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?

My car (1.8T Jetta) uses a diverter valve, which just diverts (duh) the air back into the intake stream when I let off the throttle. The stock valve and setup doesn't make much noise but now I'm running a Forge 007P piston-type valve (opposed to the stock diaphragm-type) with an AEM CAI and its very very loud. I scare people on the side of the road when I drive by

The point: the whoosh isn't good or bad in itself-- just make sure you do what's right for your car. Some people with 1.8T's use BOV's and end up putting themselves into limp mode or making their cars run like crap since we use a MAF sensor.
