BOV recirculation????

[GSEclipse620]

Hi everybody
I've looked on a pant load of BOV forums already and can't find anything that actually explains how recirculation works and it just seems beyond me.
To start it out let's just clear up what a BOV does: it clears out the air between the turbo and the throttle body, this lets the turbo keep spinning and not hit a wall of air which would force it to stop and damage it. Is that right?
Now if i was to recirculate the vented air,, where would i be recirculating it to exactly? If i was to put it back into the intake system wouldn't that just defeat the whole purpose of a BOV in the first place?All the pressure would still be there and cause the turbine blades to hit an X psi wall of air causing it to stop. Do you vent it past the throttle body into the actual intake manifold? If someone could answer this in detail that would be great. Also, my friend has a 98 GSX and i've only scene the inside once since he's at college but his BOV is venting to the atmosphere. Did he do somthing different or is he just getting horrable gas milage? Thanks fellas

The air comming from the BOV would act just like air the turbo sucks in through the intake. If the BOV didn't open the air would come back through the intercooler piping and try and spin the wheel the other way. That is what compressor surge is. If he doesn't have some sort of blow-thru setup that is setup not to calculate the air that is supose to be comming from the BOV, like a stock ECU would do, then it would net bad gas milage and unsteady idle when you get off the gas and let it try to idle. Might even die at time's. It should be recirculated back into the intake pipe.
