Nick Williams Performance Drive-By-Wire Throttle Bodies

Nick Williams Performance drive-by-wire throttle bodies are precision CNC-machined from billet aluminum to meet the demands for increased airflow on the drive-by-wire LSX and LTX performance engines. These throttle bodies require an aftermarket intake to fit the larger diameter throttle blade. They use a 6-pin late model connector that works with late model wiring harnesses. Tuning is required for installation; and the Nick Williams Performance drive-by-wire throttle bodies come complete with stepper motor and electronics installed. There is no need to disassemble your factory throttle body. Order the model designed for your vehicle and engine application.

Magnuson Supercharger Kits

Magnuson supercharger kits make power you can live with! Magnuson's powertrain integration technology offers you the ability to have big horsepower and drivability in the same supercharger. This technology recalibrates the engine and transmission control programs to work with the altered induction path and boost pressure of the supercharger. And that produces a seamless and consistent delivery of power over the entire rpm range--not just the high end! For you, that means Magnuson superchargers will boost your power output, and yet run like their factory installed units. Whether you're driving a Corvette or a Cadillac, a Silverado or a Hummer, or a Camaro or a Mustang, Magnuson supercharger kits deliver maximum performance!

Walbro Electric In-Tank Fuel Pumps

Walbro electric in-tank fuel pumps are available in a variety of flow ratings, including pumps that flow significantly more fuel at higher pressure. The outside dimensions, however, of many pumps are compact enough to fit existing hanger assemblies, without modification. All pumping components have been validated to OEM specifications for use in E85/flex fuel applications. Most Walbro in-tank fuel pumps utilize a proven gerotor design. Some high-performance models, including those designed for engines with more than 750 hp, feature a dual-channel turbine design for maximum efficiency in high-pressure and high-temperature applications. The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that's higher than conventional pumps. Some pumps require modifications to system wiring, fuel lines, and the fuel module, and should be professionally installed. Installation kits including a fuel strainer, fuel hose, harness pigtail, clamps, and wire connectors are sold separately.

Holley LS Modular Lo-Ram EFI Intake Systems

Holley LS Modular Lo-Ram EFI intake systems have a top-feed plenum entry configuration, designed to allow the currently available Hi-Ram 105mm plenum tops to be fitted to a low-profile base intake manifold. The short runner, low-profile base intake manifold intended for forced induction applications and was conceived to package with an air-to-water plenum-mounted intercooler—with a shorter overall height than is possible with other existing intake manifolds. Using a modular design, the top-feed plenum configuration with 105mm top keeps the overall height at just 9.07 in.! Additional features and specs include: * Cast aluminum construction * Modular design allows the use of the included top-feed plenum entry * Designed for GM LS Gen III and IV engines equipped with GM LS1/LS2/LS6 (cathedral port) cylinder heads * Will also work with OE or aftermarket cylinder heads * Designed for forced induction (supercharged or turbocharged) engine applications with peak power at 7,000 to 8,000 rpm, depending on application * Low height to aid the packaging of a plenum-mounted air-to-water intercooler in a top-feed configuration (or to fit under a stock or mildly modified hood in the front-feed configuration) * High-volume fuel rails and mounting hardware included with 3/4 in.-16 O-ring ports (8 AN) * Fuel rail kits come with two sets of brackets—a set for long (usually standard length) fuel injectors, and a set for short (such as Pico or LS7) fuel injectors
