It produces six to eight pounds of boost pressure.
Requested boost pressure is raised somewhat on automobiles with manual gearbox.
As engine speed increases, the vanes readjust to maintain boost pressure.
The boost pressure produced can be regulated by a system of release valves and electronic controllers.
As a result, the charge density is reduced and the cylinders receive less air than the system's boost pressure prescribes.
This gave a relatively low boost pressure and was more of a scavenge blower, but it could increase output power by up to 50%.
The ability to help the wastegate remain closed as boost pressure builds can be increased.
They are connected in a series so that boost pressure from one turbo is multiplied by another, hence the name "2-stage."
It is a one-to-one relationship with an offset of -100 kPa for boost pressure.
After the race, the rules were changed in order to reduce the amount of boost pressure supplied by the turbocharger.
