1981 GMC C1500 Performance Ignition Products

The MSD 8.5mm super conductor wire is the performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference. In a single 12 inch length of super conductor wire there is only 40 – 50 ohms of resistance. That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it’s great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) or choke. This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. Available in universal kits and bulk lengths.

Hypertech is a technology-driven company with a unique status in the aftermarket industry. Unlike other speed equipment manufacturers that produce hard parts like camshafts and cylinder heads, our core product is knowledge the ability to tune the complex computers that control essential functions in modern automobiles. We have invested in people, not machinery. The knowledge and skill of the Hypertech team are our most valuable assets. Our staff of engineers and technicians has degrees in a variety of disciplines, including electrical engineering, computer science, and mechanical engineering. Hypertech people know computers from the inside out! The Hypertech team is passionate about performance. We have racers, hot rodders, and performance enthusiasts on our staff. You’ll find modified trucks and street machines in our employee parking lot. We build project cars and use our trucks for towing on weekends. We come from different backgrounds, but we have all learned to appreciate the tremendous power of electronic engine controls to improve performance on the street as well as on the race track. Hypertech is the technology leader in High-performance engine tuning computer-controlled vehicles. Electronic engine controls have evolved rapidly since their introduction in the early ’80s. Hypertech has kept pace with these rapid advances in technology by developing power tuning products that take advantage of the capabilities of these electronic controls. Early automotive computers used replaceable PROMs or chips to calibrate the Electronic Control Module (ECM) for a specific engine, powertrain, and vehicle combination. Hypertech created the original Power Chips to recalibrate these electronic brains for improved performance. As the power of digital systems expands, Hypertech will continue to design and manufacture power tuning products that are on the cutting edge of technology.

Top off your GM ignition system with these great new replacement coils. The GM coils have MSD performance in factory style housings. MSD designed these coils by combining our blaster coil experience with e-core coil efficiency. Each coil has a unique turns ratio plus there is lower primary resistance than the stock coil. This all amounts to a bolt-in replacement coil that produces more output voltage. The coils will work with stock ignition systems as well as MSD equipped cars and trucks. Installation tip: If you plan to install an MSD ignition with your GM dual connector coil, use PN 8876 harness for a direct plug-in installation.

Product Features:

• Direct performance replacement for GM dual connector coil
• 100:1 Turns Ratio
• Lower Primary Resistance Produces High Voltage Output
• Works w/Stock Ignition As Well As MSD Ignitions

Hypertech’s Power Coil is capable of firing a street or slightly modified engine up to 7000 RPMs. Voltage gain over stock can exceed up to 57% more output depending on application. Stock coils usually average around 36,000 volts as compared to Hypertech’s coil kits that average between 45,000 and 55,000. Our coil kits include coil, brass terminals, cap, and rotor. Nylon rotor hold-down screws are included to prevent misfire, and our caps are made of high dielectric material to prevent carbon tracking. Each cap fits the distributor housing tightly to eliminate leakage. Power Coil/Caps/Rotors are NOT legal for sale/use in CA.

For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilize the ignition timing. The MSD flying magnet crank trigger system does exactly that by using magnets embedded in an aluminum wheel. The MSD flying magnet crank trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This flying magnet design produces accurate trigger signals and the non-magnetic pick-up cannot be false triggered. Each flying magnet crank trigger includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either the passenger side or driver’s side of the engine (the SB Chrysler and SB Ford brackets mount on only one side). The adjustable bracket provides a wide range of timing adjustment and spacers are included. These systems will trigger MSD 6, 7, 8 and 10 series ignitions and all MSD timing accessories.

Product Features:

• 8 in. Diameter
• Absolutely the most accurate way to trigger the ignition.
• The non-magnetic pickup cannot be false triggered.
• Powerful magnets are embedded in a billet aluminum trigger wheel.
