The Dodge Challenger and Charger Hellcat models have taken the automotive world by storm, renowned for their impressive power and performance. However, enthusiasts often seek to push these limits even further. This is where superchargers from companies like Whipple and Hennessey come into play, significantly enhancing the output of these already powerful machines. In this article, we will explore how these superchargers can elevate the Hellcat’s horsepower to over 750 hp.
Understanding the Hellcat Engine
The Hellcat engine is a supercharged 6.2-liter HEMI V8 that delivers an astonishing 707 hp and 650 lb-ft of torque in its stock form. This engine is designed for performance, featuring advanced technology that allows it to produce immense power while maintaining reliability. However, the potential for even greater performance exists with aftermarket modifications.
Supercharging the Hellcat
Supercharging is a method of forced induction that compresses the air entering the engine, allowing for more air and fuel to be burned, resulting in increased power output. Both Whipple and Hennessey offer supercharger kits specifically designed for the Hellcat engine, each with its unique advantages.
Whipple Supercharger Overview
The Whipple supercharger kit is known for its efficiency and power gains. It utilizes a twin-screw design that provides a high volume of compressed air, allowing for substantial increases in horsepower and torque. The Whipple system is designed to be a direct bolt-on solution, making installation relatively straightforward.
Hennessey Supercharger Overview
Hennessey Performance, on the other hand, offers a supercharger kit that focuses on maximizing performance. Their system is engineered for those looking to achieve extreme power levels, often exceeding 750 hp. Hennessey’s supercharger kits are also known for their robust build quality and performance tuning, ensuring that the engine runs smoothly even at high power levels.
Power Gains Breakdown
When comparing the power gains from both Whipple and Hennessey superchargers, it’s essential to understand the specifics of each system. Below is a breakdown of the expected power gains from each supercharger.
- Whipple Supercharger: Typically increases horsepower to around 750 hp and torque to approximately 650 lb-ft.
- Hennessey Supercharger: Can push horsepower to over 800 hp and torque to around 750 lb-ft, depending on additional modifications.
Installation Considerations
Installing a supercharger on a Hellcat is a significant modification that requires careful consideration. Both Whipple and Hennessey provide detailed installation instructions, but it’s crucial to have a professional mechanic perform the installation to ensure everything is done correctly.
- Professional Installation: Recommended to avoid potential issues.
- Tuning: Post-installation tuning is necessary to optimize performance.
- Supporting Mods: Additional upgrades may be required, such as fuel system enhancements and exhaust modifications.
Performance Testing and Results
After installation, performance testing is essential to verify the power gains and ensure the vehicle operates as intended. Many owners report significant improvements in acceleration, throttle response, and overall driving experience. Dyno testing is often used to measure the exact horsepower and torque figures achieved with the new supercharger.
Conclusion
In conclusion, both Whipple and Hennessey superchargers offer impressive power gains for the Dodge Hellcat, pushing horsepower beyond the 750 hp mark. Enthusiasts looking to enhance their Hellcat’s performance should consider these options while keeping in mind the importance of professional installation and tuning. With the right supercharger, the Hellcat can deliver an exhilarating driving experience that exceeds expectations.
