The Chevy Cobalt SS is a beloved compact car known for its sporty performance and tunability. Many enthusiasts seek to push their vehicles beyond factory specifications, aiming for that coveted 300+ rear wheel horsepower mark. Turbo upgrades play a crucial role in achieving this goal. In this article, we will explore essential turbo upgrades for the Chevy Cobalt SS, focusing on options like the GT28 and GTX3584RS.
Understanding Turbochargers
Turbochargers are devices that increase the engine’s efficiency and power output by forcing more air into the combustion chamber. This process allows for a more complete combustion of fuel, resulting in increased horsepower. For the Chevy Cobalt SS, selecting the right turbocharger is vital for reaching and exceeding the 300 horsepower threshold.
Popular Turbo Options for Cobalt SS
- GT28 Turbo
- GTX3584RS Turbo
- GTX2867R Turbo
- Precision 6266 Turbo
GT28 Turbo
The GT28 turbo is a popular choice among Cobalt SS enthusiasts for its balance of performance and reliability. It is capable of providing a significant boost in horsepower while maintaining good spool characteristics. With the right supporting modifications, the GT28 can help achieve around 300+ rear wheel horsepower.
GTX3584RS Turbo
The GTX3584RS is a more advanced option that offers higher power potential. This turbo is known for its quick spool time and high efficiency, making it ideal for those looking to maximize performance. With a properly tuned setup, the GTX3584RS can easily push the Cobalt SS beyond 300 rear wheel horsepower, providing thrilling acceleration and power delivery.
Supporting Modifications
To reach the 300+ rear wheel horsepower goal, turbo upgrades alone are not enough. Supporting modifications are essential to ensure the engine can handle the increased power and maintain reliability. Here are some critical upgrades to consider:
- High-Performance Intercooler
- Upgraded Fuel Injectors
- High-Flow Fuel Pump
- Performance Exhaust System
- Engine Management System (EMS) Tune
High-Performance Intercooler
An upgraded intercooler is crucial for reducing intake temperatures, which helps prevent detonation and allows for more aggressive tuning. A larger intercooler can significantly improve the efficiency of the turbo system, making it a vital component for achieving high horsepower numbers.
Upgraded Fuel Injectors
As power increases, so does the demand for fuel. Upgrading to larger fuel injectors ensures that the engine receives enough fuel to match the increased air flow from the turbo. This upgrade is essential for maintaining the right air-fuel ratio and preventing lean conditions.
High-Flow Fuel Pump
A high-flow fuel pump is necessary to supply the increased fuel demand from the upgraded injectors. This modification ensures that the engine receives a consistent and adequate fuel supply, which is critical for achieving reliable power output.
Performance Exhaust System
A performance exhaust system helps to reduce back pressure and improve exhaust flow, allowing the turbo to spool more efficiently. This upgrade not only enhances performance but also gives the Cobalt SS a more aggressive sound.
Engine Management System (EMS) Tune
Finally, an engine management system tune is essential for optimizing performance. A professional tune will ensure that the engine runs smoothly with the new turbo and supporting modifications, maximizing horsepower while maintaining reliability.
Conclusion
Achieving 300+ rear wheel horsepower in a Chevy Cobalt SS is an exciting goal for any performance enthusiast. By selecting the right turbo upgrades, such as the GT28 or GTX3584RS, and implementing essential supporting modifications, you can unlock the full potential of your vehicle. Always remember to prioritize quality parts and professional tuning to ensure the best results and reliability.
