Book Description: This text provides expert practical advice, from an experienced race engine builder, on how to build an ignition system that delivers maximum power reliability. Cutting through the myth and hyperbole, Des Hammill tells the reader what really works so that they can build a system without wasting money on parts and systems that simply don't deliver. The text also discusses ignition timing and advanced curves for modified engines. The book applies to all four-stroke gasoline/petrol engines with distributor-type ignition systems, including those using electronic ignition modules. It does not cover engines controlled by ECUs (electronic control units).
