Mopar Reveals 1,000-HP 426 Crate Hemi ‘Hellephant’ Engine

Mopar has revealed a brand-new HEMI-engine-powered “Hellephant” 426 Supercharged Mopar Crate engine, which turns the crank at 1,000 hp and 950 lb.-ft. of torque. The announcement also included the unveiling of the ’68 Dodge “Super Charger” concept.

Mopar has revealed a brand-new HEMI-engine-powered “Hellephant” 426 Supercharged Mopar Crate engine, which turns the crank at 1,000 hp and 950 lb.-ft. of torque. The announcement also included the unveiling of the ’68 Dodge “Super Charger” concept, which highlights the Hellephant 426 Supercharged Crate HEMI engine assembly and kit.

 

The Hellephant engine hits the 1,000 hp mark via bulked-up displacement, with 4˝ of stroke and bore specs at 4.125˝. An improved supercharger with a high-efficiency rotor is mounted on the all-aluminum block, which provides weight savings to keep the Hellephant light. The all-aluminum block, used in Mopar Dodge Challenger Drag Pak race vehicles, was configured for the street in close collaboration with Mopar and engineers from the motorsports world.

The engine and kit’s Hellephant logo and name call out the 426 HEMI engine, first introduced in ’64 and nicknamed the “elephant” engine for its power and size, as well as the 707 hp Mopar “Hellcrate” engine kit, revealed at last year’s 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 hp 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-’76 street and off-road vehicles.

Additional Hellephant 426 Supercharged Mopar Crate HEMI engine features include valve covers imported from the Dodge Challenger SRT Hellcat Redeye and valvetrain, valves, locks and retainers pulled from the Dodge Challenger SRT Demon. The engine build includes a special high-lift cam and 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.

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 Hellephant 426 Supercharged Mopar Crate HEMI engine assembly and kit will be available in the first quarter of 2019.
