overboost

動詞

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

日本語の意味

エンジンの吸気マニホールド内の圧力を、設計上許容される水準よりも高いレベルまで増大させること

Experienced racers sometimes overboost their engines for a temporary power surge, but doing so can severely shorten engine life.

経験豊富なレーサーは一時的なパワーを得るためにエンジンの吸気マニホールド圧を設計上の限界を超えて上げることがあるが、そうするとエンジンの寿命が著しく短くなることがある。

意味（1）

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

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.
