An intake air booster for boosting air flow in an internal combustion engine or the like which includes a first air passageway communicating directly with an engine intake manifold having a plurality of interleaved rotating and stationary blades, the rotating blades forming a second internal passageway, the stationary blade providing an outer housing, so that air passing through this first passageway will be stirred by virtue of the interaction against these blades; the second air passageway formed by an internal band contained on the rotating blades includes caps on bottom and top portions of the passageway provided with a plurality of inlets and outlets and a source of compressed air adapted to engage the cap and by so doing providing additional air through the air passageway while simultaneously increasing the rotation of the rotary blades in the first air passageway, the source of compressed air including a reservoir and appropriate valving and sensing means which selectively engage the compressed air for the additional throughflow. In this manner, beneficial air can be combined with an increased fuel delivery for more efficient combustion and power.
