Here is expert practical advice from an experienced race engine builder on how to build an ignition system that delivers maximum power reliably. With the enormous amount of inaccurate information about ignition systems and the confusing choice of expensive aftermarket parts out there, which all claim to deliver more power, there's a need to get the real scoop. Des Hammill cuts through the myth and hyperbole and tells readers what really works, so that they can build an excellent system without wasting money on parts and systems that simply don't deliver.
Ignition timing and advance curves for modified engines is another minefield for the inexperienced, but Des uses his expert knowledge to tell readers how to optimize the ignition timing of any high-performance engine. 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).
