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.

Welcome to a series of great, down-to-earth and practical testing techniques you can carry out on the road without having to spend a lot of money. Test the flow of airboxes, airfilters, cat converters and mufflers. Aerodynamically test your car and improve the flow through intercoolers and into airboxes. Analyse handling, turbo response, cam timing changes and engine management tuning changes. And not only can you test the results of your modifications, you can also make measurements that will show you which modifications are likely to be the most effective on your car. This is a book that should be on the shelf of every car modifier.

DIY Testing of Car Modifications: How to test aerodynamics, flow test intake & exhaust systems, assess performance improvements, and measure actual ... all without spending more than $50.

Do you want to be able to fit and tune programmable engine management, working from home? You can! This book covers the selection, wiring and tuning of programmable ECUs, all done without access to a dyno and with a totally hands-on approach. From the step-by-step of tuning idle, throttle enrichment and high- and low-loads, to tuning for best fuel economy. Mapping exhaust gas recirculation for better throttle response, to safely retarding ignition timing with increased intake air temps. PID tuning loops explained in easy to understand language, directly measuring the crank reference indicator position, and how Lambda numbers relate to air/fuel ratios - they're all here. And if you’re just starting out in this area, there’s also coverage of the fundamentals of engine management systems. There’s even a cheap and incredibly effective tool that you can build so that you can hear when the engine is detonating – or even close to detonating. This compact book is must-have for anyone tuning programmable ECUs.

This unique book takes a completely different approach to do-it-yourself suspension development. First it gives you the theory - in an easy to understand way, non-mathematical way. Then it gives you the practice - the tin-tacks of applying that theory to get excellent results.The theory includes the natural frequencies of sprung masses, the relationship between static deflection and natural frequency, and how you can use your smart phone to directly measure bounce, pitch and roll frequencies of your car's suspension.Also covered are real and virtual swing-arms, roll centres, and the relationship between roll centre, centre of gravity and body roll. Damping - its function and the two fundamental types - also gets a look-in.After the theory, it's time for the practice. Three major case studies are used. The first case study involves designing and building from scratch the air suspension for an ultra-light-weight 3-wheel vehicle... in fact, a vehicle that in total weighed under 20kg. The design decisions were about having sufficient suspension travel, achieving zero bump steer, and having effective roll stiffness.... all with very low weight.Then covered is a front wheel drive car, with special emphasis on the design selection of custom springs that provided the correct front/rear stiffness and ride height change. Next is a traditional rear-wheel drive car. In this case, the decision was made to use one company's complete suspension kit for this model - new springs, dampers, anti-roll bars, and revised rear axle location. Step-by-step pictures show the complete fitting sequence.Finally, one-off suspension changes are covered - adding a front camber kit, fitting a rear anti-roll bar on a front-wheel drive, and - more complexly - altering the front/rear torque split in an electronically-controlled all-wheel drive car.Whether you're just starting an interest in suspension, or would like to better understand the theory, this book is a must-have for every car enthusiast.Chapter headings:      Introduction             Springs and natural frequencies           Spring and wheel rates  Measuring wheel rates   Natural frequencies in pitch and roll    Measuring ride quality  Damping theory               Suspension geometries Front-end angles            Describing handling     Bump steer       Handling solutions quick guide   Developing the suspension for a human-powered vehicle              Selecting new springs for a front-wheel drive suspension upgrade            Fitting a full suspension kit to a rear-wheel drive car       Fitting a MacPherson strut camber kit     Custom suspension bushes         Modifying electronic car handling systems            User-adjustable stability control                 Developing a torque split controller

This book will show you how to write strong and effective arguments of the sort used in government, private business and non-government organisations.  It is practical, down to earth and easy to understand. It is not a study of logic, or premises, or all those other things you always seem to find in books on writing arguments! Instead, it uses easy-to-remember rules that you can employ in all documents, large or small.  Many people write rather muddled arguments that are difficult to follow and often do not result in the outcome intended by the author. So if you can write clear, precise and well-articulated arguments, you will have a strategic advantage in any workplace.  With this book, you can achieve just that.
