just as a thought if you were after or better still want to lose a bit of heat and inherently gain a bit of power :thumbup: which i guess is why you got one in the first place so how about looking at 2 more options :

1- paint it matt black
or
2-paint it with aluminium oxide paint (the stuff with bits in) if you prefer the silver

before you flame me i will explain:

a front mounted (or any for that matter) inter/charge cooler is in basic terms a cooling radiator designed to input heat (via gas/fluid) and discharge it through its shell to remove the heat of the source input - basically take warm air in and get rid of the heat

option 1 - black is a better conductor of heat so therefore will draw more of the heat from the air inside the cooler (not a lot but more for sure) and will match the wheels bill :roflmao: (when you next see an air cooled motor cycle take a look what colour the engine is ;) )

option 2 - if you want it to bling :redface: instead of painting it black use aluminium oxide as it is still silver but is spray coating of loads of minute particules of aluminium that basically when coated over will increase the surface area of the cooler by a good 200% - ask anyone with regards to oil/air coolers if a greater surface area is a good thing :thumbup:

just dont go too mad and start blocking holes off :thumbd:

ye i know - it wont raise ya boost by 50% or give you zillions more BHP but think about it - over all the little things you do they all add up to the sum of the parts and as heatsoak is well known as an issue it can only do good eh :thumbup:

all in the same principle my old man taught me for autograss - take a car - say 1200lb in weight - of which 400lb is unrequired weight (non stress/brackets/panels etc) if you drill correct holes in each piece you could halve the weight of each bit therefore removing close to 200lb out of a car - how much faster do you think YOUR car would go without the equivalent of YOU in it ?? [B)] all the little bits DO add up :idea: :cheers:

Well just ignore the (poor) thermal conductivity of a hydocarbon based paint then!! :roflmao:

anodised?

purple anodised mmmm 1990's chic

instead of painting it black

[/I]

ER?? he did!

lol!

Anodised black alluminium coolers are used by OEM's for corrosion resistance not heat transfer!

Ok it might make a small difference, but as an intercooler is basically a convection / conduction device not a radiation device (due to the low delta T between operating fluids) it ain't gonna be worth much.

However if it looks cool, then go for it! :roflmao:

So painting or anodising the INSIDE would be a good idea...... :blink: ;)

why are motorbike engines painted black or is it anodised then ?

always seem to be

black - air cooled

silver - water cooled

but then most late ones seem to be water cooled and black now - aggggh :whistle:


i do like the idea of purple anodising though - very chic :roflmao:

i was always gona paint mine black so it was more oem , never got round to it oh well

I have gone for the non shiney finish.. anti bling, so large as it is, its not "in ya face" maxP stylee..

Heatsinks come in black anodised finish.. slightly better heat dissipation apparently... :)
