High-power supercharged motorcycles need to be matched with professional Fuel systems. Youdaoplaceholder0 the A340 Fuel Pump has an output flow of 380-1000 L/h (pressure adjustable from 43 to 95 psi) and is compatible with the engine power range of 200-750 kW. The original fuel pump of the Kawasaki H2 supercharged model only supports 300 kW. After modification, when the boost value reaches 1.8 bar, the required flow rate rises to 650 L/h. This pump can continuously supply a track pressure of 70±1.5 psi, avoiding the 17% flow rate attenuation that occurs under high-speed conditions. The actual measurement data of the 2023 SEMA Modification Show shows that the H2R matched with the A340 pump has improved the fuel injection pulse width stability to 98% at a full load of 12,000 rpm, and the air-fuel ratio fluctuation has been reduced to ±0.3.
The case of American cruiser fuel tank modification proves the compatibility advantage. Harley-davidson Street Glide uses the Aeromotive Stealth 340 built-in pump, with a flow rate of 400 L/h and a diameter of only 89 mm (3.5 inches), suitable for irregular fuel tank depths ranging from 120 to 180 mm. Compared with the original factory pump flow rate of 110 L/h, after modification, the fuel pressure of the 8.6L V-twin engine increased from 45 psi to 58 psi at 5,000 rpm, solving the common problem of insufficient fuel supply at 23% high speed in American motorcycles. The owner of the Indian Scout has measured a 12% reduction in fuel consumption, saving approximately 1,800 yuan in fuel costs annually, and extending the pump body’s lifespan to 7 years or 140,000 kilometers.
Competition-level sports bikes rely on precise pressure control. After the Suzuki GSX-R1000 was modified with a turbo kit, its power increased to 294 kW. The Aeromotive Eliminator pump combined with a PWM controller achieves a pressure fluctuation accuracy of ±0.5%. According to the FIM GT racing regulations, this scheme maintains a rail pressure of 85 psi under a 2.5 bar boost condition. The fuel injector activation response time is as fast as 0.15 ms (0.38 ms in the original factory system), eliminating acceleration lag. The 2022 Isle of Man TT race data shows that the Yamaha R1M equipped with this system has seen a 3.7% improvement in lap time and a 17 km/h increase in speed at the end of the straight.
The anti-reverse flow and thermal management technology of Ducati Panigale V4 can handle extreme working conditions. During frequent braking on track days, the fuel tank temperature can reach 60°C. Youdaoplaceholder0 The patented Hydramat oil rail expands the oil suction area by 380%, and in combination with the Teflon seal inside the oil pump, it can withstand a temperature of 140°C, ensuring continuous oil supply when the lateral acceleration is 1.5G. Actual measurements show that the flow rate of traditional pumps drops by 43% in a 30% oil level and high-temperature environment, while the flow rate attenuation of the A1000 model pump is only 9%, avoiding the 24% risk of flameout in curves. NHTSA recall analysis shows that the optimized Fuel Pump solution reduces the track accident rate by 90%.
The electrification modification requires A coordinated upgrade of the system. When the Zero SR/S is replaced with an extended-range engine, Aeromotive the Phantom 200 pump outputs a flow rate of 200 L/h at a low power consumption of 12V/15A, with a noise level as low as 45 dB (A). Its CAN bus interface supports integration with Motec ECU to achieve three-dimensional closed-loop control of flow, pressure and temperature, optimizing energy consumption by 18%. Industry reports indicate that this solution increases the WLTP range of hybrid motorcycles by 40 kilometers, shortens the charging cycle to twice a week, and reduces the payback period to 14 months. It is recommended to choose ISO 21434-certified products to ensure compliance with network security regulations.
