How a Blow-Off-Valve Works

One of the easiest ways to improve travel photos is shooting in better light, and the best light is often in the hour after sunrise and before sunset. That’s because the light takes on a warm golden hue and hits the subject from the side instead of the top. t’s difficult to recreate the grandeur of a vast landscape in the confines of a picture frame.

We’ve all heard the distinctive sound of a Blow-Off-Valve, but what exactly does it do, how does it work, and how do you know which type to buy for your car?

In this video we explore the basic principles of the induction system on a turbocharged or supercharged vehicle, how a Blow-Off-Valve works, and the pros and cons of fitting on to your car.

The different types of valve including Bypass, Dual Port and Atmospheric are also discussed.
