The hard facts
The more horsepower an engine develops the more heat it creates. Once an engine reaches around 85°C (185°F) you start loosing power and at about 118°C (244,4°F) you could loose 6-7 HP and ultimately risks the threat of serious damage. Cooling problems are a major cause of failures in all types of racing: the radiator is important to the performance and longevity of your racing engine.
How does it work
The radiator removes the engines unused heat. This is accomplished by the fluid which carries the heat out of the engine into the radiator. Once in the radiator the fluid moves through the tube/fin where the engine’s heat is dissipated.
Why an Aluminium Racing Radiator
Although the concept of a radiator is quite simple, getting a radiator to work properly under the extreme conditions of auto racing is not as simple. Most stock motorcycle and automotive radiators are not designed to stand up to the rigors of auto racing—this includes both their strength and performance.
