The GR86 has become a popular choice among car enthusiasts looking to enhance performance and driving experience. One of the most effective upgrades for this vehicle is the installation of Perrin headers. In this article, we will explore the performance gains achieved with Perrin headers on the GR86, showcasing before and after dyno results.
Understanding the Importance of Headers
Headers play a crucial role in the performance of an engine. They are designed to improve exhaust flow, which can lead to increased horsepower and torque. By replacing the factory headers with high-performance options like those from Perrin, drivers can unlock the full potential of their GR86.
Before Dyno Results
Before the installation of Perrin headers, the GR86 was tested on a dynamometer to establish baseline performance metrics. The following results were recorded:
- Horsepower: 200 hp at the wheels
- Torque: 150 lb-ft at the wheels
- RPM Range: Peak power achieved at 7,000 RPM
Installation of Perrin Headers
Installing Perrin headers involves several steps, including lifting the vehicle, removing the factory headers, and fitting the new headers into place. It is recommended that this installation is performed by a professional or an experienced enthusiast to ensure optimal performance and avoid any issues.
After Dyno Results
After the installation of Perrin headers, the GR86 was once again tested on the dynamometer. The results showed significant improvements in performance:
- Horsepower: 220 hp at the wheels
- Torque: 165 lb-ft at the wheels
- RPM Range: Peak power achieved at 7,200 RPM
Performance Gains Analysis
The data from the before and after dyno tests clearly illustrates the performance gains achieved with the installation of Perrin headers. The GR86 experienced an increase of 20 horsepower and 15 lb-ft of torque at the wheels. This improvement not only enhances acceleration but also contributes to a more engaging driving experience.
Additional Benefits of Perrin Headers
In addition to the performance gains, Perrin headers offer several other benefits:
- Improved Exhaust Sound: Enhanced engine sound that is more aggressive and sporty.
- Better Engine Efficiency: Optimized exhaust flow contributes to overall engine efficiency.
- Durability: High-quality materials ensure long-lasting performance under extreme conditions.
Conclusion
The installation of Perrin headers on the GR86 provides substantial performance gains, as evidenced by the dyno results. With an increase in horsepower and torque, as well as additional benefits such as improved sound and efficiency, it is a worthwhile investment for any GR86 owner looking to enhance their vehicle’s performance.
