Intercooler flow effects from various end tank designs Author: Albert Raczynski Abstract: This paper will cover the testing of various end tank designs and how they affect flow across the internal cross section of an intercooler core. The end tanks studied are both designed to be used on a 1995-1999 Mitsubishi Eclipse GST or GSX, or 1995-1998 Eagle Talon Tsi, and the Mitsubishi Lancer Evoloution 8, for an aftermarket racing application, and to study benefits, if any, of having one end tank design over another. Materials used are as follows: 1. Spearco 2-216 (3.5”x10.5”x28.0”) Bar and plate style air to air intercooler core 2. 1 fabricated sheet metal “typical” style end tank. 3. 1 cast, smooth volute style end tank. 4. “Squirrel cage” style furnace blower and various metal ducting 5. Davis Instruments “Turbo Meter” wind speed indicator For experimental setup please refer to figure 1. Data from each end tank will be compared with one another, to check for differences in flow and to determine any restrictions present in the intercooler / end tank system. Introduction: About 4 Years ago the only thing that was available for the second generation Mitsubishi Eclipse and Eagle Talon as far as Front Mounted Intercoolers (FMIC) were the Greddy big and small kits and custom fabricated ones, which were usually composed of parts designed for other cars (universal cast end tanks), fabricated sheet metal end tanks, or kits that would require lots of hacking of sheetmetal or extra bends to get a FMIC mounted up to ones car. No installation of a performance oriented aftermarket FMIC seemed to go smoothly. More recently a plethora of FMIC kits began to hit the market. There was, however only one flaw in all of these designs: the end tanks. None of them were optimized for high, laminar, evenly distributed flow, and extremely high boost pressures. Stated best by A.
