are there things such as black intercoolers. cos i wana build a sleeper and the black intercooler will hide nicely behind the mesh.

is it true that the bigger the intercooler the more boost you can run??

go read up on intercooler therory. Its all about efficency, bigger doesnt always equal better i can tell you that now. u must pick a cooler to quite ur goals.

u can paint any intercooler black, you just have to be careful as u can wreak th heat transfer properties and make it less efficent. Just read up on google for correct techniques

our XR6T has a painted factory black intercooler, and after doing 10,000KM all the black paint is peeling off. As you can see by the pic below.

Just use the mesh like you said, you wont be able to see much unless you have a closer look.

when painting just paint the outside and leave the fins unpainted...that wont affect the heat transfer properties noticably at all

Intercoolers have to be properly sized to the application

There are black coolers around, they are usually anodised or something similar. Whether or not they are sold in Australia I couldnt comment, i'm sure they would though.

As for a larger cooler making more boost? Not really. It all depends on the size of the core and how efficiently it can cool. Go read up about BaP (Bar and Plate) coolers versus TaF (Tube and Fin) coolers. That'll give you a better indication of how a cooler works etc :)

Because you probably cant be bothered researching, I figure I might as well tell you the basics of both coolers. What the advantages and disadvantages can be.

Ok basically you want a cooler that will cool the air quickly, and most coolers will generally do this well. But people designed different coolers for different applications, some to cool air to the coolest it can get, and some to cool the air to some extent then pass it on.

Most original manufacturers that sell their 'coolers with a car (Mitsubishi etc), will more than likely be using a TaF 'cooler because of the fact that it can flow air quite quickly. The only way you can get a TaF core to cool as well as a BaP core is by making the core larger (maybe this is what you were driving at). But if you compared both a BaP and a TaF cooler of the same size, then the BaP would be in front for cooling purposes, but the TaF for flow reasons.

Hope this has helped your decision :)

Only way you're gonna get your cooler black is by painting it... then mesh it with a silver mesh as a black mesh will allow you to see in more easily. (I know from experience :P )

In terms of bigger cooler and up'ing the boost, a bigger cooler may cool the air a bit more and therefore allowing a small increase in boost, but will also increase in lag....

A bigger (area) cooler doesn't necessarily mean you can cool more air, it's the thickness of the core that counts.

actually thats not correct, larger surface area is more important.

As air passes through the front of the intercooler it is heat by the transfer of heat from the intake gases flowing through the intercooler. So the air at the front of the intercooler will be cooler than the air exiting the back. Hence the intake charge being cooled by the back of the intercooler wont be cooled as efficiently, and so increasing surface area is more effective than increasing the thickness

just get a top mount :P

front mounts generally can cool better than top mount though right? due to obvious reason like the position and amount of air exposure?

They do cool better full stop. Which is why WRX owners that get serious about performance throw away the top mount and get a huge FMIC. :D

Its all about fluid flow.....as said read up a bit more :)

If you don't want to paint it black, another option is to hide it behind the front bar. Whether its black or hidden, if you look hard enough you WILL see it.

you gotta admit though ... if someone DID make a black-annodised style IC it would be soooo cool (I love sleepers) :P

Just spray it black yourself! It's not that hard and you save heaps of money (anodising an intercooler ain't going to be cheap). And you have yourself an instant sleeper. ;)

hey turbo_del_sol: from the pic i noticed the crx has a p plate on them, i was wondering how the hell do you guys get insuro on a modified turbo or do ya just drive with insuro?
Thats one sweet ride mate!.. sleepers are nice. :D but i think some fine black mesh infront of the cooler would be good to protect the cooler from rocks and stone chips which might over time wear away the black coat.

The cars still not on the road at the moment so I got no insurance. However Justcars will take on anyone for the right money... :?

I dont have the mugen kit on anymore just the stock bar now and yeah I got some black mesh to cover it. thanks .... ;)

I pay $1500 for full comp on a 95 Prelude Si with turbo, FMIC, exhaust etc. with Just Car Insurance. I am 23 with 60% no claim... It is the same amount if there was no turbo kit added. :roll:

can someone tell me if there is a specific type of spray paint to spray the cooler wether i need like high temp engine enamal one or not? my AVO kit came with a black cooler but its faded now and thinkin of spraying it black again..

radiator paint, or strip off the black paint and get it anodized black so it will keep its cooling efficiency.

Get an intercooler from an r32 gtr, they are big and black, but $$$ and hard to find sometimes

Anodizing is the only way to go without the paint stripping. Should be a few hundred to do a cooler

yeah there are anodised ones for sale in Aus... seem them advertised somewhere once upon a time.

I dare say though the high temp paint i bought off bunnings was pretty good, had it on some headers, never flaked... unlike traditional paint we're used to seeing, these kinda have a very fine dull powdery look... didn't even need primer or should i say i couldn't use it... and it's no where near as thick as a layer of normal paint either...

High temp paint means that it can withstand high temperatures, not that it has good heat transfer capabilities.
I agree with EGB18CT, get it anodised.

i'm sure a light coat will not effect the cooling to any noticable degree, but use HT paint as it is better quailty and does not flake of as easily

17-10-2007, 11:40 PM
ahaha amen.

I have a hunch aimre has a black intercooler which hasnt chipped, and logs of IATs show no reducing in efficency.

See the key here is HOW the paint is applied to the cooler. Spray at an angle over the core. The paint should only cover the bars/fins face. Thermal transfer at this layer simply is un-noticeable. Unless your core is .25" thick, u will not notice the difference. 90% of heat transfer is done wihtin the core/fines as air flows by.

Go pay 200 for your JDM (y0!) anodized blinging cooler. But amire is right. 2.95 will cut it. U will notice bugs before u notice chips.

my evo has a factory silver intercooler (not bling chrome) and mesh in front of it

heat transferring paint like radiator paint will be the best cheaper option

and why aren't there anodised IC's readily available... I'm sure there'd be a big market for it, and not just black but red, blue, custom colour lol etc etc

Becoz most people arent stooges like on this site and will just pay the extra $3 and spray paint there own.

Why pay an extra 50-100$ for anondizing?

Do u think anondizing wont effect its thermal properties????


Anodized coatings have a much lower thermal conductivity and coefficient of linear expansion than aluminum. As a result, they will crack if exposed to temperatures above 80°C, although they will not peel.

yeah that was my point.. it sticks differently than normal point and is a lot thinner therefore it won't reduce the thermal efficiency as much as paint. reason i mentioned painting headers with them is to back up the fact that they do not peel under extreme heat therefore would possibly be suitable for ICs as they cannot possibly get as hot or hotter... can they?

BUT then again i know nothing of both paints chemical composition and thermal effects to make that call... visually the idea is quite sound

Because he thinks spraypainting is cheap, and would rather it done the right way (right in his eyes) i think....

Anodising can be done yourself if you have access to the right chemcials and do not mind having a bath-tub for a few days. Check google, there is a few sites on how to anodise alloy.

I anodised the intercooler in my ute black and even got a red 'SS' in the middle with some experimentation. Surely, someone on this forum could do one up with a rec 'VTEC' across the front.
