After all, as the computer science term says, “Garbage In, Garbage Out.” What that means, is that if you haphazardly enter parameters, you’re going to get a poor result. The most critical part of setting up a simulation is, well, the set-up.

“But you can learn a ton of useful information from these engine software packages.” “There are some assumptions that have to be made about thermal efficiency, windage, friction and dozens of other small factors, such that I prefer to use a dyno for horsepower comparisons,” says Godbold.

Per the DynoSim5 manual, the DynoSim software performs several million calculations at each 500-rpm test point, with 41 test points calculated in a full power curve simulation. By being “full-cycle” simulations, they calculate the complete fluid-dynamic, thermodynamic, and frictional conditions that exist inside each cylinder throughout the entire 720 degrees of the four-cycle process.Ĭonversely, other software relies strictly on calculations to determine volumetric efficiency alone, and then estimates horsepower and torque from that. The software utilizes the “Filling and Emptying” mathematical models for both their accuracy and fast processing times. Also needed is a CD-ROM drive, which is important to mention, as today’s line of netbook computers meet the system requirements otherwise, but don’t have an onboard CD-ROM.

For reference, we ran our copy on a two-year-old Windows 10 machine with a 6th Gen Core i7 processor, with 12 GB of RAM, and found zero lag in the program. Obviously, the faster your processor is, the better the program will perform when running the complex calculations required. The system requirements might have been considered exceedingly robust many years ago, but these days, almost any machine capable of running a modern version of Windows, will be more than capable of running the software. The DynoSim5 program is a 32-bit program designed for Windows operating systems. So, we are curious to see what would happen in an even-displacement comparison, theoretical though it may be.įirst, let’s get the technical stuff out of the way. Many of the critics of that comparison have pointed out that the LS and Coyote were not on an even playing field, displacement-wise. To that end, in this article, we are going to take an in-depth look at the software and its features, then model two real-world engines and compare their performances on the dyno to their simulated performances in the program.įor the final act, we’re going to model a 5.0-liter Coyote engine, and compare it to a hypothetical 5.0-liter LS engine, using the rules established in our previous LS-Coyote Shootout series.

“I think it is perfect for small engine builders, or more professional guys that need to get in the ballpark quick on engines they do not build often,” says Billy Godbold, Comp Cams’ Valvetrain Engineering Group Manager. With a decade and a half of refinement, DynoSim5 has become a valuable tool in the arsenal of both high-end performance enthusiasts and engine builders alike.īy allowing testing of a wide range of components and specifications, without buying a single component or turning a single wrench, the engine simulation software allows you to save money and dyno time by being able to concentrate only on the areas which have shown promise in the simulation. Fifteen years ago, ProRacing Sim released the first version of its software, the original DynoSim.Īt present, we are up to version 5 of the engine modelling software, with version 6 in the works. The company ProRacing Sim, LLC-now a division of the Comp Performance Group-saw the need for an accessible engine simulation software. How many reasons do you need to use a specialist? King XP-Series main bearings deliver consistent and reliable performance with a high-load capacity, and the prognosis from the specialists is a long and happy life for your engine.Ever since home-based personal computers have become a thing, companies have looked for ways to harness that computing power for more than games like Minesweeper and Solitaire. 0001 in.!
