Building a 900+ Hp Dodge Challenger 6.2 Hellcat: Turbocharger vs Supercharger Showdown

by

The Dodge Challenger 6.2 Hellcat is already a powerhouse with its supercharged HEMI V8 engine. However, for enthusiasts looking to push the limits beyond 900 horsepower, the debate between turbochargers and superchargers becomes crucial. This article explores the advantages and disadvantages of both forced induction methods, helping you decide which is best for your Hellcat build.

Understanding Forced Induction

Forced induction systems increase an engine’s power output by forcing more air into the combustion chamber. This process allows for more fuel to be burned, resulting in increased horsepower. The two primary types of forced induction are turbochargers and superchargers, each with unique characteristics.

Turbochargers

A turbocharger uses exhaust gas to spin a turbine, which compresses the incoming air. This method has several benefits:

  • Efficiency: Turbochargers can provide significant power increases with less engine load.
  • Power Band: They can produce power at higher RPMs, making them suitable for racing applications.
  • Fuel Economy: When tuned correctly, they can improve fuel efficiency compared to supercharged setups.

However, turbochargers also have drawbacks:

  • Turbo Lag: There can be a delay in power delivery as the turbo spools up.
  • Complexity: The installation process can be more complicated due to additional components like intercoolers and piping.
  • Heat Management: They can generate significant heat, requiring careful management to avoid engine damage.

Superchargers

Superchargers, on the other hand, are mechanically driven by the engine’s crankshaft. They provide immediate power without the lag associated with turbochargers. Here are some advantages:

  • Instant Power: Superchargers provide immediate boost, enhancing throttle response.
  • Simplicity: Generally easier to install, as they often require fewer modifications.
  • Consistent Power Delivery: They maintain boost across a wider RPM range, ideal for street applications.

However, superchargers come with their own set of disadvantages:

  • Engine Load: They draw power from the engine, which can reduce overall efficiency.
  • Heat Generation: Superchargers can produce more heat, necessitating better cooling solutions.
  • Limited Power Band: They may not provide as much power at high RPMs compared to turbochargers.

Power Goals: 900+ HP Build

When aiming for a build that exceeds 900 horsepower, the choice between a turbocharger and a supercharger can significantly impact the final outcome. Here’s what to consider:

Turbocharger Setup

For a turbocharged setup, you might consider the following components:

  • High-flow turbocharger capable of supporting over 900 HP.
  • Upgraded fuel injectors and fuel pump to accommodate increased fuel demand.
  • Intercooler to reduce intake temperatures and increase efficiency.
  • Custom tuning to optimize performance and reliability.

Supercharger Setup

For a supercharged setup, consider these components:

  • High-performance supercharger that can deliver the necessary boost.
  • Upgraded cooling system to manage increased heat output.
  • Enhanced fuel system, including larger injectors and pumps.
  • Custom tuning to ensure optimal performance and engine safety.

Cost Considerations

Building a 900+ HP Dodge Challenger involves significant investment. Here’s a breakdown of potential costs for both setups:

Turbocharger Costs

The costs associated with a turbocharger setup can vary widely:

  • Turbocharger: $1,500 – $5,000
  • Intercooler: $500 – $1,500
  • Fuel system upgrades: $1,000 – $3,000
  • Tuning: $500 – $1,500

Supercharger Costs

For a supercharger setup, expect the following costs:

  • Supercharger kit: $6,000 – $10,000
  • Cooling system upgrades: $500 – $2,000
  • Fuel system upgrades: $1,000 – $3,000
  • Tuning: $500 – $1,500

Conclusion

Choosing between a turbocharger and a supercharger for your 900+ HP Dodge Challenger 6.2 Hellcat ultimately depends on your goals, driving style, and budget. Turbochargers offer efficiency and high RPM power, while superchargers provide immediate throttle response and simplicity. Evaluate your needs carefully to make the best decision for your build.
