Turbocharged cars have gained immense popularity among automotive enthusiasts due to their ability to deliver significant power increases with relatively simple modifications. One of the most critical components in achieving these performance gains is the fuel pump. Upgrading your fuel pump can help ensure that your turbocharged engine receives the optimal amount of fuel, which is essential for maximizing horsepower and performance.
Understanding the Importance of Fuel Delivery
The fuel pump is responsible for delivering fuel from the tank to the engine at the correct pressure. In turbocharged applications, the demand for fuel increases significantly as the engine requires more fuel to match the increased air intake. A stock fuel pump may not be able to supply enough fuel, leading to issues such as lean air-fuel mixtures, reduced performance, and potential engine damage.
Signs You Need a Fuel Pump Upgrade
- Loss of power during acceleration
- Engine misfires or rough idling
- Increased fuel consumption
- Check engine light related to fuel system issues
- Difficulty starting the engine
Choosing the Right Fuel Pump for Your Turbocharged Car
When selecting a fuel pump, there are several factors to consider, including the type of turbocharger, engine size, and desired power output. Here are some key points to keep in mind:
- Fuel Flow Rate: Ensure the pump can deliver the required flow rate at the desired pressure.
- Compatibility: Check if the pump is compatible with your vehicle’s fuel system.
- Quality: Opt for reputable brands known for reliability and performance.
- Installation: Consider ease of installation and whether you need additional modifications.
Popular Fuel Pump Upgrades for Turbocharged Cars
There are numerous fuel pump options available for turbocharged vehicles. Here are some popular upgrades:
- Walbro 255 LPH Fuel Pump: A widely used pump that offers excellent flow rates and is compatible with many vehicles.
- AEM 340 LPH High Flow Fuel Pump: Known for its high flow rate and reliability, suitable for higher horsepower applications.

Installation Tips for Fuel Pump Upgrades
Installing a new fuel pump can be a straightforward process, but it requires attention to detail. Here are some tips to ensure a successful installation:
- Safety First: Always disconnect the battery and relieve fuel system pressure before starting the installation.
- Follow Instructions: Refer to the manufacturer’s instructions for specific installation steps.
- Check Fuel Lines: Inspect and replace any damaged fuel lines during the installation.
- Test for Leaks: After installation, check for any fuel leaks before starting the engine.
Tuning Your Engine After Fuel Pump Upgrade
Once you have upgraded your fuel pump, it’s essential to tune your engine to take full advantage of the increased fuel delivery. This can involve adjusting the air-fuel ratio, ignition timing, and boost levels. Here are some tips for tuning:
- Use a Wideband O2 Sensor: This tool helps monitor the air-fuel ratio accurately during tuning.
- Adjust Fuel Maps: Modify the fuel maps in your engine management system to ensure optimal performance.
- Monitor Performance: Keep an eye on engine performance and make adjustments as necessary.
- Consult Professionals: If unsure, consider hiring a professional tuner for optimal results.
Conclusion
Upgrading your fuel pump is a crucial step in unlocking the full potential of your turbocharged car. With the right fuel pump and proper tuning, achieving an increase of 70+ horsepower becomes an attainable goal. By investing in quality parts and following best practices for installation and tuning, you can enhance your vehicle’s performance and enjoy the thrill of driving a more powerful car.
