Meaning of overboost | Babel Free

Definitions

To increase an engine's intake manifold pressure to higher levels than it is designed for.

Examples

“It makes sense⟳ to provide⟳ plausible engine fuel and ignition mapping to the limits of the factory fuel injectors, which would typically be sized sufficiently large to provide⟳ optimal fuel to the airflow/boost⟳ limits of the stock⟳ turpocharger even though the wastegate should normally prevent⟳ the engine from boosting so high. This is because the engine can overboost if the wastegate manifold-pressure reference line is cut⟳ (melted, crushed, disconnected, and so on), and a "safe" calibration -- even in forbidden overboost territory -- is one more countermeasure designed to help⟳ avoid⟳ engine damage⟳ from lean⟳ mixtures if the engine does overboost if fuel cut⟳ strategies fail⟳.”

“Morgan was waiting outside in the bay. Didn't even wait⟳ for me to say⟳ a word. "What happened? Why did you overboost? You could have⟳ blown the whole shuttle, the whole expedition."”

“Overboosting is not something that “just happens.” Usually, it's under the control⟳ of the pilot, or can at least be prevented by an alert pilot.”
