EFI, Alpha-N vs Speed Density fueling Strategies

MAF sensors do a very good job of measuring airflow but their weakness in a race application is that they are only accurate over a very narrow range so it would take a sensor/housing designed specifically for the application. In the case of stock and super stock, we are flowing much more air than a stock engine therefore we have moved out of their effective range. Also, since these classes are throttle body limited, anything in the airstream before the throttle body is undesirable. In stock or modified street vehicles, Mass Air systems do a great job. They just have no place in this type of racing in my opinion.
