A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll. One of the keys to making big horsepower with any turbocharged engine is keeping the inlet air temperatures down, to combat this problem in the MKIV Supra we have developed our new Titan Motorsports 5-row Race Intercooler. The foundation for our intercoolers is a proven Garrett bar and plate core that measures a staggering 28×12.5″. CAD designed end tanks which are laser cut for consistency are TIG welded to the massive core.
