Book excerpt: Nitrous oxide's incredible horsepower-per-dollar value makes it one of the most popular ways to boost engine performance. Done improperly, though, this “cheap” thrill can come at a steep price; the information in this book might make all the difference between having a blast with nitrous and having a real blast—and leaving expensive engine parts strewn all over the road. This handbook explains how nitrous oxide works, and how to make it work for you. The author, an expert on the subject, gives clear, step-by-step instructions for installing and using a successful nitrous system in either carbureted or fuel-injected, computerized cars—from preparing your engine for nitrous oxide applications to tuning it for maximum performance and safe operation. He also tracks some more advanced nitrous tuning techniques through test data and case studies. His book is the ultimate resource for anyone who wants to cheaply, safely, and wildly boost horsepower at the push of a button.
