| Intake manifold runner flow testing |

| These pictures help explain flow path behavior in differing shaped runners. This is an important consideration when modifying manifold runners and even more so for the BBF's symetrical intake port layout. Note that the short turn and long turn radii are not necessarily on the horizontal. It depends on the flow path shape. |
