units on the map. what is the pressure unit on the Y-axis? (p2c/p1c)
The x-axis is lb/hr. How do I convert that to cubic feet per minute (CFM)?
*I'm guessing to figure out an engine's CFM needs you'll need a flow bench.

Is that your reply? Why bother, unless you're Mr. Bell's publisher. I plan to pick up the book...eventually. Maybe google will offer more insight. sheesh.

Understood. I first thought you were being flippant, but I can see that some of this requires lenghty explanations (like Jesse stated). No sense in rewriting a book. I'll pick up a copy per suggestion. thanks.

so the turbo FS-DE guys are looking at
8psi / 9.1cr = 0.879
is a VE of 85% reasonable?
anybody use this website: http://www.turbofast.com.au/tfcalc.html
*BTW, I'm getting THE BOOK in April.........
