Engine Dyno Simulator (Beta)

Model an engine's torque and power curve in your browser. Edit the short block, head, cam, exhaust and induction, add boost or nitrous, and read off torque, power, VE and a knock estimate. Build and tune your own engine. Logged-in members can also save, export and reload their parameter sets. The results are only as good as what you put in: you need a complete, realistic set of specs (bore, stroke, rod length, compression, valve sizes, cam timing and lift, and runner and exhaust dimensions). Changing one or two numbers on a vague or incomplete combination gives vague numbers back (garbage in, garbage out).
