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. Review: great resource, - I'm an engine builder/head porter with approximately 30 years of experience. I bought the book because I trust the information give by the author, Harold Bettes. After reading the book I found the approach of giving many different references for formulas to be a sensible way of helping to narrow specifics used for development. The book was well written and had an easy to use method for describing not only the math but also what the numbers used in equations represent. I realize that it would be difficult at best for any author to write all the years of experience that Mr. Bettes has in just one book. I feel that he did a great job to cover as much as he could, touching on current issues that engine builders are faced with without loosing focus on the basics . After reading the book, I found that it would be helpful to both experienced and unexperienced gearheads. The book is a great read, and should be found in the library of all respected head porters and engine builders. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003QHZMG6 | | Accessibility | Learn more | | Best Sellers Rank | #1,646,972 in Kindle Store ( See Top 100 in Kindle Store ) #121 in Automotive Customization #312 in Automotive Repair (Kindle Store) #524 in Automotive Engine Mechanics | | Customer Reviews | 4.6 4.6 out of 5 stars (130) | | Enhanced typesetting | Enabled | | File size | 15.9 MB | | ISBN-13 | 978-1101188583 | | Language | English | | Page Flip | Enabled | | Print length | 162 pages | | Publication date | June 30, 2010 | | Publisher | HP Books | | Reading age | 18 years and up | | Screen Reader | Supported | | Word Wise | Not Enabled | | X-Ray | Not Enabled | ## Images ![Engine Airflow HP1537: A Practical Guide to Airflow Theory, Parts Testing, Flow Bench Testing and Analyzing Data to Increase Performance for Any Street or Racing Engine - Image 1](https://m.media-amazon.com/images/I/91WOYjQL0VL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant! *by T***J on July 25, 2011* Great book and is chocked full of useful formulas and references for later use.

Harold's well paced effort to make mortals understand the basic elements of air flow is remarkably enthralling. The reader does not need to read between the lines to understand the theories and formulas. "Engine Air Flow" is definitely a keeper for the professional and amateur engine builder. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/110661581-engine-airflow-hp1537-a-practical-guide-to-airflow-theory-parts](https://www.desertcart.it/products/110661581-engine-airflow-hp1537-a-practical-guide-to-airflow-theory-parts) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-13*
