Manifold pressure during the second stage of turbocharging remains regulated by the primary turbocharger's wastegate there is only one turbine by-pass valve in the whole system.

In aircraft engines, turbocharging is commonly used to maintain manifold pressure as altitude increases ( i . e . to compensate for lower-density air at higher altitudes ).
33.
Throttle valves in the updraft carburettor throat were controlled by an automatic boost control through the throttle linkage to maintain the selected manifold pressure with changes in altitude.
34.
Due to the loss of oxygen and to escape their attackers, Zeamer dived the plane violently from to approximately, estimating the altitude by an increase in engine manifold pressure.
35.
As the carburetor air temperature ( CAT ) indicator does not read correctly below of intake manifold air pressure, icing conditions require applying full carburetor heat below of manifold pressure.
36.
The day we qualified we were running late because of the weather and for some reason we didn't get the boost ( manifold pressure from the turbocharger ) we wanted.
37.
CART maintains it notified engine manufacturers earlier this week that all cars would be fitted with an extended manifold pressure relief valve _ starting at this weekend's Detroit Grand Prix.
38.
This effectively alters the flow rate of air pressure through the valve, changing the rate at which air bleeds out of the T in the manifold pressure reference line to the wastegate.
39.
The "'Turbo A "'models also measured air based on manifold pressure rather than using an air flow meter, had a larger intercooler, larger throttle body, optimized CT-26 turbo, and various other differences.
40.
But two weeks after the race, USAC took away the Penske advantage, cutting the maximum mercury manifold pressure, or boost, for the Mercedes and any similar pushrod stock block-type engine from 55 to 52 inches.
