BOV... Whoosh! Good or bad??, wats up with PSI? Options

[soulshadow]

I've heard that highly tuned cars with Turbos do not make that Huge WHOOOSH Sound cause it takes away all that pressure from the engine. But the way I see it, most people with Turbos tend to install that BOV and make that whoosh sound to let other people know that they got turbos. I mean with the BOV its like a leak in the system where the pressure entering the system drops, but at the same time its meant to protect the system from over boosting and damage. The way I see it, Highly tuned cars do not make that Whoosh cause the user adjusts it enough to make high end power, but at the same time with low end waste of that power. What do you guys think?

a bov has nothing to do with over boosting or anything silly like that.

its job is the help prevent compressor surge from doing damage to the turbo. it also makes a cool noise that people seem to like.

on a map based car (like a 5sfe) .... you can just vent the bov the the atmosphere and have the cool noises without any drawbacks.

on an afm based car (like a 2nd gen 3sgte), when you vent, you loose air that the engine was expecting, and the car can have a crappy throttle response. most 3s owners dont see this as a major problem, and vent the bov anyway, but a proper way to do it would be to recirculate it (but then u loose the sound).

after driving around for a while with the loud hks.... i started to get tired of the loud noise, so i modified the bov so it wouldnt be as loud. now im thinking of going back to the original sound, just because its a good way of telling other ricers out there, whos boss..lol
