The Scion FR-S, a compact sports car, has garnered a loyal following due to its engaging driving dynamics and affordability. However, many enthusiasts look for ways to enhance its performance. One popular modification is upgrading the intake and exhaust system. This article explores how a $1,000 investment in these components can significantly boost power and improve the overall driving experience.
Understanding the Basics of Intake and Exhaust Systems
Before diving into the specifics of the upgrades, it’s essential to understand how intake and exhaust systems function in a vehicle. The intake system is responsible for delivering air to the engine, while the exhaust system expels the gases produced during combustion. Improving these systems can lead to better airflow, resulting in increased engine efficiency and power output.
The Benefits of Upgrading the Intake System
Upgrading the intake system typically involves replacing the factory air filter and intake manifold with high-performance alternatives. Here are some benefits of this upgrade:
- Increased Airflow: A performance intake allows more air to enter the engine, enhancing combustion.
- Improved Throttle Response: Better airflow can lead to quicker throttle response and improved acceleration.
- Enhanced Engine Sound: Many aftermarket intakes provide a more aggressive engine sound, appealing to enthusiasts.
The Advantages of a Performance Exhaust System
Replacing the exhaust system can also yield significant performance gains. A performance exhaust system typically features larger diameter piping and less restrictive mufflers. Here are the key advantages:
- Reduced Back Pressure: A less restrictive exhaust allows exhaust gases to exit more freely, improving engine efficiency.
- Weight Reduction: Many aftermarket exhaust systems are lighter than stock components, contributing to overall performance.
- Improved Aesthetics: A performance exhaust can enhance the visual appeal of the vehicle, providing a sportier look.
Real-World Testing: The $1,000 Upgrade
To put the theory to the test, we conducted real-world testing on a Scion FR-S equipped with a $1,000 intake and exhaust upgrade. The components chosen were a high-flow cold air intake and a cat-back exhaust system, both known for their performance benefits.
Testing Methodology
The testing involved a series of controlled runs on a dyno to measure horsepower and torque before and after the upgrades. Additionally, we took the car on a track to assess real-world performance improvements.
Dyno Results
Before the upgrades, the FR-S produced 200 horsepower and 151 lb-ft of torque. After installing the intake and exhaust, the numbers increased to 220 horsepower and 165 lb-ft of torque. This represented a 10% increase in horsepower and a 9% increase in torque, showcasing the effectiveness of the upgrades.
Track Performance
On the track, the upgraded FR-S exhibited noticeable improvements in acceleration and responsiveness. Lap times improved by approximately 1.5 seconds, demonstrating the real-world benefits of the modifications.
Cost Breakdown of the Upgrade
Here’s a breakdown of the costs associated with the intake and exhaust upgrades:
- Cold Air Intake: $300
- Cat-Back Exhaust System: $700
- Total Cost: $1,000
Conclusion
Investing $1,000 in a high-performance intake and exhaust system for the Scion FR-S can yield significant power gains and improve overall driving enjoyment. The real-world testing results demonstrate that these upgrades are worth considering for any FR-S owner looking to enhance their vehicle’s performance.
