What are the signs of turbo failure?

As a cryptocurrency and finance professional, I often encounter various technical challenges, but today, I'm particularly interested in understanding the mechanics of turbo systems. Could you elaborate on the telltale signs of turbo failure? I'm particularly interested in hearing about any unique symptoms or indicators that might arise in relation to turbocharged engines or, in a broader sense, any high-performance components within a financial system. Are there any common red flags to watch out for? And how can one detect these issues before they escalate into significant problems? Your insights into this matter would be greatly appreciated.
