Neat software program that estimates hp and tq using a very wide variety of engine components for all makes of engines.
" Technical Overview: Here's how the DynoSim works: The simulation calculates the gas dynamic, thermodynamic, and frictional physics of virtually any 4-cycle internal-combustion engine. Horsepower is determined from an analysis and integration of cylinder pressures from 2000 to 11,000rpm. All basic engine components and specifications are accurately modeled, including bore, stroke, 1-to-12 cylinders, a wide range of cylinderheads and port configurations, valve sizes, compression ratios, naturally-aspirated and forced-induction systems, airflow, exhaust systems, and virtually any camshaft timing or valve lift. American and Metric units are supported, and conversion between unit systems is fast and easy. ProTools™ allows viewing, graphing, and printing "technical" engine data, including engine pressures (imep, bmep, fmep, pmep), power loss from friction, volumetric efficiency, and manifold vacuum at each power point within the dyno test. Use this data to gain deeper insight into engine operation and efficiency.
