"O2 dump?"

[Mr_Ginzo]

i've heard this term being used in the past, what does it mean?

By using an o2 dump setup, when your wastegate opens it will vent the exhaust that flows through the wastegate downward and not through the exhaust system. A setup like this is used to better regulate boost, but is very very loud at wide-open throttle.

ah sounds like an external wastegate correct? and pretty much does the same job as a "dump tube" thats not recirculated, i get it. so i could run a 02 dump on a 16G?

Plenty to read up on here.

Yes, you can run a dump on the 16G. It will help with creep as well. But, it is very loud and may not pass inspection in certain areas. There is not much, if any, performance gain unless you are still running stock exhaust. I ran one for a year or so, then finally got sick of the noise and went back to recirculating it.

It is very loud when the wastegate opens up! I actually got scared the first time i heard it in my car and thought i broke something. . The one thing that it helped with tho was after i installed it, my boost never spiked past what i had it set at.
