There isn't enough information on the sheet to know the exact flow . A few missing numbers are , Temperature , and the test pressure . Typically the test pressure is 28" , but some flow benches won't pull that depression, so lower depressions are used then scaled to 28" for comparison . Temperature is used to create a correction factor, and there maybe other things that I am forgetting that contribute to that correction . So the best you can do with your sheet is to multiply each test point by the percentage and create a graph of Lift vs. Flow , for the Intake and Exhaust . So as an Example for the Intake , you would multiply 400 x 70% = 280 cfm .
