3.3.2.2 Air Flow Path
The air flow path in the vehicle at the air inlet of the air induction system shall not be
obstructed with vehicle components that will cause loss of pressure or flow disturbance.
obstructed with vehicle components that will cause loss of pressure or flow disturbance.
All performance parameters specified in paragraph: 2.3.2.1 were measured with a maximum
air restriction of 1” of Hg.
air restriction of 1” of Hg.
As reference in table 3.3.2.1 - I, development power and torque data is shown to illustrate
the order of magnitude that may result as increasing the induction restriction.
