Typical factors affecting Volumetric Efficiency (imperfect filling):
Intake valve restriction
Intake valve closing timing
Trapped residuals
Induction system restrictions



Volumetric Efficiency Calibration Checklist


Using the preliminary WAVE run (pre-calibration) results, perform the following:

Compare volumetric efficiency vs. rpm against measured data

Compare plenum pressure vs. rpm and vs. mass flow against measured data

Compare back pressure vs. rpm and mass flow against measured data
