Engine turbocharger blow off valves are a crucial component in high-performance vehicles, as they prevent damage to the turbocharger and engine by releasing excess pressure during acceleration. These valves work by diverting the compressed air from the turbocharger back into the atmosphere or intake system, resulting in a distinct "whoosh" sound. Blow off valves are available in a variety of designs and materials, including aluminum, brass, and stainless steel, and can be installed in both stock and aftermarket turbocharged vehicles. Properly functioning blow off valves can improve engine performance and longevity, making them a popular choice among car enthusiasts.

Frequently Asked Questions (FAQs)
1. Are blow off valves good for turbos?
Yes, blow off valves (BOVs) are beneficial for turbochargers. They serve the purpose of protecting the turbo from damage while ensuring smooth and reliable drivability. If you own a turbocharged vehicle or plan to turbocharge your car, investing in a good blow off valve is recommended.
2. Can a BOV damage my turbo?
No, blow off valves (BOVs) do not damage turbos. In fact, they are designed to improve the performance and longevity of the turbocharger system. BOVs help prevent damage by releasing excess pressure when the throttle is closed, ensuring a smooth transition and protecting the turbo from potential harm.
3. How do I get my turbo to flutter?
To create a flutter sound from your turbocharger, you can remove the blow off valve (BOV) and seal the opening where it was. This will create backpressure, causing the turbo to flutter. However, it's important to note that fluttering is not recommended as it can lead to potential damage to the turbocharger.
4. What happens if a turbo gets too much air?
If a turbocharger receives too much air, it can result in excessive pressure in the engine under maximum load. To prevent damage, a valve called a wastegate opens up, diverting some of the exhaust gases away from the turbine. This helps regulate the airflow and maintain the optimal operating conditions for the turbocharger.
5. How bad is a blown turbo?
A blown turbo can cause significant damage to a car's engine. While the car may still move with a blown turbo, it is highly recommended to stop driving it and have the turbo repaired or replaced as soon as possible. Continuing to drive with a blown turbo can lead to further engine damage.
6. Can you run a turbo without a blow-off valve?
Running a turbo without a blow-off valve is not recommended. The blow-off valve (BOV) serves the important function of releasing pressure inside the intercooler and charge piping when the throttle is closed. Without a BOV, pressure can build up and potentially cause damage to the turbocharger, leading to stalling and poor performance.
7. Can you put a blow-off valve on a diesel turbo?
In most cases, it is not possible to install a blow-off valve (BOV) on a diesel turbo in the same way as on a petrol engine. The setup of a diesel engine typically does not include a throttle body, which is necessary for the functioning of a traditional BOV. Therefore, the installation of a BOV on a diesel turbo is not feasible.
