lol. Well, I'd be down for a GP on some cheap industrial check valves that we can rig up ourselves. Does anyone know of a website for something like that? |

I still have 4 left from my mod!!!
It was cheaper to buy a pack of 6 then it was to buy 2.
I will find the website later and post it in a different forum and show the proper way of hooking it up (with catch cans!)
One key thing is that you still need a proper working PVC valve with this setup i believe.

Re: Venturi vacuum pump
Is there a 1 way valve on the line from A1 to your "venture" (brass T) devise? If there is this setup would not work any better under boost then stock. I do not see it working better then stock at all, you said your self the intake pipe does not make any vacuum. Also if you want to hawk your crap to the masses here contact scheides and set up a vendor account, then you will not be banned at least. If you really want a vacuum on the crank case then a mechanical pump will work better then any setup you buy from Ace Hardware.

Re: Venturi vacuum pump
Wouldn't those check valves at least be better than OEM?

Yes. Most factory PCV valves leak boost into the crankcase. I actually now have my own brand of these Krank Vents that I am testing out on my car and Scheides' car.

LOL hell yea!
I've been a fan of Krank Vents for quite some time and I used them on my S2k with great results, but I did realize they are really expensive for what you're getting.

Re: Venturi vacuum pump
There is a place near my house that manufactures check valves, I should check them out! www.specialtymfg.com

Re: Venturi vacuum pump
i have mine setup the same way yinyang does, and get the same results i was gonna weld a tube into my exhaust to create suction at all levels.
I was reading a post on some other site about doing it, apparantly a lot of people have been doing that for a long time.

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

Re: Venturi vacuum pump
yep pretty much, the angle on the port determines the "venturi" effect on the gases.

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.  |
