The volumetric efficiency table is probably the most important one in any ECU.The vertical axis is engine load, in this case, MAP, manifold absolute pressure, which is the pressure inside the intake ...

When Ford introduced the SEFI 5.0L High Output Mustang in 1986 many predicted the end of the tunable engine. Ironically it was the beginning of a new era of super-tunable small-block Fords that would ...

Among theories advanced to explain the phenomenon, there appear to be two prevailing concepts that deal with the "tuning" of intake and exhaust systems. One involves the study and application of how ...

This is a preview. Log in through your library . Abstract In order to improve the volumetric efficiency of a crankcase-supercharged 4-stroke cycle engine in the high speed range, rotary disc valves ...

SAE Transactions, Vol. 88, Section 2: 790267–790526 (1979), pp. 1756-1782 (27 pages) In order to obtain the limiting volumetric efficiency curve, the relationships between volumetric efficiency and ...

Regardless of the larger target of extracting big power from your engine build is the primary goal of building a well-tuned combination that provides strong performance across the rpm band. And as ...
