I was thinkin about runnin the car with no hood like the hot rodders did back n the day....Im sure the hot IC temps will be null n void all together.....I bet it looks tough.

 

If you can see the airflow, but you still think that the air is intended to go over it, not through it, it is time to get glasses. :smile: Think about your radiator, it is exactly the same as your IC. Would you block the back of the radiator? How about placing your radiator flat? Why would the IC be so intricate to have so many ways for air to flow through it? If air just has to go over the IC, it would be best served by having a flat surface on top, that would provide maximum surface area to exchange the heat. Even better, it would have ribs/fins on top to act as a real heatsink. The heatsink part of the IC is that area that allows air to go through it, not over it. That oversized IC in the picture, better have a way to stop air to the right of it, since our Scoop opening is bigger than the IC. If it does not, the air is escaping to the right and VERY little would go through the IC at all. That IC would act as a deflector for the air to go to the hole in the right, the point of least resistance. I am sure we can all see this.

And i see dead people!

 

That was a great reply, I am getting back on my chair after rolling on the floor.

 

 

Looking from the side, over a model (as the poster was referring to a modelling situation where gas of another density [methane!] is pumped over an exposed surface!), you can see airflow in many cases. Look around for vids in windtunnels. If pressure gets high enough, and velocity fast enough, you can absolutely see the direction of flow, because particles are increasingly clumped together [whether in regions of laminar OR turbulent flow] in the center of the airflow. The particles make the air no longer clear, and increase the viscosity of the air, which increases the likelihood of ordered flow. This reinforces the definition in the area with the particles, because they become increasingly clumped together.

This can all be understood if you study Reynold's number. RN is used to decide whether flow through a conduit will be laminar or not. The number decreases with increasing viscosity. When Reynold's number decreases, the probability of laminar flow increases. This is proven theory. This is physics.

Now, I did not say that IC's should not flow air through for cooling's sake. I said that the large mass of air entering at speed through the stock scoop and diverter does not flow through the IC EN MASS in OUR CARS because of the resistance to flow down below. I guarantee that not all of the cooling comes from the air flowing through. Some, yes, but not all. I just have a different theory than some of you about which aspect is greater. I believe mine because I KNOW that the larger ALTA diverter improves power and cooling from firsthand experience. That much is popularly KNOWN.

Our radiators have plenty of extra space behind them where air can pass through, span the fans, and proceed out and under the car. There is far less resistance behind the radiator than below the IC. I am 100% sure of that. I am merely arguing that there is too much resistance down below the IC to efficiently pass air. Some (or maybe most!) of the air entering our scoops will pass around the IC and not through it.

Someone, just do an experiment and see if a) the cooling goes down significantly with airflow through not allowed and b) if NO cooling happens post-IC when this happens. I know that cooling will occur with the bottom taped. And, I theorize, it may cool much better that way than you all feel it will.

It should be said, a properly placed IC, whether top mount or front mount, will use the vanes efficiently for cooling. The STI has a 'top mount' BUT it isn't over the head, and air flows efficiently through the vanes, exiting behind the block.

 

Seriously, you are the one with the highly dubious theory. It is your responsibility to test that theory since it contradicts reasoning and science. Also, do you think the Subaru WRX uses the "around but not through, visible air lines, dry evaporation" method as well?

 

Our IC isnt over the head either.

 

WTH? Where would you say the head is then? It's under the fuel rail and some wires, which are under the IC.

 

.

 

As far as i seen when taken these cars apart is its more over the SC than the head is wa si meant.

 

So that's what a head looks like.
I thought it was the thingy with the cover that had the spark dealies in it

 

Funny. . You guys really wanna bust my *****, huh? Well, I've said it before, it's a theory and I believe it. I'm a decent person. If I'm wrong, I'll concede. But not until then. In the pic, and I'm sure most will recognize, is the intake manifold in front, the head is under the IM and in back of it. Now, the diverter [above the IC] is over the fuel rail which is over the anterior 1/2 of the head. Or am I seeing things?

PS: The CENTER of the head has plug towers. The anterior portion is where the fuel injectors are heading. The injectors sit in the fuel rail ports.

 

This is too funny, classic!

For those who must pass a kidney stone, have a laptop, wireless set-up, and lock yourself in the bathroom with plenty of drinking water, meds, and find a thread like this!

 

Good luck Tony! Don't forget to have backup supplies of all of the above. It's a PAIN, i know. My thoughts as a future physician are with you.... Heh, almost sounds wrong, but it's my job...

 

The IC airflow visualization issue can be solved with a plexiglass hood, colored dyes and or yarn, and a video camera.

 

The MCS has its fuel injectors located in the intake manifold runners. The fuel rail is on top of these. The cylinder head is located rearward on the car. The cylinder head is the black thing, not the silver/gray/white/green shiny things:

 

You didnt pass that thing yet?

 

Ok chief....you go do that and let me know how it turns out for ya.

 

I'm amazed

- that I read this whole thread
- that some of you actually believe ingsoc's "theories"
- that Andy is spending so much time argueing with him

The only thing you've said that was remotely correct is that the flow path isn't ideal.

 

THESE ARE THE DAYS OF OUR LIVES!

 

Why don't you have ingsoc operate to remove the stone? He can insert the scalpel over and around the kidney, but not through ... and the stone can be removed via evaporation! :impatient

 

LMAO.......i think a drop of pee came out!

 

ingsoc, dude, give it a rest. These guys are going to bury you and your theory ! You cant come to a bazooka fight with a bb gun and expect to win. When you stated the IC was over the head you lost...clearly.

With all that said I can honestly say alot of the info went over my head and I dont clain to understand physics etc but you are definitly fighting a battle you CANNOT win unless by some freak of nature you go out and do the tests yourself and prove your theory.

Make sure when you hook up your equipment you connect it to the right parts since its clear you dont have a full understanding of how the mini engine is layed out.

 

Too much f'n information
