Computer modeling is the engineering turbocharger that has enabled the tremendous advances in automotive technology we take for granted today. This is a screenshot from one of Beth Ann Dalrymple’s intake manifold “analyticals” or simulations. It models the air velocity and direction in a single thin slice through the intake’s plenum. The simulation takes several seconds to run through 720 degrees of crankshaft rotation to bring every cylinder into play, resulting in a surging wash of multi-colored arrows. This simulation easily identifies dead areas of slow air movement, or confused eddies of seemingly directionless air that can be energized by reshaping the plenum. View Related Article
