I used a wire brush on mine to get the worst off then sprayed silver over the top until you couldnt see the Forge writing.

Try not to paint your intercooler as it insulates it and defeated the point of having one.

If you need to paint it, try radiator paint. Its more conducting (apparently) so will allow the intercooler to work better :thumb:

how did you fix your oil cooler to the front of the car ?

any pics?

Sorry my pics are so massive, I don't know how to make them smaller.



There is a long bolt going through one end of the cooler with a long spacer in between the top and bottom of it to stop them being pulled together by the bolt.



The left hand side is pretty close to the radiator so I cable tied some old rubber car mat in between to stop them rubbing.

I remember it from physics at school.Fond this if you want some geek-speak :p

" Aluminum heatsinks of various shapes and sizes are widely available for cooling components.

- Often anodized with balck oxide coating to reduce thermal resistence up to 25%
....
....
Stefan-Boltzman law describes radiative heat transfer:

Prad = 5.7 * 10^-8 * E * A * [(Ts)^4 - (Ta)^4] in watts
where:

E = emissivity
black anodized aluminum E = 0.9
polished aluminum E = 0.05

A = surface area (m2) through which heat radiation emerges

Ts = surface temperature (K) of component
Ta = ambient temperature (K)"

Matt is better than shiny as the "shinyness" itself helps reflect heat.Apparently when there is forced airflow it doesn't make much difference but seeing as there are many times when you are stood still or in slow-moving traffic the black should perform better.

Indeed it does, however the overall effect would be nominal and like you said once moving its not really viable.

It depends on what you do with your car and whether its sat around in traffic, waiting to hurtle down the strip or if its used at speed say on a race track?

He is an interesting one, why not spray your oil cooler and alloy rad matt black also?

If you know somebody who is sandblasting, go to them and ask if they have an abrasive called ''Olivine'' or a really small gritt standard abrasive.
I've used it to blast my intercooler........4-5 bar of pressure and olivine.

Yes I have considered spraying the oil cooler and radiator too, but I have nearly run out of paint :p. I want to see how they get on temp wise 1st though as I think they should be up to the job really already.The car is quite hard core for a road one and sort of in between for a track car so its a bit of an all-rounder.
Plus the main reason I sprayed the i/c was to stop it being so in your face, any other effects were a bonus really.
