Holley manufactures high performance carburetors, manifolds, superchargers, water pumps, throttle body fuel injection and fuel pumps for street and race applications. In producing these parts, Holley prides itself in utilizing the latest technology in a lean environment to provide the highest quality parts at the best value to the customer. CNC programs can be generated on a workstation, directly from a customer's solid model. Each engineering work station is networked to each of the CNC machining centers and CNC turning centers. This configuration provides a streamlined flow of data throughout the factory, as well as data acquisition capabilities. Fixture and tool design can be accomplished in house, utilizing Pro/Engineer software. A computerized PM (preventative maintenance) network application is used to ensure all machinery is performing at the highest level.

Holley's machining departments range from small drilling and tapping centers to large four and five-axis high speed machining centers. Many are equipped with automatic pallet changers to facilitate the highest level of spindle up-time. Also included are CNC turning centers. An in-house tool room and maintenance department is comprised of a CNC wire EDM, CNC die-sinking EDM, Ewag tool grinder, and a host of manual machines.

Earl's Design Temp–A–Cure Oil Coolers

Description:

Earl's Design For many years, professional racers have been using modular style oil coolers almost exclusively. Virtually every Formula One, Indy and GTP or Trans–Am car depends on these type units for engine and transaxle cooling. Temp–A–Cure coolers have been developed specifically for use in all types of engines and transmissions subjected to temperature extremes, including competition and high performance uses. They are designed for the range of air speeds and oil flows normally encountered in automotive use, but built to aircraft standards of quality. They are constructed of high grade aluminum and are completely furnace brazed to insure the most thermally efficient joint possible between the oil tubes and air fins. The internal design of the oil tubes and the large area collector tanks provide maximum surface area with minimum pressure drop. The highly concentrated air fins offer maximum heat transfer to the outside air. Typical Tube & Fin Design The tube and fin cooler has little to offer in the way of efficient oil cooling. Its typical serpentine design has a large pressure drop due to the tube length and to the restricted bends. The tube and fin cooler cannot approach the cooling efficiency of Earl's Fin density and oil side to air side mechanical bond. If the tube and fin serpentine style were the most efficient in terms of cooling, wouldn't you expect to see this design used for radiators on OEM installations and racing cars?
