The Scion FR-S is a popular sports car that has garnered a loyal following due to its lightweight design and engaging driving experience. Many enthusiasts look to enhance the performance of their FR-S, and two popular modifications are the Perrin Cold Air Intake and the Accessport. In this article, we will explore how these modifications can impact horsepower and overall performance.
Understanding the Scion FR-S
The Scion FR-S, a collaborative effort between Toyota and Subaru, is known for its rear-wheel-drive layout and balanced chassis. With a 2.0-liter flat-four engine, it delivers a thrilling driving experience. However, many owners seek to increase horsepower to enhance its performance further.
The Role of Cold Air Intakes
Cold air intakes are designed to improve engine performance by increasing airflow. By drawing cooler air from outside the engine bay, these intakes can help the engine breathe better, resulting in improved combustion efficiency.
Benefits of the Perrin Cold Air Intake
The Perrin Cold Air Intake is a popular choice among FR-S owners. Here are some benefits:
- Increased Airflow: The Perrin design allows for better airflow compared to the stock intake.
- Improved Sound: Many drivers enjoy the more aggressive engine sound that comes with the intake.
- Enhanced Performance: The increased airflow can lead to notable gains in horsepower.
What is the Accessport?
The Accessport is a handheld tuning device that allows users to modify the engine’s ECU settings. It provides the ability to upload custom tunes, monitor performance metrics, and reset check engine lights.
How the Accessport Enhances Performance
Using the Accessport in conjunction with the Perrin Cold Air Intake can lead to significant performance improvements. Here’s how:
- Custom Tuning: The Accessport allows for custom tuning that can optimize the engine’s performance based on the new intake.
- Increased Horsepower: Many users report horsepower gains after remapping the ECU with the Accessport.
- Real-Time Monitoring: Drivers can monitor engine metrics to ensure everything is performing as expected.
Expected Horsepower Gains
One of the most common questions among FR-S enthusiasts is, “How much horsepower can I expect from these modifications?” The answer can vary based on several factors, including the specific tune used and the condition of the vehicle.
Typical Gains from the Perrin Cold Air Intake
With the installation of the Perrin Cold Air Intake alone, drivers can typically expect to see:
- Horsepower Increase: Approximately 5-10 horsepower at the wheels.
- Torque Increase: Similar increases in torque can also be observed.
Expected Gains with Accessport Tuning
When combining the Perrin Cold Air Intake with a proper tune from the Accessport, the gains can be more substantial:
- Horsepower Increase: Up to 15-25 horsepower at the wheels, depending on the tune.
- Torque Increase: Torque gains can also be in the range of 10-20 lb-ft.
Factors Influencing Performance Gains
While the numbers above are typical, several factors can influence the actual performance gains experienced by drivers:
- Vehicle Condition: A well-maintained engine will perform better than one that has not been cared for.
- Fuel Quality: Higher octane fuel can improve performance when tuned appropriately.
- Other Modifications: Additional upgrades such as exhaust systems can further enhance gains.
Conclusion
In summary, upgrading your Scion FR-S with a Perrin Cold Air Intake and an Accessport can yield significant horsepower gains. While individual results may vary, many drivers report improved performance and an enhanced driving experience. For those looking to get the most out of their FR-S, these modifications are worth considering.
