Before you plop your credit card on those headers, oil cooler, pulley, camshaft, turbocharger, cold air box, and fuel injectors you might want to check this new engine simulation software from ProRacing Sim - Dyno 5 Sim. According to
Hemmings eWeekly:
The basic program works like this: The user fills in fields in what looks like a typical tech sheet for an engine, with blanks for critical specs, including bore, stroke, compression, valve sizes, camshaft profile, and much more. Some fields provide a selection of typical choices for users who may not have specifics on their own combination, though the option to enter very specific figures is usually available. Once the data is entered, the “engine” can be effectively run through its theoretical power band using the DynoSim software, producing test results just as if the actual engine had been built and tested.
