The 4B11T engine has gained a reputation for its performance potential, especially when modified with high-quality parts. In this article, we explore the real-world results achieved with a Cosworth downpipe and race exhaust system, showcasing how these modifications can elevate the power output to an impressive 370 horsepower.
The 4B11T Engine: An Overview
The 4B11T is a turbocharged inline-4 engine that powers various models, including the Mitsubishi Lancer Evolution X. Known for its robust design, this engine is capable of handling significant power increases with the right modifications.
Key Modifications: Cosworth Downpipe and Race Exhaust
To achieve the remarkable 370 hp, two critical components were utilized: the Cosworth downpipe and a race exhaust system. Both parts are designed to enhance exhaust flow, reduce back pressure, and improve overall engine efficiency.
Cosworth Downpipe
The Cosworth downpipe is engineered to maximize exhaust flow from the turbocharger. This component replaces the restrictive factory downpipe, allowing for quicker spool times and improved throttle response.
Race Exhaust System
The race exhaust system complements the downpipe by further reducing back pressure and enhancing the sound of the engine. This setup not only improves performance but also gives the vehicle a more aggressive tone, appealing to enthusiasts.
Performance Results
After installing the Cosworth downpipe and race exhaust, dyno testing revealed that the 4B11T engine produced an impressive 370 hp at the wheels. This significant power increase showcases the effectiveness of these modifications.
Torque Improvements
In addition to horsepower, torque also saw a notable increase. The engine delivered a peak torque figure that enhances acceleration and overall drivability, making it a well-rounded performance setup.
Installation Process
Installing the Cosworth downpipe and race exhaust requires some mechanical knowledge and the right tools. Here’s a brief overview of the installation steps:
- Lift the vehicle and secure it on jack stands.
- Remove the factory downpipe and exhaust system.
- Install the Cosworth downpipe, ensuring all connections are secure.
- Attach the race exhaust system, making sure to align all hangers properly.
- Double-check all connections and lower the vehicle.
Driving Experience
With the new modifications in place, drivers report a noticeable improvement in the driving experience. The engine responds more eagerly to throttle inputs, and the overall sound is exhilarating, making it a joy to drive.
Conclusion
The combination of a Cosworth downpipe and race exhaust has proven to be a game-changer for the 4B11T engine, achieving a remarkable 370 hp. These modifications not only enhance performance but also elevate the driving experience, making them a worthwhile investment for any enthusiast.
