Engine Dyno Simulators
For the PC
Wouldn't it be cool to simulate what kind of horsepower and torque gains you'll get from various high performance engine parts before you put them on your vehicle? A variety of excellent software packages exist to simulate engines, and this page attempts to anaylize those that are currently available. All of the software packages listed below work on IBM compatible computers capable of running Win95 (Refer to supplier listings below for more specific information).

Why Use an Engine Dyno Simulator?

When most people rebuild their engine, they either do it to fix a tired powerplant or improve on their horsepower numbers. If improvements in horsepower and torque are sought, then it makes perfect sense to buy an engine dyno simulator for your computer. Not only will you be able to see what the heck all of those high performance camshaft specs can do to wake up your engine, but you can also simulate the motor and tweak it BEFORE its built. This will definitely help you get the most bang for your buck.

Listed below are a wide array of the companies that make engine dyno simulators for PC's. Included are ratings on each known software package and information on where to get these programs. If that isn't enough for you, check out They have three or four programs (Engine Shop, Engine Analyzer, Engine Analyzer Pro and Dynomation) that I have yet to review.

Desktop Dyno
Desktop Dyno is probably the most well known engine simulation software in the Hot Rodding world. It runs in MS-DOS but can simulate almost any engine combination imaginable from one to twelve cylinders. The benefit of having a program like Desktop Dyno is the sheer number of pre-programmed input variables and the print capability, which allows you to brag about the results you've simulated for your "real world" engine. This program actually calcuates values for horsepower and torque by using thermodynamic engineering formulas, which will ultimately lead to a better simulation when the numbers are crunched.

DYNO 2000

Desktop Dyno 2000 is the newest addition to the PC engine simulator market. Running under Win 95/98, this program interactively picks the best combination of parts and components to make the most power automatically! New simulation models allow for a wider range of engine choices and configurations. Pre-programmed parts include more intake manifolds and camshafts, while the program also allows the user to analyze superchargers, nitrous and alternate fuels. Data and graphical results can be printed for reference, and an array of 3D graphics enhances the screen output of the program.

Kris' Review: DYNO 2000
Image from program screen capture.
(*****) Five Stars. This is by far the finest engine dyno simulator I have ever used. After using this program to extensively model my LA-318 just after its most recent rebuild I must say that it is the best, most economical choice for novice to pro. What really made the program work so well for me was the ability to compare multiple camshafts in the same engine. To do this, I got specs from the Melling MTD-1 cam (as installed) along with two Mopar Performance cams, P4452757 and P4452759. Once the three simulations were created and properly setup, the six power and torque curves from all three cams could be combined on a single x-y plot (within the program) to evaluate which cam was the best compromise between horsepower and torque. It turns out that I should have picked the MP 4452757 cam, because its horsepower and torque curves were the best for the 0-5,000 rpm range as simulated.

Data from Desktop Dyno 2000

Dyno 2000 is actually programmed by the people at Motion Software. Along with this fine piece of software, they also offer the original Desktop Dyno program (they call it Dyno Shop), a Briggs & Stratton Raptor Engine Simulator and some great drag racing simulators. More Information:

HOT ROD Championship Drag Racing
Above: Kris' 318 Engine (rebuilt 5/99) Simulated in HOT ROD Championship Drag Racing Player's Choice Edition
One of the nicest drag racing simulations available, HOT ROD Championship Drag Racing includes a very good engine simulator. Two versions of the software exist, the Original and the Player's Choice Edition. Both have simulators that are quite similair to the Desktop Dyno software package in regards to input and output. Although the resultant graph of peak horsepower and torque is very small (in size), the output seems to be very accurate. Unlike Desktop Dyno, the simulator portion of the game doesn't provide printouts of the calculated data (however, screen capture is possible--see above). Nonetheless, the true benefit of having this software is the ability to test the engine built in a accurate drag racing environment. Each vehicle in the program is just as configurable as the engine, with separate sections for suspension, transmission, aerodynamics and tires. Unfortunately, there aren't any Dodge Trucks available as car choices, but there are six Mopars (including the AMC AMX). Don't fret, though, because there is a C#%vy pickup that could represent a Dodge Truck quite well both aerodynamically and mechanically.

Summit Racing's Engine Analyzer
Images from Summit Racing Equipment Catalog
The Summit Racing Engine Analyzer is available in three versions covering all levels of engine analysis and simulation. All three versions allow the user to print out torque and horsepower graphs along with the dyno results. The EZ version is the simplest version, with 20 inputs and 27 outputs. The Standard Version 3.0 offers 65 inputs and 50 outputs. Finally, the Pro Version allows for over 100 inputs and outputs along with a variety of graphing features. Also, data from any of the Summit Racing Engine Analyzers can be entered into their Drag Racing Analyzer for real-world style race simulation. These software packages are probably the most expensive of those listed here, and it is unknown how accurate they are. These software items are listed in the Summit Racing Catalog within the Tools section. More information:
