## Fuel Injector Flow Rate Calc Description
Building a turbo setup or swapping injectors and need to know if your fuel system can keep up? This calculator tells you exactly what flow rate each injector needs based on your target horsepower — so you never run lean under boost.

Enter target HP, cylinder count, BSFC, and duty cycle to get required flow per injector in lb/hr and cc/min. Supports gasoline, E85, diesel, and methanol with automatic BSFC defaults. Includes fuel pressure correction factor for non-standard rail pressures.

FEATURES:
- Required injector flow per cylinder in lb/hr and cc/min
- Fuel pressure correction factor calculator
- Gasoline, E85, diesel, and methanol support
- Automatic BSFC defaults per fuel type
- 1 to 16 cylinder configurations
- Duty cycle input for safe injector headroom

Essential tool for engine tuners, fuel system builders, and performance shop technicians. Works offline.
