In the world of automotive performance, enthusiasts are always seeking ways to enhance their vehicles. One method that has gained popularity is the installation of a catch can. This article explores the power gains from installing a Greddy catch can on a 2016 Subaru BRZ, detailing the testing process and results.
What is a Catch Can?
A catch can is an aftermarket component designed to capture and contain oil vapors and blow-by gases that escape from the engine’s crankcase. By preventing these substances from re-entering the intake system, a catch can can help maintain cleaner combustion and improve engine performance.
Why Install a Catch Can on a Subaru BRZ?
The Subaru BRZ, known for its lightweight design and sporty handling, can benefit from a catch can installation in several ways:
- Improved engine cleanliness
- Enhanced throttle response
- Potential power gains
Testing Methodology
To evaluate the effectiveness of the Greddy catch can, we conducted a series of tests on a 2016 Subaru BRZ. The testing process involved:
- Baseline dyno runs without the catch can
- Installation of the Greddy catch can
- Post-installation dyno runs
- Data comparison and analysis
Baseline Performance Data
Before the installation of the catch can, we conducted baseline runs on the dyno. The results were as follows:
- Horsepower: 200 hp
- Torque: 150 lb-ft
Installation of the Greddy Catch Can
The Greddy catch can was installed following the manufacturer’s instructions. The installation process included:
- Disconnecting the battery
- Removing the intake manifold cover
- Mounting the catch can
- Connecting the hoses to the crankcase and intake
Post-Installation Performance Data
After the catch can was installed, we performed another set of dyno runs. The results showed a noticeable improvement:
- Horsepower: 210 hp
- Torque: 155 lb-ft
Analysis of Results
The data collected from the dyno runs indicated a power gain of:
- 10 hp increase
- 5 lb-ft increase in torque
These gains suggest that the Greddy catch can effectively reduces oil vapor re-entry into the intake, leading to better combustion efficiency.
Additional Benefits of Catch Can Installation
Beyond power gains, installing a catch can offers several additional benefits:
- Reduced carbon buildup on intake valves
- Longer engine life due to cleaner operation
- Improved fuel efficiency
Conclusion
The testing of the Greddy catch can on a 2016 Subaru BRZ demonstrated clear power gains and improved engine performance. For enthusiasts looking to enhance their vehicle’s capabilities, a catch can is a worthwhile investment that not only boosts horsepower but also contributes to the longevity and efficiency of the engine.
