the intake manifold is the bottleneck,
and porting the SC is useless because maximum displacement per outlet has been achieved
whether u put that supercharger 10,000 feet above or below sea-level changes nothing. Yet you insist i backtrack on something that has nothing to do with the topic at hand.

Thats like linking an underwater pipe pushing oil at 10000 PSI when it is under water at 120 PSI.
How is that linked?

I said oh good lord, because you keep back tracking and changin subjects
yes because apparently the school system rrutter went through focused more on changing focus of a topic to avert the attention of him being wrong and not actually learning

What was the original thread about again?? I am feeling a little lost here. I admit I am a "newb" at all of this. I hope name calling is not required to "win" a point here, whatever the reward for that is..... Let's see if it makes sense to someone like me. If you smooth out the S/C passages, or inner surfaces, you enable the S/C to work more efficiently. Does this create less turbulence? Kind of the same reason for upgrading the exhaust. It becomes more efficient allowing more air to be pumped into and out of the motor, correct?
I might not be creating more HP, but am I allowing more "potential" HP? The air temps drop, and the air is more dense, correct? So, is this another benefit of polishing? Not sure about porting yet. It seems to me polishing the S/C is at least a decent supporting mod. Is it beneficial to increase the intake tubing to 3 inches, from whatever stock is, 2.5 or so inches?? Or is it just the larger air filter that helps. That whole argument about the engine being a large air pump.....pumping more volume, and colder air is potentially a benefit, correct?? Now, is it worth $400 ???? Debatable I guess.....

lol
I just thought of something too. With rrutters thought process I bet if he is driving down the street, and quickly opens his doors, the pressure differential will make the car fly, since they will act like wings. Thats probably why lambo's stopped using them on some cars, just too dangerous to have a lambo flying

Classic... after Area gave you everything to answer his question.
ok kids,
time for 3rd grade science.
Children lets do an experiment. Yes, you too can follow along at home and do this. We are going to explain to all these "math and engineering" whiz-kids what CFM, PSI, and why porting doesnt exist.
materials needed:
balloon
needle
scissors
ok before you blow the balloon up.... poke a needle sized hole in to that balloon. Dont blow it up BEFORE poking it (i have to explain this since 11+ pages and people cant grasp it)
now. Blow that balloon up and watch it leak air ever so slowly.
the air from your lungs to the balloon is like the eaton supercharger (lungs) in to the intake manifold (balloon). The air that is leaking (needle pin hole) is the proper CFM going to the cylinder.
Notice how little CFM or air comes out. Notice the PSI created from blowing the balloon up (intake)
ooooooo
Now, lets free that intake up and cut a hole where the needle hole is about the size of quarter. Again, blow up the balloon.
Thus creating more CFM (out of the bigger hole) and less PSI (balloon size)
now...
if you can afford another balloon. Lets try what everyone else was talking about.....
Open your mouth as wide as you can and blow that balloon up. Whats this?
can it be?
yup im sure of it. The same amount of PSI and CFM is flowing through the balloon (intake)
Now children, i am done gracing this thread with my intelligence and ridiculing you all on what CFM vs PSI vs Dimensions really means.
special thanks to my after-lunch smoke to come up with this little project

I know it's sarcasm, but I'm on a roll here.
FAIL!
(PSI is a measurement of pressure)
Double the fail points for saying it twice!

I mean I am not here to take anyones side, but porting the inside of the housing will definately decrese HP. Now, if you polish the inside of the housing and P&P the snout youd see gains. Atmospheric pressure doesnt have anything to do with compressor efficiency. You gotta remember if the atmospheric pressure is some certain number, thats the pressure you are sucking into the blower AND out of the exhaust. If you are at sea level, its easier to suck air in and harder to push it out. In Denver it is harder to suck it in and easier to push it out. Really the argument here is which is the lesser of 2 evils? Neither. Its all about air density, atmospheric pressure once again has nothing to do with it. Yes you hear these guys up in the mountains going, "man I only see 12psi with GMS2, whats wrong?" If you think about it, for every revolution of the Eaton you are going to move one unit volume of air, no matter what the atmospheric pressure is. Now if you lived up in the mountains with a lower atmospheric pressure and could achieve the same air density as sea level, well then youd have an advantage at high altitude. If you could achieve a low psi at sea level where atmospheric pressure is higher then youd achieve the same effect.
Its the same thing as the myth of people moving to denver to train for the olympics or some ****. That doesnt do dick for you unless you have sea level air density going into and out of your lungs. This is why you always see those gatorade commericals with the athletes running on a treadmill with a hose in their mouth. Thats them being able to exhale into a lower pressure while breathing in from a higher one. Thats the only way athletes see benefit from training at high altitude. Same reason your car doesnt see any benefit from being at a particular altitude.

How it was stated u get points, but on a really cheap level. Grasping for straws lol majorly grasping.

Just my .02
This only applies to forced induction motors, motors that are NA, suffer from altitude density sickness. Forgot to mention that.

Even talks about the differences in altitude for NA and boosted applications.

holy ****............. barometric pressure is measured in the same units as my boost gauge
KPA....... they are the same measurements... and you can convert them to PSI or any other measurement of pressure. doesn't matter.
and there is nowhere on eather with barometric pressure of 0. thats ******* ridiculous.
the pressure is what keeps the earth together, if we didn't have that pressure, it would break apart or "explode". (not violently, but come apart is what i mean) or some **** like that my teacher told me lol

gravity creates pressure due to the density of fluids (including air).
The moon has no psi yet it doesnt fall apart as you state.
People would lose their fluids if we didnt have pressure, hence the cavaties we have. This is all off topic.

uhm no....

k someone who is a bit more open minded, and is correct
EXACTLY the apples and oranges comparison i was trying to avoid
some people are coming out of the wood work.
i havent even really tried yet. Wait til they throw in real numbers to crunch

Notice how that compressor efficiency map doesnt say dick about altitude.
