The race aluminium polo rad I'm running seems to just be only coping with the m3 lump feeding it. At higher speeds its fine, but at low speeds the cooling fan is doing most of the work. I'm going to try and duct above the nose cone to force air through the rad rather than over the top.

If this fails what radiators are others using? The polo rad was the only one I could find that would fit!
