Black intercoolers
Discussion
It was designed to have flow from the outset, it's just it wasn't the designers expert area and it wasn't quite right.
With relatively minor tweets the intercooler is effective in its current location so my personal view for the standard car he got it right, just didn't ' refine' it fully.

Andy, do you feel that your location for the intercooler is better than say dual coolers in or near the side pods like the racer did?

I also changed the intercooler box so heat from the turbo travels away form the intercooler... Simple but extremely effective change for me.
On my other car the inter coolers are going in the side pods, but the car is designed from the offset for them to go there, plus it's twin turbo and is logitudal mounted engine.
Packaging and length of pipe work is as big a factor as intercooler efficiency...

Lookalike with a little work you could even run the middle mounted intercooler for supercooling! Lol

Well I'd say having them in the wheel arch wouldn't be a bad idea, I mean the ideal is to have less airflow through the wheel well to reduce drag and lift rather than to encourage more... Conflicting interests IMO.
Plus the turbos are not on either side of the car but front rear thus I think the single intercooler would still be better.
Saying that I've seen proper telemetry from twin turbo 600+ car on track with the pro alloy in stock place and it didn't have an issue with inlet air temps, so why change when refinement is all that's needed?

surely the airflow is by far the most important part of the intercooler, look up something like Newtons law of cooling.
it is obvious that when the intercooler is acting as a heatsink (no airflow) it will work a bit better, but only until it soaks out
If you want it to work better increase the surface area.

But is it just about getting air to the intercooler or what actually happens to the air? For example ww2 air cooled fighters found it was beneficial to slow the air down as it went over the cylinder heads as they extracted more heat from the cylinders for less drag than with large opening and lots of airflow.it is obvious that when the intercooler is acting as a heatsink (no airflow) it will work a bit better, but only until it soaks out

Also look at f1 radiators and intercoolers that are thin but massively lent over. I'm sure max mentioned on hear somewhere that you only need an open 40% the size of a radiator to provide sufficient airflow. If that's the case is airflow the real limiting factor in the noble or is it the intercooler?
From andy's comments above it looks like the noble is more intercooler restricted than airflow!
Not saying improving both won't help though!

My guess is that if it gets to big the pressure drop when the air cooled would be intolerable Also look at f1 radiators and intercoolers that are thin but massively lent over.

My intercooler is a lot larger than the pro alloy one, plus I believe I have a lot more air flowing through due to the body mods I've done (the fastback and the rear grill area)... But I genuinely don't think the stock body with the pro alloy intercooler needs a redesign as it's proven tweets get it under control IMO.
The biggest mistake people make is forgetting to open the intercooler exit area.... It's why I recessed the number plate so I could permanently relocate it legally lol... I also don't run a grill at all at the rear.

Answer from Mclaren
An interesting question, and fairly straight forward to answer: the choice of surface coating/colour depends on the installation. If there are other surrounding hot bodies that will radiate significant heat to the intercooler, then you want a highly reflective surface to minimise heating from infra-red radiation. If no other surrounding hot bodies, then you want a coating/colour that has a high emissivity when at a temp of around 100degs to maximise radiation heat loss from the cooler. Most non-reflective paints, of any colour, have such a property and of a similar value at this temp, so black, or white, (or green!) will do in this case. Hope that helps
