Introduction: Here at Treadstone one of our main goals is to educate our customers to provide them with the knowledge to safely boost any vehicle they desire. This is why we have decided to introduce “the basics,” which will be a series of blogs that will present information in a simple to understand format with liberal use of lamens terms. Today we will cover the topic of intercoolers, how they function, and their importance. First a few definitions, an intercooler is defined as any mechanical device used to cool a fluid (which is what air is considered to be) typically a heat exchanger that removes waste heat in a gas compressor, much as a radiator does for coolant on modern automobiles. How They Work? At the heart of every intercooler resides the air-to-air core. The air-to-air core is the component of the system that exchanges hot charged air from the turbocharger for cooler air which enters your engine, the cooler the air entering your engine the more horsepower that can be extracted. With three different intercooler cores to choose from; Perforated cores, MDC (medium-density core) and HDC (High-Density Core), Treadstone has the core to suit your intercooling and turbocharging needs. The Difference Each of the three cores has a variety of advantages when it comes to cooling efficiency, pressure drop and Airflow. To achieve this each core incorporates different technologies to maximize performance. To aide in the selection of the core Treadstone Performance Engineering has made a comparison to the three cores we offer. This article shows the difference between each of the cores and a brief summary of the different technologies incorporated within. Also included is the TRE Performance Scale which is for comparison purposes only it measures performance of the core when compared to the other cores Treadstone Performance Engineering offers, not the actual performance of the cores themselves, this helps distinguish each core. When choosing a core it is imperative to choose depending on your goal, when all components are working with each other in perfect automotive harmony producing a mechanical symphony in the form of unparalleled performance from your turbo system. ;) Click Here For More Info!
