Summit Racing™ introduces its MAX-efi 500 Fuel Injector System, the most efficient way to convert your carbureted engine to premier EFI performance. These self-tuning throttle body units bolt directly to most 4-barrel manifolds; then, through their wideband oxygen sensor, the systems continually adjust fuel delivery to provide the optimum air/fuel ratio under all climate and altitude conditions. MAX-efi will support up to 500 hp, and the self-learning ECU allows for easy tuning. With safety in mind, these systems are also designed with a self-adjusting "limp home" mode to protect your engine if a sensor fails. In addition, they include a data-logging feature to track the system while it's running to ensure optimal performance. Other features of the Summit Racing™ MAX-efi 500 Fuel Injector Systems: * Powered by the most advanced self-learning technology available * 4-injector system is capable of supporting stock to 500 hp engines * High-flow aluminum throttle body with four 45mm diameter throttle bores * OE-quality wideband 02 sensor and TPS sensor included * Color touch screen hand-held controller * Billet aluminum anodized fuel rails * Compact external ECU for easy mounting * OE-style harness is clearly marked for easy installation and durability in extreme conditions * All sensors except the wideband 02 sensor and coolant temp sensor are integrated on the unit * Uses commonly available sensors for easy replacement if necessary * System uses a Temperature Manifold Absolute Pressure (TMAP) sensor instead of a MAP sensor, reading both air pressure and temperature * Fits square bore or spread bore intake manifolds. (Spread bore manifold requires an inexpensive plate to avoid leaks. See SUM-G1420) * Works with original carb-type distributor, factory-style throttle linkage, and most 4-barrel intake manifolds

Aeromotive A1000 brushless in-line fuel pumps let you upgrade to a premium unit for faster, more dependable and uninterrupted fuel delivery--with less power consumption and potential for wear or failure. Utilizing the latest brushless motor technology, these pumps are built for sustained pressure (up to 90 psi with Signature models), featuring a bedrock-solid roller vane design that primes easily, reduces friction, and improves efficiency. Producing more torque per watt and a higher torque-to-weight ratio, brushless motors deliver less noise, lighter weight, and more reliability. With a higher level of efficiency (down to fractions of a second in design speed control) Aeromotive A1000 brushless fuel pumps provide precise control of fuel pump RPM as pressure rises—better maintaining operation and flow, while producing a flatter flow curve. These tight tolerances result in less current draw, less heat, and extended life. More product features, items, and specifications include: * Extended service life in ethanol and methanol * Integral, external brushless controller for clean installation, cooler fuel, and enhanced reliability * Inlet and outlet ORB-10 ports * Requires straight 12 VDC to 16 VDC power supply (16 V charge systems require voltage regulator or step-down to 12 V) * Not compatible with pulse modulated systems or fuel pump speed controllers * Includes two stainless steel T-bolt clamps (12703) for mounting * Rated flow of 700 lbs./hr. at 45 psi, 13.5 volts for EFI engines * Rated flow of 900 lbs./hr. at 9 psi, 13.5 volts for carbureted engines * Fuel Injected gas engines rated up to 1,300 HP (naturally aspirated) and up to 1,000 HP (forced air induction) * Carbureted gas engines rated up to 1,500 HP (naturally aspirated) and up to 1,200 HP (forced air induction) * Fuel Injected E85 engines rated up to 910 HP (naturally aspirated) and up to 700 HP (forced air induction) * Carbureted E85 engines rated up to 1,050 HP (naturally aspirated) and up to 840 HP (forced air induction) * Ideal for blow-through carbureted engines up to 1,200 HP
