Many times I saw on the streets cars with this.. I guess it may be some air intake or something..,. When they change the stick there is a compresion air sound comming from the car. Like in fast and furious What is it exactly??
I'm not sure exactly what your talking about but it could be from their intake or maybe their intercooler for their turbo
are you referring to the blow off valve?
He doesn't know what he's refering to. That's why he asked. :wink2:
It's a blow off valve that vents excess pressure that can cause damage to
the (turbines?), as the throttle plate closes, and there's too much
pressure built up.
It's mainly used for the sound effect, though.
Everything in the fast and the furious series is wrong, by the way.
... yeah, like the hole purging thing from the skyline in the start of the 2nd one!!!!
So the conclusion is that this is just sound effect and it is not so good for the engine. Yes?
The blowoff does have a purpose, but most people use it for effect rather than to protect engine/turbo parts
