1997 Mercury Grand Marquis 4.6 Dyno Sheet - 199 HP / 238 TQ Dynojet Results

This document is a Dynojet WINPEP 7 chassis dynamometer test sheet (Dynojet Performance Evaluation Program) produced by Dynojet Research and run at C&M Performance, 3045 Beechwood Industrial Ct., phone 262 993 6605. The sheet records a single dyno run (RunFile_001.drf) performed on 5/18/2007 at 9:26:32 AM for a 1997 Mercury Grand Marquis with the 4.6 engine. The run type is RO with SAE 1.00 correction factor and smoothing of 5. Test conditions were 76.62 °F, 29.43 in-Hg barometric pressure, and 27% humidity. Results show a maximum power of 199.16 hp and a maximum torque of 238.51 ft-lbs (rear-wheel figures on a Dynojet). The main graph plots power (hp) and torque (ft-lbs) against engine speed from 2,000 to 6,500 RPM, with torque peaking near 3,800–4,000 RPM and power peaking around 4,800–5,000 RPM. A secondary lower graph plots the air/fuel ratio across the same RPM range, holding relatively flat with a dashed target/reference line. The footer reads 'Your Ford Performance Headquarters.' A reader can learn the car's measured dyno output, test conditions, and the shape of its power, torque, and air/fuel curves.
