Upgrading the Fuel System for High-boost Procharger Setups: Recommended Injectors and Pumps

by

When it comes to maximizing performance in high-boost Procharger setups, upgrading the fuel system is essential. The right injectors and fuel pumps can make a significant difference in power delivery and engine reliability. In this article, we will explore the best options for injectors and fuel pumps to support your high-boost Procharger system.

Understanding Fuel Requirements

High-boost applications demand more fuel to maintain the optimal air-fuel ratio. This ensures that your engine runs efficiently and avoids issues like detonation. To determine the right components, consider the following factors:

  • Engine size and configuration
  • Boost levels intended
  • Fuel type being used
  • Power goals

Selecting the right fuel injectors is crucial for high-boost setups. Here are some top recommendations:

  • Injector Dynamics ID1050X: Known for its high flow rate and excellent atomization, making it ideal for boosted applications.
  • DeatschWerks DW400: Offers a great balance of performance and reliability, suitable for high horsepower builds.
  • Bosch EV14 750cc: A popular choice for many tuners, providing consistent performance and durability.
  • Siemens Deka 80lb: These injectors are well-regarded for their high flow rates and reliability in demanding conditions.

Injector Sizing

When sizing your injectors, it’s essential to calculate the necessary flow rate based on your power goals. A common formula to estimate the required flow rate is:

  • Power (HP) = (Flow Rate (lb/hr) * 0.5) / (Air-Fuel Ratio)

For example, if you aim for 600 horsepower with an air-fuel ratio of 11.5:1, you would need approximately 60 lb/hr injectors. Always round up to ensure you have enough fuel delivery.

A reliable fuel pump is equally important in a high-boost setup. Here are some of the best options available:

  • Walbro 450 LPH: This pump is a favorite among enthusiasts for its high flow rate and affordability.
  • AEM 50-1200: Known for its reliability and performance, suitable for high horsepower applications.
  • DeatschWerks DW300: Offers a compact design with high flow capabilities, perfect for tight spaces.
  • Radium Engineering Dual Pump System: For serious power, this system allows for dual pump setups for maximum flow.

Fuel Pump Sizing

Just like injectors, fuel pumps need to be sized according to your power goals. A general rule of thumb is to choose a pump that can deliver at least 1.5 times the required fuel flow rate. This ensures that you have a sufficient fuel supply even under maximum load.

Fuel System Considerations

When upgrading your fuel system, keep these considerations in mind:

  • Fuel Lines: Ensure your fuel lines can handle the increased flow and pressure.
  • Fuel Pressure Regulator: A high-quality regulator is essential for maintaining consistent pressure.
  • Filters: Use high-flow fuel filters to keep debris out of your injectors and pump.
  • Wiring and Relays: Upgrade wiring to handle the increased current draw from high-performance pumps.

Installation Tips

Proper installation is key to ensuring your upgraded fuel system performs optimally. Here are some tips:

  • Follow manufacturer instructions for all components.
  • Use quality fittings and hoses to prevent leaks.
  • Check for proper alignment and secure all connections.
  • Test the system for leaks before starting the engine.

Conclusion

Upgrading the fuel system in a high-boost Procharger setup is a critical step in achieving your performance goals. By selecting the right injectors and fuel pumps, along with considering installation and system requirements, you can ensure your engine runs efficiently and reliably under boost. Always consult with a professional if you’re unsure about any aspect of your fuel system upgrade.
