Measuring VE

[gte861v at prism.gatech.edu]

Would it be possible to measure the Volumetric Efficiency on an engine using a 
correctly calibrated MAF sensor?  I have been pondering this idea.  I have an 
engine dyno on which to do the measuring and a wind tunnel and the appropriate 
hardware to accurately calibrate a MAF sensor so why couldn't I measue the VE 
of the engine? All that I would have to do is at a certain RPM measure the air 
flow, calculate what it should be based on that displacement at that RPM and do 
the percentage.  Is there something I have forgotten or could this be a 
valuable way to accurately set my VE tables.  Thanks,
