hey...wat i know is that BO sounds are made when the accelerator pedal is let go rite?not when u the gear is changed rite?
and wat is a boost leak?

YEs of coz. the purpose of your blow off is to release the turbo pressure from your turbo manifold when your throttle butterfly closes. Otherwise the air pressure will be too high for the given fuel mixture and cause detonations.

boost leak is a leak in your turbo manifold therefore you're not getting the full pressure of your turbo. could be leak in your blow off too.

Eh? How will the absence of a BOV cause detonation? Care to explain a bit? I've only heard of reverse pressurised airflow causing compressor surge and in extreme cases causing compressor wheel damage and turbo failure.

Boost leak usually refers to a leak in your intake between the turbo and intake port. The leak can be anywhere. For eg. loose connection between hoses, BOV, intercooler, or hoses and such. If the leak is obvious you will hear a loud hissing sound, and in some cases the engine will be coughing and hesitating, spitting out black smoke out of the exhaust.

Hope that helps.

detonation-coz the air pressure is forced back in to the turbine.which will eventually spoil it..that's wat the BOV is for..release the pressure..! :P

for better trottle response.. a recirculating valve maybe a better way to go. :)
