What does BOV stand for?
And what does it do?

 

What's the context? My guess is Blow Off Valve, another name fore Wastegate? But outside of a turbo related thing I don't know...

 

Blow Off Valve is different from the wastegate...

 

Yes, a blow off valve protects when you shift.
Think of a straw. when you blow air through the straw it flows easily, when you close the end of the straw and keep blowing, there is alot of pressure then in the straw. a BOV opens when you close the throttle plate and releases all the pressure

A wastegate protects the turbo from overboosting. its connected to the manifold and has a spring in it, when ehough boost pressure is reached, the spring begins to give and the wastegate opens. this prevents the turbo from overboosting.

 

thanks

 

Wastegates do not "protect" from overboosting....they "regulate" how much boost a turbo creates....

 

but without a WG you would overboost and destroy the turbo
but yes, they do regulate the amount of boost.

 

OMFG!!! Kamin do you know what you did? This is the first time I didnt see you flame a noob for asking a noobish question. You still the funniest HT member here with the funniest replies I have read so far.

 

that straw concept is pretty funny.. I just made my own bov sound PPPSSSSSSHHHHTTTTTT

 

it was a legitimate question
now it the question was
"whats a BOV and how can i work one into my twin turbo setup on my civic?"
THEN he gets flamed.
But everyone has to learn at sometime. I remember when i was a newbie.
