Holy Hellephant!

The Mopar brand stampeded into SEMA Show with a new HEMI-engine-powered beast called the Hellephant. The 426 Supercharged Mopar Crate HEMI engine turns the crank at a mammoth 1,000 horsepower and 950 lb.-ft. of torque.

The company also revealed its 1968 Dodge Super Charger concept, which featured the Hellephant crate HEMI engine assembly and kit. 

“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 for Mopar and passenger car brands for 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 4 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, according to Mopar. 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, according to the company. 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 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 crate engine assembly can be paired with the Mopar Hellephant 426 Supercharged Mopar Crate HEMI Engine Kit for relatively simple plug-and-play by experienced installers, according to Mopar. 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.

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 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.
