There is an introduction called Beetle power - a look back at the origins of the VW engine by Edward Eves. Street, custom, kit car, off-road, or full-race, this book gives you all the air-cooled engine-building basics to find and put to the pavement hidden horsepower. Includes tips on carburetion, ignition and exhaust tuning, case beefing, cylinder-head flow work, camshaft selection, lubrication and cooling upgrades, 6-to 12-volt conversions and much more. Plus there's a natty 6-page history of the origins of the first air-cooled VW engines. Double or triple the output of your air-cooled Volkswagen.
