tagline that the automaker has been using since the first teaser. Those interested can even download a ringtone, which might make it seem like you have a blown-out speaker on your phone. You can get a brief taste in the latest teaser video. In addition to the new info on the Launch Mode, Dodge released a couple of new teaser images. We briefly glimpsed one of these last week. It's a shot of the Demon's performance pages. The number 757 has appeared before, and all the talk of torque leads us to conclude that this is the Demon's torque output. The number 815 was seen in a separate teaser (shown below), which we feel may be the horsepower rating. If those numbers are correct, that would mean an increase of 108 horsepower and 107 lb-ft of torque, totally reasonable numbers given all the Demon's modifications. The license plate photo is another equation or code. This one, 3.9+221=405, is just as cryptic as the others.
