Expertise - Cooling Systems

Excessive engine temperatures can result in catastrophic failure or premature wear of components. In many high performance and race car applications, cooling systems are used to help control fluid temperatures of engines, differentials and transmissions. 


There are two main styles of intercoolers, air to air and air to water. Air to water intercoolers are less common and are primarily used in applications where air flow to the heat exchanger is insufficient. Air to air intercoolers come in many shapes and sizes and are used in most applications due to simplicity and reliability. 

Achieving adequate air flow through the intercooler is always the first factor considered when custom mounting an intercooler. This can sometimes be challenging on street-cars in order to retain factory components such as bumpers, AC condensers, and body work. Often air flow from a single body opening must be shared with the engines cooling system. A more efficient radiator and/or oil cooler may be recommended to maintain proper engine operating temperature. 

Oil Coolers

Excessive lubricant temperatures can result in catastrophic failure or premature wear of components. In many high performance cars and race cars, oil coolers are used to help control fluid temperature of engines, differentials and transmissions. Usually, in the case of transmissions and differentials, an external pump is used to rotate the lubricant through the core. Oil coolers come in many shapes and sizes and are often selected by space and air flow constraints. Air flow supply to oil coolers is a critical factor of oil cooler installation. Electric fans are often used to achieve adequate air flow when flow from body openings is not available. The addition of oil coolers also increases fluid capacity which in itself, will help reduce fluid temperatures. 


Often radiators on race cars are upgraded with larger capacity cores to combat excessive engine water temperatures. Aluminum radiators are available in many generic sizes and configurations. These usually require some degree of custom installation. Proper air flow to a radiator core is critical. This is often achieved by custom fabricated ducting to maximize available air flow from the front of the vehicle. Electric fans are sometimes used for additional air flow depending on application.
