Venturi vacuum pump

[iceminion]

I guess I should have been more specific about the applications for this pump.

stock cars with stock intake pipes are probably going to be ok.

cars with 4 inch intake pipes coming off the turbo have a problem.

Since the 4 inch intake pipe is such low restriction, there is absolutely no vacuum created by hooking a vacuum line up to the side.

I tested this with a boost gauge, didnt pull any vacuum at all.

again, this is for people who are having problems, if you are not having a problem, nothing to fix right?

Where did you place the boost gauge vacuum line? I'm wondering if it is placed directly in front of the compressor housing if it would work? I want to make crankcase vent system for mine as well. I'll play around with a thing or two and if anything works, I'll let you guys know.

yes, I lost a bet with one of my gearhead friends, believe me, I was of the opinion that "this is a crazy idea and will not work"

Lets put it this way, I had the car setup just as it was stock, the turbo pulling on the crank case vent, I had oil leaks everywhere, but due to the (massive) change in diameter of the intake pipe, the stock vacuum line did not pull much(if any) vacuum, and I HAD OIL LEAKS.

all I am saying is this FIXED THE PROBLEM that I have always had, my first TSi AWD (stock) popped the dip stick all the time, and when i let my friends drive the car it would pop and send oil spewing up onto the underside of the hood, make a huge mess of things! I wish I had this then!
