Lightweight internally turbulated tube intercoolers
These are high performance cores, they are light in weight and experience allows you to alter the external and internal finning to deliver the desired cooling and pressure drop. Altering the external finning and tube design will alter the amount of heat rejected into any given airflow. It will also affect the external pressure drop which needs to be considered, especially if items are behind the intercooler which also use airflow to cool. Altering design and quantity of internal finning again changes heat rejection but also pressure drop, some tuners see this expressed as lag. A good standard to checking the quality of your intercooler is weight, heavy intercoolers that contain a lot of mass will soak up heat but be extremely poor at rejecting it, this translates to when you lift your foot off the pedal from a long pull the heat stays in the system so when you re-apply looking for power it will just not be able to deliver it.
There are several more types of intercooler cores on the market, some of them are designed especially for specific requirements such as drag racing or engines with turbos that are used at high altitude. If reading this has left you with questions or you are interested in a one off design to suit a particular need please do not hesitate to contact us and we will do our best to help.
A typical example is our Fiesta MK7 ST180 Intercooler which went through several different designs until we found this square tube internal high flow fin design. It deliveries extreme heat rejection with virtually no pressure drop. When tested against the cheaper bar and plate designs currently being sold into the Ford market place on the third and fourth Dyno run this cooler was over 40% more efficient. Testing showed on a chipped car with intake temperatures of around 140 degrees centigrade this cooler dropped the temperatures consistently to below 35 degrees centigrade.
