Ford 351W Comp Cams 31-255-5 Dyno2000 Power, Torque & Engine Pressure Table

This document is page 3 of 5 from a Dyno2000 Version 3.08 engine simulation printout for a file named "351W Comp 31-255-5.dyn", a Ford 351 Windsor engine simulated with a Comp Cams 31-255-5 camshaft. The table, titled "Calculated Power and Engine Pressures," lists simulated results at 500 RPM increments from 2000 to 11000 RPM. Columns include flywheel horsepower, flywheel torque, intake manifold pressure, volumetric efficiency percentage, and IMEP, FMEP, and BMEP pressures. Peak torque is 322 lb-ft at 4500 RPM, while peak power is 297 HP at 5500 RPM. Volumetric efficiency peaks at 94.7% at 5000 RPM. Power and torque fall rapidly above 6000 RPM, reaching zero at 9500 RPM and above, where BMEP goes negative (down to -55.3 at 11000 RPM) as friction (FMEP) climbs steadily from 17.4 at 2000 RPM to 59.5 at 11000 RPM. A reader can use this to evaluate the powerband of a stock-type 351W with this flat-tappet Comp cam, comparing it against other cam and head combinations in the same album of dyno simulations.
