Cobalt SS 2009 TC

Can someone explain to me what this is and what does it do. I am guessing it replaces the back plate on the bypass valuve.

Eliminates the OE Recirculating Bypass valve to use an atmospheric BOV

In normal terms for half the site..It allows you to cover up your stock BOV hole and then you can run a "real" BOV so you can have sound. No real gain.

that is a common misconception. No it does not throw a code.

Mazdaboi318

so what is the purpose of the delete?

kling1022

because you need the vacuum hose from the BPV to put on your new BOV.

Mazdaboi318

hey kling how you enjoying that muffler delete?

kling1022

oh man i love it it's great. Best thing i coulda done.

so what would this do on a stock balt?

kling1022

ummm no you need a BOV on the intercooler piping for this to work. Otherwise to you are going to take your BPV away. You need intercooler piping with a BOV flange and then buy a BOV valve. Use the block off plate then take the vacuum hose from the BPV and put it on the new BOV

mmmmm compressor surge.

i just cant wait for hahn to start making there gt30/35 turbo kit so i can do wastegate!!!

kling1022

no compressor surge if you get the synapse engineering recirculating BOV. That sell them at TTR. You should check it out

Since when does a bov cause compressor surge?

HackAbuse

My comment was directed at a lack thereof (with the installation of a BOV delete)

You live in Buffalo and BTF (in Honeoye) is making a GT30/35R kit using my car as we speak..I'm getting the car back next week..you should go to him since your close

The turbo would **** it's self if it had no where to release pressure.

Also known as Compressor Surge.

surge= bad boom boom= driver

The gnx never had a bov, granted it was auto but still.

if your staying on stock turbo you wont want a vent to atmosphere BOV... Youll lose unaccounted for air thats supposed to make its way back to the sensors, car may bog after shifts, I had a BOV on my wrx for a half hour before it went on ebay/forums.

If your going aftermarket turbo, and or different e-management thats a whole different story

Matt M

Regardless of what turbo you run, you can't run a BOV dumping to atmosphere with the MAF before the turbo. If you want the BOV sound, the MAF will have to be moved.

kling1022

fail! not true many people have done it and are running fine

Matt M

"Running fine" leaves a lot to interpretation. Sure you can make it work, but it's certainly not optimum. You will have an over-rich condition when the BOV releases air that has already been metered by the MAF sensor.
