The DynoSim™ is an all-new, state-of-the-art engine simulation for Windows95/98/Me or Windows2000/XP from the experts at ProRacingSim, LLC., Software (check out customer comments). Designed for you, the performance enthusiast, DynoSim has unmatched power to find the best component combinations for any engine project. Build domestic or sport compact, street or racing engines with an easy-to-use Windows interface. Select from a wide range of components, fuels, forced induction, and even test any cylinderhead airflow. Super-fast simulation routines combined with a breakthrough Iterative Testing™, makes DynoSim the most powerful, most comprehensive, and most fun engine dyno simulation on the market.

Software Overview: DynoSim incorporates new technology that helps you find optimum component combinations for any engine application faster and easier than ever before. Using our new QuickIterator™, click one button and the DynoSim will "home in" on the best parts combination for you, automatically! Run hundreds, thousands, or even millions of tests! The QuickIterator™ will perform all the testing, keep track of all the results, and display the best combination for you to review.

DynoSim also incorporates new simulation models that allow you build an even wider range of engines for street or racing applications (see below). Analyze turbochargers, centrifugal blowers, and roots superchargers. More manifolds, camshafts, cylinderheads, extended bore and stroke ranges, and more.

Nitrous-Oxide Injection can be used with gasoline to add horsepower boosts from 0 to 400+hp. The DynoSim can be used to evaluate the safe levels of Nitrous flow vs. power by displaying cylinder pressures (Bmep) throughout the rpm range. Use this information to determine how a nitrous system should work before you hit the button!

User Interface And Features: DynoSim has a completely new user interface custom built from the ground-up for Windows95/98/Me and Windows2000/XP. Our eye-popping “XP” look is even easier to use with QuickAccess™ buttons and DirectClick™ menus that let you change parts simply by clicking on any component shown on screen. Nothing could be easier! Analyze engine performance using a wide range of full-color graphics (ProTools™ includes color DataZones™ that add even more graphing capability). All data and graphs can be printed (and previewed) in color on any Windows printer. You can even model several engines at once; just click on any Engine Selection Tab to further analyze any engine design.

Select several ways to view and study Power, Torque, Manifold Pressure, Cylinder Pressures, and more. Auto-scaling graphs and numeric listings of vital statistics are just a mouse click away. The DynoSim also includes enhanced versions of three powerful, built-in calculators: The Cam Math QuickCalculator, The Compression-Ratio Calculator, and The Air Flow Calculator. Each of these easy-to-use dialogs allows you to easily convert and manipulate cam specs, cylinderhead flow-bench data, and even determine the effects of changes to combustion-chamber volume, dome heights, gasket thicknesses, and more. Never before has so much calculation power been available for such a reasonable price.

New CamManager™: A powerful new feature in the DynoSim, the CamManager™ lets you see a cam timing dynamically change as you change cam specs. Modify every cam timing variable independently, and test the results instantly. Use the search capabilities of the CamManger™ to find CamFiles that match your designs, Search through 800+ CamFiles in less than a minute (on most systems)! Expand this capability to over 4000 camfiles with the CamDataSim™. Find any timing value, recommendation specification, manufacturer, engine family, and more. The CamManager™ is a fun-to-use tool that adds tremendous testing capability to the DynoSim.

New ProTools™ Kit: While all essential features are included in the Advanced version of the DynoSim, professional engine builders and serious enthusiasts need all the modeling power they can get. The optional ProTools™ Kit extends the functionality of many DynoSim features. It includes shorter stroke and smaller bore modeling, the ProIterator™ for fully customizable testing, DataZones™ to give you the most graphing and data analysis power possible, ProData™ that includes a new table of extended engine data, and ProPrinting™ that prints out a comprehensive dyno test report that can include your name, address, company logo, glossaries, and all ProData™ values. If you're serious about engine analysis, consider a ProTools™ addition to the DynoSim.

Technical Overview: Here's how the DynoSim works: The simulation calculates the gas dynamic, thermodynamic, and frictional physics of virtually any 4-cycle internal-combustion engine. Horsepower is determined from an analysis and integration of cylinder pressures from 2000 to 11,000rpm. All basic engine components and specifications are accurately modeled, including bore, stroke, 1-to-12 cylinders, a wide range of cylinderheads and port configurations, valve sizes, compression ratios, naturally-aspirated and forced-induction systems, airflow, exhaust systems, and virtually any camshaft timing or valve lift. American and Metric units are supported, and conversion between unit systems is fast and easy. ProTools™ allows viewing, graphing, and printing "technical" engine data, including engine pressures, power loss from friction, volumetric efficiency, and manifold vacuum at each power point within the dyno test. Use this data to gain deeper insight into engine operation and efficiency.

Users Manual: The DynoSim is supplied with a 140-page, full-color, on-disk Users Manual (directly accessible from within the DynoSim) that details the features of this comprehensive engine simulation.
