Quarter-mile King Posted by Auto Advisor, April 26, 2018
If you thought the Dodge Demon's supercharged V8 was the most powerful American motor you could buy today, think again. At The SEMA Show, Dodge unveiled the "Hellephant" – a 1,000-horsepower (746kw) plug-and-play crate engine for the street.
"Our enthusiasts crave power and performance, and our new 'Hellephant' Mopar Crate HEMI engine and kit deliver huge horsepower and torque in a plug-and-play package that is unique in the industry," said Steve Beahm, Head of Parts & Service (Mopar) and Passenger Car Brands, FCA - North America. "The 1968 Dodge Charger is one of the hottest classic cars, which is why we decided to use it as a starting point for the 'Super Charger' Concept. It's an amazing vehicle and a great showcase for our 'Hellephant' engine."
The "Hellephant" engine hits the magical 1,000 horsepower mark via bulked-up displacement, with 101.6mm of stroke and bore specs at 104.78mm. An improved supercharger with a high-efficiency rotor is mounted on the all-aluminium block, which provides huge weight savings to keep the “Hellephant” light.
The all-aluminium block, used in Mopar Dodge Challenger Drag Pak race vehicles that dominated the 2018 NHRA Factory Stock Showdown class, was configured for the street in close collaboration with Mopar and engineers from the motorsports world. Additional features of the “Hellephant” 426 Supercharged Mopar Crate HEMI engine include valve covers imported from the Dodge Challenger SRT Hellcat Redeye and valve train, valves, locks and retainers pulled from the Dodge Demon. The engine build includes a special high-lift cam, as well as custom-forged pistons.
The complete engine assembly includes a water pump, flywheel, front sump oil pan, supercharger with throttle body, fuel injectors and coil packs. The first-ever 1,000 horsepower crate engine assembly offered by an OEM can be paired with the Mopar "Hellephant" 426 Supercharged Mopar Crate HEMI Engine Kit for relatively simple plug-and-play by experienced installers. The engine assembly and kit are designed for installation on pre-1976 street and off-road vehicles.
Dropping in the "Hellephant" is almost turnkey with the "Hellephant" 426 Supercharged Mopar Crate HEMI Engine Kit. The kit includes a powertrain control module (PCM), power distribution center, engine wiring harness, chassis harness, accelerator pedal, ground jumper, oxygen sensors, charge air temperature sensors, fuel pump control module and cam bus interface device. The PCM is unlocked and tuned to pump out 745kw and 1290nm torque.
And to showcase the new supercharged 426 HEMI "Hellephant", they dropped it into '68 Dodge Charger...naturally. The muscle car, called the Super Charger Concept, sees the 746kw motor paired with a T-6060 manual six-speed Hellcat transmission; and features massive six-piston Brembo brakes behind 20-inch and 21-inch Hellcat wheels.
The custom “De Grigio” Grey Metallic classic 1968 Dodge Charger, which is marking its 50th anniversary in 2018, feeds the “Hellephant” fresh air through a supersized hood scoop modelled on that of the SRT Demon. The hood features fibreglass construction on the outside with inner-steel construction inside carried over from the original vehicle. The 1968 Charger’s pop-up headlamp design is tweaked to plant Hellcat headlamps permanently behind the grill. The original’s door handles and drip rails are shaved away, creating a clean, streamlined appearance. Front door vent windows are removed and replaced with a one-piece side glass. The 1971 Duster mirrors add a more modern appearance.
The interior has also been thoroughly refreshed, borrowing tech from the Dodge Challenger Hellcat and the Dodge Viper. Inside, door panels and interior trim are Satin Black with the unique "Hellephant" milled medallion applied on the upper door panels. The Dodge Viper steering wheel also carries the "Hellephant" medallion at its center. The instrument panel insert is "De Grigio" Grey Metallic body color and the dash is customized with a full array of Mopar gauges.
The “Hellephant” 426 Supercharged Mopar Crate HEMI Engine will be available in early 2019, with more information available at www.cratehemi.com.
