Turbocharging Normally Aspirated Engines on a Budget is a clear and detailed book that explains a method to turbocharge any engine - so the average gearhead can design a system that will be both reliable and low cost at the same time. This explains how to make custom turbocharger installations for any car, not bolt-on kits. Includes Toyota, GM, Dodge, and Mazda examples, tested and proven by Autocross racing experience, which can be copied directly or used as a roadmap to turbocharge other engines. Topics include eliminating spark knock, calculating horsepower, selecting turbocharger, CE (Compressor Efficiency), MAP, MAF, fuel injectors, upgrading the fuel system, intercoolers, and more. Written by an engineer. Includes detailed wiring diagrams, graphs, tables, formulas, and plenty of photographs. An Excel spreadsheet (for calculating turbocharger performance) described in the book can be downloaded from the author at WagonerEngineering.com.
