The Engine Analyzer Pro is a comprehensive software package for the professional engine builder or engineer to simulate an engine build-up or modification. It let's you try various combinations of cams, Heads, intakes, superchargers, etc. and see the effect on torque, HP, air flow, fuel flow, maximum cylinder pressure, volumetric efficiency, etc.
For example, its detailed calculations allows you to investigate the effect of:
"Its like having a dynamometer with detailed instrumentation right in your computer."
You can let the Pro sort through numerous engine designs on the computer to find the one giving maximum performance. You won't be wearing out your engine on the dyno, or wearing out your check book buying parts. Whatever your application, turbocharged, Nitrous Oxide injected, naturally aspirated or restricted, the Pro can save you time and money finding that extra power. In the process, you will gain insight into engine theory. You can "see" the combustion process, watch air flow past the valves or tuning pressure waves in the runners, power lost to friction or to the cooling system, etc.
When finished, enter the Pro's results into our Drag Racing Analyzer (std or Pro version), Circle Track Analyzer, or Fuel Economy Calculator and see the effect on ET, MPH, top speed, lap times, MPG, etc. Results can be sent automatically to these programs via our "Auto-Link" features.
Engine Simulations will never replace dyno testing, however they do have advantages:
When you find a new design with big gains, you will find or develop the required technology. Then use your dyno to verify and fine tune the "computer optimized" designs.
The Pro is a more detailed program than our more std Engine Analyzer. It requires more inputs and requires about 200 times more calculation time. If you think the Engine Analyzer is too technical, you do not want the Pro. The Pro's major advantages include:
Most any output can be graphed or exported as an ASCII file, including detailed cycle data as listed here:
