FAST LSXRT Intake Manifolds

FAST LSXRT intake manifolds are designed specifically for GM truck engines (4.8L, 5.3L, and 6.0L) and LS1, LS2, and LS6 race applications where hood clearance is not a concern. FAST LSXRT 102mm intake manifolds follow the path chartered by the original FAST LSX Gen III intakes by featuring a modular design that allows for easy porting and disassembly and a runner design that yields an incredible 25 peak horsepower gain over the stock intake (on a stock 6.0L engine with a Big Mouth 102mm throttle body). Similar to the LSXR 102mm intake manifold for cars, the LSXRT features the ability to remove individual runners for modification. LSXRT's are constructed from a proprietary precision injection molded polymer which offers many benefits, including lighter weight, greater strength and lower heat soak propensity. While they feature a 102mm air inlet that was designed for the FAST Big Mouth 102mm throttle body, they can also be used with stock 90mm or aftermarket 92mm throttle bodies (78mm three-bolt throttle bodies require an adapter). Other features include integrated nitrous bungs and precise bolt-on fit that permits the use of factory accessories and OEM fuel/emission connections without adjustments or clearance issues.

Aeromotive Dual Phantom Fuel Systems

Today's aftermarket world makes it easy to pick up the phone and order 1000 HP for your street car. This has created several challenges for fuel delivery, ranging from hot fuel handling to pump noise. Aeromotive Dual Phantom Fuel Systems have been designed to solve this problem. They come loaded with two Aeromotive Stealth 340 lph fuel pumps, an additional set of electrical bulkheads, and a larger capacity foam and bladder. The pumps provide opportunity for supporting big power (see power ratings below) while remaining OEM quiet. Separate electrical bulkheads allow for an "on demand" fuel system, which reduces the amount of returned fuel and reduces the tank temperature, making vapor lock and cavitation a thing of the past. Also, this feature is a must when a redundant (back up) pump is needed in extreme conditions, such as off-road, desert, and endurance racing. The larger capacity foam and bladder combat fuel slosh while retaining enough fuel to feed the dual pumps. And the best feature is all of this done from your stock tank with no welding or fabrication! Features: * Two 340 lph Stealth fuel pumps * Supports up to 1400 HP EFI with forced induction, 1700 HP EFI naturally aspirated, 1700 HP Carbureted with forced Induction and 2000 HP carbureted naturally aspirated * Black anodized top hat * Four ORB-06 Ports – two supply, one return, one vent * Larger capacity fuel resistant baffle/basket (includes foam and bladder) * Two universal high flow pre-pump filters * Modular design can be cut to height to fit almost any fuel tank * EFI or Carbureted * Turbine pump mechanisms increase durability

MSD Atomic AirForce Intake Manifolds

When you're serious about power for your LS or new LT1 engine, call in the AirForce! MSD Atomic AirForce intake manifolds have been designed using Computational Fluid Dynamic Modeling to create optimal plenum volume and efficient paths for improved airflow and distribution to stock and modified engines. Their unique bell-mouthed runner entrances maximize airflow and minimize shrouding--efficiently using the available plenum volume for an unobstructed flow path over opposing runners. The 2-piece molded polymer design resists heat soak, minimizes weight, and allows easy access to the runners for porting. MSD Atomic AirForce intake manifolds accept an OEM or 103mm throttle body, as well as stock, aftermarket, or Atomic LS EFI fuel rails. They are supplied with new gaskets and hardware for a direct bolt-on package. The 103mm throttle bore allows the use of large throttle bodies for greater airflow, and a direct-flow path runner design promotes maximum airflow.

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

FiTech Go EFI 4 600 HP Self-Tuning Fuel Injection Systems

When it comes to fuel injection versus carburetors, new school is just too cool. FiTech Go EFI 4 600 hp self-tuning fuel injection systems have the ECU mounted on the throttle body for greater self-containment, clean installation, and easy setup. These trick systems fit any 4-barrel intake manifold, and are designed for use on engines from 250 to 600 hp. They feature a built-in fuel pressure regulator, an ECU that finds the best tune and self-adjusts to it—and the ability to change air/fuel ratios and ignition timing on the fly. Each system has a hand-held controller with a touch screen for initial setup, throttle linkage that suits most transmissions, and is manufactured with OE engineering. FiTech Go EFI 4 600 hp self-tuning fuel injection systems leave the guesswork behind. Order the model with options best-suited for your application. Additional features: * Choice of three fuel inlet connections * Will work with CDI box, but not required to control timing * Adjustable fan control switch * Can be used with an engine-mounted returnless fuel command center * Uses easy-to-replace, GM-type sensors and Bosch 4.2 wideband oxygen sensors * Wet Flow swirl spray annual discharge obtains complete atomization * Voltage-controlling fuel pump control reduces power under low loads to lower temperatures * Systems with mounted ECUs offer spark control without the need for an external spark box or special distributor * Designed for applications making at least 6 in. of vacuum at idle
