Message	of MAS voltage since we know now how much CFM maps to each MAS voltage reading, will it be possible to determine the ideal exhaust diameter size? If you know the CFM going into the motor, know the VE of the motor, in theory could one determine the exhuast size needed to adequately support the setup of the particular car tested ? Would you / could you flow test the exhaust to determine the limitations or max flow rate ( assuming that you had a broad range of different systems ) and then match the exhaust system based on the VE of the car setup and the MAS voltage / CFM ???
