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.

2018 Dodge Durango SRT Quick Spin | The modern hot-rod wagon

I love big, overpowered SUVs. Except for Mercedes-AMG, no one makes fast wagons anymore. Models like the BMW X5 M and the Porsche Cayenne Turbo S fill that niche, combining a powerful engine with copious amounts of room for cargo and passengers. These SUVs are too porky to handle well on a track and too big and wide to properly tackle a curvy backroad. But with a soft suspension and a 0-60 mph time of less than 5 seconds, they are perfect for cruising city streets and pulling away from unsuspecting Ford Mustangs and Chevy Camaros. That makes the 2018 Dodge Durango SRT perfect for the Woodward Dream Cruise. Dream Cruise is an annual car meet along Woodward Avenue, just northwest of Detroit. While literally any motorized vehicle is welcome, the street is mostly filled with American cars from the height of the domestic auto industry. For a late 20-something like myself, watching and partaking in the Dream Cruise fills me with a sense of nostalgia for a time and place that never existed for me, just like watching John Wayne in anything from "Stagecoach" to "True Grit" makes you long for horseback rides in the Old West. The Durango SRT, with a pushrod Hemi V8, 392 cubic-inch badging on the fenders and muscular styling, enhances the experience. Sure, it's not nearly as cool as Mopar stalwarts like the 1969 Plymouth Roadrunner or the 1970 Dodge Daytona, but it's filled with the same sense of purpose. Dip into the throttle and listen to that eight-cylinder chorus erupt with a sound that's wholly unique. Not even the pushrod V8s from GM snarl and crack like this 6.4-liter Hemi. It's the same sort of sound you'll hear from countless Dodge, Chrysler and Plymouth products during Dream Cruise. You don't need to go fast to get the full understanding of the Durango SRT's purpose. Ignore the SRT-tuned suspension and heavy steering. What you really want to do is open the SRT menu and adjust the custom settings. Set the engine and transmission in track mode and put everything else in the street setting. You'll get all the available power and straight-line performance combined with a nice, cushy ride. We're not sure what FCA has planned for the future. While the industry moves toward electrification and autonomous ride-sharing vehicles, the automaker is pouring money into vehicles like the Durango SRT, the Dodge Challenger SRT Demon and the Alfa Romeo Giulia Quadrifoglio. Future prospects look hazy.

Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:
