Using Computers To Build Horsepower
We are pleased to announce that the DeskTop Dynos book has become an "official" best-seller. It recently outsold all other automotive performance books.

Overview: The 128-page DeskTop Dynos book was written especially for the automotive enthusiast (check out customer comments). The result of two years of research, this easy-to-read guide contains a completely unique look at high-performance engines: A view from the perspective of the simulation designer. While most engine builders and enthusiasts developed their skills from years of hands-on tinkering, the background of the simulation expert is thermodynamics, wave dynamics, and the physics of motion. Each of these "camps" have their own insight into how engines work, however, the exchange of knowledge between academia and the engine shop has been almost non-existent. It's been non-existent, that is, until now!

DeskTop Dynos explains how many of the "mysteries" of the internal-combustion engine can be understood using wave dynamics and other simulation techniques (for an excerpt, click here). Without resorting to complex math or physics, DeskTop Dynos clearly shows WHY the dimensions of internal engine passages are the key to unlocking more horsepower. You'll discover why most camshaft timing specs are simply advertising "hype" instead of useful descriptions of camshaft function. You'll find out how bore and stroke affect pumping work and how that can add and subtract power. But most importantly, DeskTop Dynos will show you WHY it is virtually impossible to predict power changes from most combinations of components without simulating the complex physics at work within the engine. No engine expert on earth can analyze the interactions of pressure, heat, and mass flow within an engine and accurately predict the outcome. But that's exactly what engine simulation software does in just minutes! DeskTop Dynos will give you new insight into how this process works and the knowledge to use this technique to build more horsepower into any engine.

Technical: 128 page, 8-3/8 x 10-7/8 soft-bound. DeskTop Dynos contains hundreds of photos and detailed drawings. ISBN 1-884089-23-2. Copyright (C) 1996-2002 by Motion Software, Inc. All rights reserved. Printed in USA.

Availability: The DeskTop Dynos "Big Book" is available directly from Motion Software. See How To Purchase The DeskTop Dyno Book below (and don't miss our special Web offer). This quality technical book is a "must-have" for any performance enthusiast.
