The Subaru WRX is a popular choice among car enthusiasts, especially for those looking to enhance performance through turbo upgrades. Two notable turbochargers that have gained attention in the WRX community are the FP Green and the Blouch 20G. In this article, we will compare the power gains of these two turbo options, examining their specifications, performance characteristics, and overall impact on the WRX driving experience.
Overview of Turbochargers
Turbochargers play a crucial role in enhancing engine performance by forcing more air into the combustion chamber. This allows for more fuel to be burned, resulting in increased power output. The FP Green and Blouch 20G are both designed to provide significant power gains for the Subaru WRX, but they do so in different ways.
FP Green Turbocharger
The FP Green turbocharger is known for its ability to provide a balance of power and responsiveness. It is designed for those looking to achieve higher horsepower levels without sacrificing too much drivability.
Specifications
- Compressor Wheel: 68mm
- Turbine Wheel: 60mm
- Max Horsepower: 400+ HP
- Boost Pressure: Up to 25 psi
Performance Characteristics
The FP Green turbocharger is designed to spool quickly, providing power at low RPMs. This makes it an excellent choice for street driving and daily use. Many users report a smooth power delivery and increased torque, especially in the mid-range.
Blouch 20G Turbocharger
The Blouch 20G turbocharger is another popular option among Subaru WRX enthusiasts. It is known for its high power potential and ability to support larger horsepower goals.
Specifications
- Compressor Wheel: 20G (70mm)
- Turbine Wheel: 60mm
- Max Horsepower: 450+ HP
- Boost Pressure: Up to 30 psi
Performance Characteristics
The Blouch 20G turbocharger is designed to provide strong power gains at higher RPMs. It may take slightly longer to spool compared to the FP Green, but it compensates with higher peak horsepower. This makes it a preferred choice for those looking for maximum performance on the track.
Comparative Analysis
When comparing the FP Green and Blouch 20G turbochargers, several factors come into play, including power output, spool time, and overall driving experience.
Power Output
The Blouch 20G generally offers higher peak horsepower, making it suitable for those who prioritize maximum performance. However, the FP Green provides a more balanced power delivery, making it more suitable for daily driving.
Spool Time
In terms of spool time, the FP Green has an advantage. It spools faster, providing usable power at lower RPMs, which can enhance the driving experience in everyday situations.
Driving Experience
The choice between the two turbochargers often comes down to personal preference. The FP Green is ideal for those who want a responsive turbo for street use, while the Blouch 20G is better suited for track enthusiasts looking for maximum horsepower.
Conclusion
Both the FP Green and Blouch 20G turbochargers offer significant power gains for the Subaru WRX. The best choice ultimately depends on the driver’s goals and intended use. For a balance of power and drivability, the FP Green is an excellent option. For those seeking maximum horsepower potential, the Blouch 20G stands out as a strong contender.
Final Thoughts
Upgrading to a new turbocharger is a substantial investment in your Subaru WRX’s performance. It’s essential to consider factors such as tuning, supporting modifications, and your specific driving needs before making a decision. Both the FP Green and Blouch 20G have proven themselves in the WRX community, and either option can lead to an exhilarating driving experience.
