A dump valve, also known as a blow-off valve (BOV), is a crucial component in turbocharged engines. Its primary function is to release excess boost pressure when the throttle is closed, preventing compressor surge and protecting the turbocharger. Here’s a detailed overview:

Functions

  • Pressure Release: When the driver closes the throttle (e.g., during gear changes), the dump valve opens to release excess pressure from the intake system, preventing back pressure on the turbo.
  • Compressor Surge Prevention: By venting excess boost, it helps avoid compressor surge, which can damage the turbocharger over time.
  • Improved Turbo Response: Keeping the turbo spinning by preventing pressure buildup allows for quicker spool times when the throttle is reopened.
