This document is a Dynojet Research chassis dynamometer graph produced by Muscle Motors Performance, with correction factor STD and smoothing set to 5. It plots results from a dyno run labeled RunFile_005.drf. The upper graph shows Power (hp, left axis) and Torque (ft-lbs, right axis) against Engine Speed from about 2,000 to 6,500 RPM, recording a maximum power of 361.60 hp and maximum torque of 365.26 ft-lbs. Torque peaks around the 5,000–5,500 RPM range at just over 350 ft-lbs on the graph, while horsepower climbs steadily and peaks near 5,700–6,000 RPM at around 360 hp. The lower graph plots Air/Fuel ratio (left axis, roughly flat around 12:1 through the run) and boost pressure (right axis), with a recorded maximum boost of 8.35 psi that rises progressively with RPM, peaking near 6,000 RPM before falling off. A handwritten notation at the bottom appears to read "81 8-341-RACE" or similar. The upload attributes this to a 2004 Ford Crown Victoria ("Casper Dyno 2012"), and the boost trace indicates a forced-induction (supercharged or turbocharged) setup. The document itself contains no vehicle year, make, or model information.
