Building a 900+ Hp Dodge Challenger Demon: Recommended Internal Parts and Tuning Tips

by

The Dodge Challenger Demon is an iconic muscle car known for its incredible power and performance. With its supercharged 6.2-liter HEMI V8 engine, the Demon can produce over 800 horsepower right out of the factory. However, for enthusiasts looking to push their Demon’s performance beyond 900 horsepower, careful selection of internal parts and tuning is essential. This article provides a comprehensive guide on the recommended internal parts and tuning tips to achieve that power milestone.

Understanding the Dodge Challenger Demon Engine

Before diving into the specifics of building a 900+ hp Dodge Challenger Demon, it’s crucial to understand the engine’s architecture. The Demon features a robust engine design that can handle significant power enhancements. Key components include:

  • 6.2-liter supercharged HEMI V8 engine
  • Cast iron engine block
  • Aluminum cylinder heads
  • Forged steel crankshaft

To reach over 900 horsepower, upgrading certain internal components is necessary. Here’s a list of recommended parts to consider:

  • Forged Pistons: Upgrading to forged pistons can handle higher boost levels and increase reliability.
  • Forged Connecting Rods: Stronger rods are essential for withstanding the stress of increased power.
  • High-Performance Camshaft: A camshaft designed for higher RPMs can improve airflow and power output.
  • Upgraded Cylinder Heads: Ported and polished heads enhance airflow, leading to better combustion and power.
  • Aftermarket Supercharger: Consider a larger supercharger for increased boost and power.
  • High-Performance Fuel Injectors: Upgraded injectors ensure adequate fuel delivery at higher horsepower levels.
  • High-Flow Fuel Pump: A fuel pump that can supply the necessary fuel for increased power is crucial.

Tuning Tips for Maximum Performance

Once the internal components are upgraded, proper tuning is essential to harness the full potential of the engine. Here are some tuning tips:

  • ECU Remapping: Remapping the engine control unit (ECU) allows for optimized fuel and ignition timing for the new setup.
  • Dyno Tuning: A professional dyno tuning session will ensure that the car runs efficiently and safely at high power levels.
  • Boost Control: Implementing a boost controller can help manage the supercharger’s output for better performance.
  • Air-Fuel Ratio Monitoring: Keep an eye on the air-fuel ratio to avoid running too lean or too rich, which can cause engine damage.
  • Knock Sensors: Utilize knock sensors to detect any pre-ignition or knocking, ensuring safe operation under high power.

Additional Considerations for Building a High-Powered Demon

Building a 900+ hp Dodge Challenger Demon requires more than just internal upgrades and tuning. Here are additional considerations:

  • Cooling System: An upgraded cooling system is essential to manage the increased heat generated by higher horsepower.
  • Transmission Upgrades: Consider upgrading the transmission to handle the additional power without failure.
  • Suspension and Tires: Enhanced suspension and high-performance tires are necessary for better traction and handling at high speeds.
  • Braking System: Upgrading the brakes will ensure that the vehicle can stop effectively, especially at higher speeds.

Conclusion

Building a 900+ hp Dodge Challenger Demon is an exciting project that requires careful planning and execution. By selecting the right internal parts and following proper tuning tips, you can unlock the full potential of this legendary muscle car. Always remember to prioritize safety and reliability when pushing your vehicle to new performance levels.
