This document is a chassis dynamometer (dyno) results sheet produced on Dynojet Research equipment at DaSilva Racing, 960 Brock Road, phone (905) 837-7700. It presents three stacked graphs plotted against vehicle speed (40–140 mph): rear-wheel power (hp, 0–400 scale), torque (ft-lbs, 0–500 scale), and air/fuel ratio (10–18 scale). The run file is RunFile_021.drf, recorded 6/2/2011 at 1:13:05 PM, run type RO. Recorded peak values are Max Power = 356.66 hp and Max Torque = 379.86 ft-lbs. Run conditions were 72.14 °F, 29.88 in-Hg barometric pressure, 22% humidity, with a standard correction factor (CF: STD, STD: 1.00) and smoothing set to 4. The air/fuel trace shows a cursor annotation "X = 46.6" and the mixture running around 15–16:1 at lower speeds, richening to roughly 12–13:1 above about 90 mph. Power climbs steadily to a plateau near 356 hp around 120–130 mph before dropping at the end of the run. The sheet does not identify the vehicle, engine, or gear used; it was uploaded to a 1985 Mercury Grand Marquis gallery but contains no vehicle-specific identification.
