All-New, Powerful, Low-Cost Version-6 Engine Simulation!
View Comparison Of Engine Simulation Features

DynoSim6 is a completely new engine simulation from Motion Software, Inc.
   DynoSim6 is not only an upgrade from our previous DynoSim5, it has been completely rewritten from the ground up to include wave-dynamics tuning aspects from our professional simulation Dynomation-6.
   DynoSim6 not only has better accuracy and many new features, it still is very easy to use! How can this be? Our Direct-Click™ interface lets you select any engine component on the left side of the screen, change any specs, then view the simulation results on the right! It‘s so intuitive, you‘ll be building horsepower with DynoSim6 in just minutes!
   DynoSim6 includes three wave-dynamic displays that let you “see inside” your running engine! You can determine, at a glance, intake and exhaust pressures, charge flow, and of course Power, Torque, VE, Airflow, Valve Lift, and much more! The new displays let you locate and minimize intake reversion, correct miss-timed exhaust pulses, locate flow restrictions, and more. DynoSim6 will help you understand why your engine makes power and show you where you need to focus your efforts to improve performance.
   DynoSim6 also includes advanced forced-induction modeling. Add turbochargers, Roots/screw and centrifugal superchargers with a mouse click. Set boost, belt ratios, turbine sizes, A/R ratios, even model intercoolers.
   Our all-new DynoSim6 engine simulation is powerful step forward in technology (was in development for 10 years!). Put it to work for you, and get the most from your next engine build. Get started with these simulation extras (included for a limited time): 6000+ Camfiles and 3500+ Lobe Profile Files (a $130 value). You‘ll find even more engine, flow, and camfiles on the Internet (the DynoSim Series of engine simulations have over one hundred thousand of users worldwide). DynoSim6 also comes with a 300+ page, easy to understand, color user manual (view on screen from within the program). Bottom Line: DynoSim6 is, simply, the best simulation for the money, and it’s fun to use, too!

Software Details: DynoSim6 reveals (otherwise invisible) pressure waves and mass flow in cylinders and engine passages. It 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!
DynoSim6 is remarkably easy to use. All engine components and specifications are clearly visible. Change components simply by clicking on any Direct-Click™ menu. DynoSim6 is intuitive and encourages you to “play” and test new ideas! With DynoSim6 you’ll quickly optimize performance in any engine!

   DynoSim6 allows anyone to easily and intuitively explore the effects of cam-timing, intake manifolds, mufflers and exhaust systems, fuels, nitrous, supercharges, and much more. Motion engine simulations help you understand IC (internal combustion) mass flow and how it affects performance. DynoSim6 displays internal pressures and flows and let‘s you quickly change components and specs to optimize cylinder filling. Easy-to-read graphs and tables give you an unprecedented insight into why specific changes alter power and torque.

DynoSim6 lets you build a virtually unlimited range of engines, from humble single-cylinder engines to exotic V-16 racing powerplants. Design, build, and test a 1700hp ProStock engines, passenger-car daily drivers, Sport-Compact engines with Variable-Valve-Timing, or motorcycle engines! 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! DynoSim6 will not only meet, but exceed, your engine simulation expectations!

User Interface And Features: Despite the extensive modeling power, DynoSim6 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 DynoSim6, you can view charge reversion, in-tune and out-of-tune conditions, and examine how cam timing affects mass flow. Because DynoSim6 has been so carefully crafted for ease of use (see our Feature-Focus: New Roll-Up Menus), it is an excellent educational tool on engine pressure-wave dynamics! And this fact is no better exemplified by the 3D, real-time rendered, cutaway engine that can be displayed within the program.

Mass Flow Visualization: DynoSim6 includes a 3D cutaway engine with piston, valve 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, watch the engine move through its cycles, visualize mass flow, exhaust and intake pressure waves, flow velocities, and more! The 3D engine graphic in DynoSim6 helps you understand the relationship between crank-angle graphs and actual engine flow.

Technical Overview: Surprisingly, DynoSim6 includes a great deal more than this. You’ll also find hundreds of other features including: 1) rapid Iterative™ testing [see below], 2) a comprehensive CamManager™ tool, 3) import CamPro, CamProPlus, S96, and CamDoctor profile cam files, also model and import 10-point cam files (for a limited time, DynoSim6 comes with a comprehensive library of 6000+ camfiles and 3500+ profile files), plus import cylinder-head-flow and engine files, 3) the simulation includes several built-in calculators for compression ratio, airflow conversion, rocker-arm math, cam-timing math, 4) you can run multiple-engine simulations at once, then perform side-by-side, and One-Click QuickComparisons™, 5) print professional multi-page ProPrint™ dyno-test reports, and more. You are probably beginning to see why we say DynoSim6 is the most accurate, capable, and complete engine simulation software package ever offered to engine enthusiast for less than $150.00.

Unique Motion Software Features: In addition to advanced simulation technology, here are some additional features in DynoSim-6 that were designed and developed by Motion Software, Inc., and are unique to our simulations:

Users Manual: DynoSim6 is supplied with a 300+page, full-color, on-disk Users Manual (directly accessible from within the simulation) and a printed 16-page QuickStart guide that will get you going fast. You can download a copy of the Users Manual to review the capabilities of this software before you buy (a download link is provided at the top of this page).
