I need to get planning on my radiator, was doing some searching and came across this on eBay.

One summer track day I started to get oevrflowing radiator, and decided to add lightness with a aluminium one, but it turned out it was a head gasket that was starting leaking. I also added electrical blow through fans to the new radiator (more efficient than the stock one), as I have sealed up the bay with the foam and since under bonnet heat can rise quite a bit when stoping after a run.
Copper conducts heat better than aluminium (provided a good coolant is used and it is not gummed with green oxide or scale), but I think aluminium radiates better, so if one if after the best of both world copper tubes with aluminium cooling fins could be used...
