yea, so i found out why my BOV sounded extremely loud lol. I forgot to connect the vacuum hose back up. It threw a CEL after my 2nd drive so i was like WTF looked under hood and realized my stupidity. Is there anyway to eliminate the vacuum line so it doesnt throw a CEL because it sounds awesome

 

done that, i put a boost controller just to proove it didnt work and all i got was wicked compressor surge and 10lbs boost, it closed the plate to lower boost. it was an epic fail.

 

damn, it sounds pretty good when i left it off, but gave me a CEL.

 

i used a manual boost controller and it worked fine. Boosting to 21 PSI.

 

Pics of boost controllers in Cobalts?

 

^^ X2

 

i have over 20 k on my stock spring and it is still good (actually got slightly louded

lol i did the same thing a while back (cry)spiked 21 lbs (off the bat) and held 10

 

lol ok ok guys i will. I will show you where to hook it up to and everything but you must know that i took it off because I am tuning with HP tuners next week. But i must say that i know our cars have the learn down feature but my car was VERY much faster with the Boost Controller. If i was cruising in 2nd gear and nailed it my tires would break loose. I will post pics for you guys tho. It has to be installed in an awkward spot underneath the turbo and ill show you where i installed the actual controller

 

lucky

 

Might want to check this out before you buy a spring that does not do much:

Note what Hahn has to say about that... Specifically post #10.

 

ok here is a pic of where i put the boost controller.

ok now there is a rubber hose on the bottom of your turbo. You have to get underneath the car to see this. Take the hose out and use 2 rubber hoses to run to the manual boost controller. I can post more pics tomorrow if you would like to see this. I will even hook it up for you and shoot a vid of the bost gauge if you're good lol

 

link no work

yea if you could, i kinda want to do this

 

sure man. will do

It never says that the spring HURTS anything for one.

For two it's $10. I can spend more than that on Burger King for me and a friend.

Some of us are just doing a tune and calling it a day more or less. Some stock BOV's are designed by the factory to be of UNEQUAL pressure as a prevention to prevent boost spikes. This would cause a leak by the physical design. Putting the stronger spring in can address that issue.

Anyone doing heavy modding or even light modding with intake / exhaust... certainly those doing turbo swaps I am sure are going to replace the entire valve anyway.

It's just $10... No one has said it would actually HURT anything, just arguing that it wouldn't help... so I don't know what the fuss is.

 

maybe i had the controller in wrong haha ill see if you post pics if i was wrong

 

lol it's ok because i originally put it in the wrong place too

 

every post you make is Bill this Bill that.

Im cool with Bill, but **** you hump him alot

 

so with a boost controller you can run the stock BOV? the only thing it does is add some more sound??

 

no it adds more boost. And yes you keep the stock BOV

 

 

so if someone can give me a quick explanation id appreciate it. I remove the vacuum hose from the BOV, and put it in the boost controller leaving the BOV open?

 

no! You do nothing with the vacuum line that comes out of the BOV. LEave that hose alone

just hold tight for a few hours. By noon Central Time I will show you how to do it

 

oooo, okay. I left it off when i installed spring like an idiot, drove around and was like holy **** for $10 this sounds amazing. CEL came on and i put the vacuum line back on and it got a lot quieter. If i remove the VACUUM HOSE i could cause a major problem correct??

 

no spring = constant recirculation, prolly get stuck open
could close if you boost never tried not physically known.
