Holley EFI 441cc fuel injector for tuning, turbo engines and motorsport applications where more fuel capacity is required than with standard injectors. The injector is suitable for setups where the engine has been upgraded with a turbo, increased air mass, higher boost pressure or different engine management.
This injector has a flow capacity of 441cc and, at 3 bar fuel pressure, can be calculated for up to approximately 58 horsepower per injector on petrol. The figures are indicative and based on turbo engines with approximately 90% duty cycle.
It is often used for VAG 1.8T engines where approximately 300-350 horsepower is desired. For higher power targets, a 4 bar fuel pressure regulator can in some setups allow approximately 350-400 horsepower, depending on turbo, engine management, duty cycle and fuel system.
The injector has a Bosch/Amp-style connector, high impedance and is supplied with O-rings. It is designed for 12V saturated driver type and fits setups where dimensions, connector type and injector flow match the engine’s requirements.
