The chart shows pump sizes versus maximum horsepower output for carb supply systems, for pumps in good condition. The Chart uses 0.5 Brake Specific Fuel Consumption (BSFC) for gasoline and 1.1 BSFC for methanol. The pumps are driven at 1/2 crank speed, oper- ate at a maximum of 50 PSI, and have 20% of the volume bypassed back to the fuel tank. SELECTING THE CORRECT PUMP MECHANICAL PUMP SUPPLYING CARBURETOR SYSTEM, WITH NITROUS OXIDE The mechanical pump MUST be capable of supplying the required volume at the RPM the nitrous is engaged. Just because the pump is large enough to feed the engine at 7000 RPM with nitrous, DOES NOT mean it is big enough to supply the volume of fuel at 3500-4000 RPM with nitrous. When engaging the nitrous at low RPM, a larger pump will be required to get the volume needed. DO NOT CONFUSE VOLUME WITH PRESSURE. There may be plenty of pressure before the nitrous is engaged, but when the enrichment solenoid opens and starts to flow volume the pressure will immediately drop.
