The quest for performance in automotive engineering often leads enthusiasts to explore various modifications. One such modification that has gained attention in the performance community is the installation of polyurethane bushings. This article delves into a real-world case study where a 350 horsepower Camaro experienced a remarkable 30 horsepower increase after equipping Energy Suspension polyurethane bushings.
Understanding Polyurethane Bushings
Polyurethane bushings are designed to replace the factory rubber bushings found in a vehicle’s suspension system. Unlike rubber, polyurethane offers several advantages:
- Durability: Polyurethane is more resistant to wear and tear compared to rubber.
- Performance: These bushings provide improved handling and responsiveness.
- Reduced Flex: Polyurethane bushings maintain their shape under stress, leading to better power transfer.
The Camaro Project
The project focused on a 350 horsepower Camaro, a popular choice among car enthusiasts. The goal was to evaluate the impact of Energy Suspension polyurethane bushings on the vehicle’s overall performance, specifically its horsepower output.
Initial Setup
The Camaro was initially equipped with standard rubber bushings. Prior to the modification, the vehicle underwent a baseline dyno test to establish its horsepower output. The results confirmed a steady 350 horsepower at the wheels.
Installation of Polyurethane Bushings
The installation process involved replacing the factory rubber bushings with Energy Suspension polyurethane bushings. This task required specific tools and expertise, as it involved disassembling parts of the suspension system. The following steps were taken during installation:
- Lift the vehicle and secure it on jack stands.
- Remove the wheels for better access to the suspension components.
- Detach the suspension arms and remove the old rubber bushings.
- Install the new polyurethane bushings according to the manufacturer’s instructions.
- Reassemble the suspension and wheels.
Post-Installation Testing
After the installation of the polyurethane bushings, the Camaro was taken back to the dyno for a follow-up horsepower test. The results were astonishing, showcasing a 30 horsepower increase, bringing the total to 380 horsepower at the wheels.
Factors Contributing to the Power Increase
Several factors contributed to the observed increase in horsepower:
- Improved Suspension Geometry: The stiffer bushings reduced unwanted flex, allowing for more precise handling and better power transfer to the wheels.
- Reduced Wheel Hop: Polyurethane bushings minimized wheel hop during acceleration, allowing for smoother power delivery.
- Enhanced Traction: The increased stability of the suspension improved tire contact with the road, enhancing overall grip and performance.
Real-World Implications
The results of this modification highlight the real-world implications of using polyurethane bushings in performance vehicles. The increase in horsepower is not just a number; it translates into tangible benefits for drivers:
- Improved Driving Experience: Enhanced handling and responsiveness lead to a more engaging driving experience.
- Increased Performance: The additional horsepower allows for quicker acceleration and improved track times.
- Cost-Effective Upgrade: Compared to other performance modifications, the installation of bushings offers a significant return on investment.
Conclusion
The installation of Energy Suspension polyurethane bushings on a 350 horsepower Camaro resulted in a notable 30 horsepower increase. This case study serves as a testament to the benefits of upgrading to polyurethane bushings, demonstrating how even small modifications can lead to significant performance gains. For automotive enthusiasts looking to enhance their vehicle’s performance, this upgrade is certainly worth considering.
