Sometimes theory is neat, but sometimes it fails to describe what actually takes place. The theory of internal combustion engines falls into this category, especially with respect to the function of ...

A.Pressure "excursions" (variations in intake manifold mixture flow pressures) are shown here in a trace of pressure vs. time (or crankshaft angle) in only one runner of a single-plane manifold. Since ...

Last month we showed what gains were available from three aftermarket Three-Valve intake manifolds in naturally aspirated trim. This month we're going to try the same three intakes, only now we'll see ...

Intake manifolds may not be the most well-known automotive components, but that doesn't take away from their importance. These devices are responsible for sending a precise mixture of fuel and air to ...
