The engine is trying to breath when the car is running, so you put your entire hand over the inlet of course its going to feel that way. You can stop the turbo from spinning and it will still try to suck your hand in. Im not saying the turbo doesn't help but the point of reference is not good. Remember that the turbo wont "pull" any airflow that the engine doesn't also ingest. Unless its leaking out somewhere.
The tube is connected via air filter to the atmosphere a short distance away; this automatically means the atmosphere will ALWAYS be "fixing" any actual vacuum you start to build in the tube.
the ONLY way to tell what vacuum you have there is to install a gauge. It doesnt matter how big the tube is; only the pressure inside the tube matters.
And I think you are going to need to measure the vacuum in Inches of water, not mercury or PSI. this would be a great experiment wouldn't it? because I dont think anybodies actually done it. I might try to set this up once and for all. I am thinking a 2L coke bottle filled with water, with marks up a long transparent tube connected into the turbocharger inlet would do the trick.
Lol I might be headed to wal-mart tonight because I am insanely curious.
