unless you are always travelling at over 100km/h a 3 core alloy radiator would be a very bad choice for a street car.
Alloy dissipates heat about 4-5 times better than copper/brass core radiators, and this is why they are and can be much thinner than copper/brass radiators. If you make them too thick, air doesn't travel through them as well and it actually impedes their cooling ability on street cars where they dont have high wind velocity going thru them.
anyone using chinese ebay radiators??????????
