Understanding the CCV mod?

[krupatex]

The true reason for the ccv mod is to what???

[njjeep]

its to eliminate the oil that would go into your turbo and boost tubes (which usually leak out oil and can make the boots blow off).

[krupatex]

how would this effect my performance????

Well for one, the thing that routes your blowby into your intake is VERY restrictive of air flow. Probably blocks off 20-30% of the intake tube.

Take off one of your boots and then tell us what you figure out.

[Tikal]

That too... It's heck on intercooler boots...
Just unhook the hose between your air filter and the valve cover, look at that thing protruding and that's enough to wanna jerk it out

right on man I do know what your talking about, but didn't know it restricts that much air flow. i just took off my intercooler inlet tube and WOW! That's a lot of nasty sh#t in there! Do you know of any good CCV mod posts for how to DIY?????

I run a closed system ccv mod and had to keep the stock piece that supposidly blocks 20% of the airflow. I have a hard time believing that it blocks enough to do anything. They also say the AIH blocks 20% of flow as well. I took that out and it obviously made no difference. So I guess what im trying to say is I dont thing that CCV piece in the intake tract takes any performance or airflow away. one could always just trim that little lip that sticks up in there if they wanted to.

If you think it is not restrictive you don't flow enough air.....LOL.... I will tell you this, if you tow heavy a lot, getting rid of that CCV block it will drop the EGT's a little since the air flows much better. Plus the oil is not blowing the intercooler boots at 23psi pulling grades.

Do some dynamic flow testing on the system with and without the CCV POS restriction in it. All I can tell you is my truck flows 1770cfm through the filter heading into the turbo under full boost. Anything in the way will restrict that much air flow so I don't want anything in the way. That is just my $.02 worth on that.

hmmmmm. I will have to trim it flush then tomorrow when I put my new intake on. And I dought Im flowing half as much air as you strokin!! lol Im just a stock guy
