What is the difference between a racing radiator and a regular radiator?
The differences between regular radiators and racing radiators are vast. The most obvious difference is that racing radiators are all-aluminum, meaning that the headers, the tubes, and the fins, are aluminum. Complete aluminum radiators are resistant to much higher pressures (the hotter the coolant, the higher the pressure), they are lighter, stronger, and can handle very hot high-revving engines for extended periods of time. In other words, they can endure a level of abuse that conventional radiators cannot. The way in which they are constructed varies from manufacturer to manufacturer. Some manufacturers use higher grade aluminum and higher grade solder. Welds can be heli arc or tig and the quality, smoothness, and detailing of the welds vary. Some are brazed in state-of-the-art furnaces to bond all materials while others are not. The type of radiator that is most suitable for a car depends on how that car is driven.
