When it comes to building a high-performance engine capable of reaching 400 wheel horsepower (WHP), selecting the right turbocharger is crucial. The Mitsubishi TD05H-20G and TD06H-20G are two popular choices among enthusiasts. This guide will delve into the specifics of each turbocharger, helping you make an informed decision for your application.
Understanding the Basics of Turbochargers
Turbochargers are essential components that increase an engine’s efficiency and power output by forcing more air into the combustion chamber. The choice of turbocharger can significantly affect performance, throttle response, and overall drivability.
Mitsubishi TD05H-20G Overview
The TD05H-20G is a well-known turbocharger in the performance community. It is favored for its balance of power and response, making it suitable for various applications.
Specifications
- Compressor Wheel Diameter: 20G
- Turbine Wheel Diameter: 60mm
- Compressor A/R: 0.50
- Turbine A/R: 0.63
Performance Characteristics
The TD05H-20G can support power levels up to approximately 400 WHP on a well-tuned setup. Its design allows for quick spool times, making it ideal for street applications where responsiveness is key.
Mitsubishi TD06H-20G Overview
The TD06H-20G is another option that provides a higher flow rate compared to the TD05H-20G. This turbocharger is often chosen for applications requiring more power without sacrificing too much responsiveness.
Specifications
- Compressor Wheel Diameter: 20G
- Turbine Wheel Diameter: 64mm
- Compressor A/R: 0.60
- Turbine A/R: 0.82
Performance Characteristics
The TD06H-20G can support similar power levels but does so with a larger turbine, which can provide increased top-end power. However, this can sometimes lead to a slight delay in spool time compared to the TD05H-20G.
Comparing TD05H-20G and TD06H-20G
When selecting between the TD05H-20G and TD06H-20G, several factors come into play. Here’s a comparison to help you decide which turbocharger is best for your 400 WHP application.
Spool Time
The TD05H-20G typically spools faster due to its smaller turbine, making it preferable for applications where quick throttle response is essential, such as daily driving or autocross.
Top-End Power
The TD06H-20G, with its larger turbine, can produce more power at higher RPMs. This makes it a suitable choice for track-oriented builds where maximum power is desired.
Efficiency
Both turbochargers are efficient in their own right, but the TD05H-20G may provide better efficiency for street applications, while the TD06H-20G excels in high-performance scenarios.
Choosing the Right Turbocharger for Your Application
Deciding between the TD05H-20G and TD06H-20G ultimately depends on your specific goals and driving style. Here are some tips to help you make your choice:
- If you prioritize quick response and daily drivability, consider the TD05H-20G.
- If your focus is on maximum power and high RPM performance, the TD06H-20G may be the better option.
- Evaluate your engine setup and tuning capabilities to ensure compatibility with your chosen turbocharger.
Conclusion
Both the Mitsubishi TD05H-20G and TD06H-20G are excellent choices for achieving 400 WHP. Your decision should be based on your specific performance goals, driving style, and engine setup. By understanding the strengths and weaknesses of each turbocharger, you can select the one that best fits your needs.
