Great book and is chocked full of useful formulas and references for later use. I was hoping for an advanced book on airflow and not just another silly book scratching the surface with port volumes, exhaust scavenging, and the like and this book nailed it. They literally have about 2 chapters talking about flow benches and different methods for measuring airflow and not just assuming you have the ability to magically get any specific port flow numbers you want without having to do any measuring. They are assuming you ARE building an engine from scratch and not only go over ways to calculate numbers which are relevant to your interests, but how to go about quantifying those numbers. Long story short: If you're just doing plug and play work on engines (swapping heads, exhausts, intakes, etc.) this book is probably more than you need. If you're building engines from scratch and need critical flow numbers for a specialized class of racing you need this book.
I know the type of racing I do you need to be an expert on every measurable characteristic on the engine you've built otherwise you're not going to be competitive and will get eaten alive in design judging.
This informative, fully illustrated handbook includes basic discussion on the science of engine airflow and relationships, how flowbenches work, testing individual engine components, how to analyze the data, calibration issues, intake and exhaust tuning, engine formulas, and putting it all together for maximum performance.
