Ok What will it be Black or Silver

[Paulm]

Trying to work out which is best in terms of heat control.

My S2 intercooler is silver, my new RS2 intercooler is black.

The metal inlet pipe which runs along the side of the engine close to the turbo is black. but the inlet manifold is silver

My thinking is Black absorbs heat and silver reflects it. so, Intercooler should work best in black, the inlet pipe should work best in sliver

any1 agree or disagree

Bit of a strange concept this but balck is the best colour for absorbing heat but also the best colour for radiating heat.

If you have a black intercooler then it may absorb a little more heat that a silver one but it should radiate the heat from the warm air passing through it better than a silver one.

Overall I think black is the more efficient colour for an intercooler - probably a pretty close thing though.

Yup your right, the best colour to have the intercooler is matt black since it has a greater surface area compared to gloss.

Anyone remember that guy from the Fast Show on BBC a while back - the painter ?

Black, Black, Blaaaaaack

Seriously though - yes - BLACK is best radiator (and absorber) if my vague memory of O-level physics is correct.

You might want to consider the plastic pressure pipe of later S2 engines (roughly MY95 onwards) as this does not get anything like as hot to touch as the original black metal item.

Ok Black it is then.

Will have a look out for a plastic pipe also.
