CLown with as many sections and ridges drier duct has, how does that not create turbulence?

Simple question. Simple answer, if one has a clue.

You answer told us who, and what, you are.

yea keep reading through and then i finish the rest of the reply.....
i still havent seen anything yet that you produced in this thread to be at all helpful.

What were the conclusions?

For those who know aerodynamics---------a smooth tube has no resistance to air going through it-we can all agree on that

a tube with ridges, and other obstructions will cause turbulence or in other words, causing friction and reistance to airflow.

Then lets throw in a electronic sensor that determines the air flow. or mass air flow sensor

Laminar air flow- or "smooth" airflow flows more efficently because the incoming air charge has little to no turbulence will flow through the honeycomb screen (designed from the factory to straighten air flow in front of the MAF for more accurate airflow readings) (fact) faster then a turbulent air flow will. My whole case in point is improving air flow for more power and better engine breathing and effiency. Now matter what level of performance you are at it is key to improve engine breathing for optimal performance stock or highly modified.

In your above post you mentioned what percentage of people who have nothing or something to gain from CAI's.


I was talking about it in reference to the topic we have been discussing in this thread. Its what people do on message boards. If it were a different subject, or a different context, a new thread would have been made by me. If you need to be reminded of things that have been dicussed, all the pages are there.

Quote:
And advanced enough equipment? come on andrew fuel injected/Maf equppied cars are not simple by any means.


Who said they were? (They are not overly complicated either) However, complex does not mean a performance level in proportion to the level of complexity. I already discussed the definition of "advanced" that I was using. Advanced, in the terms I have been speaking, is using components that are a step above OE stuff, devices that are capable of being more precise than the OE. Nothing you have on your car is "advanced" according to your signature, except the "P&P" work.

Quote:
So as for the advanced statment well yea all of us except Norm have advanced equipment from the factory.


Not true. Advanced would be something that is more precise than the "factory" produces.

Quote:
So let me re-phrase my idea then. Since we all run "advanced" equpiment, it is beneficial to make everything run efficently as possible.


Only if the ends justify the means. For example, one would not invest thousands in a set of heads, and not do anything with the rest of the engine.

Quote:
By way of certain modifactions. We all know that drier duct has a crap load of "ridges" when air enters that turbulence will follow when it hits the MAF "screen" it has to be straightened out to enter the TB.


Lets see the data. Until then, you are shooting out in the dark from your azz. Corrupt data processing leads to corrupt results. GIGO.

Quote:
how efficent is that???


Efficient enough for the components used. You only have to make the intake efficient enough for these components to work properly.

Quote:
now lets think my current setup has one long radius bend of PVC, The air flows smoothly enough to get Laminar before it reaches the MAF, since the air is already "straight" it passes through the screen with little to no resistance.


Good for you. If/when you get to the point that it will make a difference for your engine, you will be a step ahead of the game.

If your aerodynamic knowledge is as in depth as your thermodynamic knowledge, you have no business lumping yourself in the group that "knows".

Without quantitative data, that is a pointless statement, in regard to the flex-duct you are referring to.

How many times must we all repeat ourselves? At some point, the efficiency of the intake will exceed the efficiency of the engine, and any further modifications to the intake are moot. The arguement has been, that there is an improvement in using a smooth-walled pipe in place of flex-duct in a nearly stock application.


Quote:

And again, there comes a point where more efficient air flow is not going to improve any part of the performance or operation of the engine, because the 'bottle neck' is now somewhere else.

All you can do is improve it to the full potential of the components you are using.

Not if you know aerodynamics

a 3'intake or cold air intake alone will not exceed the efficiency of the 3800 series engines by itself, or let me ask this do you "factual" data?

oh really so youre saying in effect is that cold air intakes dont do anything power wise? :^o

which would mean a increase in performance then right. Oh but in the post above you state making the air flow mre efficent dosent do anything to improve performance....sooo which one is it?

I'm certain there is a direct correlation between your previous "show" of knowledge in thermodynamics and now, with a more complicated science.


Quote:

We have no data to tell us how much less flex duct flows. Sure a pipe that has a smaller cross-sectional area, or is ribbed will flow less than one that is larger, or smoother. We went over this pages ago. What's your point?

I don't think I "factual" anything. I don't even know what the hell that is supposed to mean.

Quote:

Read whats there, not what isn't. There are benefits to be gained, but there is a limit to said benefits when using a near stock setup.

Don't be obtuse. I clearly said there are benefits to it.

Lol you know what...is there anything else to discuss that has a positive contribution to this thread? i think we went over EVERYTHING. and will really help people to decide what they want to do. Andrew IMO since youre a moderator i think you should lock this thread because there really nothing else but suttle insults to throw around.

Yes there is.

We can begin with the following:

You made the statement. You have not explained it.
