Part of 1980-1986 Ford Bronco Data & Spec Plates
This document is page 2 of an engine dynamometer (dyno) test data sheet, uploaded to the gallery of a 1982 Ford Bronco. It is a tabular printout of a dyno pull recorded at roughly 0.1-second intervals from 7.105 seconds to 10.107 seconds into the run. Six columns are recorded: elapsed time in seconds, engine speed (RPM), horsepower (Hp), torque (ft-lb), acceleration in G's, and engine/exhaust temperature (E-Temp, degrees F). Over this segment, engine speed climbs from 5073 RPM to 5978 RPM. Horsepower dips slightly around 531.5 hp near 5246-5275 RPM, then climbs steadily to 570.7 hp at 5978 RPM at the end of the printed data. Torque falls from a high of 550.9 ft-lb at 5073 RPM to about 501 ft-lb near 5900-5978 RPM. Acceleration values range from 10.89 to 11.29 G's, and the recorded temperature rises gradually from 159 to 161 degrees F during the pull. The sheet contains no vehicle identification, engine description, test date, shop name, or part numbers, it is purely numeric run data, apparently continuing from Page 1 in the same album.
