If you are wondering how to install BOV on non turbo car, then you’re on the correct page. Adding a blow-off valve [BOV] to your car can help it run more efficiently and will also help to increase the engine’s life. In this article, we’ll be discussing its installation process in detail.

What Is A [BOV] Blow Off Valve?
The Blow-off valves are an important component of a forced induction system because they relieve pressure spikes between the throttle body and the turbo. A blowoff valve is also called a dump valve or compressor bypass valve. It is a pressure release system that is present in most turbocharged engines. Blowoff valves are used to reduce pressure in the intake system as the throttle is closed, thus preventing compressor surge. The underlying objective of a blowoff valve (BOV) is to protect the turbo against damage while ensuring smooth and reliable drivability.
A blow-off valve is connected to the intake tract. Inside the valve’s main housing is a vacuum chamber with a spring, a diaphragm, and a valve. The diaphragm reacts to pressure changes. At a predetermined vacuum, it’s pulled toward the vacuum source, compressing the spring inside the housing. The spring is connected to a valve that pulls away from its seat and releases the unwanted boost pressure.
The pressure side of the valve is usually connected to the pipe between the turbo and the throttle, and a vacuum hose on the top of the valve is connected to the inlet manifold following the throttle body. The valve is held shut by a spring. Some higher-quality blow-off valves allow you to select how much air is vented to the atmosphere and how much is reinjected into the turbo.
Blow-off valves are of 2 types; recirculated or vented. The bypass valve recirculates the boost pressure back into the intake. While the vented Blow-off valve discharges the boost pressure into the atmosphere instead of back into the intake.
How Does BOV Work?
Blow-off valves are used to avoid compressor surges, which can occur when the throttle on a turbocharged engine is suddenly closed. When accelerating, your engine’s exhaust gasses, or more particularly, your turbocharger’s exhaust turbine, drive the turbocharger. The exhaust gasses are compressed by the compressor wheel on the other side. When you let go of the throttle, the throttle valve closes. Still, the turbocharger continues running and continues to produce compressed air. However, because the throttle is closed, this air has nowhere to go, and pressure develops.
When the system is pressured, air returns to the turbo when the blow-off valve kicks in. It expels the compressed air into the atmosphere, saving the turbo from being damaged. This operation generates a range of noises that car lovers like. Surprisingly, some valves are designed to improve the sound. Some, for example, have trumpet-shaped outputs to improve the sound. It expels turbocharged air that has come down the incorrect side of the intake manifold into the environment. Longer turbocharger life, faster spool, and improved transient responsiveness are all benefits of installing a blow-off valve.
Most aftermarket blow-off valves are tightly sprung and/or adjustable, so they do not leak when idle. If the valve is overly stiff, this can result in a compressor surge.
However, when it comes to performance, the BOV falls short. It’s only for show. Moreover, depending on the valve, tightening it so that it does not leak air at idle may trigger a “compressor surge,” which is a fluttering noise produced when the turbo blade stalls out against high-pressure intake air.
Does BOV improve performance?
The BOV is a pressure release valve. Its purpose is to release the pressure inside the intercooler and charge piping whenever the throttle is closed. BOVs can have a slightly negative effect on applications such as drifting. When you’re on and off the throttle all the time, releasing all the charged air can hurt the throttle response and give some lag.
How To Install BOV On Non Turbo Car?
You can install BOV on non-turbos or automatic just for the beauty of it but it won’t work the way it works on turbos. So, if you want that wonderful sound that turbocharged vehicles make when shifting gears, you’ll need a turbocharged vehicle. Though installing the BOV is easy and it helps to improve your car’s performance. There is a need of removing the battery to install it. These devices are designed to add performance, and you can even use them on automatics.
A blow-off valve is a critical part of turbocharged vehicles. You’ll experience a compressor surge that will compromise their performance and reliability. A reliable BOV will also add a pleasing sound. Even it will increase the speed of the turboshaft, and it will remove the extra pressure on the clamps and wheels from the turbo compressor wheel. This can greatly improve the car’s performance and reduce engine wear. Having a BOV in place will remove unwanted gasses.
The first step of installing a BOV is to ensure that the valve is fitted properly or not. Several factors must be considered before installing a BOV on a non-turbo car. Choosing the right BOV is a crucial part of boosting your car’s performance. A high-quality blow-off valve will run more efficiently. You’ll get more bang for your buck if you buy the high-quality BOV.
Most aftermarket blow-off valves are adjustable and have a tight spring. Tightening the valve will increase the speed of the engine and will reduce the risk of the compressor surge. The engine will run at maximum efficiency if the BOV is installed properly. The cost of the BOV installation process is fairly simple. There are a few steps involved: If you are wondering how to install BOV on non turbo car?
Step 1:-
There should be enough space for installing the BOV.
Step 2:-
There is a need to find the correct location for installing BOV.
Step 3:-
Aside from the exhaust system, you should also check for the other parts as well. If your car consists of an exhaust valve, it is important to ensure that the outlet is vented properly.
Step 4:-
If you want to install a blow-off valve, you’ll need a vent pipe.
Hence, if you don’t know how to install BOV on non turbo car you can follow this method. Just keep in mind before installing BOV on a non-turbo car. No matter how much you like the sound. Blow-off valves are impossible to install in the normally aspirated car, they are for forced induction engines only. However, you should be aware that installing BOV on a non-turbo car will not increase its power output.
