Message: [QUOTE="KCTurbos, post: 1434821, member: 13852"] Exactly. You have to make a lot of educated guesses about Compressor efficiency and then work backwards. Then you need to know the VE of your motor? That is always a best guess. air/Fuel ratio? Intercooler efficiency? Pressure drop across the intercooler? Baro? Outside temp? Then you need to know what your Boost is at certain rpms. Once you get your guesstimate flow rate then need to calculate your pressure ratio and plot ONE POINT. To see what your truck is actually doing you would have to plot a bunch of points and see where it falls on the compressor map. Even after all that you are playing guess and check to see where the truck falls on the graph. [/QUOTE]
