I like my small precision IC.. Kinda small. But all that is needed for a mild setup.. Plus i can keep all my bumper support on my EF

thanks for proving a good point

Bah! I bought mine because it was only $155 shipped. It's worked fine for my setup. Stock Z6 w/ a TD04 14g turbo. Only running 7psi and making well under 200hp.

In the late summer/early fall (when I first installed the turbo) I would feel the turbo and intake sides of the endtanks and the intake side was always cool.

I have heard that JRC intercoolers don't flow as well and arn't as efficient as others, but I have no complaints and it's worked fine for my moderate setup.

The Garrett and PWR cores are well made pieces. We have used both on projects (air/air), and IATs were always 10-15 deg above ambient...so they work very well When you decide on a FMIC, you have to keep a lot of variables in mind, not just how much power it will support and how it looks...

i just bought this intercooler. after much research it seems the best for the money.

i can't wait for it to arrive.

i did a couple couple pulls well alot of pulls plus freeway pull from 40-140mph...hehehe with the laser temp gun that i had i originally clocked in the hold side of the fmic at 50deg F and the Cold the side to be the same i dunno if this laser temp gun is off in calbrations or anything but after all those runs hot side increased to 95deg F and the cold side still remains at about 51-52deg F and then i touched it with my hand still cool

i think maybe the weather had something to do with it its like freezing outside and hella windy

my 8in JRC still holding up at my boost level

even at this after reading this post i want to upgrade my fmic to like a spearco or precision or something....

Weather plays a huge role in the effectiveness of your entire cooling system. The way heat propogates is from hot to cold. Heat wants everything to be hot, so it spreads to the coldest to heat them up. However since you can't get "something from nothing", when the heat moves to the colder object it takes some from the hotter object.

When you put ice in a glass of soda, the ice doesn't make the soda colder. The soda tries to make the ice hotter and in the process looses its own heat. The greater the seperation in temperature the quicker the heat jumps to the colder object. The hotter object will loose heat until the two objects are equal in temperature. So in the instance of ice in a glass of soda. The soda heats the ice and becomes cold in the processes. Once the soda and "ice" are equal in temperature the liquid then gets hit on by the air around it. Since there is usually more volume of air in a room then the soda in the glass, the soda will go to "room temp" after a while (and technically the room will have cooled down slightly).

So consider your intercooler. The hot air inside moves over the surface of the intercooler which is colder, and so the hot air gives up some heat to the metal. The metal is then exposed to the outside air which is colder thus the intercooler looses heat to outside air. And its a repetitive cycle. So the difference of the air temperature inside the inertcooler and air outside the intercooler make a difference. I have a temperature probe thats right before my throttle body, so I see air temperature after the turbo and intercooler. When its really cold outside like 40* I see intake temps about 10*-15* above that. When its hotter outside like 90*-100* I see temps sometime 20*-30* above that. Thats because it takes longer to transfer the heat when the temperatures are closer to each other.

Now why are intercoolers more effective while driving on the highway then sitting in traffic even though the air temperature is the same? Because when the intercooler is sitting there giving off heat the heat is actually transferred to individual molecules of air that are touching the intercooler. Once those molecules heat up they can either pass some heat off to other neighboring molecules, or they can get out of the way and let fresh cooler air molecules take its place. So when there is no air movement it kind of creates a thin "shield". But when your moving through air the molecules get some heat transferred to them, but are then moved out of the way quickly.

This is why wind makes you feel "colder" even though there is no difference in temperature....your skin is simply becoming a more efficient heatsink.

The wors "intercooler" and "too big" should not be used in teh same sentance.

You damn Honda boys are starting to sound like domestic guys with this "Bigger is better" stuff.

If the intercooler is too big you'll have a pressure drop, or an increase in lag because the intercooler is meant to be moving more air through it.

That's like getting an SC61 to push you to 300. Yeah, it'll get you to 300, but the lag is going to be shitty as opposed to using a T3/T4 50 trim that is good to about +/-300HP.

The best thing to do is get everything matched to what your goals are.
-Get the turbo that is going to take you to your goals with maybe a small cushion for conservative tuning.
-Get an intercooler matched to your HP/flow requirements
-Charge piping sized to match your flow requirements

I think if more people had power goal set in stone and got the pieces to take them to that level more people would be satisfied with what they have.

That's like my next setup. I want to use a T3/T4 50 trim to get me to 300HP. People keep asking me "Why don't you want to go with a 60 trim so you can go bigger in the future?" My reply is "Because I want to go to 300HP for now. If I want to go bigger I'll adjust my setup to take me there."

edit: Westrock2000, that's a good explanation. Is that physics or chemistry? The reason I ask is because that's something we covered in my chemistry class my senior year.

I would say Chemistry, I covered it in Seminconducter classes though. Same with how vacuums work....so many things in our daily life are really so abstract from how we think they work.

That's because the "How & Why" isn't important, it's just the fact that "this & that."

Like taking a ****. I take a **** (this) & I feel better (that).
Or your example:
I put ice in my hot soda (this) & the soda gets cold (that)

My simple/laymen's explanation.

I used to love science and math until I got to chemistry. Math+Science=Chemistry= BORING!

HT-physics, maybe. Where did you learn ANY of this?

In real life, your skin feels colder than than the actual temps because it IS getting colder. The water evaporating off of your skin takes heat away from your skin, since water, like any liquid, needs heat to evaporate. The air has less water than your skin, so if dry wind blows and evaporates the water from your skin, the water evaporates and steals heat from your skin. Net result, your skin is cooler than the air temp. Haha, imgine if everybody dies in temperatures over 100 degrees?

I don't want this to get off-topic, so I'll throw a car example in there:
Methanol or water injection works - because when you inject it in, it evaporates because of the heats in your combustion chamber. The now evaporating water or methanol takes heat away from your air/fuel (and combustion) charge when it evaporates - now you have a cooler charge, and hopefully less detonation. Same with running richer - more fuel to evaporate, so your charge is cooler.

I'd love to pick apart the rest, but most of you will only think I'm being mean. I'll give you a C, since at least half of it was true...

You just repeated what he said. Things cool off because they lose heat. It goes from high energy to low energy.

Your car example: combustion chamber is high heat/high energy, water is low heat/low energy. The water absorbs the heat/energy of the combustion chamber which has a net result of a cooler combustion chamber.

When you sweat your body is taking energy/heat from your body and passing it to your sweat. As air passes across your skin it absorbs the heat from your body, in turn cooling you off.

edit: I support what he is saying because I learned it in highschool biology and chemistry. If I remember I'll look in my girlfriend's chem book to support what we're saying.

The sweat is water, your skin is constantly renewed with water which is on the surface of your skin. Because water has a significant vapor pressure at 98 degrees (please don't make me explain vapor pressure, you were probably asleep in chemistry too), it evaporates off your skin. The evaporating water (sweat) takes the heat <U>from your skin</U>. Even if the air is hotter than your skin, it will remove the evaporating water, even if the air is hotter than your 98 degree body. That is the only mechanism your body has to stay cool (well, I guess your humidified breath does the same thing).

You explained ANOTHER process that goes on at the same time. The body transfers heat to the water which is then moved away taking the heat with it. The only reason you &lt;visibly&gt; sweat is because your body is not doing as good at getting rid of the heat as it would like and has a secondary form of dissapating heat. Just like an intercooler can work by itself or you can spray water on it to help. And yes many poeple die simply because the air temperature was too hot.

I know that the human body constantly gives off moisture...I work in a fab that is always 60* yet I constantly "sweat" in my vinyl gloves and shoe booties simply because the moisture can't leave. However it was not important in what I was trying to say to the guy who had a hunch. He didn't ask me why ice cubes get smaller in a freezer even though its freezing. And I didn't reply in an effort to make myself look smarter than him...I wanted him (and others) to know that he was on to something.

What I meant was that the air feels colder even though it really isn't. Not that your skin temperature does not change. However it still makes your skin dissapate heat better, which would imply that you cool off, which is what you said.

Also thats a good idea, use a half width radiatior to make the plumbing easier.

I have never heard of poeple having problems by going from stock full width to a Civic type performance half width.

Not to add to the fire, but maybe the yellowitr (DC2xxxx) had an old version of JRC? I remember when i was thinking of buying one around late 2003-early 2004 right b4 i bought he changed them and his prices went up. Not saying it justifys anyones proofs but just a suggestion.

I know why ice cubes get smaller in the freezer. It's because the water is still evaporating.
