Venturi vacuum pump

[sleepydsm]

so basically a vaccum port in the exhaust, lets say downpipe, hooked to your catch can, which will help "suck" out the crankcase pressure.

yep pretty much, the angle on the port determines the "venturi" effect on the gases.

Wasn't this why iceminion was band for a little bit because of promoting his product?

No, he got banned because I paybanned him for being a little bitch about this product.

It just has to be facing "downstream" I think, so that there is a low pressure area around the opening as exhaust flows past it. I think almost any angle would work, except when you're getting close to perpendicular, which would inhibit exhaust flow more as well. 45 degrees sounds good to me. and the nice thing about that is that oil vapors that escape will be burned or at least deposited in your muffler for use later. :)

word son.
Now that i have a welder this could actually happen rather than the ghetto hose to the ground.

One thing that popped into my head about the original design. At idle it is going to be sucking air past the throttle body that shouldn't be going in there. There is a direct link to the intake since the manifold will be under vacuum.

Well I just re-read this thread twice and I don't think I've learned so much at one time before! I vote this most informative thread on style for quite a while. I would like to clear a few things up for other newbs including myself in this situation.

The first pic is of somebody with just a filter on their vc. This is bad because it allows air to get sucked back into the vc.

The second pic is a setup with a simple catchcan/filter that goes on the line from the vc to the intake.

My understanding of the Krank Vents is that one goes on by your pcv valve and acts as a backup making sure no air gets into the vc, and the other goes on a line from the vc to the intake sucking some air out but again not letting air back in. You would also want to use a catchcan/filter on the line going from your vc to your intake.

I'd appreciate it if somebody could edit my post and correct anything that's incorrect. It may be a little late for this post, but I'd like to think I'm helping out some future newbs we might direct to this thread.

Holy jebus, look at all those blue lines. LOL

Holy jebus, look at all those blue lines. LOL

yea i searched for like 15 pages after I saw that because it's kinda hard to see and the blue just hurts my head. Sadly, that's the only car in the first 15 or so pages of tuners that has that little filter on it. 90% of the people just run a line from the vc to the intake. I'm doing this right now, but after reading all this I'm just waiting for a solid conclusion to what I should do.

In order to stop cluttering up this venturi thread with KV-related info I am going to quote and respond to your post in my thread.
