Ford 351W with Mustang HO Cam - Dyno2000 Power, Torque & BMEP Table
Dyno2000 v3.08 data table (351W HO cam.dyn) of calculated power, torque, intake-manifold pressure, VE and mean effective pressures by RPM; peaks 311 HP @ 5000 and 343 lb-ft @ 4500.
This document is page 3 of 5 from a Dyno2000 Version 3.08 engine simulation printout, filed as "351W HO cam.dyn." It presents a table titled "Calculated Power and Engine Pressures" for a Ford 351W (Windsor) engine simulated with a Mustang HO camshaft. Data columns cover engine RPM (2000 to 11000 in 500 RPM increments), flywheel power (hp) and torque (lb-ft), intake manifold pressure, volumetric efficiency percent, and IMEP, FMEP, and BMEP pressures. The simulation shows peak torque of 343 lb-ft at 4500 RPM and peak power of 311 hp at 5000 RPM, with volumetric efficiency peaking at 86.4% at 5000 RPM. Power falls off rapidly above 7500 RPM, reaching zero by 9500 RPM as friction losses (FMEP rising from 17.4 to 59.5) overcome cylinder pressure, and BMEP becomes negative above 9000 RPM. A reader can use this table to evaluate the powerband of a stock 351W roller engine fitted with a 5.0 HO cam, useful for cam selection comparisons; it belongs to an album of similar dyno simulation printouts comparing various cams and cylinder heads on 351W/357W builds.
