The Mazda RX-7 is an iconic sports car known for its lightweight design and rotary engine. Enthusiasts often seek ways to enhance its performance, and one of the most effective upgrades is the installation of a high-performance intake system. Recent dyno tests have shown that the COSO Racing Intake can provide significant horsepower gains, making it a popular choice among RX-7 owners.
Understanding the Mazda RX-7 and Its Engine
The RX-7 features a unique rotary engine, which is different from traditional piston engines. This engine design allows for a lightweight and compact form factor, but it also requires specific tuning and modifications to maximize its potential. The COSO Racing Intake is designed to improve airflow into the engine, which can lead to increased horsepower and torque.
What is the COSO Racing Intake?
The COSO Racing Intake is an aftermarket performance part specifically engineered for the Mazda RX-7. It is designed to replace the factory intake system, allowing for better airflow and improved engine performance. Some key features include:
- High-flow air filter for improved filtration and airflow
- Lightweight construction to reduce overall weight
- Enhanced design to minimize air turbulence
Dyno Testing Results
To evaluate the performance of the COSO Racing Intake, a series of dyno tests were conducted on a stock Mazda RX-7. The results were impressive, showing a gain of up to 60 horsepower at the wheels. This increase in power is significant and demonstrates the effectiveness of the intake system.
Testing Methodology
The testing involved a controlled environment where the RX-7 was put on a dynamometer to measure horsepower and torque before and after the installation of the COSO Racing Intake. Key aspects of the testing included:
- Baseline runs with the stock intake system
- Installation of the COSO Racing Intake
- Multiple runs to ensure consistent and accurate results
Results Overview
The dyno results revealed an average increase of 60 horsepower across multiple runs, with torque also showing a noticeable improvement. The following figures highlight the performance gains:
- Stock horsepower: 180 hp
- Post-installation horsepower: 240 hp
- Torque increase: 15 lb-ft
Benefits of Upgrading to the COSO Racing Intake
Upgrading to the COSO Racing Intake offers several advantages beyond just horsepower gains. These include:
- Improved throttle response for a more engaging driving experience
- Enhanced engine sound, providing a sportier auditory experience
- Potential for better fuel efficiency under certain driving conditions
Installation Process
The installation of the COSO Racing Intake is relatively straightforward and can be accomplished with basic tools. The following steps outline the installation process:
- Gather necessary tools: socket set, screwdrivers, and pliers
- Remove the factory intake system from the RX-7
- Install the COSO Racing Intake, ensuring all connections are secure
- Recheck all fittings and start the engine to verify proper installation
Conclusion
The dyno tests clearly demonstrate that the COSO Racing Intake can provide substantial performance gains for the Mazda RX-7. With an increase of 60 horsepower and improved throttle response, this upgrade is a valuable investment for any RX-7 enthusiast looking to enhance their driving experience. Whether on the track or the street, the COSO Racing Intake delivers real-world results that are hard to ignore.
