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.
