What Does A Blow Off Valve Do On A Turbo? (Complete Answer)

Blow-off valves are an essential part of a forced induction system, as they vent off pressure surges between the engine and the air conditioning system. (BOV) is located on the intake side of the combustion chamber. This is called a closed-loop system and is the most efficient way to run an engine.

It is important to note, however, that this is not the same as a “blow-by-blow” description of how the system works. For example, if you were to blow a hole in a piece of paper, you would not be able to see how it was made.

In the case of an air conditioner, the only thing you can see is how much heat is being generated by the heat exchanger, which in turn is used to cool the compressor. However, when you blow off a valve, all you are doing is blowing off the pressure that is building up inside the unit.

Does a blow-off valve make turbo flutter?

BOV isn’t doing its job if a car is making a fluttering noise at highrpm and boost. Contrary to popular belief, the noise is not coming from the intake manifolds.

This is why you should always check your exhaust manifolds for leaks before you start your engine up. You’ll also want to make sure that your turbo is running at the correct boost level, as well as that you’ve got a good tune up on your ECU.
