Modern Power Management: EFI Systems and Components for Pontiacs at Butler Performance

The Benefits of Upgrading to EFI

The main appeal of EFI for a classic Pontiac is the ability to achieve self-tuning capability. Unlike a carburetor that must be manually adjusted for altitude, temperature, and specific performance parts, modern EFI systems use wideband O2 sensors to constantly monitor and adjust the air/fuel ratio. This results in:

• Instant Starting and Smooth Idles: Excellent cold and hot start performance, regardless of weather.

• Optimized Fuel Economy: Precisely metered fuel delivery based on the engine's exact needs.

   

• Peak Performance: The system always maintains the optimal air/fuel ratio for maximum horsepower and torque output.

   

Featured EFI Systems and Solutions

Butler Performance organizes its EFI offerings into easily digestible categories, ensuring a fit for every builder and budget.

1. Butler Complete EFI Solutions

This is Butler Performance's premiere offering, providing a full, turn-key system specifically assembled and matched for a Pontiac engine.

• Matched Components: These packages include the main ECU/Throttle Body unit, high-quality fuel pumps (often Aeromotive or Holley), necessary fuel lines and regulators, and specialized accessories.

• Proven Performance: By using pre-matched kits, the customer avoids compatibility issues and can be assured the system will integrate seamlessly with their Butler-built engine.

2. Holley EFI Systems

Holley is a powerhouse in EFI technology, offering systems that cater to a wide range of performance needs:

• Holley Sniper EFI: A highly popular, self-tuning throttle body injection (TBI) system that bolts onto a conventional 4-barrel intake manifold, making it an easy swap from a carburetor.

   

• Terminator X & Dominator Systems: These are multi-port injection (MPI) systems designed for maximum tunability, sequential injection, and control over ignition timing, ideal for high-horsepower or boosted applications.

3. FiTech EFI Systems

FiTech is known for offering robust and value-driven EFI systems, making the leap to fuel injection more accessible.

• Go EFI 4, 8, and 2-Barrels: Offering self-learning systems that are simple to install and come with integrated fuel pressure regulators.

   

• FiTech Tri-Power EFI Systems: A specialized and visually stunning option that maintains the look of a classic three-carburetor setup while offering the modern efficiency and tuning of EFI.

4. Multi-Port and F.A.S.T. Systems

For custom engine builders and racers, the flexibility of multi-port injection (where each cylinder has its own injector) is essential.

• F.A.S.T. EFI SYSTEMS: Offering high-level, advanced engine control systems and components for builders who need total control over every engine parameter.

Essential EFI Components and Accessories

Beyond the main unit, a successful EFI conversion requires a robust fuel delivery system, which Butler Performance provides:

• Fuel System Upgrades: Including high-flow in-tank or external fuel pumps, high-pressure fuel filters, and regulators designed to handle the 40-60+ PSI required by EFI (versus the typical 6-8 PSI for a carburetor).

• Sensors and Wiring: Offering quality oxygen sensors, harnesses, and specialized hardware necessary for the system to collect data and make real-time adjustments.

By providing expertly curated EFI systems and the essential accompanying components, Butler Performance helps Pontiac enthusiasts bring modern precision, reliability, and power to their classic muscle cars.
