PROPERLY SELECTING ELECTRONIC FUEL INJECTION COMPONENTS

One of the more commonly misunderstood aspects of Electronic Fuel Injection (EFI) is how to select the correct size fuel injectors, fuel pump and Mass Air
Flow (MAF) sensor for a particular engine horsepower output. The following information is intended to offer a very brief tutorial on properly selecting the most
common EFI components.

FUEL INJECTORS

First and foremost, adding larger fuel injectors alone will NOT create extra horsepower! The purchase of larger fuel
injectors should only be considered when your engine has exceeded the horsepower capacity of the existing fuel
injectors, at which point larger injectors are then required to SUPPORT the additional horsepower. If you add larger-
than-stock injectors to an otherwise stock engine, you should not expect any horsepower increase whatsoever.

The nominal injection pressure for most Ford EFI systems is 39.15 psi (270 kPa) “across the injector.” The term “across the injector” takes manifold pressure
and fuel rail pressure into account, and is usually referred to as “delta pressure.” (See “Measuring Fuel Pressure” below for more details.) Ford Racing’s fuel
injectors are always rated at 39.15 psi delta, so the fuel injector sizing discussions found below will assume a fuel pressure of at least 39.15 psi delta.

The Bosch Green top 558 is a highly efficient fuel injector that incorporates a straight stream fuel delivery.Best used in engines with single-intake valves.

Application:Crossflow Volkswagen/VW 8v and VR6 12V aka

4 cylinder 8V and MK2/3 VR6 engines with a single intake valve per cyl.

(You will need two more injectors for VR6 obviously)

Some turbo Volvo cars

Big turbo VW/Audi 1.8t motors can use these injectors with excellent results
