Dynojet Dyno Sheet - 397.55 HP / 372.33 ft-lbs - 2003 Crown Victoria Kenne Bell

This is a Dynojet Research chassis dynamometer results sheet from a single run (RunFile_029.drf) using standard (STD) correction factor and a smoothing level of 5. The main chart plots Power (hp, left axis, 0–500) and Torque (ft-lbs, right axis, 0–500) against vehicle speed in mph (50–130). The run recorded a maximum power of 397.55 hp and a maximum torque of 372.33 ft-lbs, both measured at the wheels. The power curve (bold red) climbs from roughly 240 hp near 62 mph, rises steadily to the mid-300s by 80 mph, plateaus, and then climbs again above 110 mph to peak near 400 hp at approximately 122 mph before dropping sharply at the end of the run. The torque curve (lighter red) peaks in the low 370s ft-lbs around 78–80 mph and tapers gradually to the mid-340s at high speed. A secondary lower chart shows the Air/Fuel ratio trace (scale 10–18), which stays rich, hovering roughly between 10.5 and 12 throughout the pull, dipping lowest (~10.5) around 100 mph. The document was uploaded as a dyno attempt for a 2003 Ford Crown Victoria with a Kenne Bell supercharger; the sheet itself contains no vehicle identification.
