Software Overview: Setting new standards in simulation technology, Dynomation allows users to look inside a running engine! Dynomation lets you see and analyze the powerful wave dynamics controlling induction and exhaust flow. For the first time, anyone can explore the effects of runner lengths, port taper angles, header tubing and collector dimensions, cam timing interactions, and much more. No other device or computer program does a better job of helping you understand internal mass flow. Dynomation displays precisely how pressures and flow velocities vary at the valve/chamber interface. View induction and exhaust pressure pluses and mass flow data to gain unprecedented insight into why specific changes alter power and torque.

And Dynomation applies this tremendous modeling capability to a virtually unlimited range of engines, from humble single-cylinder engines to exotic V-12 racing powerplants. Design, build, and test a 1600hp ProStock engines, passenger-car daily drivers, exotic Sport-Compact Variable-Valve-Timing racers, or motorcycle engines (even those with megaphone exhaust systems)! With nearly one thousand built in shortblock configurations, a wide variety of domestic and import induction systems, hundreds of forced-induction choices, and much more, Dynomation will become your most valuable development tool.

User Interface And Features: Despite the awesome modeling power in Dynomation, this simulation package was carefully designed to be easy and intuitive to use, even for beginners exploring engine dynamics for the first time! Are we exaggerating? Not at all. Supplied with an easy-to-read 300 page Users Manual, any user can learn how finite-amplitude waves (over 10,000 times "louder" than the typical sound waves we hear every day) move, change, and flow within the engine. By simply "playing" with Dynomation, you can easily see charge reversion, in-tune and out-of-tune conditions in the intake and exhaust passages, how cam timing affects mass flow and much more. Because Dynomation has been so carefully crafted to be easy to use, it is the best educational tool on engine pressure-wave dynamics available anywhere, hands down! And this fact is no better exemplified by the 3D realtime-rendered, cutaway engine available within Dynomation.

Dynomation includes a 3D cutaway engine with piston motion and gas-dynamic flow rendered in real-time and synchronized with the wave-dynamics, crank-angle results graphs. Simply, drag the graph pointer and watch the engine move through its cycles, visualizing mass flow, exhaust and intake pressure waves, flow velocities, and more throughout the entire 4-cycle process! With the 3D engine, Dynomation helps you see WHY an engine makes more power or, perhaps even more importantly, uncover and fix the reasons for poor performance.

Technical Overview: Everything about this new simulation is groundbreaking. Dynomation incorporates two distinct engine simulation models: 1) A Filling-And-Emptying simulation that provides extremely fast mathematical solutions to engine physics, including flow analysis and common intake- and exhaust-manifold modeling, making this technique a uniquely powerful and rapid way to "ballpark" engine design with very good accuracy, and 2) A full Wave-Dynamics Method-Of-Characteristics simulation that accurately predicts the complex pressure-wave dynamics and particle flow in intake and exhaust ducting. The Wave-Action model picks up where the Filling-And-Emptying method leaves off and "homes in" on the best port sizes, shapes, runner lengths, header-tubing sizes, cam timing and valve motion, and much more, providing unprecedented accuracy for the serious engine designer and builder.

By integrating these simulation technologies using a carefully-crafted Direct-Click user interface, engine data is seamlessly shared by both simulation models. Power, torque, engine pressures and more can be displayed independently, in comparison views, or in a HybridSim (a ProTools feature), where simulation results from both methods are intelligently combined, building on the strengths of each modeling technology.

The complete Dynomation package includes a great deal more than this. You ll also find hundreds of other features that have become ProRacing Sim s trademarks, including: 1) rapid Iterative testing, 2) comprehensive CamManager camshaft, cylinder-head-flow and engine-file import, 3) several built-in calculators for compression ratio, airflow conversion, and cam-timing math, 4) multiple-engine analysis, side-by-side, and One-Click QuickComparisons , 5) professional multi-page dyno-test reports, and much more. This is the most accurate, capable, and extensive engine simulation software package ever offered to the professional or engine enthusiast.

ProTools Features: If you are a serious enthusiast, racer, or professional engine builder, you will find the additional tools and features supplied in ProTools Kit a valuable addition to the Advanced Mode of Dynomation. Here is a quick overview of key ProTools Kit contents (view the Engine Simulation Feature Table for a comprehensive overview of program features):

ProIterator A powerful feature of the ProTools Kit. The ProIterator retains all the simplicity and ease-of-use of the Quick Iterator (supplied in the Advanced Mode), while adding powerful testing and analysis capability, including custom ranges, Induction-system Iteration, analysis of areas under the power and torque curves, and much more.

DataZones Extends the graphic-display and data-analysis capabilities of Dynomation. Using this feature, you can add additional data to graphs and/or show ranges for target power values, clearly label dangerously high pressures, engine speeds, and more. To view DataZones displays, see page 203.

Additional Simulation Data And Analysis ProTools adds additional simulated pressures, forces, and other data to the graphs and tables in Dynomation. The additional data includes: Indicated Horsepower, Frictional Horsepower, Pumping Horsepower, Mechanical Efficiency, Gas Force On Piston, Induction Airflow, and Piston Speed. In addition, port-flow mass analysis data is provided and can be graphed or viewed on the 3D engine cutaway. Pressure waves are visible in the ports of the 3D engine and are keyed to the Crank-Angle graph reticules.

Import FlowPro, CamProPlus, S96, CamDoctor Files ProTools adds the capability to import FlowPro flow bench files and a number of cam Profile files. A comprehensive import dialog allows you to set the lift for duration calculations, centerlines, etc.

ProPrinting Turns simulation results into a comprehensive "presentation" report of dyno-test data. ProPrinting features include custom graphics, a cover page with the name and address of your business (or your personal name and address) and logo, a table of contents, optional text printed at the bottom of each page (can be a disclaimer, copyright notice or any other text you wish), optional comprehensive or "mini" glossaries, and a complete listing of all test data and results at each rpm test point, including additional engine-data values, pressures, forces, and more not included in a Advanced Version.

Users Manual: Dynomation is supplied with a 300-page, full-color, on-disk Users Manual (directly accessible from within the Dynomation) and printed QuickStart guide that details the features of this comprehensive engine simulation.

What s New For Previous DOS Users: If you have used the earlier, DOS version of Dynomation (originally developed by Curtis Leaverton at V.P. Engineering) you will find the ProRacing Sim Dynomation Adavnced release to be a very substantial upgrade (even more so with the addition of the ProTools Kit; see description, above). Many aspects of this program have been rebuilt from the ground up, including the user interface, results displays, sophisticated Forced-Induction modeling, plus the incorporation of a super-fast Filling-And-Emptying simulation that can rapidly "ball-park" engine designs. In addition, you find an enormous speed increase in Wave-Action analysis!
The display and analysis of pressure waves in the intake and exhaust ports also has been greatly improved. Simply click on the power/torque graph to select any rpm point, and you will instantly see the status of pressure waves and mass flow. Drag the reticule line on the power/torque graph, this will dynamically display the pressure waves as engine speed changes. This capability provides an unprecedented view of pressure and particle flow within a "running" engine.
Another new addition to Dynomation Advanced is a powerful, but easy-to-use Iterative Testing feature for the Filling-And-Emptying model. An exclusive feature of ProRacing Sim simulations, Iterative Testing allows you to automatically perform thousands of dyno tests, keep track of all the results, and locate the best component combination that matches your search criterion. This is a great way to locate nearly optimum cam timing that can be fine-tuned in the Wave-Action model!
In addition to these major enhancements, you will find hundreds of other improvements, including additional menu selections, more airflow and camfiles, a substantially expanded users manual, and an optional ProTools Kit , and much more!
