I love how a 42R looks in an our engine bays.. its like Intimidating but yet sexy at the same time...
but anyway.. to stay on topic. having an 0/2 dump should still pass emissions though rite? because it doesnt actaully open till full boost.
Where y'all get the money for them huge a$$ turbos? Beautiful setups guys, I'm slowly making a fund for my car. I do mean slowly.

If they hit full boost with my car while doing that, someone would get fired.
An o2 dump will pass emissions if it has a catacalysmic device on it. Which defeats the purpose of doing it Id say. So, no. Your going to fail any visual inspection with that. Especially with an externally gated turbo. Unless you could hokey rig some lower heatshield from the stocker, and make sure your car isnt dyno tested. AWD would have the only way on this.


That's interesting....the turbo in the pic I displayed is a Frank Level 5 20G on my buddy's TSi AWD. That dump doesn't make a sound until 22psi is made, and when it does open you know it.
If yours begins to dump at 10psi, something's wrong with your wastegate actuator or the way the flapper's sealing. You shouldn't hear any exhaust coming out of the dump tube until you've reached your target boost level.
How about running open DP instead of buying an o2 dump? Going to be loud as hell, and will get you pulled over alot, but who cares right..
