315cc petrol injector for tuning and upgrading fuel systems. The injector is suitable for petrol engines with increased fuel requirements and is often used on applications such as Audi 1.8T and VW Golf 4 1.8 Turbo.
This injector has a flow capacity of 315cc and, at 3 bar fuel pressure, can be calculated for up to approximately 41 horsepower per injector on petrol. The figures are indicative and based on turbo engines with approximately 90% duty cycle.
With 4 injectors and a 4 bar fuel pressure regulator, they can deliver up to approximately 296 horsepower on a 1.8T engine, depending on setup, fuel pressure, duty cycle and the engine’s other components.
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.
