Using Computers To Build Horsepower Videos

In 1993, early versions of Dynomation™ became widely recognized by professional engine builders and racers as the World's leading engine simulation software, combining robust modeling with unprecedented ease of use. After nearly 20 years of successful application and millions of dollars of further development Dynomation-5™ is now available to engine professionals, automotive engineers, and any serious enthusiast of 4-stroke engines.

Automatic Updating: Dynomation-5 users steadily receive FREE updates that add powerful new features to this amazing engine simulation. As a Dynomation-5 user, you will benefit from continued software development by our dedicated engineering staff. Updates are distributed automatically over the Internet and insure that your simulation will use the latest technology and include many new features requested by our loyal users. Find out more about Motion's Automatic Update policy.

Software Overview: Dynomation-5 lets you peer inside a running engine! It reveals (otherwise invisible) pressure waves and mass flow in cylinders and engine passages. Dynomation-5 will accurately display how much power an engine will produce, but it will also show you why it makes that power and where you should put your efforts to optimize performance (see the Feature-Focus: Dynomation-5 Charge-Flow Analysis)!
Although Dynomation-5 is well known for high accuracy and technical detail, it is remarkably easy to use. All engine components and specifications are clearly visible. Change components simply by clicking on any Direct-Click™ menu. Dynomation-5 is intuitive and nearly effortless to use; it encourages you to “play.” With Dynomation-5 you’ll quickly zero-in on the best combination of components to optimize power in any engine!

Dynomation-5 allows anyone to easily and intuitively explore the effects of runner lengths, port taper-angles, header and collector dimensions, cam-timing interactions, and much more. No other device or computer program does a better job of helping you understand IC (internal combustion) mass flow and how it affects engine performance. Dynomation-5 displays precisely how pressures and flow velocities vary at the valve/chamber interface. Easy-to-read graphs and tables give you an unprecedented insight into why specific changes alter power and torque.

Dynomation-5 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, Sport-Compact engines with Variable-Valve-Timing, 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-5 will not only meet your engine simulation needs, it will become your most valuable development tool!

User Interface And Features: Despite the awesome modeling power in Dynomation-5, this engine simulation was built from the ground-up to be intuitive and easy to use, even for beginners exploring engine dynamics for the first time! Are we exaggerating? Not at all. Supplied with a clear 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" in Dynomation-5, 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. Because Dynomation-5 has been so carefully crafted for ease of use (see our Feature-Focus: New Roll-Up Menus), it is the best educational tool on engine pressure-wave dynamics available anywhere, hands down! And this fact is no better exemplified by then 3D real-time rendered, cutaway engine that can be displayed within Dynomation-5.

Mass Flow Visualization: Dynomation-5 includes a 3D cutaway engine with piston motion and gas-dynamic flow rendered in real-time and synchronized with the crank-angle results graphs. Simply drag the graph pointer through the 720-degrees of the 4-Cycle process, and watch the engine move through its cycles, visualizing mass flow, exhaust and intake pressure waves, flow velocities, and more! The 3D engine in Dynomation-5 helps you see the relationship between crank-angle graphs and actual engine flow.

Technical Overview: Dynomation-5 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 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, valve motion, and much more, providing unprecedented accuracy for the serious engine designer and builder.

By integrating these simulation technologies, engine data is seamlessly shared by both simulation models. Power, torque, engine pressures and other simulation results can be displayed independently, in comparison views, or in a HybridSim™, where simulation results from both methods are intelligently combined, building on the strengths of each modeling technology.

The complete Dynomation-5 package includes a great deal more than this. You’ll also find hundreds of other features including: 1) rapid Iterative™ testing [explained below], 2) a comprehensive CamManager™ tool, 3) import CamPro, CamProPlus, S96, and CamDoctor profile cam files, also model and import 10-point cam files (Dynomation-5 comes with a comprehensive library of 6000+ camfiles), plus import cylinder-head-flow and engine files, 3) several built-in calculators for compression ratio, airflow conversion, rocker-arm math, cam-timing math, 4) multiple-engine analysis, side-by-side, and One-Click QuickComparisons™, 5) professional multi-page ProPrinting dyno-test reports, and more. This is the most accurate, capable, and complete engine simulation software package ever offered to the professional engine builder or avid enthusiast.

Unique Motion Software Features: In addition to our advanced simulation technology, here are some additional features in Dynomation-5 that were designed and developed by Motion Software, Inc., and are unique to our simulations:

  • Fuel- And Charge-Flow Analysis (added with Update 5.09) lets you see and modify Intake Reversion, Charge Lost To Exhaust, Exhaust Spoilage Flow, and much more (see our Feature-Focus: Dynomation-5 Charge-Flow Analysis).

We REALLY LISTEN to our users requests for new features and additional modeling capabilities. Over 100 updates have already been sent to Dynomation-5 users for FREE! Can you afford to use outdated software? That's never an issue with Dyomation-5.
  • Iterator™—The QuickIterator™ and ProIterator™ testing tools add powerful automated testing and analysis capability for cam, induction, and other component selections. A few mouse clicks and Motion's Iterator™ will "home in" on the best parts combination for you, automatically! Run hundreds, thousands, or even millions of tests! The Iterator™ will perform all data analysis, keep track of all the results, and display the best combinations based on your testing criterion.
  • DataZones™—Extends the graphic-display and data-analysis capabilities of Dynomation-5. Using this feature, you can add additional data to graphs and/or show ranges for target power values, clearly label high pressures, engine speeds, and more.
  • ProPrinting™—Turns simulation results into a comprehensive "presentation" report of complete 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, optional 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, graphs, tables, and more. Give your customer a ProPrint  report of the simulated engine you plan to build, and you'll make an impression guaranteed to build your business!
