Which risk increases when turbocharger bearing oil supply lags during rapid acceleration?

💡 Explanation

When oil supply lags during acceleration, hydrodynamic lubrication fails as viscosity drops, leading to boundary lubrication because friction increases rapidly. Therefore bearing damage results, rather than surge, cracking or intercooler failure which require different thermal or fluid dynamic effects.
