In this article, we will explore the real-world results of installing a Stillen exhaust and intake on a Honda S2000, revealing the impressive 18 horsepower gain recorded on the dyno.
Overview of the Honda S2000
Launched in 1999, the Honda S2000 quickly gained a reputation as one of the best roadsters in its class. With a 2.0-liter F20C engine producing 240 horsepower at 8,300 RPM, it offered an exhilarating driving experience. The S2000’s lightweight design and rear-wheel-drive layout made it a favorite among driving enthusiasts. However, as with any performance vehicle, owners often seek ways to increase power and improve performance.
Benefits of Aftermarket Modifications
Aftermarket modifications can provide several benefits to performance cars like the Honda S2000. Some of these advantages include:
- Increased horsepower: Modifications can lead to significant gains in power output.
- Improved throttle response: Upgraded intake and exhaust systems can enhance engine responsiveness.
- Better sound: Aftermarket exhaust systems can provide a more aggressive and enjoyable exhaust note.
- Enhanced aesthetics: Many aftermarket parts offer a sportier appearance.
Stillen Exhaust and Intake Overview
The Stillen exhaust and intake system for the Honda S2000 is designed to optimize airflow, allowing the engine to breathe more freely. The exhaust system features mandrel-bent piping and a high-flow muffler, which reduces back pressure and enhances exhaust flow. The intake system includes a high-performance air filter and a larger intake tube, ensuring that the engine receives a sufficient supply of fresh air.
Dyno Testing Methodology
To measure the performance gains from the Stillen exhaust and intake installation, a Honda S2000 was taken to a reputable dyno facility. The testing process involved the following steps:
- Baseline run: The car was first tested to establish baseline horsepower and torque figures.
- Installation: The Stillen exhaust and intake systems were then installed according to the manufacturer’s specifications.
- Post-installation run: After the installation, the car was tested again to measure the new horsepower and torque levels.
Results of the Dyno Test
The results of the dyno test were impressive. The Honda S2000 showed a gain of 18 horsepower at the wheels after the Stillen exhaust and intake were installed. The baseline run recorded a power output of 220 horsepower, while the post-installation run reached 238 horsepower. This increase demonstrates the effectiveness of the Stillen modifications in enhancing engine performance.
Additional Performance Improvements
In addition to the horsepower gains, the installation of the Stillen exhaust and intake provided other performance benefits:
- Improved throttle response: Drivers reported a more immediate response when pressing the accelerator.
- Enhanced engine sound: The Stillen exhaust produced a deeper, more aggressive tone that many enthusiasts appreciate.
- Weight reduction: The aftermarket components are often lighter than stock parts, contributing to a lower overall vehicle weight.
Conclusion
The Honda S2000 is an iconic sports car that benefits greatly from aftermarket modifications. The Stillen exhaust and intake system provides a notable increase in horsepower, as evidenced by the 18 hp gain recorded on the dyno. With improved throttle response and a more aggressive exhaust note, these modifications enhance the overall driving experience. For S2000 owners looking to elevate their car’s performance, the Stillen exhaust and intake are excellent options worth considering.
