Un-stroked vs Stroked Displacement vs. Crank Angle, etc.

It's a good read and it sounds like you would get some from it. The book goes into a lot about head flow and interpreting results. It's heady... but at least it's not a veru long book...lol. Also if you don't have it, Larry Meaux's Pipemax os a great excel-based program to play with, and inexpensive to buy.
