Intercooler Core Design
The APR Intercooler core is a large bar-and-plate design featuring densely packed staggered and louvered fins. This design offers exceptional cooling while balancing pressure loss across the core, and maintaining critical airflow to the components behind the intercooler system. The core size was appropriately matched to the platform, minimizing pressure drop while leaving adequate space for appropriately designed end tanks. To APR’s mechanical engineering experts, the design represented the ultimate in performance, far exceeding the capabilities of the factory intercooler. To the driver, the result is simple: Repeatable performance, even in the most demanding of situations!
Core Style / Internal Fin Structure:
APR’s Engineers paid close attention to the balance between core effectiveness and pressure drop through the core, core style and fin density. With fin density too low, pressure drop decreases dramatically, but typically results in a core incapable of effectively cooling. Likewise, with fin density too great, pressure drop increases dramatically, resulting in the turbocharger working harder, and hotter, to produce the same level of airflow. By fine tuning this often unseen balancing act, as illustrated below, APR’s Engineers were able to maximize performance.
Intercooler End Tank Design
To fully utilize the massive core, APR’s mechanical engineers designed cast aluminum end tanks organically shaped for proper airflow distribution across the entire core. By correctly sizing the intercooler core, end tank design was not sacrificed. The one-piece end tanks are CNC machined to provide a slip resistant mounting surface for hoses, precise integrated mounting surfaces, and perfectly flat connecting surfaces used for TIG welding the tanks to the core. Through proper alignment in welding jigs, each unit is assembled to tight tolerances for a precise and accurate fit.
Pressurized Computational Fluid Dynamic (CFD) Analysis:
APR’s Engineers determined the proper end tank design, for this application, with the help of pressurized CFD flow analysis via the SimuTech Group, and finally through real world testing. During the analysis, the effect of directional vanes were studied to test their ability to aid in airflow distribution. Analysis concluded there was no perceivable benefit on this application as the vanes only added more weight to the system. Real world testing without directional vanes resulted in a +0.5 °C to -0.5 °C temperature spread from the bottom to the top of the core on the outlet side, throughout the various back-to-back tests, further concluding the design maximized cooling effectiveness of the core.
Testing
Internally APR conducted a multitude of tests while choosing the appropriate intercooler core and end tank design. Thermocouples were placed at the top and bottom of the core to measure cooling effectiveness and cooling distribution across the entire unit. Pressure transducers were placed at the inlet and outlet of the intercooler to determine pressure loss across the various units. With this information, APR’s engineers specified the appropriate intercooler core type, dimensions, cooling fin density and made the necessary design changes to the end tanks to ensure full utilization of the entire core.
The end result was development of a system that’s much more effective at cooling compared to the factory GTI and factory Golf R intercooler system. Effectiveness is measured as (Intercooler Inlet Temp – Intercooler Outlet Temp) / Intercooler Inlet Temp. The APR Intercooler system’s effectiveness under the most demanding situations was between 82-83% while the factory GTI struggled at 60% and the factory Golf R at 65%.
Intercooler Placement
Intercooler placement plays a critical role in overall performance. By utilizing the factory mounting location, APR’s engineers were able to design a core featuring a massive frontal surface area and large core volume, which plays a critical advantage over common short and stubby front mount designs. Utilization of the factory location means the core receives a high volume of pressurized airflow spread across the entire unit thanks to the highly engineered factory air dam system. Furthermore, by keeping the intercooler in the OEM-location and balancing core fin density, the factory air-to-water cooling system is not disrupted, which is ever so critical on this platform due to the use of an integrated cylinder head manifold cooling system.
The APR intercooler system simply fits, which helps save on hidden labor charges during the time of install. There are no compatibility issues with active cruise control (ACC) systems and the design leaves room for future engine / transmission oil cooling upgrades for track-going customers. The intercooler installs without trimming any air dams, core supports, or more. There’s no drilling, or permanent modifications to the vehicle. Simply follow the included directions and enjoy!
