I think that just before the supercharger, the air is less dense than atmospheric, but will be affected by stacking that may occur due to a roots supercharger taking somewhat discreet gulps, and other obstruction-related slowing. The air travelling down the inlet duct will be less dense than atmospheric. Pretend you have a line of MINIs doing a rolling start as they cross a starting line. This line of cars travels at five miles per hour until they cross the starting line, then, upon crossing the line each car accelerates to some higher speed. The line of MINIs began with a "density" of ten MINIs per 100 feet travelling at 5 MPH and ends up with a "density" of one MINI per 500 feet travelling at 50 MPH (numbers made up, not calculated, but you get the drift).

Just one more loser like you that I can ignore from here on out. No biggie.
I see you pussed out on the argument about superchargeres creating vacuum.
At least you were decent enough to bow down before your betters.

OK, 229 posts and I *still* have this question:
I installed an M7 OCC as per the instructions, including capping the grey "vacuum" line from the SC. After 4 months there's not a drop of oil in the CC, so should I revert to stock? The OCC doesn't take up much room or present any real downside to under-bonnet access, but is it harmless? Some posts suggest that capping the grey line is *bad*.
Can we get some answers after 200+ posts?
thanks,

And it would be air over a curved surface. A flat surface would demontrate no pressure differential between upper and lower surfaces.
But hey, what do I know.
Helps a ton with carburetors though. And those in the air wingy things

thanks for letting me know how Bernoulli's principle helps with the wingy things. I really do not think they had wings to work with in 1782

****Bernoulli's principle states that in fluid flow, an increase in velocity occurs simultaneously with decrease in pressure. This principle is a simplification of Bernoulli's equation which states that the sum of all forms of energy in a fluid flowing along an enclosed path (a streamline) is the same at any two points in that path. It is named after the Dutch/Swiss mathematician/scientist Daniel Bernoulli, though it was previously understood by Leonhard Euler and others. In a fluid flow with no viscosity, and therefore one in which a pressure difference is the only accelerating force, it is equivalent to Newton's laws of motion. It is important to note that the only cause of the change in fluid velocity is the difference in pressures either side of it. It is very common for the Bernoulli effect to be quoted as if it states that a change in velocity causes a change in pressure. The Bernoulli principle does not make this statement and it is not the case.****
DialM was stating that as velocity increases pressure decreases and in a tube I think that is correct.
I see no wing or carb in the above picture.

It is not like the atmosphere is pushing all that air into the supercharger.

i wasnt involved in the argument, all i was doing is explaining what the catch can did, and put some pics on the forum. your the one who really got involved with the vacume thing. i hate that fact that YOU of all people think im a loser because i really do care what you think...i really do.
oh and you better keep your promise about ignoring me!
(i thought name calling was for third graders...well i guess it still is.)

It is not like the atmosphere is pushing all that air into the supercharger. The issue was never whether or not there was a pressure differential. The issue was whether or not there was a measurable vacuum in the supercharger inlet. You seem to be choosing to ignore my question:

Can you explain this, or offer some evidence supporting your assertion that a supercharger makes vacuum at its inlet?

obehave,
Don't waste your time with those stupid e-wars... I'll always respected you and I know that you're a MINI king.
btw, I've seen your races movies and I must admit that you know how to drive! Awesome driving skills and knowledge.
Let the kids in their playground and don't waste your keyboard's keys on them.
My 2cents...
Now, back to the topic, does anyone has a detailed (with pics) how-to on installing an OCC ?

Which OCC and where do you want to install it?
Here's a link to how I mounted mine. There were some issues I corrected with the mod I did but I like the location. It sets below the valve cover vent so any drain back is eliminated.
For now mine is single sided and returns to the gray line that is being debated here. Based on some of the, on topic, questions raised in this thread I'm going to revisit the routing. My OCC does trap oil but I have also found that some still collects in the IC. For one reason or another I have the IC off at least twice a year so keeping it clean isn't an issue.
I do want ot see if I can get the OCC to do a better job.
It's a GT Tuning piece BTW. Very nice. Not cheap but it was a tax return gimme from a couple years back.
If you get no good responses feel free to PM me and I'll do what I can.

Someone pissed in his Cheerios and he was the one who started the belittling about spelling and supercharger knowledge. Also if you look back at page one I was the one who was most interested about the OCC and how Arly installed them, brother I was wanting to learn.
Then he had to be a complete **** towrads Malcom....who I do not know. This is how this thread got to this point. So go back and read ALL the pages your hero wrote.
Also I am glad you put obehave on a pedestal and just by the tone of his postings that is just what he needs. I do not care if someone is the best driver, mechanic, or whatever in the world....if you show no respect towrads others, belittle, and have zero humbleness that person is crAAp in my book and I will have zero respect for him/her!
WHY the mods have not shut this thread down is beyond me!!! It is so far off-topic and some threads are just down right badgering.......yes and like mine.
