    DESIGN

    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 were able to maximize performance.



    CORE STYLES

    # STYLE FINS DENSITY PSI DROP EFFECTIVENESS COST COMMENTS RECOMMENDATION
    1 TUBE AND FIN STRAIGHT CHANNEL LOW LOW LOW $ POOR COOLING NOT RECOMMENDED
    2 BAR AND PLATE STRAIGHT CHANNEL LOW LOW LOW $$ POOR COOLING NOT RECOMMENDED
    3 QUALITY BAR AND PLATE STAGGERED AND OFFSET MEDIUM MEDIUM HIGH $$$ 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 system increases frontal surface area by 140.26% and has a 124.31% larger core!

    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.


    INTERCOOLER BRACKET DESIGN

    APR’s mechanical engineers designed CNC-bent and TIG-welded mounting brackets to securely hold the intercooler in place. The brackets make the install extremely easy. With the bumper and factory intercooler unit removed, the APR intercooler installs in minutes without any cutting, drilling or trimming. For the DIY customer, this makes a home install simple, and for everyone else it eliminates hidden costs that often come with a more labor intensive install.


    TESTING

    Internally APR conducted a multitude of tests both on the street and on the dyno with thermocouples and pressure transducers placed at the inlet and outlet of the intercooler during the design phase. Data from these tests were used to chose the intercooler core available today. With the intercooler in its final production form, tests were conducted against the factory to measure the effectiveness of each system. Testing conducted on the dyno provided a semi controlled environment for back-to-back stress testing the two systems. Utilizing a B8 A4 2.0T 6MT at APR Stage II power levels, six back-to-back twelve second dyno pulls were conducted with only 5 seconds of cool down times between runs. APR’s ECU Explorer high resolution data logging system was used for raw sensor data collection. The APR intercooler saw a beginning IAT of 29.25 °C that quickly dropped to 25.50 °C by the end of the first run and settled at only 34.50 °C by the end of the sixth run. The system effectively rejected heat soak and produced consistent dyno results. In stark contrast, the factory intercooler system did far worse. With a cooler beginning IAT of 27 °C, temperature rose to a staggering 42.5 °C after only the first run, already resulting in a poorer IAT than the APR intercooler after six back-to-back runs! As testing continued, it was clear the factory intercooler system was not built with performance in mind. IAT’s continued to rise, ending at 57.75 °C; an additional 23.25 °C higher than the APR system! This translated to a final gain of 17 AWHP over the factory intercooler by the sixth run while the power only varied by under 3 AWHP across all six runs with the APR Intercooler.

    Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynos are for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number.
