Amateur Car Aerodynamics Sourcebook by Julian Edgar Pdf

At last - a book for those who like to modify the aerodynamics of their road cars!In this book author Julian Edgar explores a host of practical and low-cost techniques that you can do yourself without spending a lot of money or needing special facilities. Section 1 introduces aerodynamic drag and lift. The language is simple and straightforward - but still includes concepts such as drag co-efficients, lift co-efficients and the different types of drag that affect road cars. Section 2 is devoted to aerodynamic testing - directly measuring aerodynamic pressures, and seeing airflow patterns by the use of on-road wool-tuft testing. Section 3, the largest part in the book, covers aerodynamic modification. Fitting vortex generators, testing different undertrays, reducing drag, using turning vanes in intercooler ducting - all are covered in detail. In addition, techniques are described for reducing wind noise, building an effective engine intake that breathes high-pressure cold air, siting bonnet vents in the correct location, and testing airflow through intercoolers. With nearly 300 full-colour photos and diagrams, this book is practical and down to earth - and uses techniques able to be carried out on the road.

Thoughts about Driving, Car Modification and Life... . by Julian Edgar Pdf

Author Julian Edgar spent over a decade writing new car tests and, very unusually for a motoring journalist, also modifying his own cars and writing about those modifications. Here are his thoughts on topics as diverse as whether a dyno is a good place to develop car modifications, the joys of left-foot braking, whether people who choose to buy thirsty cars should then complain about the price of fuel, and what it's like when the throttle jams fully open. Over 50 topics are covered - from a scathing criticism of those who choose to waste away their lives, to how it's impossible to have a favourite car maker, from science not being a social panacea, to optimising turbo boost control for power and economy. Every page is provocative, thought-provoking, challenging and interesting!

Modifying the Aerodynamics of Your Road Car by Julian Edgar Pdf

This unique handbook assumes no starting knowledge of vehicle aerodynamics. It begins with simple ideas and finishes with sophisticated and effective aerodynamic modifications that work. Three major chapters cover on-road testing techniques that give you all the information you need to decide what modifications you should make – and, after you’ve made them, how well they work. Low-cost techniques allow you to visualise the patterns of airflow over your car so that you can actually see the problem areas that need improvement. Uniquely, you’re also shown how to measure aerodynamic pressures, so you can determine which body surfaces are creating lift, drag and downforce. Want to work out where a wing should be placed? On-road testing to find that out is covered as well. The book also shows you how to measure downforce to see if that wing is actually working! If you wish to reduce drag, more than ten different areas are covered. Reducing frontal area, lowering cooling system drag, optimising vehicle ride height and rake, reducing the strength of the wake, achieving clean airflow separation and optimising wheel designs – they’re all covered using the latest research findings. And if you’re a performance driver, there’s a major chapter devoted to reducing lift and improving stability. This chapter includes the design and development of undertrays and diffusers, wings and spoilers. The example car developed measurable downforce when fitted with an undertray and rear diffuser, something that transformed its on-road handling. The author has been writing about the aerodynamics of road cars for more than 25 years. He is also an experienced and proficient car modifier who has performed numerous aerodynamic modifications and upgrades to his own cars. The book’s technical consultant, RH Barnard, is an acknowledged world leading automotive aerodynamicist. If you want a practical, hands-on guide that demystifies and explains car aerodynamics, and shows you how to make effective aerodynamic modifications to your car, this book is for you.

Optimising Car Performance Modifications by Julian Edgar Pdf

This highly practical and useful book covers brilliant techniques that take the guesswork out of performance modification. Using just some low-cost tools, you can easily measure the flow restriction of your car’s intake and exhaust. It’s like having a huge flow-bench always available. By making some simple on-road measurements, you can plot the shape of the engine’s power and torque curves – no dyno needed. This allows you to not only see if performance modifications to the engine are improving power, but also see where in the rev range those changes are occurring. Assess the worth of cams, a larger turbo, changed boost control or altered engine management mapping. But the book doesn’t stop there – it also shows you how to measure your car’s aerodynamics, seeing if at speed your car is developing lift or downforce. Want to make a rear wing work well? Test the angle at which downforce is greatest. You can also test the aerodynamic airflow through oil coolers, intercoolers and radiators. Interested in improving your suspension? By using a low-cost app and a smartphone, you can accurately measure suspension behaviour. If you want a practical, hands-on book that will immediately save you money, show where modifications are most needed, and can be used to assess performance outcomes, this is the book for you. The author is an enthusiastic hands-on modifier who performs all work on his cars himself in his home workshop. He has been testing car modifications on his own road cars for more than 25 years.

A Century of Car Aerodynamics by Julian Edgar Pdf

Covering every decade from the 1920s until now, this book reveals an incredible array of fascinating and advanced aerodynamic designs - cars shaped to cheat the wind or stick to the road. Meet an automotive inventor so weird he'd taken a vow of silence and had to communicate by writing notes... discover one of the lowest-drag cooling systems ever used in a production car... and see how the science and art of car aerodynamics have progressed over the last 100 years. Written with the full cooperation of car aerodynamicists from Porsche, Tesla, General Motors and Volkswagen, the coverage is detailed and accurate. Over 60 individual cars are described - from the tiny Fiat Uno to the mighty Bluebird Land Speed Record car. Learn about wings and spoilers, the Kamm tail and how today's low-drag electric cars are being developed. Be amazed that some cars built over 80 years ago have better aerodynamic figures than many current cars. See rare concept cars from Mercedes, Ford and Chrysler. Researched on three continents and containing more than 450 photos, diagrams and graphs, this book will forever change how you view car aerodynamics. "Someone once said that to know where you are going you need to know where you have come from. Julian Edgar's new book provides car aerodynamicists with a vivid and detailed understanding of how we got here over the past 100 years." Jeff Howell, Visiting Professor Loughborough University and former head of Aerodynamics at Rover, Jaguar Land Rover and Tata Motors European Technical Centre.
