The Subaru BRZ FA20 is a beloved sports car known for its lightweight design and engaging driving experience. One of the most popular modifications among enthusiasts is the installation of an aftermarket intake system. The HKS Super Power Flow Intake is a well-regarded option that promises to enhance performance. This article explores the performance gains achieved with the HKS Super Power Flow Intake through before and after dyno results.
Understanding the HKS Super Power Flow Intake
The HKS Super Power Flow Intake is designed to improve airflow to the engine, allowing for better combustion and increased power output. The intake features a high-flow air filter and a specially designed intake pipe that reduces restrictions compared to the factory setup. This modification is popular among BRZ owners looking to unlock more horsepower and torque.
Before Dyno Results
Before installing the HKS Super Power Flow Intake, it is essential to establish a baseline for performance. The stock BRZ FA20 engine was tested on a dynamometer to measure its power output. The following are the key specifications from the baseline dyno run:
- Peak Horsepower: 200 hp at 7,000 RPM
- Peak Torque: 151 lb-ft at 6,400 RPM
- Engine Configuration: Naturally aspirated 2.0L FA20
These numbers represent the factory performance of the BRZ FA20 engine. With the baseline established, the next step was to install the HKS Super Power Flow Intake and conduct another dyno run.
Installation of HKS Super Power Flow Intake
The installation of the HKS Super Power Flow Intake is relatively straightforward. It typically involves removing the factory airbox, installing the new intake pipe, and securing the high-flow air filter. This process can usually be completed in a couple of hours with basic tools and mechanical knowledge.
After Dyno Results
After the installation of the HKS Super Power Flow Intake, the BRZ was taken back to the dyno for testing. The results showed a significant improvement in performance:
- Peak Horsepower: 220 hp at 7,200 RPM
- Peak Torque: 158 lb-ft at 6,500 RPM
- Power Gain: +20 hp
- Torque Gain: +7 lb-ft
The dyno results indicate a noticeable increase in both horsepower and torque, showcasing the effectiveness of the HKS Super Power Flow Intake in enhancing engine performance.
Performance Analysis
The increase in horsepower and torque translates to a more responsive engine, particularly in the mid to high RPM range. Drivers can expect improved acceleration and a more engaging driving experience. The enhanced airflow provided by the HKS intake allows the engine to breathe better, leading to these performance gains.
Throttle Response
One of the most noticeable changes after installing the HKS intake is the improved throttle response. The engine reacts more quickly to driver inputs, making the car feel more agile and lively on the road.
Sound Improvement
In addition to performance gains, the HKS Super Power Flow Intake also enhances the sound of the BRZ. The intake produces a deeper, more aggressive engine note that many enthusiasts find appealing, adding to the overall driving experience.
Conclusion
The HKS Super Power Flow Intake is a worthwhile upgrade for Subaru BRZ FA20 owners looking to boost performance. The before and after dyno results demonstrate significant gains in horsepower and torque, along with improved throttle response and sound. This modification not only enhances the driving experience but also showcases the potential of the BRZ platform for performance tuning.
Further Modifications
For those considering further performance enhancements, the HKS intake can serve as a foundation for additional modifications. Some recommended upgrades to complement the intake include:
- High-performance exhaust system
- ECU tuning for optimized air-fuel ratios
- Upgraded fuel injectors
- Aftermarket headers
These modifications can work in tandem with the HKS intake to maximize the performance potential of the BRZ FA20 engine.
Final Thoughts
In conclusion, the HKS Super Power Flow Intake offers substantial performance gains for the Subaru BRZ FA20. The documented dyno results highlight the benefits of this modification, making it a popular choice among car enthusiasts. Whether you are a casual driver or a dedicated racer, upgrading to the HKS intake can significantly enhance your vehicle’s performance and driving enjoyment.
