It is just the way the valve is. I couldn't find this post previously when I talked to Forge about this and I was told the valve could go either way and it makes noise sometimes whewn it is installed one way on some cars. Just the way it is.

 

Are you guys just buying BoV's for sound? hehehe... dont get me wrong, i love a nice sounding bov... :-) mmmmm...

anyways, i found this online the other day, i thought i would show you guys who need even more sound!!

Electonic BOV :-)

But seriously, I ran open filter for a few days and noticed a power loss... sound went up but power went down. I dont think its a good idea to introduce new air (including enginebay's hot air) without balancing the fuel rate or CPU, this is just my humble opinion.

Im holding off until i do everything else... enjoying my stock quietness for now :-)

 

very sweet. btw i dont think you would be able to feel a 5 hp gain. which you might be getting from that short ram. but im sure its there but too little to notice

 

OMG, just when you thought you'd seen it all. (rice)
Electronic BOV LMFAO

 

ehhehe, yea ...funny **** - i wanna buy a few and give away for christmas...LOL

 

Best part is the price. $350 for a fake BOV

 

I really really need all the help I can get. I currently have a Forge BOV and RMR Air filter Kit installed. I don't know about the rest of you but the two together sound like absolute ****!!!! I went ahead and installed the BOV two different ways and the sound was always the same. There is never just one big release of air, rather there is the loud disgusting and annoying sputter of pressure being released. Is anyone else experiencing this problem? I mean, sure the BOV is much louder with the air filter installed, but damn the BOV never ever sputtered like that. Can anyone comment on what is going on? Otherwise tomorrow I'm putting the stock air box back.

 

Whoa.. The stock air box is only going to mask the problem.
There is something wrong with the DV. It should release all at once and be nice and smooth. No matter how much boost I am releasing it is always a nice woosh. You either have a too stiff spring in the valve or the valve is defective. Put the stock BOV back on instead and get a hold of Forge. I am sure they will take care of it. You did get it from forge, right? Reason I ask is that a vendor may have sent the wrong valve.

 

Chances are if you install the other way, it will squeak, which is more noise but it is hideous and annoying. You won't hear it unless you have an open element filter like a cone filter (RMR).
Check out this post for more information on the Forge valve and what I found. https://www.evolutionm.net/forums/sh...ight=Stock+bov
The forge valve works differently then most valves out there. The whole post is good information, the Forge info I posted is at the end.

 

I have the RMR intake and the stock BOV. It sounds great. The intake made a little more power (that's why I added the turbo-back exhaust), but it really does wonders for the noises under the hood. I am not really sure I need to upgrade the BOV unless I increased boost pressure (which I'm not going to do).
