Let me guess the bigger the louder right??? and is 50mm big?

 

not sure what you are asking i know the size of the blow off valve but there isn't one for the ss/tc

 

There is, but it’s a recirculating and not an atmospheric...

OP, see this thread: https://www.cobaltss.net/forums/2-0l-lnf-performance-tech-153/new-2008-cobalt-bov-111567/

 

well yeah but that we have a recirc valve not a blow off different things, but yeah... Hahn has a setup for the solstice maybe they will come out with a conversion for the ss/tc

 

Yeah I am planing on Twin Charging my Cobalt and I want a loud ass blow off valve. The turbo is going to be a Bullseye 57mm V-Band Turbo with extended tip. its a T3 5 bolt V-Band type. The package offers a 50mm BOV.

 

since the ss/tc bov is a recirculating bov,cant you just block off the port that recirculates the air back into the manifold?the sti's have the same thing.u block the port off and u have a bov that shots air into the atomosphere

 

Are you talking about twin charging an LSJ or an LNF? I am going to assume LSJ...

 

this thread is full of awesomeness

 

lolol^^^^

 

i agree hahah

 

You can't block off the bov and vent it to the atmosphere because the car is expecting that air to be there and if it isn't that results in danger...........

 

Yup the LSJ.

 

just an fyi. size does not determine how loud the bov is. the size is for preventing surge and is matched to the turbo's output.

 

Wrong section! But good luck with your build!
