Improve Your Engine Sound With the Best Blow Off Valves In Australia

Blow off valves are essential for any turbocharged car, helping to improve performance and enhance your car’s engine sound. If you want to upgrade your vehicle's sound and performance, installing a high-quality blow off valve is a great place to start. 

In this helpful blog, we’ll take a closer look at what blow off valves are, their importance for turbocharged cars, and why Car Mods Australia stocks the best blow off valves in Australia. 

What does a blow off valve do?

A blow off valve releases the excess pressure the turbocharger creates when the throttle is released. When the throttle is closed, the compressed air tries to force its way back through the turbocharger's compressor wheel, causing it to slow down or even stall. This can damage the turbocharger — that's where the blow off valve comes in. It releases the pressure, allowing the compressor wheel to spin freely. It diverts the excess pressure into the atmosphere or the intake system. 

Types of blow off valves

There are two main types of blow off valves — atmospheric and recirculating. Atmospheric blow off valves release excess pressure into the atmosphere, creating a distinctive hissing sound that car enthusiasts know and love. Meanwhile, recirculating blow off valves release the excess pressure back into the intake system, improving efficiency and reducing emissions.

At Car Mods Australia, our blow off valves include vented and hybrid models fashioned from highly durable billet aluminium. With a solid build, sleek design, space efficiency and easy installation, what’s not to love?

• Increased performance — Blow off valves will help maintain the health and performance of your turbocharger, which can lead to increased horsepower and torque.
• Better reliability — By reducing stress on the turbocharger, blow off valves will help prevent pressure spikes and surges, causing damage to the turbocharger over time.

Can you put a blow off valve on any car?

Blow off valves are most common for turbocharged cars to release excess pressure from the turbocharger when the throttle is closed, preventing damage to the turbo and other components. However, installing a blow off valve in a non-turbocharged car will not provide any benefits and can even cause issues if not done properly. We strongly suggest consulting a mechanic to seek further advice.
