If you want to go hellaciously fast, you need a Hellcat engine.
Dodge's Hellcat engine made its first splash by giving the Challenger an immense 707 horsepower to shred rubber with. Inevitably, some Dodge Challenger Hellcat cars were crashed, and the engines were bought and transferred into other cars. Now, the Hellcat engine is available as a crate engine so anyone with the money can buy a brand new 6.2-liter Supercharged V8 engine and put it in anything they damn well please. If you're thinking of going down that route rather than picking one up from a breaker's yard, it costs around $16,000 and is designed to work with Tremec T56 Magnum transmissions, although there is a controller available to match it to other gearboxes.
That's a huge engine and a lot of transmission to fit into a car that wasn't designed with a supercharged V8 in mind. That means it takes a creative mind, a lot of technical skill, and, in some cases, a complete lack of fear to drive the resulting car. These are the most hellacious of Hellcat swapped cars we have seen over the past couple of years.
Dubbed "HellKitty," the now bright orange Hellcat swapped 1999 Mazda Miata made quite a splash across social media when it first emerged. Somehow, YouTuber Stephen Crapps managed to squeeze the monstrous engine into the tiny Miata's engine bay as well as install a six-speed Tremec manual transmission. For practical fun, he linked the transmission to a Ford 8.8-inch rear-end with a welded differential from a Mustang Cobra. Without further modifications, HellKitty would be a barely guided missile, so Crapps also fitted a modified suspension and Wilwood brakes to keep the car in some sort of control.
Back in the day, when Mopar wasn't doing much in the way of muscle cars, the V8-powered Dodge Dakota was the best option for big engine freaks if they couldn't afford or find an SRT-10 Ram 1500. In fact, people are still racing second-generation Dakota trucks today, including one Greg Snider. Over time, he built up the original 1998 Dakota's V8 engine and added a supercharger, but, when it broke the transmission, Snider opted to go down the Hellcat route. Power from the engine is sent to the back via a Tick Performance Stage-3 T-56 manual transmission designed for the Dodge Viper but, surprisingly, much of the Dakota's suspension is still stock.
This Hellcat Swapped 1969 Dodge Charger is the perfect example of the old meeting the new. However, no non-like for like engine swap is straightforward, and this one required some serious fabrication. It was Cleveland Power And Performance that married together this dreamboat of a muscle car, and the first hurdle was sourcing a 1969 Charger as the Dukes Of Hazzard production crew had crashed most of them. In reality, the company married the Charger's bodywork to a cut and shaved 2016 Hellcat chassis, but we're still filing this one as an engine swap for the ages.
It was only a matter of time before someone decided to transform a perfectly good Toyota Prius into a 1000-horsepower Hellcat-powered drag monster. American Racing Headers of Long Island, New York, took it on as a project, and it'll comfortably run a nine-second quarter-mile time. Not only that, but the air-conditioning in the PriuSRT8 works as well. According to the owner, it cost $150,000 to build and isn't finished. He believes the Prius has an eight-second quarter-mile time on the horizon. And, those aren't words we ever expected to publish.
While the 1969 Dodge Charger used some serious engineering and fabrication chops to make use of a modern Hellcat car's chassis as the basis of the build, Roadkill hosts David Freiburger and Mike Finnegan don't tend to have that kind of patience. They scored the shell of a 1968 Charger from a dump of a desert town in Southern California in exchange for a set of big-block Mopar aluminum cylinder heads. They promptly stuck a 440 big-block engine from a Motorhome in the car, but that wasn't enough. A hardcore racing suspension system was added begore Freiburger and Finnegan then decided it needed a 707-hp Hellcat engine so they could go drag racing. With a little help from Diversified Creations, it now puts down a crazy 975 horses.
If there's an automotive wrong from the last century that can be fixed with almost any V8 engine, it's the Plymouth Prowler. The wild-looking production homage to 1930s hot rods somehow found itself with a V6 engine from the Dodge Intrepid under the hood. You might say a Hellcat engine is overkill, but we say its justice. The team at Brand New Muscle Car is mainly known for Eleanor Mustang recreations, but the company isn't afraid of wild jobs like this. The front end needed some substantial re-engineering and a new cooling system, the famously fragile rear axle required something more substantial, and transferring the power to the back wheels is a two-speed Powerglide automatic transmission.
When House Of Mouse Racing decided to Hellcat swap a 1968 Coronet cop car, it was a last-minute decision as the engine was due to go into a 1970 Baracuda. The 'Cuda would have taken too long to build, though, and the Hot Rod Power Tour 2019 was just months away. So, House Of Mouse threw the engine and the front suspension into the Coronet shell it already had available. The tuners then printed up special Hot Rod tickets for the event to "cite" people to raise money for Shop with a Cop, so not only is it an awesome off the cuff project, but it was put to great use as well.
Swapping a Hellcat into a Jeep is something a few people and companies have perfected now, but the most insane example is dubbed "Inferno". Built by Exotic Custom Motorsports, Inferno is a Hellcat-powered Jeep Wrangler modified to have a 6x6 drivetrain. The base vehicle is a 2016 Jeep Wrangler Rubicon 75th Anniversary Hard Rock Edition, but the body has been stretched and become a truck. Inferno has a true 6x6 drivetrain with three live axles and three Ford nine-inch-based 4.10 differentials that can be locked. That means you can lock the rear two axles and light up all four tires for hilarious hijinks and big traffic tickets.
Having six wheels is all well and good, but, if you go off-roading, you'll want a shorter wheelbase 99.9 percent of the time. Dakota Customs in Rapid City, South Dakota, offers a kit for $23,000 to swap a JK generation Jeep Wrangler or will do it for you for $56,000. The company's vehicle uses the ZF 8HP90 eight-speed automatic transmission and has paddle shifters behind the wheel for manual cog swapping. For serious off-roading, it also features RCV axle shafts, a 4-inch Synergy lift, Fox remote-reservoir shocks, and a set of 37-inch all-terrain tires. When Dakota customs sold it, buyers paid $139,995 to drive it away.
