The Mitsubishi Lancer Evolution IX (Evo 9) is a high-performance vehicle known for its rally heritage and impressive engineering. One of the most popular modifications among Evo 9 enthusiasts is the installation of the Cobb Tuning Accessport, which allows for tuning adjustments to optimize performance. This article will explore the performance gains achieved through the Cobb Accessport in conjunction with various exhaust setups.
Understanding the Cobb Tuning Accessport
The Cobb Tuning Accessport is a powerful tool that provides users with the ability to reprogram their vehicle’s engine management system. This device is particularly beneficial for Evo 9 owners looking to maximize their car’s performance. The Accessport allows for real-time adjustments and data logging, making it an essential component for serious tuners.
Exhaust Systems and Their Impact on Performance
Exhaust systems play a crucial role in the overall performance of a vehicle. They help to improve airflow, reduce back pressure, and enhance engine efficiency. For the Evo 9, different exhaust setups can yield varying performance results, especially when paired with the Cobb Accessport.
Types of Exhaust Setups
- Stock Exhaust System
- Cat-Back Exhaust System
- Turbo Back Exhaust System
- High-Performance Headers
Performance Gains with Different Exhaust Setups
When the Cobb Accessport is used in conjunction with various exhaust setups, the performance gains can be significant. Below, we will analyze the expected gains for each exhaust type.
1. Stock Exhaust System
Using the Cobb Accessport with the stock exhaust system typically results in modest gains. The stock setup limits airflow, which restricts the engine’s potential.
2. Cat-Back Exhaust System
Upgrading to a cat-back exhaust system allows for improved airflow and reduced back pressure. When paired with the Cobb Accessport, users can expect gains of around 15-20 horsepower and improved throttle response.
3. Turbo Back Exhaust System
The turbo back exhaust system is a comprehensive upgrade that replaces the entire exhaust system from the turbocharger back. This setup, when used with the Cobb Accessport, can yield gains of 25-30 horsepower, as well as improved turbo spool and overall performance.
4. High-Performance Headers
Incorporating high-performance headers into the exhaust setup can significantly enhance performance. When combined with the Cobb Accessport, this modification can lead to gains of 30-40 horsepower, providing substantial improvements in power delivery and engine efficiency.
Real-World Testing and Results
To better understand the performance gains, real-world testing is essential. Many Evo 9 owners have conducted dyno tests to measure the power output with different exhaust setups and the Cobb Accessport.
- Stock Exhaust + Accessport: 280 whp
- Cat-Back + Accessport: 295 whp
- Turbo Back + Accessport: 310 whp
- Headers + Turbo Back + Accessport: 320 whp
Conclusion
The combination of the Cobb Tuning Accessport with various exhaust setups on the Evo 9 can lead to impressive performance gains. Each setup offers unique benefits, and the choice ultimately depends on the owner’s performance goals. Whether opting for a simple cat-back exhaust or a full turbo back system with headers, the improvements in horsepower and driving experience are undeniable.
Ultimately, the Evo 9 remains a favorite among car enthusiasts, and with the right tuning and exhaust modifications, its performance can be taken to exhilarating new heights.
