Somehow when i was passin an old woman i blew the top vacuum line nipple off of the boost bypass valve (the one comming from the s/c to the bbv) I have to go to work tommorow and thats a dealer part that im sure they will have to order. my question is can i drive it without that line hooked up, with my s/c sucking mad air, and still be safe on my engine?

 

just put a happy plug in the vaccum line so it wont suck mad air it will be safe

 

You talking about the bypass silonode or the bypass actuator?

 

Order it through zzp...... not expensive and plug the vacuum line,up but dont drive it alot becuz all u r doing is running straight air all the time through the supercharger because its not bypassing it. Unsafe meaning.highh iat2s..

 

pluging the vaccum line is no different then the boost bypass and will not raise iat 2 and the one that zzp sels is for the m90. eaton told me that it woud not function properly on a a m62 due to the higher spring pressure inside of it

 

if you pay attention when you order the bypass valve you can see the area to scroll down to get one for a cobalt/redline, i just bought one....

 

This.....

Ordered one from them a while back.

You might wanna go ahead and replace the 2 hoses while your at it if they look cracked mine did.. since your already diconnecting them.

 

Be smart.. plugging the vacuum line Will not let the vacuum line suck in atmospheric. Air in causing a vacuum leak. Second with.the vacuum line.not.connected to the bypass it causes all the air to go through the s.c causeing hotter air. So in the outcome. HiGHEer IAT2Z

 

yeah im not gonna mess with it, the car is sitting right now waiting for my package of goodies from zzp, i am gonna replace the rest of the lines too, they are pretty cracked up.
