Optimising Car Performance Modifications is a highly practical and useful book that covers brilliant techniques to take the guesswork out of performance modification.Using just some lowcost tools, you can easily measure the flow restriction of your car's intake and exhaust. It's like having a huge flowbench always available. By making some simple onroad 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 lowcost app and a smartphone, you can accurately measure suspension behaviour.If you want a practical, handson 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.
