This document is a Dynojet Research chassis dynamometer results sheet titled 'RWTD' from a dyno shop located at 3016 Dauphin St., Mobile, AL 36606, phone (251) 479-9451. It records three dyno pulls made on 3/1/2006 (RunFile_003, _005, and _006), all Run Type RO, with SAE correction factor (SAE: 0.98) and smoothing set to 5. The graph plots rear-wheel power (hp) and torque (ft-lbs) against engine speed from roughly 1,500 to 6,000 RPM, plus an air/fuel ratio trace along the bottom. Peak results: Run 003 made 268.43 hp / 307.73 ft-lbs; Run 005 made 271.73 hp / 313.34 ft-lbs (best run); Run 006 made 271.62 hp / 312.67 ft-lbs. Ambient conditions for each run are listed (82.19–85.58 °F, ~30.25 in-Hg barometric pressure, 22–26% humidity). A cursor at 3,329 RPM shows torque values of 295.76, 295.67, and 288.89 ft-lbs, power of 187.38, 187.33, and 183.02 hp, and air/fuel ratios of 13.23, 13.03, and 12.74 across the three runs. The A/F trace holds near 13:1 through the pull. Uploaded to a 2003 Ford Mustang gallery; the sheet itself doesn't identify the vehicle.
