Dyno2000 Simulation: 4.17 Stroke 10.79:1 Engine Power, Torque & BMEP Table

This document is page 3 of a computer engine simulation printout generated by Dyno2000 (Version 3.08) for a build labeled 'Derrick36 crane 4.17 stroke 10.79 compression'. Titled 'Calculated Power and Engine Pressures', it tabulates simulated engine output from 2000 to 11000 RPM in 500 RPM increments. For each RPM point it lists flywheel power, flywheel torque, intake manifold pressure, volumetric efficiency percentage, and three mean effective pressures: IMEP (indicated), FMEP (friction), and BMEP (brake). Peak torque is 545 (Fly) at 4000 RPM, and peak power is 501 (Fly) at 5500 RPM, where volumetric efficiency reaches its highs near 96% around 4500-5000 RPM. Above 5500 RPM, power and torque decline steadily, with power and torque calculated at zero from 10000 RPM upward and BMEP going negative (down to -33.7 at 11000 RPM) as friction losses exceed indicated output. The header indicates the engine build uses a Crane cam, a 4.17-inch stroke, and a 10.79:1 compression ratio. A reader can learn the predicted powerband, efficiency curve, and pressure characteristics of this stroker engine build across its full RPM range.
