Yahoo Autos Electrophonic Tonic: See and Hear Mopar’s New 1000-HP 426 Hemi Crate Engine
Of all the mighty V-8 engines to earn their stripes on the streets and strips of America, few possess more mystique than the Chrysler 426 Hemi. Nicknamed the Elephant for its massive size, weight, and output figures, the engine's legend has long outstretched its reality. The latest chapter entry in the book of Hemi is the new Mopar Hellephant Crate engine. It was released today at the 2018 SEMA show under the hood of the 1968 Dodge Super Charger concept, and we figured an engine of such legendary stature deserved its own post.
The first 1000-hp crate engine to be offered by an automaker, the Mopar Hellephant is an obvious evolution of the breed, a fuel-injected, electronically controlled, supercharged melding of displacement and modern technology that produces 1000 horsepower and 950 lb-ft at the crank. Built on an aluminum block borrowed from the Mopar Dodge Challenger Scat Pack vehicles, it features extensive webbing and gusseting for weight savings-as much as 100 pounds compared with a Hellcat block, says Chrysler-and a rigid core. Assembled with 4.0-inch stroke and a 4.13-inch bore, it inhales via a voluminous 3.0-liter twin-screw supercharger running approximately 15 lb-ft of boost. (The Hellcat engine uses a 2.4-liter supercharger and the Hellcat Demon has a 2.7-liter supercharger.) The build includes custom-forged pistons and a special high-lift cam; the valvetrain and valves are borrowed from the Dodge Challenger SRT Demon, while the valve covers are pilfered from the Hellcat Redeye. Far from just a block and rotating assembly, the package includes a water pump, flywheel, front sump oil pan, supercharger with throttle body, fuel injectors, and coil packs.
Keeping tabs on the fury is the included powertrain control module (PCM), which works in unison with the 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. To the delight of tuners everywhere, Mopar says the PCM is unlocked but tuned to pump out 1000 horsepower and 950 lb-ft of torque from the factory.
As with the Hellcrate engine that debuted last year, Mopar will also offer an essential Front End Accessory Drive (FEAD) kit, which includes an alternator, power-steering pump, belts, and pulleys, and will offer several other components and parts individually.
Never one to miss a marketing opportunity, Mopar will ship each kit in Hellephant-logo packaging and will include information sheets with installation requirements and tips. Look for the Hellephant crate engine to come online for sale in the first quarter of 2019.
