The G72 Twin Turbo engine is a popular choice among performance enthusiasts looking to push their vehicles beyond the 400 horsepower mark. To achieve this level of performance, upgrading the fuel system is essential. In this article, we will explore the necessary injector and pump upgrades that can help you maximize the potential of your G72 Twin Turbo.
Understanding the Fuel System
The fuel system in any vehicle is crucial for delivering the right amount of fuel to the engine. In a high-performance setup like the G72 Twin Turbo, the stock fuel system may not be sufficient to meet the demands of increased horsepower. Upgrades are necessary to ensure optimal performance and reliability.
Why Upgrade Fuel Injectors?
Fuel injectors play a vital role in the performance of your engine. They are responsible for atomizing fuel and delivering it to the combustion chamber. When upgrading to a G72 Twin Turbo setup, higher flow injectors are needed to provide the necessary fuel for increased power output.
Benefits of Upgrading Fuel Injectors
- Improved fuel atomization for better combustion
- Increased fuel flow to support higher horsepower
- Enhanced throttle response
- Better tuning capabilities
Choosing the Right Fuel Injectors
When selecting fuel injectors for your G72 Twin Turbo, it’s important to consider the flow rate. Typically, injectors in the range of 750cc to 1000cc are recommended for setups aiming for 400+ horsepower. Additionally, the type of injector, whether it’s high impedance or low impedance, can also affect performance.
Popular Injector Options
- Injector Dynamics ID1050X
- DeatschWerks DW750
- Fuel Injector Clinic 1000cc
The Role of Fuel Pumps
In addition to upgrading injectors, the fuel pump is another critical component that requires attention. A higher flow fuel pump ensures that the engine receives a steady supply of fuel, especially under high-load conditions. Stock pumps may not be able to keep up with the demands of a twin-turbo setup.
Choosing the Right Fuel Pump
For a G72 Twin Turbo aiming for over 400 horsepower, a fuel pump capable of delivering at least 255 liters per hour (LPH) is recommended. This ensures that even at maximum power, the engine receives adequate fuel without starvation.
Top Fuel Pump Recommendations
- Walbro 255LPH Fuel Pump
- DeatschWerks DW300
- Radium Engineering Fuel Pump
Installation Considerations
When upgrading your fuel system, proper installation is crucial. It’s recommended to consult with a professional or follow detailed guides to ensure everything is set up correctly. Pay attention to the wiring, fuel lines, and any necessary modifications to the fuel tank or fuel rail.
Tuning Your G72 Twin Turbo
After installing new injectors and pumps, tuning is necessary to optimize performance. A professional tune will adjust the air-fuel ratio, ignition timing, and other parameters to ensure your engine runs efficiently and safely at higher power levels.
Conclusion
Upgrading the fuel system in your G72 Twin Turbo is essential for achieving over 400 horsepower. By selecting the right injectors and fuel pumps, and ensuring proper installation and tuning, you can unlock the full potential of your engine. With these upgrades, you’ll enjoy improved performance, reliability, and driving excitement.
