Can you explain how to calculate the efficiency of a supercharger based on its design parameters? Hi guys, I desperately need help to find the equations to calculate the cfm with varying boost, can anyone assist me with this? To estimate the required carburetor CFM for your engine, input the engine displacement, maximum RPM, and volumetric efficiency. So if the supercharger pumps 850 cfm into the 450 cfm engine, the result will be a back pressure build up (boost). Roll your pointer to the left of the table to see typical values. Enter the RPM, the horsepower at this RPM & the engine capacity. An appropriately sized carburetor ensures that the right amount of air-fuel mixture reaches the engine, thus preventing issues like fuel This carburetor cfm calculator will help you to estimate the correct carburetor size for your engine.
