### Motorsport Fuel Injectors & Accessories — Flow, Duty Cycle & BSFC Calculator (https://hvelectronics.co.nz/collections/injectors-accessories)
- Summary: Injector flow scales with the square root of differential fuel pressure across the nozzle: Flow_new = Flow_rated × √(ΔP_new / ΔP_rated). To prevent solenoid overheating and non-linear ball/pintle bounce, maximum effective injector duty cycle should not exceed 80–85% at peak RPM.
- Key Specs: Bosch EV14 1000cc (0 280 158 040): 980 cc/min @ 3.0 Bar · 12.0 Ω High-Z (Dead-Time: 0.92 ms @ 14.0V); Bosch EV14 1500cc Motorsport: 1,500 cc/min @ 3.0 Bar · 9.1 Ω High-Z (Dead-Time: 1.05 ms @ 14.0V); Bosch EV14 2200cc Racing: 2,200 cc/min @ 3.0 Bar · 9.1 Ω High-Z (Dead-Time: 1.18 ms @ 14.0V)

### Motorsport Fuel System Components — Bosch 200 Pump, Regulators & Line Sizing (https://hvelectronics.co.nz/collections/fuel-system-components)
- Summary: In a 1:1 manifold-referenced fuel system, fuel rail pressure tracks intake manifold pressure (P_rail = P_base + P_boost) so differential injector pressure remains constant. However, the fuel pump must overcome the total combined pressure (e.g., 3.0 Bar base + 2.0 Bar boost = 5.0 Bar pump head), reducing pump flow.
- Key Specs: Bosch 200 External Pump: 275 L/h @ 3 Bar · 235 L/h @ 5 Bar ($200.60 NZD (2022 Archive)); AN-6 PTFE Braided Line: 8.7 mm (0.34") Inner Diameter (Supports up to ~650 HP on E85); AN-8 PTFE Braided Line: 11.1 mm (0.44") Inner Diameter (Supports up to ~1,100 HP on E85); 10-Micron Stainless Filter: Post-Pump High-Pressure Filtration (< 0.08 Bar Pressure Drop)
