Anyone done it yet?
I dont know that much about it other than welding the pipe in at a 45 degree angle should create a vacuum but i really dont know that much about it, like some details, can it be in the down pipe, can it be before the muffler ect. I would like to put one in my down pipe if i can, that way i dont have to route the hose very far, or smell it.
While theoretically, that vacuum principle should work, the issue becomes the pressure that is in the exhaust. This has been proven to be the case, and there has been discussion about it previously, although not here.
Think about it a second. You have all that air that you are squeezing into that motor, needing to come out roughly the same exhaust as some guy in a 7.3 running a turbo back exhaust at 275 hp. Your downpipe will have a much high pressure number inside at full song. So, downpipe is cramped with exhaust gasses, running by the area where the bung for the ccv comes in. That is going to create a turbulence in the air flow, there is no way around that. What that turbulence does, is change the whole air flow of the area, and has been shown to stop the flow of the ccv in those situations. I wish I had saved the link to the well done write up on this.
Why not make a catch can? With all the stuff you have at your disposal, I would imagine that it would be a matter of minutes for you? Or buy one baller
oke: Then, just route it back in between the filter and turbo.
FWIW, I wanted to do the same thing as well. After doing the research, I didn't feel the risk/reward was worth it. Especially with a not-stock motor.
