| New APS D/R Series 500 Front Mount Intercooler System |
|
Professionally engineered performance for 300 - 500 horsepower applications utilizing 30 - 50 lb/min turbochargers.
The legendary APS front mount intercooler has quickly become the benchmark for all front mount intercooler systems for the Impreza WRX. Extremely high flow rates and massive temperature reduction - a level of performance that other manufacturers can only aspire to achieve. APS has now upped the ante with the release of the D/R Series front mount intercooler system specifically designed for daily driven, high horsepower MY01/MY02 Subaru WRX and STI vehicles. Unlike other systems that require cutting of structural components at the front of the vehicle, APS has designed the D/R Series FMIC with a truly bolt-on replacement unit that not only maintains the structural integrity of the vehicle, but also forms the perfect mount to accommodate the FMIC itself.
Another bonus for the Subaru performance enthusiast is that the APS D/R Series FMIC maintains the standard fog lights!
In the case of intercooling, where bigger is better, APS shoehorned the intercooler core with the largest surface area possible into the WRX for maximum cooling capacity and engine performance. With intercooler core dimensions of 9.5" x 33.5" x 2.5" (24.1cm x 85.1cm x 6.35cm) for a surface area of over 318 square inches (the largest by far of aftermarket WRX and STI intercoolers) and a total intercooler core volume of 796 cubic inches (13023 cm3) that's over 3 times the size of the standard top mount intercooler - and along with the APS intercooler core being of internally finned construction it offers significantly enhanced flow and heat exchange performance over the standard intercooler. Also, unlike other manufacturers of WRX intercoolers who reduce cost by using deeper cores of small frontal area, the APS D/R Series intercooler is designed with the maximum surface area possible (over 318 square inches!). This larger surface area results in the maximum volume of ambient cooling air through intercooler core - For the Ultimate in Charge Air Cooling at high boost pressures. However, there is more to intercooling than size alone. Fully engineered cast aluminum end tanks ensure optimum charge air distribution throughout the entire cooling core for maximum charge air cooling and minimum pressure drop. The reality of intercooler excellence in terms of performance equals:
In other words the greatest possible charge air temperature reduction with the lowest possible pressure loss at the rated flow of the turbocharger - Whilst maintaining excellent throttle response.
By utilizing the latest intercooler core material, construction and manufacturing technology, APS has also reduced the weight of the new D/R Series FMIC by an outstanding 27% - an important consideration for the performance enthusiast who not only enjoys a fast car, but also one that handles well. An intercooler drops the charge air temperature, which enhances the combustion of the air/fuel mixtures. This more complete combustion of air fuel mixtures produces higher engine power. Intercooler performance is measured by the amount of energy (temperature) the intercooler can remove from the inlet charge air as well as the pressure drop across the entire system. It is important to consider the entire intercooler system and not simply the intercooler core itself. At a genuine 400 hp (298 kW), the APS D/R Series FMIC reduces the charge air temperature from 347 deg F to 104 deg F - an outstanding 243 deg F temperature reduction! Also outstanding was the minimal pressure drop across the complete intercooler system. At 7,200 rpm with the pressure measured at the turbo and again at the inlet manifold resulted in just over 3 psi drop in inlet charge pressure. That pressure drop includes the restrictive throttle body! Truly outstanding intercooler performance for high horsepower and maximum engine protection.
