Flow calculator

What size injectors do I need? Selecting the proper fuel injector size is critical for performance along with ease of tuning/mapping. To calculate your required flow rate use the flow calculator below. Number of cylinders - Fuel BASE pressure pressure (your fuel pressure at idle) - Engine aspiration - Horsepower - Maximum injector duty cycle (IDC %) we recommend a maximum of 90%.
