The Chevy Cobalt SS Turbo is a favorite among car enthusiasts for its performance and affordability. If you’re looking to increase your horsepower without breaking the bank, there are several modifications you can make for under $300. In this article, we will explore cheap yet effective mods that can help you boost your Cobalt’s power by 25 HP using boost controllers and intercoolers.
Understanding Boost Controllers
Boost controllers are devices that regulate the amount of boost pressure produced by the turbocharger. By adjusting the boost levels, you can significantly increase your engine’s power output. Here are two popular types of boost controllers:
- Manual Boost Controllers: These are simple devices that allow you to adjust boost pressure manually. They are typically more affordable and easy to install.
- Electronic Boost Controllers: These offer more precise control over boost levels and can be adjusted on-the-fly. They tend to be more expensive but can provide better performance.
Installing a Manual Boost Controller
Installing a manual boost controller is one of the most cost-effective ways to increase power. Here’s a step-by-step guide:
- Gather Tools: You will need basic tools such as a wrench, pliers, and a screwdriver.
- Locate the Boost Source: Find the vacuum line that connects to the wastegate actuator.
- Install the Controller: Disconnect the vacuum line and connect it to the boost controller. Then, run a new line from the controller to the wastegate.
- Adjust Settings: Start with a low boost setting and gradually increase it while monitoring your engine’s performance.
Benefits of Upgrading the Intercooler
Upgrading your intercooler is another effective way to improve performance. The intercooler cools the air entering the engine, allowing for denser air and more power. Here’s why you should consider upgrading:
- Improved Air Density: Cooler air is denser, which means more oxygen for combustion.
- Reduced Knock: A better intercooler can help prevent engine knock, allowing for more aggressive tuning.
- Increased Reliability: A larger intercooler can handle higher boost levels without overheating.
Choosing the Right Intercooler
When selecting an intercooler for your Cobalt SS Turbo, consider the following factors:
- Size: A larger intercooler can provide better cooling but may require modifications for installation.
- Core Design: Look for a bar-and-plate design for better cooling efficiency.
- Material: Aluminum intercoolers are lightweight and offer good thermal conductivity.
Installation Tips for Intercoolers
Installing a new intercooler can be a bit more complex than a boost controller. Here are some tips to ensure a smooth installation:
- Read Instructions: Always follow the manufacturer’s instructions for installation.
- Check Fitment: Before finalizing the installation, ensure the intercooler fits well within the engine bay.
- Seal Connections: Use silicone couplers to ensure tight seals and prevent boost leaks.
Combining Mods for Maximum Effect
For the best results, consider combining a boost controller with an upgraded intercooler. This combination allows you to run higher boost levels safely, maximizing your horsepower gains. Here’s how to effectively combine these mods:
- Start with the Controller: Install the boost controller first and adjust the settings gradually.
- Monitor Performance: Keep an eye on your engine’s performance and make adjustments as needed.
- Upgrade the Intercooler: Once you’re comfortable with the boost levels, install the intercooler for enhanced performance.
Conclusion
Modifying your Chevy Cobalt SS Turbo doesn’t have to be expensive. By investing in a manual boost controller and an upgraded intercooler, you can easily increase your horsepower by 25 HP for under $300. With these modifications, you’ll enjoy a more powerful and responsive driving experience. Happy tuning!
