VIDEO - How a Blow Off valve works, what it does and how to choose the right one.
 

Hi all,

In the latest Project BRZ video I explain how a Blow Off Valve works, exactly what its function is on a boosted car, and how to choose the right one for your boosted car.

I hope some of you find this useful!

This was very informative, thank you

You're welcome mate. Glad you found it useful :)

Did you use the softer blue spring for this rotrex supercharger application? It's my understanding in a centrifugal supercharger application, the valve should be slightly open during idle and low load/low rpm conditions to stay out of boost and improve gas mileage.
