Overview

The Holley Premium Mid-Mount Race Accessory System (MPN 20-182) is engineered for serious racers using LS engines. This system offers a compact and integrated design by directly mounting accessories to the water pump, eliminating bulky brackets for a cleaner look and improved engine visibility. It foregoes air conditioning and power steering to reduce weight and complexity for racing applications. Key components include a high-performance water pump with C7 Corvette design efficiencies, a 6-phase alternator for reliable power delivery, and an SFI certified damper paired with a billet 6061-T6 aluminum hard-anodized crank pulley for durability and performance. All necessary pulleys, belt, heater hose adapters, and alternator plug/harness are included for a complete and straightforward installation. The system is designed for easy assembly with comprehensive graphical instructions. It's ready for the racetrack or demanding street use. Steam tube input port is 1/8" NPT.
