Nelson Specialties’ Drag Race proven Heavy-Duty Master switch offers high electrical load capacity, excellent conductivity, and a durable design. Sealed battery disconnect switch is rated to 1,000 cranking amps, and 180 amps continuous – four times the capacity of other master switches. Unit is suitable for electrical systems ranging from 6 volts to 36 volts. Silver-plated contacts provide high conductivity to maintain ignition performance when running low amperage ignition systems through the switch. One-piece heavy-duty die cast metal housing is 2 5/8" in diameter and 4 1/8" long.  Mounting stem is 3/4" in diameter and 25/32" long. Single-pole single-throw wiring terminals are 3/8" studs. Positive switch action confirms proper engagement. Comes with faceplate for clean and functional mounting, as well as high legibility.

Magna Charger Radix Max Superchargers for GM6.0L & 6.2L Vortec Max Engines

Magna Charger’s new Radix Max MP 1900 TVS supercharger uses the same advanced technology found in the new LS9 Corvette and ’09 Cadillac CTSV. Its four-lobe, high-helix design is more efficient requiring less power to drive, has cooler discharge temperatures for increased power, and is much quieter than previous models. The Radix Max system comes complete with everything you need for installation. The major components include a high-velocity port intake manifold with integral water-to-air intercooler and of course, the MP1900 TVS supercharger (available in black powder coating or Chrome Coat). Also, included are new high-flow fuel injectors, and all necessary hardware and specialized tools. A professional installer can install the Radix Max system in approximately eight hours with no modifications to the vehicle. A fully illustrated instruction manual is included for DIYRs.

All Magna Charger supercharger systems carry a Standard 3-Year Limited warranty on the supercharger system, and Magna Charger also offers an optional 36,000-mile/3 Year Powertrain Warranty. For more information visit Magnuson Products on the web at www.magnacharger.com.


The industry’s most efficient, lowest resistance spark plug wire is now available in 100' rolls. This will enable high performance shops and serious do-it-yourselfers to economically assemble custom ignition sets for virtually any 4, 6 or 8-cylinder application using the best wire on the market.

Crane’s FireWire has a rated resistance of 25 Ohms-per-foot, which assures that optimum spark energy is delivered to the plugs. The wire is a state-of-the-art reactive core design, which filters out RFI and EMI “noise” created by high-output ignitions. This protects on-board computer systems, instruments, and audio clarity.

FireWire® also features 8.5mm pure silicone double-layer construction and is reinforced with a Kevlar® weave for extra strength and protection.

As a companion to the FireWire rolls, Crane is also offering five types of boots and terminals in 2-pack or 25-piece bulk packages. They include straight, 90°, 135°, HEI and cannister coil applications. In addition to the new 100’ rolls, Crane FireWire is available in custom-made application-specific as well as “universal” wire sets. These include both “over valve cover” and “under header” designs.

At partial throttle, a negative pressure zone is created on the upper, backside of the throttle blade. This condition creates turbulence that disrupt the introduction of air into the vehicle's intake manifold, slowing airflow, and resulting in less available power. Ultimately, Torque-Curve EFI Spacer's proprietary design improves your engine's performance and fuel efficiency. Improved fuel efficiency can also translate into better fuel mileage, if you can resist the urge to enjoy the sensation of the additional torque in the seat of your pants.

Testing of Torque-Curve's design on a 2004 4.8L GM truck yielded 55 ft.lbs. more torque, and 38 HP more than stock. The same testing also demonstrated 29 more ft.lbs. of torque, and 25 HP more than a well known leading competitor's spacer on the same vehicle, under the same test parameters.

Hamburger's MPFI spacers are 100% CNC machined from 6061-T6 aluminum, come complete with all the necessary mounting hardware, and are backed by a limited lifetime warranty. Spacer models are currently available for GM, Dodge and Ford vehicles, as well as, Nissan Titan and Toyota Tundra Trucks.
