I just got a BOV for my s60 2.4t and when I look I see that they are not placed where the CBV is now. Do I put the BOV in the same spot or do I have to cap the hole where the CBV is to add the BOV?

Thanks!

WElcome to the forum.

Best place for that BOV is back in the packaging it came in. Seriously not a good idea on these Bosch ME7 cars. The EMS does not tolerate BOV well at all, more trouble than it's worth by far. These cars utilize a Compressor Bypass Valve that recirculates the excess pressure back into the intake post MAF to prevent altering the air fuel mixtures.

So you want the car to go "whoosh" right, to let everyone and their mother know you have a turbo right? So best way to achieve this is with a cone filter in place of the stock air box. If you want louder, more complex venting noise than the stock CBV you can try a Forge piston type CBV like I have.

Hope that helps,
NJGB

That's what I did: Cone filter, Snabb Pipe, Forge CBV, Hood liner removed, rubber rain seal removed and hood vents installed makes for a very loud accelleration and venting noise. And ME7 is happy to boot.

This helps alot! thanks for the advise. Where would I get a forge CBV? and would you recommend completely removing the airbox, or should I keep the box in and just take off the cover?

Install a snabb pipe hose and some cone filter and you will love how this engine+turbo sounds.

ok, is that the full intake or just the blue hose piece in place of that section of the stock intake? Also does boost go down as the years go by? if so how do I regain back to the original 8 lbs.

You can get the forge cbv from here http://www.ardtuning.com/HP-CBV-replacement-for-TD04-turbos_p_76.html. As far as the intake its a full intake goes all the way back to the turbo. It can be bought here http://www.snabb.us/Performance-Fresh-Air-Pipe-01-09-S60_p_86.html

By boost going down what do you mean? Do you have a boost gauge hooked up to monitor boost? If so whats the vacuum number at idle and what the boost readout at top end? If your experiencing lost boost replacing the cbv would be a good start as well as getting a new turbo control valve (tcv). Snabb and Ard both just came out with one, basically the same tcv just different names on them. you can still buy it for sale pricing at snabb i believe http://www.snabb.us/Snabb-Precision-TCV_p_134.html. You will also want to check for any boost leaks this can cause a loss of boost.
