Engine Builder

Engine Builder is an easy to use static and dynamic compression ratio calculator for almost any engine type. Dynamic compression ratio is calculated based on camshaft intake-closing point and connecting-rod length. The App also helps you calculate engine displacement, deck-height, rod/stroke ratio, unit conversion and much more. Includes data for common engines so you don’t have to go out the app to look for the most basic data. Supports both metric and standard measurement units. Compression ratio calculations can be easily saved to avoid entering data over and over again.
