Design

APR pioneered the OEM-location direct-replacement intercooler system in 2006. Unfortunately, to the untrained eye, many intercooler designs appear the same. However, effectiveness of the system and overall performance are greatly determined by several key metrics. Alloy selection, end tank design, construction type, fin style, fin density and overall core dimensions must be analyzed and balanced accordingly to deliver class-leading performance. While the OEM’s goal is to create a lightweight, easy to manufacture and inexpensive to produce, cross-platform design capable of supporting factory power levels, APR’s intercooler must be capable of supporting more than double the factory output. Achieving this goal took a multi-step approach focused around intercooler core selection, end tank design and install location.

 

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

3 Quality Bar and Plate Staggered and Offset Medium Medium High $$$ Excellent Cooling Recommended
4 Overly Dense Bar and Plate Staggered and Offset High High High $$$ Excessive Pressure Drop Not Recommended

Core Size:

APR’s Engineers also paid close attention to the balancing act between core effectiveness, pressure drop and space for end tanks through core sizing. With the core too small, pressure drop decreases dramatically, but typically results in a core incapable of effectively cooling. Likewise, with core size too great, pressure drop can increase, resulting in the turbocharger working harder. However, more importantly, with no space for appropriate end tanks, utilization of the core and overall effectiveness of the system diminishes rapidly, negating the benefit of the larger core. APR’s engineers were able to balance each of these characteristics to deliver maximum performance. The APR intercooler system’s core volume, in terms of external dimensions, is 92% greater than the OEM Golf/Tiguan, 78% greater than the OEM GTI and 62% greater than the OEM Golf R Intercooler.

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.

 

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!
