The Horsepower Calculator – Lifetime Access! – HorsepowerCalculators.net – Home of the Virtual Dyno & The comprehensive horsepower calculator

The horsepower calculator is applicable to all levels of buildup from the most basic bolt on packages to the more advanced engine builds. The calculator will help entry level enthusiasts find the best specifications for bolt on power parts such as cold air intakes, streetable long tube headers, and cat-back exhaust systems as well as ignition and tuning upgrades to maximize the performance and efficiency of a slightly modified street engine.

For more advanced all motor buildups, the calculator will help recommend a proper match of parts that all target peak power new redline including tuned length intake manifolds (or individual throttle body setups), shorty headers for peak power extraction, ported high flow cylinder heads, ideal lift and duration camshafts and a recommended static compression ratio that will match both the engine demand and the camshaft profile of the specific buildup.

For turbocharged applications, the calculator specifies everything needed to perform a complete and matched turbocharged conversion covering everything from choosing the right sized compressor, to selecting an optimal turbine aspect ratio (A/R) for best spool, to recommending a proper single or dual wastegate size for solid boost control, to coupling properly sized exhaust manifolds, and intercoolers in order to maximize the performance of the system.

Similarly, for supercharged applications the calculator specifies everything needed to perform a complete and matched supercharger setup including the proper supercharger head unit, a header designed for maximum exhaust gas evacuation and minimum back-pressure, a split patter camshaft selection to minimize exhaust gas reversion and supercharged air dilution, and the proper match of cold side and hot side piping for best torque response.

On Nitrous applications, our calculator does complete calculations for a higher demand fuel system to cope with the nitrous kit’s fuel demand. We also calculate exact single…
