Vehicle Aerodynamics - Testing, Modification & Development: For road, racing and alternative transport
Modify the aerodynamics of your road or race car for better performance.
• Reduce drag and lift with proven modifications.
• Improve airflow through radiators, intercoolers and oil coolers.
• Measure the effectiveness of undertrays, wings and spoilers.
• Understand the latest advances in car aerodynamics.
• Use practical and low-cost aero testing techniques you'll find nowhere else.
• Read the views of professional car aerodynamicists from Porsche, Tesla, Rivian, Jaguar and Rover.
• Authoritative, deeply researched and practical.
• 500 pages and 800 colour photos, diagrams and charts.
The one resource you need if you're modifying or developing vehicle aerodynamics.
"This book puts into the hands of both enthusiasts and professionals an easy to understand, yet technically rigorous, guide to developing and modifying car aerodynamics. Highly recommended." - Rob Palin, former Tesla lead aerodynamicist
"This shows just what can be achieved without using a wind tunnel or professional level CFD. A very impressive book." - Dr Jeff Howell, former head of aerodynamics at Rover and Jaguar Land Rover
"Clearly explained concepts, useful and effective test techniques and plenty of example modifications and measurements - this book has everything a home modifier needs to implement successful aerodynamic changes to their own car." - Jon Young, amateuraerodynamics.com
Note from the
So why is it so expensive? Four reasons. First, Amazon has just lifted their printing costs, due no doubt to worldwide inflation. Second, the book is full colour (i.e. full colour on every page), which adds significantly to printing costs but also makes diagrams, graphs and photographs so much easier to understand. Third, at 500 pages, well over 800 images and 11 x 8.5 x 1.2 inches thick, it’s a large book. Finally, in the context of car modifications – and potentially getting them wrong and so wasting time and money – it’s a cheap investment.
So why no Kindle version? Three reasons. First, any electronic version of a book is immediately pirated. I am not greedy, but I do need some financial recompense for my work. Second, the biggest danger I find with the topic of car aero modification and development is that people look at only a small part of the whole, get the wrong idea and then go off and do bad modifications. With a physical book they are much more likely to leaf through more material, so getting a much better contextual understanding. Finally, I love books. I have a very extensive library and to me, a physical book has so much more to offer than just words and images on a screen.

About the author
Julian Edgar
45 books4 followersJulian Edgar, 56, started his working life freelancing for photography magazines. He then worked as a secondary school teacher for eight years before leaving teaching and becoming a full-time technical writer.
He edited a national Australian automotive print magazine before becoming editor of an online car magazine. Along the way he wrote extensively for electronics hobbyist magazines while also contributing articles to publications in Australia, the UK and the US.
He has also worked at Executive Level in the Australian Public Service. Formal qualifications include a Diploma in Teaching (Secondary), Bachelor of Education and Graduate Diploma in Journalism.
In the automotive field he has owned cars with two, three, four, five, six and eight cylinder engines; diesel, petrol and hybrid petrol/electric drivelines; front-wheel drive, rear-wheel drive and all-wheel drive configurations; and cars with single turbos, twin turbos and superchargers.
He has been electronically modifying his cars for about 30 years. Over that time he has modified engine management systems, engine cooling systems, turbo boost controls, electric power steering systems, auto transmission controls, all-wheel drive torque split controls, stability controls, hybrid car regenerative braking controls, and lighting and sound systems.
He also enjoys aerodynamic modification of cars. He was the first automotive journalist to extensively wool tuft cars and write about the results (starting in 1989), and use Magnehelic gauges to directly measure aerodynamic pressures (in 2000) - both approaches now widely used by amateurs. In 2018 he developed a technique allowing amateurs to measure car aerodynamic panel pressures on the road.
Julian has supercharged - and then turbocharged - a Toyota Prius. He has also turbocharged a Honda Insight and fitted it with programmable engine management, doing the engine mapping from scratch. The Insight also has electronically-controlled, custom air suspension that Julian developed and fitted.
He has an extensive home workshop that is equipped with a chassis dyno; lathe; mill; MIG, TIG and oxy welding gear; metal folder and other tools.
Julian lives in a hamlet 80 kilometres north of Canberra, Australia. He is married to Georgina and they have a son, Alexander, who is 16 years old. Also in the family are Victor the sheep and Ar-Chee the cat!

Proud to be the first reviewer! Thorough book with great examples: I now have an intuitive (if rudimentary) understanding of vehicle aerodynamics.
