Ten years have passed since the original edition of this book was published, but Alfa Romeo enthusiasts everywhere are more active today than ever in preserving, modifying and racing these excellent cars. Throughout this time, the author in true Alfista fashion, never stopped looking for and trying new techniques to increase the power, overall performance and reliability of Alfas and their engines. This book is the result of much research, and also first-hand experience gained through many Alfa rear wheel drive model projects, from the 105 series to the last of the 75 models. There is a lot of completely new information regarding TwinSpark Cylinder head mods, big-brake mods, LSD adjustment procedure, electrical system improvements, plus many flow-bench diagrams, dyno plots, and much more.
