Engine Factory is now offering this new Retrotek Boss EFI System on its Ford and Chevy V8 crate engines. It is the first major leap in technology for aftermarket fuel injection systems and by far the least expensive and the easiest system to install. The fuel injection system features the Engine Management System (EMS) mounted directly on the throttle body. This eliminates a major portion of the wiring harness found on most EFI systems. The injectors, and the idle air control are contained inside the throttle body and the unit that controls them is attached to the side of the throttle body. Despite its compact size, the EMS is still laptop programmable although this is normally not required with most installations. It’s a feature for those enthusiasts who prefer to do their own programming. For most enthusiasts, the installed program is more than suitable.This, like their other EFI systems, is fully self learning. Install it, fire it up, drive it around for 30 minutes or so and it dials itself in. It continues to fine tune itself as it adjusts to your driving habits and various atmospheric conditions.
If your vehicle already has a return line, or you want to install one, you can eliminate the
added cost of the Returnless Kit. And if your vehicle has both a return line and a high-pressure EFI-style fuel pump, you do not need either of the optional kits.If your vehicle does not have a return line to the fuel tank, the simplest installation of all is to select the basic kit along with the Returnless Kit. The main advantage of this system is simpler installation and fewer wires cluttering up your engine compartment.
The listed kits are all rated up to 500 horsepower. Higher horsepower engines will require larger injectors and a bigger fuel pump. For details contact Engine Factory, www.fordcobraengines.com.
