The world of automotive performance is continuously evolving, and enthusiasts are always on the lookout for ways to enhance their vehicles. One popular modification among car enthusiasts is the installation of polyurethane bushings. In this article, we will explore the real-world testing of polyurethane bushings on a 650 horsepower Toyota Supra, focusing on the power and handling results.
Understanding Polyurethane Bushings
Polyurethane bushings are often chosen over traditional rubber bushings due to their superior durability and performance characteristics. They provide several benefits, including:
- Increased stiffness: Polyurethane bushings offer greater stiffness, which helps improve handling and responsiveness.
- Enhanced durability: They are more resistant to wear and tear compared to rubber, leading to a longer lifespan.
- Reduced deflection: Less deflection translates to improved alignment and handling precision.
The 650 HP Supra: A Performance Beast
The Toyota Supra has long been a favorite among performance enthusiasts. With a powerful 650 horsepower engine, this model is designed for speed and agility. However, to maximize its potential, every component must work in harmony, including the bushings.
Stock vs. Polyurethane Bushings
Before diving into the results of our testing, it’s essential to understand the differences between stock rubber bushings and polyurethane bushings. Stock bushings are designed for comfort and noise reduction, while polyurethane bushings prioritize performance and responsiveness.
Testing Methodology
To accurately assess the impact of polyurethane bushings on the 650 HP Supra, we conducted a series of tests under controlled conditions. Our testing methodology included:
- Track testing: We took the Supra to a closed track to measure lap times and handling characteristics.
- Road testing: Real-world driving scenarios were simulated to evaluate comfort and performance.
- Data collection: We utilized data logging equipment to record various performance metrics throughout the tests.
Results of the Testing
The results of our testing were impressive, showcasing the significant benefits of upgrading to polyurethane bushings. Here are the key findings:
- Improved lap times: The Supra recorded a reduction in lap times, indicating better handling and cornering capabilities.
- Enhanced steering response: Drivers reported a noticeable increase in steering precision and feedback.
- Reduced body roll: The vehicle exhibited less body roll during aggressive cornering, contributing to improved stability.
Driving Experience with Polyurethane Bushings
While performance metrics are crucial, the driving experience is equally important. Here’s what we observed:
- Comfort level: Although polyurethane bushings are stiffer, the overall ride comfort was still acceptable for daily driving.
- Noise levels: Some increase in road noise was noted, which is typical with performance bushings.
- Confidence in handling: Drivers felt more confident pushing the vehicle to its limits, thanks to the improved handling characteristics.
Conclusion
Upgrading to polyurethane bushings on a 650 HP Supra resulted in significant improvements in power and handling. The testing demonstrated enhanced performance metrics, better steering response, and increased driver confidence. For enthusiasts looking to maximize their vehicle’s potential, polyurethane bushings are a worthwhile investment.
As always, it is essential to consider your driving style and preferences when making modifications. While polyurethane bushings provide many benefits, they may not be suitable for every driver. However, for those seeking enhanced performance, they represent an excellent choice.
