What is Static Boost?

Static Boost refers specifically to the pressure reading from the boost gauge when the engine is at rest, which means that the engine is not running. In this situation, the boost gauge displays the atmospheric pressure in the induction manifold without any influence from engine operation, such as intake enhancements from forced induction systems or any dynamic engine conditions.

This reading provides a baseline or reference for measuring how much pressure the intake system generates during active engine operation. The other options do not accurately describe Static Boost: the first option reflects atmospheric pressure rather than a gauge reading specific to engine conditions, the second option involves throttle position affecting operational readings while the engine is running, and the fourth option compares pressures that are relevant during engine operation rather than at rest. Thus, identifying Static Boost as the non-operational gauge reading is essential for understanding engine pressures in a broader context.
