Unleashing the Roaring Chorus: Blow Off Valve Flutter Explained
When it comes to cars, there’s nothing quite like the sound of a blow off valve (BOV) fluttering. It’s a unique, almost musical sound that can be addictive to listen to. But what exactly is a BOV? And how does it work? Let’s take a closer look.
What is a Blow Off Valve?
A blow off valve is a device that is fitted to the turbocharger of a car engine. Its purpose is to release excess pressure from the turbocharger when it is not in use. This prevents the turbocharger from over-spinning and damaging itself.
BOVs are typically made of metal or plastic and are available in a variety of sizes and shapes. They are typically installed between the turbocharger and the intake manifold.
How Does a Blow Off Valve Work?
When the turbocharger is spinning, it creates a lot of pressure. This pressure is used to force air into the engine’s cylinders. When the throttle is closed, the pressure in the intake manifold decreases. This causes the BOV to open, releasing the excess pressure into the atmosphere.
The fluttering sound that is associated with BOVs is caused by the rapid opening and closing of the valve. The faster the turbocharger is spinning, the more frequently the BOV will open and close, and the louder the fluttering sound will be.
The Benefits of a Blow Off Valve
There are a number of benefits to installing a BOV on your car. These include:
- Protects the turbocharger: A BOV prevents the turbocharger from over-spinning and damaging itself.
- Improves performance: A BOV can help to improve performance by reducing turbo lag.
- Adds a unique sound: The fluttering sound of a BOV can add a unique and aggressive sound to your car.
Choosing a Blow Off Valve
If you’re thinking about installing a BOV on your car, there are a few things you need to consider. These include:
- The size of your turbocharger: The size of the BOV you need will depend on the size of your turbocharger.
- The type of BOV you want: There are two main types of BOVs: recirculating and atmospheric. Recirculating BOVs return the excess pressure to the intake manifold, while atmospheric BOVs release it into the atmosphere.
- The sound you want: Atmospheric BOVs typically make a louder fluttering sound than recirculating BOVs.
