Air flow??
Is there an equation to convert airflow grams/second into cfm. My car maxes out at 208 g/s at 4800 rpm. Just wondering what is normal in terms an old guy can relate to.

I would really like to know whats normal. I'd like to make the most of my scanning and there is a lot to learn. IF someone gave the weight of one cubic foot of air (in grams) I think I could do the math.

Spanky...
take the Lbs /min reading multiply by 14....
i.e. 32 lbs/min *14 = 448 CFM
a "rough rule of thumb.. it takes about 1.5 CFM to make 1 horsepower.
CFM /1.5 + extimated HP 298.66 HP
Hope this helps
