How to Use Engine Analyzer Pro V3.9 to Simulate and Optimize Your Engine Performance
If you are a professional engine builder or engineer who wants to simulate, predict and analyze stock or race engine dynamometer (dyno) performance, you need a powerful and reliable software tool that can handle various combinations of cams, heads, intakes, superchargers, etc. and show you the effect on torque, HP, air flow, fuel flow, maximum cylinder pressure, volumetric efficiency, etc.
One such tool is Engine Analyzer Pro V3.9[^1^], a comprehensive software package from Performance Trends Inc. that lets you try different engine designs and modifications on your computer and see how they affect your engine performance. You can also investigate the effect of spark advance, valve flow, ring leakage, cam profile, rod length, turbocharger boost level, intake manifold temperature, exhaust backpressure level, and many more factors on your engine output.
Engine Analyzer Pro V3.9 is not only a simulation tool, but also an optimization tool that can help you find the best engine design for your application. You can let the software sort through numerous engine combinations and find the one that gives maximum performance. You can also interface with other Performance Trends software programs such as Drag Racing Analyzer[^2^], Circle Track Analyzer[^3^], or Fuel Economy Calculator[^4^] and see how your engine performance affects your vehicle performance.
In this article, we will show you how to use Engine Analyzer Pro V3.9 to simulate and optimize your engine performance in a few easy steps.
Step 1: Install and Run Engine Analyzer Pro V3.9
To use Engine Analyzer Pro V3.9, you need a Windows PC with Windows XP, Vista, 7, 8, 10 or 11 operating system. You can download the software from Performance Trends website[^1^] or buy it from AliExpress[^5^] or other online platforms. The software costs $469 for the standard version or $669 for the Enterprise Edition that has some additional advanced features.
After downloading or receiving the software package, install it on your PC by following the instructions on the screen. Then run the software by clicking on the icon on your desktop or start menu. You will see the main screen of Engine Analyzer Pro V3.9 as shown below:
This is where you can enter or modify the engine specifications and options for your simulation. You can also access various menus and buttons to perform different tasks such as saving or loading files, running calculations, viewing results, printing reports, etc.
Step 2: Enter or Load Engine Specifications
The first thing you need to do is to enter or load the engine specifications for your simulation. You can either enter them manually by typing in the values in the boxes on the main screen or load them from a file that contains predefined specifications for various engines.
To enter them manually, you need to know some basic information about your engine such as bore, stroke, rod length, compression ratio, number of cylinders, valve sizes, cam timing, etc. You can also enter more detailed information such as piston design, head design, intake system design, exhaust system design, supercharger type and size, etc. if you want to simulate more accurately.
To load them from a file, you can click on the File menu and select Open Engine File. You will see a dialog box that allows you to browse and select a file that contains engine specifications. The software comes with several sample files for different types of engines such as stock engines, race engines, turbocharged engines, etc. You can also create your own files by saving your engine specifications using the Save Engine File option in the File menu.
After entering or loading your engine specifications, you can click on the Calculate button on the main screen to run the simulation and see the results.
Step 3: View and Analyze Results
After running the simulation, you will see a new window that shows you the results of your a474f39169
