Engine/turbo flow mapping .xls

[silencer.1]

I've made this from a compelation of formulas and previous programs. It's pretty accurate on overall flow but still makes a few assumtions so it's definately not perfect.

It outputs cubic feet per minute airflow, corrected cubic feet per minute airflow, lbs/min air flow, corrected lbs/min air flow, corrected cubic meters per second air flow (for all those japanese flow charts) and an estimated horsepower output.
