Hey emsvitil,
I'm not sure what you’re thinking or what the point of your question was?
You probably already know….
Many dyno torque/HP curve charts have dips and peaks, whether tested on a chassis dyno, engine dyno, or a software dyno program.
Where in the RPM range a dip occurs can vary depending on a number of factors.
Engine Analyzer simulates so by definition it could be considered not real world… it’s theoretical, but highly repeatable.
An engine tested on a SuperFlo 902 is real world, with some simulated data included… highly controlled environment and only slightly theoretical (mathematical formulas are applied)
An engine tested in vehicle on a chassis dyno is real world, with some simulated data included, with added physical components…. perhaps considered more real world, still somewhat theoretical (mathematical formulas are applied)
A 4th paradigm is when the vehicle is tested on a road course, track, or actual conditions (i.e. drag strip) by the driver. Actual results of target changes, tuning or component changes, may or may not parallel what was predicted in the Engine Analyzer software, shown on the charts and data from the SuperFlo dyno, or the DynoJet chassis dyno test results.
The driver’s butt-dyno provides “real world feedback” and track times can prove or disprove all previously theoretical, predicted, or data test results.
Gnarls.
