Aluminium radiators

[Barrie Robinson <barrie@look.ca>]

While reeling in ecstasy because my MGB GT V8 just flew down to the BIG car 
show I still have this nagging ":the engine bay could be cooler when going 
slow" thought.  While at the show I spoke to Keith Childs he of mechanical 
fan (electric back-up which he says never comes on) and aluminium radiator 
fame.  He reckons that the ally rad is the reason for his machine 
running  so cool.  So can anyone tell me just exactly how much better an 
aluminum rad is.   I see that the coefficient of thermal conductivity for 
aluminium is half that of brass.   My rad is the D&D one which I believe is 
brass.    Are the pipes bigger, thinner, more or what?
