The Dodge Challenger Hellcat is a beast on the road, boasting an impressive 717 horsepower straight from the factory. However, for enthusiasts looking to push the limits even further, there are several power modifications available that can elevate this muscle car’s performance to over 900 horsepower. In this article, we will explore the top modifications that can help you achieve this remarkable power boost.
Performance Upgrades to Consider
- Supercharger Upgrades
- High-Performance Exhaust Systems
- Cold Air Intakes
- ECU Tuning
- Upgraded Fuel Injectors
- High-Performance Intercoolers
Supercharger Upgrades
One of the most effective ways to increase horsepower is by upgrading the supercharger. The Hellcat comes equipped with a 2.4L supercharger, but aftermarket options can provide even more boost. Consider a larger supercharger or a twin-screw supercharger that can deliver higher boost levels and more efficient airflow.
Popular Supercharger Options
- Whipple Superchargers
- Kenne Bell Superchargers
- Magnuson Superchargers
High-Performance Exhaust Systems
Upgrading the exhaust system can significantly improve engine performance by enhancing exhaust flow. A high-performance exhaust system reduces back pressure, allowing the engine to breathe better and produce more power. Look for systems that include headers, catalytic converters, and mufflers designed for maximum flow.
Benefits of Upgraded Exhaust Systems
- Improved horsepower and torque
- Enhanced engine sound
- Weight reduction
Cold Air Intakes
A cold air intake system allows your Hellcat’s engine to draw in cooler, denser air, which can lead to improved combustion and increased horsepower. These systems are typically easy to install and can provide noticeable gains in both power and throttle response.
Recommended Cold Air Intake Brands
- K&N Engineering
- Airaid
- Volant Performance
ECU Tuning
After making performance modifications, it is crucial to tune the engine’s ECU (Engine Control Unit) to optimize performance. ECU tuning adjusts fuel maps, ignition timing, and other parameters to ensure the engine runs efficiently and safely with the new modifications.
Popular Tuning Solutions
- DiabloSport
- HP Tuners
- SCT Performance
Upgraded Fuel Injectors
To support higher horsepower levels, upgrading the fuel injectors is essential. Stock injectors may not provide enough fuel for increased power, leading to lean conditions that can damage the engine. High-performance fuel injectors will deliver the necessary fuel to match your power goals.
Top Fuel Injector Brands
- Injector Dynamics
- DeatschWerks
- FIC (Fuel Injector Clinic)
High-Performance Intercoolers
A high-performance intercooler is vital for maintaining optimal intake temperatures, especially when increasing boost levels. A larger intercooler can help reduce the temperature of the compressed air before it enters the engine, resulting in denser air and improved performance.
Benefits of Upgrading Your Intercooler
- Lower intake temperatures
- Increased horsepower
- Improved engine reliability
Conclusion
Boosting your Dodge Challenger Hellcat’s output from 717 horsepower to over 900 horsepower is an achievable goal with the right modifications. By investing in supercharger upgrades, high-performance exhaust systems, cold air intakes, ECU tuning, upgraded fuel injectors, and high-performance intercoolers, you can unleash the full potential of your muscle car. Always remember to balance performance upgrades with reliability and safety to ensure a thrilling yet dependable driving experience.
