| Utilizing such technologies as a top-bottom feed core, custom mandrel bent plumbing, and innovative cast endtanks with internal vaning, the APR intercooler has produced excellent results in testing. The highlights of the APR Intercooler kits include the following: APR Cast End Tanks with Internal Vaning Top-Bottom Feed Bar and Plate Aluminum Core Mandrel-Bent, Powdercoated Stainless Steel Plumbing APR Custom Silicone Intake Hoses All Associated Bracketry and Hardware APR's front mount intercooler kits need at least 13" of vertical clearance to be installed properly. See image showing vertical dimension. See notes below relating to your specific application: - For the Audi 180 and 225 TT, very minimal trimming of the inside of the stock bumper cover is needed. APR TESTING: The conditions of one test that was performed is as follows: at 20 psi of pressure with a vehicle speed of 70 mph, and an elevation of approximately 500 feet above sea level. Under these conditions the internal flow was measured at 720cfm. Also at those conditions, with an input temp of 240 F, the intercooler was quite effective; cooling the output air to 126 F. While doing this, the intercooler measured a pressure drop of only .58 psi. Equally as impressive with the APR intercooler was the external pressure drop (the amount of air pressure behind the intercooler) of only 1.01 psi. This helps to allow airflow to other critical parts of the car such as the radiator and A/C condenser. While the internal pressure drop is important, the external pressure drop is often overlooked. Most other intercoolers commonly cause 1.5 to 2.0 pounds of pressure drop, hindering the radiator from effectively doing its job of cooling the engine. |
