Looking to transplant a modern EFI engine into your classic muscle car, truck or hot rod? Leave that factory ECU and harness at the junkyard! The all-new Pro-Flo 4+ EFI management system offers simplified plug-and-play installation with untapped potential for calibration and diagnostics. Provides support for late-model Gen III/IV LS, Gen I/II Ford Coyote & Dodge Gen III HEMI engines with drive-by-wire throttle and variable camshaft timing (VCT) in hot rod transplant applications.
Pro-Flo 4 offers the ultimate in performance and power with the precise efficiency only a full sequential port EFI system can deliver. Full sequential port EFI systems delivers fuel into the intake air flow right at the port with an injector for each cylinder, allowing for better fuel atomization & distribution.
Browse through several EFI Fuel Systems, components andreplacement parts, to ensure your Edelbrock EFI System is always running top Notch. These Universal SumpFuel Kits are designed to provide the necessary high fuel pressure required for EFI applications in vehicles equipped with an existing low pressure carbureted fuel system.
Edelbrock throttle bodies are available in several sizes to deliver increased performance for a wide variety of applications. Smaller sizes are slightly larger than stock and are a great first step for stock or mildly modified engines. Larger sizes are for more radical, high-output engine combos and in most cases, require port matching of the manifold for proper fitment and performance.
Edelbrock Throttle Body Elbows are the best way to adapt LS1, LS2 and Ford 5.0L-based throttle bodies to EFI manifolds with traditional square-bore mounting pads. An internal divider optimizes flow quantity and distribution into the manifold and they can be mounted forward, backward, or sideways on Victor EFI square-bore manifolds.
Pro-Flo 4 Electronic Fuel Injection also gives you the ultimate control of your engine when using the Advanced Tuning features. These features give you the ability to easily adjust your ignition curve specifically for your engine setup, eliminating the hassle, complexity and limitations of the standard distributor advance mechanism. This type of control will result in a smoother idle, faster acceleration, better peak power, improved fuel economy and the ability to control detonation, all with the touch of your finger in the E-Tuner 4 app. The E-Tuner 4 App is available to download for Android and Apple iOS powered devices.
Throttle Body style EFI Systems feature fuel rails and injectors mounted directly to a throttle body. This design delivers the fuel into the air flow stream in the plenum similar to a carburetor. It’s the most universal type of Electronic Fuel Injection system, but it’s not ideal for high performance engines. Mixing fuel this way allows for it to puddle and condense in the plenum of the intake manifold, a recipe for hard cold starts. Another drawback is the delayed throttle response since the fuel must travel through the intake manifold to the combustion chamber. This can also cause the air/fuel mixture to separate as it flows to the cylinders, resulting in an uneven mixture between cylinders. Typically, the center cylinders run slightly richer than the outer cylinders, hindering tuning for peak fuel economy and peak performance. The OEM’s only utilized throttle body style injection for 9 years before transitioning to sequential port fuel injection for improved drivability and efficiency.
Pro-Flo 4 EFI Systems feature a high performance Edelbrock intake manifold with a 1,000 cfm throttle body, fuel rails and individual injectors for each cylinder. Key to the improved performance of a system like this is the fuel injector location, which is at the end of the runner on the intake manifold right before the air flow stream enters the combustion chamber. This location provides a more efficient mixture control thats unaffected by varying intake manifold runner temperatures and length. The fuel injector is also timed with the intake valve opening, giving the ultimate control and is the most efficient way to deliver fuel into your engine. This design produces the best fuel atomization and precise distribution to each cylinder for the ultimate performance.
