Mopar has unveiled a brand-new Hemi-engine, the “Hellephant” 426 supercharged Mopar Crate Hemi, boasting 1,000 horsepower and 950 lb.-ft. of torque. The new engine, a Mopar-first for a 1,000-horsepower crate engine kit offered by an Original Equipment Manufacturer (OEM), was unveiled Tuesday at the 2018 SEMA Show.
“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 “Hellephant” engine hits the 1,000 horsepower mark via bulked-up displacement, with 4.0 inches of stroke and bore specs at 4.125 inches. An improved supercharger with a high-efficiency rotor is mounted on the all-aluminum block, which provides huge weight savings to keep the “Hellephant” light. The all-aluminum 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.
The engine and kit’s distinctive “Hellephant” logo provides a nod to the Mopar brand’s past and present. The logo and name call out the legendary 426 Hemi engine, first introduced in 1964 and nicknamed the “elephant” engine for its power and size, as well as the 707-horsepower Mopar “Hellcrate” Engine Kit, revealed last year at the 2017 SEMA Show.
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.
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 Challenger SRT Demon. The engine build includes a special high-lift cam, as well as custom-forged pistons.
The “Hellephant” 426 Supercharged Mopar Crate Hemi Engine 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 1,000 horsepower and 950 lb.-ft. torque.
As with the “Hellcrate” engine, Mopar will also offer an essential Front End Accessory Drive (FEAD) Kit, which includes an alternator, power-steering pump, belts, pulleys and more, and is among additional engine accessory hardware components available to assist in installing the “Hellephant.” The kit ships in unique packaging, featuring the “Hellephant” logo and includes in-depth information sheets with helpful installation tips and requirements.
The “Hellephant” 426 Supercharged Mopar Crate HEMI engine assembly and kit will be available in the first quarter of 2019. For more information, visit www.cratehemi.com.
