My car went fast before & is fast now, but it makes cool noises when I shift. Plus it adds a lot of ooh & ahh factor when you pop the hood

So many not knowing newbies giving false info!
The rear one is the charge relife valve which is only opened during #2 turbo prespool. It is located on the rear half of the "Y" pipe assemble. The reason it is only open during prespool is to allow #2 turbo boost to escape to atmosphere.
Why, because boost is prevented from going to the IC by the charge control actuator which is also located in the rear half of the "Y" pipe just befor it couples with the front half. After prespool, the CRV closes and the CCA opens.
I'll let let learn on your own about the TCA.
It would be nice if you-all understood how your systems worked!

Wow......look at the big brain on brad.
Bottom line? You can use a BOV as a CRV....... OK, so don't start gett'in all uppity on us.
Besides.....it looks cool.........ooh.........ahhhh
You can stick your head up a bulls *** to get a good look at a T-bone steak, but Id rather take the butchers word for it.

when does the CRV actually open then, just at the transition point? do you get a blow off noise as it travels through the rpms then? if that is the case

It keeps the turbo from stalling while the flapper door is closed. Thus not gay, and very important to turbo life. Come on Pugg, I figured it all out just by looking at the vac hose diagram...

While the valve itself operates like a BOV, the operation it's used is different.
