In the world of automotive performance, the Mitsubishi Lancer Evolution X (Evo X) has always been a favorite among enthusiasts. With its turbocharged engine and all-wheel-drive system, the Evo X is a platform that offers immense potential for tuning. In this article, we will explore the real-world results of achieving 400 horsepower using Greddy intake, exhaust, and ECU tuning.
Understanding the Evo X Platform
The Evo X is equipped with a 2.0-liter turbocharged inline-4 engine known as the 4B11T. This engine is capable of producing impressive power figures, but with the right modifications, it can unleash even more potential. The combination of a strong engine, advanced all-wheel-drive system, and lightweight chassis makes the Evo X a prime candidate for performance upgrades.
Greddy Intake System
The first step in our quest for 400 horsepower was the installation of the Greddy intake system. This high-performance intake is designed to improve airflow to the engine, resulting in better throttle response and increased power output. The Greddy intake features a larger diameter piping and a high-flow air filter that allows for improved air intake efficiency.
Installation Process
Installing the Greddy intake system is relatively straightforward. Here are the steps involved:
- Remove the factory intake system components.
- Install the Greddy intake piping and secure it in place.
- Attach the high-flow air filter to the end of the intake piping.
- Reconnect any necessary sensors and ensure all connections are secure.
Greddy Exhaust System
Next, we turned our attention to the exhaust system. The Greddy exhaust system is designed to reduce back pressure and improve exhaust flow. This results in a more efficient engine and a more aggressive sound. The exhaust system includes high-quality materials and precise engineering to ensure optimal performance.
Benefits of Upgrading the Exhaust
Upgrading to a Greddy exhaust system offers several benefits:
- Increased horsepower and torque.
- Improved throttle response.
- Enhanced sound quality.
- Reduced weight compared to the factory exhaust.
ECU Tuning
The final piece of the puzzle is ECU tuning. After installing the Greddy intake and exhaust systems, it is essential to recalibrate the engine’s computer to take full advantage of the modifications. ECU tuning adjusts fuel maps, ignition timing, and boost levels to optimize performance.
Tuning Process
The tuning process typically involves the following steps:
- Connect the vehicle to a tuning software via an OBD-II interface.
- Upload the baseline map to assess current performance.
- Make adjustments to the fuel and ignition maps based on the new intake and exhaust setup.
- Test the vehicle on a dynamometer to verify power gains and ensure reliability.
Real-World Results
After completing the installation of the Greddy intake and exhaust systems and performing ECU tuning, we took the Evo X to the dyno. The results were impressive, with the vehicle producing a peak horsepower of 400 at the wheels. This power output is a significant increase over the stock figures, showcasing the effectiveness of the modifications.
Performance Metrics
Here are some key performance metrics from the dyno session:
- Peak Horsepower: 400 hp
- Peak Torque: 360 lb-ft
- Boost Pressure: 24 psi
Conclusion
Achieving 400 horsepower with a Greddy intake, exhaust, and ECU tuning on the Evo X is a testament to the potential of this platform. These modifications not only enhance performance but also provide a thrilling driving experience. For enthusiasts looking to unlock the full potential of their Evo X, investing in quality parts like those from Greddy is a step in the right direction.
Further Considerations
While the results are impressive, there are additional considerations for those looking to push their Evo X even further:
- Consider upgrading the intercooler for better cooling efficiency.
- Invest in a high-performance fuel pump and injectors for optimal fuel delivery.
- Explore options for a larger turbocharger for increased power potential.
