yeah man, no problem. i felt like i was in first grade again...who cares if somebody cant spell...ha

anyway are you getting a catch can soon?

 

Yep, we are wanting to add the can in a few weeks. First we want to get past the break-in period, then we will start dropping in the mods. I do not want to have to worry about cleaning it out, just want to stop it before it happens.

But before anything the Mini needs to come off the blocks...we are getting some wheel work done that was only supposed to take two days....it is now going on three weeks!:impatient Lucky for me Pep'r also wanted this work done or else she would have killed me by now.

 

OK pilgrim, you better listen and you better listen tight

 

I'm listenin'

It was that new Robert Duval movie; Broken Trail on AMC.
Real good.

 

Whatever, superchargers don't make vacuum.

And I don't know how you got your A&P whatever that is. Hopefully it has nothing to do with superchargers.

And I did add something to the thread. I pointed out that you and your sarcastic bud don't really know what you're talking about.

Just a friendly public service to those that may be under the impression you know what you're talking about.

This is fun... do continue.

And in this corner

 

 

obehave tried to live up to the name, but you had to wake the sleeping giant

 

Really? Then however does the air get in them?

 

am i in kindergarden again...this forum is very black and white. you have the guys that know "everything" and you have the village idiots... everybody is right and wrong... i thought this forum was about enjoying our cars and haveing a good time talking about them and how we could make them more personal. its like all this is about now is who is right or wrong, and how there is one way to do somthing. i think some of you should get off your high horses and just have a good time. WHO CARES if i spell poorly...is this an english forum? i could see why you would have grounds for saying such things on that forum...but not here...you just a kid who needs attention. and if you arnt then your doing a great job of playing one.
i guess ill quit ranting.
oh and 62Lincoln, thats funny. (the popcorn hehe)

 

vacuum or boost (+/- pressure) can be measured between two points, so say if the supercharger itself is in a vacuum state, the pressure at the final point (SC outlet) is less than the pressure at the initial point (SC inlet). The same thing can happen to a NA engine, and is usually caused by the throttle bodies closing. Although there is a vacuum state within the engine, the SC is not actually "creating" it as such. All a SC can do is create pressure above atmospheric, otherwise known as boost.

 

I'm not the one throwing my rattle out of the pram

I said a few posts ago I was ready to let this go but you just have to keep piling on and then you get whiney when I don't let you slap me around and do nothing.

I don't know everything and actually don't pretend to. I do know enough to listen and learn when others tell me I'm wrong. Try it.

 

Magic

 

ok now you can go away.

 

All this talk about the correct English has gotten me interested.
Are you an English teacher in real life? I'm just curious, please don't be offended.

Take care,
Leo.

PS: iZ eet jus mi or jou phorgot da period? Tsk, tsk...

Here's an easy thing you can do to prove wether or not the line that runs from the upstream side of the supercharger to the one-way valve on passenger side of the valve cover ever "pulls" air out from the valve cover. Disconnect the one-way valve and ensure it is truely a one-way valve and air flows. Once you're satisfied that it flows in one direction, disconnect the hose to the valve. Start the engine and let it idle. While it is idling, place a moistened finger tip over the hose opening to feel what it is doing. Let me know what you find out!!


p.s. I already know the answer.

 

I forgot, what was the original question?

 

.

 

That is funny something you do not know. A&Ps are the ones who are certified by the FAA to work on the aircraft you and your family fly on. But lucky for you I only fly them. So telling me I do not have turbocharger or supercharger knowledge it right on. Also when I am making position reports durning an Atlantic crossing at 3am they really do not care if I know how to spell.

It is my understading that when you are producing boost and the moment you come off the throttle there is a moment where there is vacuum. If I am wrong then I am so sorry to have made you go through all this. Isn't this the vacuum reading we are getting on the guage? Of couse the job of a turbo or SC is not to produce vacuum.

Your postings have a real crAApy tone and that is why I posted what I did towards you. It was a very unnecessary attack towards a member that was just trying help! But in your mind you thought different! One would think after posting on other forums that I would be used to members like yourself but for some reason I just can not build a callous........you are a real asset to the Mini community.....keep up the great job!

Aren't these Minis supposed to be fun?

 

well some people feel like they need to make a name for themselves. this can be a good thing if the person is trying to be helpfull, or kind in general. its a shame when the name they make for themselves has everything to do with poor character and lack of respect for the feelings of others.

i also think there is a lack of moderation on this site, members like this should be told that they are out of line and if they continue, then there should be consequinces.

also, the members who are in essence fueling the fire "in this corner, popcorn etc etc etc" your just as bad on a level. i think maybe you are afraid of the kid, and stay close to him so that he doesnt think your a lesser person.

and i still dont understand why there is just a few of us who agree that the kid is out of line.

 

etalj, that is also my understanding. Sorry to everyone if my wording in the earlier post was not correctly conveying my thoughts.

 

This was the start of the thread and I just want to personaly apologize for the direction it has since gone Arly.

Thank you for taking your time and sharing the pictures.

 

Still here

 

I didn't "attack" anybody. You pretty much started that especially with the name calling and what not. Which you are still doing even though I once again in my last post said enough is enough but hey if you want to keep going, well, be my guest.


That aside. The vacuum is just a function of the nature of internal combustion engines. NA cars draw vacuum don't they?

Another point for clarity as well. I am speaking about the Eaton unit on the MINI, nothing else. Some of the statements here and in other threads reference turbos. Totally different method of producing boost and differences in induction path.
Roots/Eaton units build boost through resistance post supercharger.They do not generate boost internally like turbos or centrifugal superchargers.
Factoid: the Roots blower was originally designed as a fan for pulling air out of large buildings.

The bypass valve recirculates the excess boost after throttle shutdown. It also regulates boost under high vacuum conditions. Example, highway cruising.
The existence of a vacuum condition is just the normal "breathing" effect of an internal combustion motor. Like I said NA cars draw vacuum constantly while operating. FI exists solely to create boost or conditions above atmospheric. It's what they do. They cannot by their very design create conditions below atmospheric.

DialM earlier in this thread jokingly(?) said "Really? Then however does the air get in them?". Funny but not accurate. Place a Magnehelic or any vacuum gauge in the intake tube ahead of the throttle body. You will not find conditions less than atmospheric. Post throttle plate you will start to see lower pressure conditions. Put your hand on the end of a vacuum cleaner hose, what happens? That's why you pull a lot of vacuum at idle. The supercharger at this point isn't doing much of anything. Highest vacuum when the supercharger is doing the least work, hmmmmm, just like an NA motor.

Contrary to your assertions I am not a know it all. I come here solely for the purpose of learning from people that know so much more than I do I feel retarded on occasions, frequently really

I was asked to clarify what I was joking about in my first post. I did so, honestly and without malice. If your impression is otherwise I really don't care. I know the reality of my intentions.
Does that mean I'm supposed to back down from some bluster and chest thumping? I don't think so.

If you want to feel better about me saying some stupid sh** and getting busted on it. Read the IC cleaning thread.
Maybe you already have.

 

Since the popcorn was my contribution, I'll respond. The popcorn icon is accepted to mean "watch the show", without picking sides. Sorry if it offended you, it was not meant to be a barb at anyone, more an attempt at levity.
