MECHANICAL FUEL PUMP FOR MFI Mechanical fuel injection uses a positive displacement fuel pump to load the jetting distribution system. Proper fuel pump size and jetting is vital for good performance and good spark plug readings. In the past, Hilborn fuel pumps were rated by the manufacturer at 1,800 RPM fuel pump speed. Enderle, […]
Racing mechanical fuel injection jetting is made up of nozzles to the engine and one or more bypass pathways back to the fuel supply. The positive displacement fuel pump with the jetting layout makes a linear ‘fuel curve’ with engine RPM. That is, the fuel to the engine per revolution is essentially constant. As RPM […]
Our 5000 Horsepower on Methanol tech manual features specs on some very high output methanol racing engines. A 6,000 horsepower combination is detailed on p. 132. It is based on a top fuel drag racing V-8 long block with two stage compressors. A minimum fuel pomp size is 32 GPM at 4000 pump RPM. Boost […]
