Before getting into blow valves, it’s important to understand turbo flutter, also known as compressor surge. When you’re flat out and your turbocharged engine is producing peak boost, you have fast airflow at high pressure traveling through your intake system after the turbo compressor. When you let off the gas, you close the throttle body, momentarily giving you a spike in intake pressure but with no airflow. The air has to travel somewhere, so it heads back through the turbocharger. The fluttering you hear is the air escaping back through the turbo as the compressor wheel fights this motion. Though it sounds awesome, there is no performance nor reliability benefit from this occurring. That’s where blow valves come in.
