Blow Off Valve vs No Blow Off Valve | Sound and Science 

Today I ran my turbocharged car back to back, with and without a blow off valve (BOV). This included a sound comparison, an explanation of what a blow off valve is and what it does, and finally, my thoughts on if you need a blow off valve on a turbo car.
The car in this video is 2Broke2Boosted, my budget turbo Mazda Miata. This car is running an eBay, HKS knock off blow off valve that's been installed for the life of the turbo setup (since 2020). You can see more of this car on my channel!
