whats best for the air temps

matt black or silver, one i took out was matt black and new one silver, going to mod the ends so inlet/outlet points towards the engine and pssible paint it matt black if it's better the act

cheers Neil

 

up

someone must know

silver or matt black for an intercooler

which is the best?

 

black

 

Matt black mate.

 

MATT BLACK

 

right settled them

matt black it is cheers

 

guys thats crap


the i/c paint is not the normal matt black paint

so stay silver imo

 

the intercooler i took out is matt black and scrapped the paint off 1 bit and it's alloy underneath

why is it not normal matt black paint

 

i thought black holds the heat

 

its a special paint that reflects heat

 

exactly what i thought, absorbs it also, hence why you feel hotter in a black t-shirt in summer

 

BULLL SHITTT

It's radiation anyway, so makes shat all diff.

 

sorry just relaying info stu gave me about 6 months ago

 

special my arse! specific, maybe...

 

Rick
im with you mate

 

explaint the difference then

i never ment special as in its fabled paint,,,,,,,,, just that its not NORMAL matt paint they use adn nobody knows where to get it when i last asked

 

should i paint the radiators in my house black tomorrow?

 

Not unless ur a goth!

 

radiators should be called convectors though

 

 

conducts mate

 

SO WHATS BEST ?

 

My science teacher said the best colour to paint all the radiators in your house would be black, but people pick white obviously cos it looks better

BUT, I always thought black aborbs heat where as white reflects heat But which colour would allow the most heat to be taken away by the air passing is anyones guess i'd probably say plain alloy so the paint or whatever doesn't act like a heat jacket

I'd preper black though cos it would look better, and aren't the RS500 coolers black? it's too hard

 

theres a difference,

a Intercooler wants to absorb cold, from passing by air,

a House rad wants to release heat to passing air.

 

it makes fook all differance as the heat inside your intercooler will always be hotter than ambiant, and its also force-cooled , if you wanted to 'warm up your cooler then you owuld paint it black as black absorbs heat (aslong as the ambiant is hotter than the cooler ) if you wanted to remain a cool internal temp from higher ambiants then you would have a silver or bright colour to reflect the ambiant (being higher than the internal temp) which all of the above never is or we wouldnt be running intercoolers !

- i thank you

 

so why are standard coolers and rads black the ?????

 

because thats what colour behr made the originals - have a general look say take 100 cars of varying makes and models - you will find its a 50/50 mix of black/silver finishes

e.g manufacturers use subcontractors to make there parts so whats availabe gets used ! - bu also do you think the likes of radtec/pace/pro-alloy would all be in business if all the parts had to be black ? and they had been producing silver finished products - it makes fook all differance

 

if black conducts heat would it not be better for the intercooler to be black as moving at speed thro the air would cool the forced air quicker ?

 

do you honoustly think that the colour of your intercooler is really going to matter at windspeeds of 100mph+ - it really wont matter

 

heat exchangers on production cars are painted as the car manufacturer wants them to last more than 5 mins after the roads have been salted

whether they are painted silver or black is largely down to manufacturer preference, i.e a silver one is easily visible through the front grille, but a black one is hidden.

if anyone (e.g. proalloy or whoever, or a magazine) wants to do a proper scientific test, the test facility that i work on could be used. 250 bhp rolling road in a temperature and humidity controlled test cell with full vehicle frontal area windspeed up to 70mph.
