Computer simulations will never completely replace real world testing, but they can save you iterations and money spent on parts if you even catch one little thing that can improve your engine.

Also, people get too caught up in a exact number. So and So magazine article says this combo of parts is xxx horsepower, but I calculated xxx +/-15. I have witnessed dyno runs on the same exact engine with slightly different results (either different day, weather or shop). The dyno's have correction factors, but its not a exact science.

The most important use for simulation is finding trends and relative changes (camshaft, intake) and ultimately finding the best combination for the intended application of the engine (racing, street, torque, horsepower).
