Factors to Consider When Buying the Best Sounding Blow Off Valve

In order to make the right decision, here are a few considerations that you need to keep in mind when buying the best sounding blow off valve.

Compatibility

All blow-off valves are not universally built. So, you can’t buy any BOV for your turbocharger. In this case, a little research is necessary to know what model is compatible with your car. You can also know more form us about painting issues.

Without checking the compatibility, you mustn’t make a buying decision.

Whoosh Noise Rating

Blow-off valves are popular for creating “whoosh noise.” These sounds are so aggressive that they sometimes turn head toward the vehicle when driving on the road.

However, the noise created by the BOVs varies depending on the brand and product. So, it would be best if you choose what sound level you want for your turbocharger.

Interestingly, different models are available that create low sound or remain silent when shifting.

We recommend you check the blow-off valve’s noise rating before buying. Also, learn your preference.

Valve Size

The installation slots of a BOV vary depending on the vehicle type.

Although you will find most BOV with 40 mm diameter, the size may differ from car to car.

So, check the installation slot and identify what size is ideal for your vehicle. Thus, you can avoid inconvenience later.

Installation

Ensure that your selected blow-off valve is easy to install or bolt into your car.

Installing a blow-off valve is not a challenging task and can easily be installed without taking assistance from a professional. Generally, every BOV comes with an installation manual to assist you. Thus, an easy-to-install BOV helps you save valuable money.

Durability

Since the blow-off valve is placed under the hood, it faces high heat, oil, grease, etc. As a result, damage and crack can easily appear if made of inferior material. Choosing the right oil is also a very important fact.

Buy a model made of durable materials such as stainless steel, solid Billet Aluminum, Die-cast Aluminum, etc. Impressive build quality guarantees corrosion-free and long-lasting durability.

This is a factor to consider if you don’t want to frequently buy a BOV for your turbocharger.

Ease of Maintain

To avoid daily wear and tear, maintaining and cleaning the valve is also essential.

So, choose an easy-to-maintain blow-off valve that doesn’t take much of your effort and time for maintenance purposes.

 

How to Install a Blow Off Valve?

Most BOVs are easy to install. If you install a greddy BOV for the first time in your turbocharger yourself, follow the below steps meticulously.

Step 01: Disconnect the Cable

Open the hood to disconnect the negative and positive cables from the battery terminal.

Step: 02: Battery removal

Then take out the battery.

Step 03: Identifying Factory BOV

Locate the factory blow-off valve by taking assistance from the shop manual. This valve is responsible for recirculating intake air to the exhaust. It needs to be replaced. You will find a connection between the 2 hoses and the vacuum lines. The throttle body is connected to the vacuum line. Your vehicle’s BOV operates due to the vacuum pressure.

Step 04: Hose Clamps and Screws Removal

Grab a socket wrench or screwdriver. Use it to remove the hose clamps and screws.

Step 05: Vacuum Lines Closing

The hose clamp needs to be slid out of the way. Now, close both vacuum lines using the screwdriver.

Step 06: BOV Installing

Next, install the BOV. Also, follow the opposite process while installing the hoses. Place the battery back in its position. First, connect the possible cable to the battery, then go with the negative cable.

You are all done with the installation process of a BOV in your turbocharger.

 

Frequently Asked Questions

Do superchargers require BOV?

Blow-off valves are specially designed for turbochargers. So, if you plan to buy a BOV for your supercharger, it will be a waste of money. A typical supercharger uses forced induction and recognizes pressure easily. That is why, to detect and release pressure, installing a BOV in a supercharger is entirely unnecessary.

Can a blow of a valve damage your engine?

An adequately installed blow-off valve will not damage your engine. The responsibility of a BOV is to prevent surge loading and withstand the speed of the turbine between shifts. This unit increases a turbocharged engine’s shelf life and acts as a safeguard.

Can you run a turbo without a blow-off valve?

If a blow-off valve is unavailable in your turbo, the intake air gets released from the back through the vehicle. It puts a lot of load on the turbo. A blow-off valve eliminates this load by removing air and helps your turbo engine perform efficiently for many days.

What can I clean my valve cover with?

You can clean valve cover using compressed air. Also, a brush or a rag will be a good option. Besides, some mechanic shop uses acid based cleaner to get oxidation and other stuff for cleaning the valve cover.

 

Wrapping Up & Top Pick

So, by now, you know the importance of the best sounding blow-off valve for your turbo. A perfectly fitted BOV will surely improve your turbo performance while providing aggressive sound during shifting.

We recommend buying the Q Series 50mm Blow Off Valve for your turbocharger. It is robustly built with durable materials, then coated with anodizing and lubricated using PTFE.
