Dodge Supercharged Hellcat Engine

 Dodge Supercharged Hellcat Engine, Did you think the Supercharged 6.2L Hellcat Engine 707hp is dead and buried? Well, it may be officially dead, but it’s far from being buried.

 And no, we’re not referencing the countless examples that have hit the second-hand market and are looking for new homes.

 So, what are we talking about? Well, the 6.2L supercharged V8 has become a crate engine in Australia. Mopar’s local arm has announced a limited number of units available for order as of now.

 This assembly was first seen in the Jeep Grand Cherokee Trackhawk Down Under, pumping out 527 kilowatts (707 hp/717 ps) and 875 Nm (645 lb-ft) of torque.

 This unit steams out 361 kilowatts or 484 horsepower (491 ps) and 644 Nm (475 pound-foot) of torque. The supercharged unit features a water pump, fuel injectors, coil packs, an intake manifold with a throttle body, and a front sump oil pan.

 But how much would you have to cough out for the crate motors? That would be a cool AU$16,000 for the 392 HEMI V8 and nearly double for the supercharged lump, which is available at AU$29,000.

 The former pricing equals US$10,663 at the current exchange rates, and the latter translates to US$19,327. Remember that these prices exclude the Goods and Services Tax (GST), and you may also face some dealer markups in some cases.

 With Stellantis’ US brands looking to the future, which includes a significant amount of electrification, including for the latest Dodge Charger muscle car, these companies are no longer interested in V8 firepower.

 That’s certainly a pity, as most enthusiasts don’t care about traditional models that don’t feature a V8, which is why rides like the Ford Mustang still thrive.

You could opt for a used (barely driven) one, search the SH market for that perfect V8 motor, and undergo a heart transplant, but wouldn’t you rather have the option to buy a new V8-powered Charger instead?

Chris Cowland, Chrysler’s advanced and SRT powertrain director, recently came clean with the engineering secrets behind the 707-hp 6.2-liter Hellcat V-8.

 If you just stirred from suspended animation, this Dodge Challenger SRT engine is the most potent powerplant ever sold to customers for road use by any American manufacturer.

Revelation 1: While this Hemi is a cousin to 5.7-, 6.1-, and 6.4-liter Chrysler-built V-8 engines, the Hellcat is, for all intents, a new design sharing only basic architecture—such as a 103.9-mm bore—with its predecessors.

 More than 90 percent of the components (by value, not parts count) are new. The cast-iron block has thicker webs and more extensive cooling passages to support the added power and stress.

 The induction-hardened forged-steel crankshaft provides the desired 90.9-mm stroke. The powder-forged steel connecting rods have cracked bearing caps for more secure clamping.

 

Revelation 2: While the uninformed may deem an iron cylinder block yester-tech, Cowland insists it’s the ideal material for this application, given the intense loading.

 While a fresh aluminum design might save a few pounds, package dimensions would be more significant due to aluminum’s significantly lower stiffness.

 The hard-working, fast-spinning Hellcat crankshaft is well supported by the iron block’s deep side skirts and twenty bolts securing the five main-bearing caps. A meaty closed upper deck resists cylinder-bore distortion.

 

Revelation 3: While the heat-treated A356 aluminum cylinder heads do not have hemispherical combustion chambers, they carry 54.3-mm (2.14-inch) intake valves and 42.0-mm (1.65-inch) exhaust valves.

 Both have hollow stems to save weight; the exhaust stems are filled with sodium to dissipate excess heat.

 

Revelation 4: IHI Turbo America (formerly Warner-Ishi) manufactures the entire 80-pound supercharger—aluminum housing, aluminum rotors supported by steel shafts, and the twin air-liquid intercoolers—in a Shelbyville, Illinois, plant.

A one-way clutch on the blower’s input shaft prevents the high-inertia rotating components from back-driving the engine during lift-throttle conditions.
