This document is a Dynojet Research chassis dynamometer comparison chart (correction factor STD, smoothing 5) plotting two dyno runs against engine speed from roughly 2,000 to 6,500 RPM. The legend identifies RunFile_018.drf with a maximum power of 277.07 hp and maximum torque of 300.53 ft-lbs (red curves), compared against RunFile_001.drf with a maximum power of 230.98 hp and maximum torque of 244.77 ft-lbs (blue curves). The main plot shows Power (hp) on the left axis and Torque (ft-lbs) on the right axis, both scaled from 50 to 325. The higher run peaks near 300 ft-lbs of torque around 3,800–4,200 RPM and holds roughly 275 hp from about 5,200 RPM through 6,000+ RPM, while the baseline run peaks around 245 ft-lbs and roughly 231 hp near 5,300–5,600 RPM. A lower panel plots Air/Fuel ratio (10–18 scale) for both runs, showing both mixtures generally between about 12.5 and 14.5 across the RPM range. The chart documents a gain of approximately 46 hp and 56 ft-lbs between the two setups. The upload title indicates the same camshafts were used with a different setup on the owner's car, nicknamed "EvilVic."
