What does more plenum volume do?
Increasing plenum volume beyond 4.8L resulted in significant improvement in performance parameters. Overall, peak power was shown to increase from 54 kW to 63 kW over the range of plenums tested.
How is intake manifold volume measured?
By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time.
What is the purpose of a plenum in car?
The plenum chamber is a chamber located in front of the windshield, where air pressure is above atmospheric. It provides a volume of air which is drawn into the car from the chamber through the heater, air-conditioner or vents.
