i think the kist thyat dont fit properly are available off trade me. they dont have the nipples for the two vaccuum hoses to attatch to before the throttle body. (probably other things too) i believe it was the kit that included full piping that doesnt fit
That's right, and the cooler would be of better quality.
Or if you didn't want to go with an Evo cooler, you could use a stock-sized China copy of an Evo cooler. Available off ebay for around $150.
The piping may be cheaper than that too - I'm thinking worst case scenario with the $400-500 range.
Yeah mate no worries. I'll be looking at doing it when I get back from O/S, and I figured if I was getting piping made for my car I could see about getting some sets done for other members at the same time. I wouldn't be making any cash out of it - just helping out.
Thats cool; I think we all appreciate any effort other members put into things like this. (i.e. the strut bars).
I would be happy to sling a few $$ extra for the effort and time.
Also: if you could find out about black powdercoating; perhaps it could be a package deal. Black pipes would look the stuff in the engine bay. Keeps that factory look but still reeps the rewards of being metal over rubber/silicone.
Let us know when you follow through with the idea.

Oh yes, I love it. I cannot wait till I get my cooler. How did you spray it? Just normal spray or powder-coat?

Doesn't painting an intercooler impact the heat transfer ability?
a few light coats of paint wont hav a major effect, perhaps a degree or two at most (like worst case scenario) but if u were to lay primer, paint and atop coat of pant then yes, t would effect the cooling efficiency of the cooler.
think of it like this, u hav a meat pie, its wrapped in that crappy plastic, u can still feel the heat from the pie. if u were to wrap it in a a few serveittes then the heat is trapped and u cant feel it.
if u were really concered (and i might do this myself) cut some stripe of newspaper out to mask off the fins on the cooler and only spray the tubes and end tanks, that way the the actual parts that do the heat exchanging hav no paint covering on them
[also, black paint absorbs heat about the same as other colours, but it also disapates heat the fastest of all colours.]
thank 3 semesters of thermodynamics for that lol
hope this helps

mmmmmm Pie aaarrrrrrggggghhh
The paint thing as you say can't have a detremental effect on the coolers effeciency as if it did, companies like Nissan would not have painted their GT-R's cooler black.
Remember that there are going to be other issues.
Black will defiantly absorb more heat than the lustrous metallic surface and could be an issue in summer. however i do not think that radiation will have a major contribution to the overall heat transfer (except if it gets direct sunlight)
There will be contact resistance to the heat transfer (usually small but still an issue) between the paint and the metallic surface.
However the most important area (the surface area in the core) is not usually painted. If this was painted I would think that there could be a more pronounced impact on the performance of the intercooler.
is the GTR cooler painted or a surface treatment?

Like does guy who the pie was taken from wanting it back... lol:lol:
Does black absorb more heat/radiation or does black absorb more light thereby holding more heat/radiation? I thought it was the latter but please enlighten me?
Now there's an Advert... "Do you paint your Impotent areas?"
Sorry, couldn't resist.
heat and light are inter conected. the higher the temperature the shorter the wave length (or higher the frequency) emmited. rememebr 'light' is only a very small section of the electro magnetic spectrum.
using the stefan Boltzmann law we deive the following formula.
q = ε σ (Th4 - Tc4) Ac (3)
where
q = heat transfer per unit time (W)
ε = emissivity of the object (one for a black body)
σ = 5.6703 10-8 (W/m2K4) - The Stefan-Boltzmann Constant
Th = hot body absolute temperature (K)
Tc = cold surroundings absolute temperature (K)
Ac = area of the object (m2)
it is the diferance in tempeerature that make me think that keeping the cooler out of sunlight would be a good idea. in reality a shinny surface will reflect alot of this heat.where
q = heat transfer per unit time (W)
ε = emissivity of the object (one for a black body)
σ = 5.6703 10-8 (W/m2K4) - The Stefan-Boltzmann Constant
Th = hot body absolute temperature (K)
Tc = cold surroundings absolute temperature (K)
Ac = area of the object (m2)
of couse then comes the question 'why then does metal get so hot when its int he sun?' this is due to its high thermal conductivity.
a bit of a ramble but i hope that helps.

to put it simply, yes it does.. speaking from my stupid experience..
i lost approximately 50-80kms out of my tank when i had my cooler painted black.. was matt black and it was a typical paint (none of those heat resistant paint)only had 2 coats on it too..
But I believe Gary have replied with something more complex

If you paint it really thickly then you will lose some heat transfer ability. Anodizing it black however should be ok.

Pure and simple - I didn't want it to stand out as I like the factory style look.
From my point of view I figured that as you only paint the very front part of the cooler (i.e. you don't paint down inside the fins, nor the back) it should only have a marginal effect on cooling, and either way it still should be better than factory...

Our stock one is painted black, so does that mean if we strip the paint off it we'll see some major improvements?
Guess what rocked on up at my place today ... mmm evo 7 cooler. Needs a good clean, but no traces of oil in the core inlet or outlet; nor is there any damage front or rear. (well except for a couple of bent fins on the front)
Also came with the pipes; so should be able to work something out to work in with the standard setup.
IMO not bad for $150...

painted black is more efficient auto speed did tests and it was easily proven, use a spray can not thick paint
silver or chrome looks better but not as efficient black is always the best for getting rid of heat
