alloy rads arent 400 quid are they ?

i got one from ebay, 140 quid, and tbh they DONT make hardly any difference, at least not on my car ....


i am using bonnet raising blocks , and i have removed the bonnet vents also , one gigantic fan on the rad and on an overide switch. just over half way is the most ive ever seen it, even in *this* heat
