RE: BOV, boost & air intake question
1. You do not have a BOV on your car stock. Volvo has what is called a CBV. Kind of like a BOV but isn't.
2. If you add a CAI to your car, you will hear the turbo more yes.
3. There are not real Volvo specific applications for BOV's. Just get a universial one like an HKS SSQV.
4. I do not know if it will void your warranty or not.
5. I don't know exactly how much boost your making stock, but I would say between 5-10 PSI.

No matter how cold the air coming into the turbo is. It will always leave the turbo the same temp. Just drop in a Kand N filter, thesse seem to yield good results.

Will the filter do ne thing really. are there any power gains at all. will anything "get louder"weither it be the spool of the turbo or the bov??
thanks

RE: BOV, boost & air intake question
take off your hood insulation and get a CAI if you want more noise, the spooling of the turbo as well as the pshh of your Compressor Bypass Valve is much more audible. And a CAI really does nothing for the car, I almost want to say it's the placebo affect when you install one, expecting a change when really there isn't. Throttle response did seem to increase a bit though.

So is there really no cool air intake out there for the Volvo that will make a reasonable impact? It just seems like there are 1 MIL different after mods for Hondas, Nissans, etc......but apparently only like 5 for the Volvo.......

Yes there is tons of things for Hondas etc... However Volvo's haven't been reaserched enough by the aftermarket communit to really get items massed produced. That is another reason why Volvo aftermarket items are so exspensive.

It's important to note also that for there to be any real gains from an after market intake you need to address the throttle body, adjust the valve lift, maybe get a higher cam, do a little valve cover grinding, port and polish your exhaut header, and install some kind of Cat. back exhaust system. To do this on an engine that already has a turbo? I'm not sure you'd be improving matters at all. I would think messing around with the header alone would cause some kind of problem with your turbo. BUT, on an N/A engine and with all that modding a WAI or CAI could potentially give you another 10-12 HP......or rather, with all that modifacation and no aftermarket intake you'd loose 10-12 HP of your potential....
...they do sound cooler though....I threw a WAI on my Cavalier and it sounds fast

how do you figure volvos don't have exhaust heads? Maybe not in the aftermarket but in the true sence of the phrase every internal combustion engine has an exhaust head of some form.

Generally it seems to me that stock it is referred to as an 'exhaust manifold' and then called header(s) when theyve been changed out to something that is a little more directed and less restricted.

Even with you upgrade to a better manifold it is still called a manifold. "Log Manifolds", "Tubular Manifolds", Etc...

RE: BOV, boost & air intake question
A header IS an exhaust manifold. The reason it's called a header vs. a manifold is becasue a header uses equal length tubes to vent the exhaust whereas a manifold does not. Bering that in mind....I used the wrong word. However, my orginal point being...porting and polishing a header/manifold for a turbo set up on a Volvo probably would not benefit the system. As such (and to get back to the point of the post) an air intake of any kind will not do much if anything. You're only changing one of many things in the breathing system of the car and I don't believe the air intake is the weakest link in that chain for a Volvo.
