turbo/BOV noob
I’m very new to a turbo car. The 04 WRX is my first car from driving an old beater. Since I am still under warranty I do not want to do any major modifications to the car. I’m trying to salvage any extra money left over from payments to do my first mod. I was considering a BOV just for the sound, my question is what does it do to the car? All I know is it releases more pressure faster then stock. What does it do for a stock turbo? Some people say putting a BOV on a stock turbo will make the car not run as well. I am also planning to get a exhaust in the far future.
It does absolutely nothing for the performance of your car except add sound. In fact you may even lose a little power, because your turbo will have to spool up to create more pressure in the intercooler that it lost to the atmosphere creating the sound. Hope that helps ....

i've heard BOV extending the life of the turbo? but u make it seem like the turbo has to work harder????

On the stock turbo it won't do much. On bigger turbos with higher backpressure, a bov can extend the life of the turbo.

It'll make your car run rich = waste more gas. And sometimes an aftermarket bov can cause idle problems.

I don't think you guys are understanding what I am saying.
1. From the factory the car comes with a BOV, it's just not venting to the atmosphere. Unhook the recirc hose and viola.
2. The BOV reduces compressor surge which extends the life of the turbo, that is it's primary function, not to help the turbo stay spooled. This just happens to be the effect of having a recirc hose that plumbs back into the intake track. This is only done for reasons of keeping the originally metered air in the system.
3. In the end, running a BOV to the atmosphere to get a sound has nothing to do with performance. If you're not interested in performance and want that sound, great, I could care less.
Bottom line: If you want to keep your car running at the highest level of quality, performance, and reliability that you can, don't vent a BOV to the atmosphere.
I am finished

This topic never gets old with me ...
turbos will have to pressurize the IC with a 100% atmo? ROFL
So wait? just by adding a bov I'm going to be dumping more fuel all the time? AWESOME! MORE POWER! TURN UP THE BOOST!
its depressurized air ... almost instanstly. at which point your motor is sucking air and your turbo isnt pushing anything because your foot is still on the clutch thus the only load is the engine. You wont make anything until you release that clutch and the system is closed with load on the engine.

It just redirects the boost right back to the intake, so that the turbo doesn't have to work as hard to extract air.
