The Dodge Challenger SRT Hellcat is a muscle car that has been making waves in the automotive world since its introduction in 2015. With its aggressive styling, impressive performance capabilities, and powerful engine, it’s no wonder why car enthusiasts can’t get enough of this beast. But what exactly makes the Hellcat tick? In this article, we’ll delve into the heart of the matter and explore the engine that powers this iconic vehicle.
The Hellcat Engine: A Brief Overview
The Hellcat engine is a 6.2-liter supercharged V8 powerplant that produces a staggering 707 horsepower and 645 lb-ft of torque. This engine is a variant of the Chrysler 6.4-liter HEMI V8, but with a few key modifications that set it apart from its non-supercharged counterpart. The Hellcat engine features a forged steel crankshaft, forged alloy pistons, and a cast aluminum alloy cylinder block, all of which contribute to its exceptional strength and durability.
Supercharger: The Key to the Hellcat’s Power
One of the most distinctive features of the Hellcat engine is its supercharger. This is a Roots-style blower that uses a pair of intermeshing lobes to compress air and force it into the engine’s cylinders. The supercharger is driven by a belt connected to the engine’s crankshaft, and it’s capable of producing up to 11.6 psi of boost pressure. This results in a significant increase in power and torque, making the Hellcat one of the fastest production cars on the market.
How the Supercharger Works
The supercharger works by using the engine’s crankshaft to drive a pair of intermeshing lobes. As the lobes rotate, they draw in air through the supercharger’s inlet and compress it before forcing it into the engine’s cylinders. The compressed air is then mixed with fuel and ignited, resulting in a significant increase in power and torque. The supercharger is also equipped with a bypass valve that allows it to bypass excess air when the engine is under light load, which helps to improve fuel efficiency.
