  • MSD 8154 Replacement Non-Magnetic Pick-Up for Sprint Trigger
    MSD 8154 Replacement Non-Magnetic Pick-Up for Sprint Trigger
    (Part #5478154)
    x
                

    MSD's Non-Magnetic Pick-Ups are engineered for extreme applications. In fact, this Pick-Up was designed and tested on 300+ top fuel dragsters! To live up to MSD's demading expectations in these extreme applications, MSD designed and built the Pick-Up in-house. That way, they can control every aspcet of the assembly and quality. 

    Each Pick-Up is hand wound on a special bobbin and terminated to MSD's tinned conductor, teflon jacketed wiring. These wires are also routed through a strain relief for protection. This assembly is then installed into the precision housing and is potted with a fracture resistant epoxy compound. To ensure that the windings are entirely incased in epoxy, the Pick-Ups undergo a vacuum procedure to remove any air inside the housing. All of these procedures are necessary to product the strongest, most reliable non-magnetic Pick-Up avaiable. 

    The Non-Magnetic Pick-Ups are available in two housing sizes. The 3/4" model is used with MSD’s Flying Magnet Crank Trigger Kits. The 3/8" diameter Pick-Ups are used with MSD’s Sprint Car Crank Trigger systems as well as the professional racing kits from RCD and PSI.

    MSD's non-magnetic pick-ups are hand made to ensure the highest quality. You should always have a spare in your tool box.

    (Part #5478727)
    x
                

    MSD is excited to bring this HEI Rev Limiter to the circle track world. This Circle Track RPM Control is designed for racers and tech officials alike. It features fully digital operation allowing for extra smooth and accurate rev limiting to within a quarter percent of the set value, while eliminating the need for plug-in RPM modules, as convenient adjustable rotary dial’s take their place. 

    • A bright LED display clearly indicates the set RPM rev limit
    • Easy plug-in wiring and connectors allow the unit to plug directly into any HEI-style distributor with no cutting or crimping of wires
    • HEI Rev Limiter is epoxy filled, making it resistant to the extreme conditions circle track racing presents including water, mud, engine fluids and of course vibration
    • The epoxy is also in place so that tampering with the internal circuitry becomes a thing of the past
    • New digital technology also allows the rev limiter to record the highest RPM the engine rev limited for a pre-determined amount of time providing useful information to both race teams and tech officials 
    • If for any reason the unit loses any connection during a race, the engine will lose power and set a fault code that will be displayed on the LED display

    Features:

    • Approved for use in both IMCA and USRA!
    • Fully digital operation allows for accurate rev limiting
    • Rotary dials eliminate the need for plug in RPM modules
    • Easy installation to any HEI distributor with plug-in wiring and connectors
    • Epoxy filled for extreme racing conditions and eliminates tampering with circuitry

    Designed with sprint cars in mind, this MSD Pro Mag unit offers light weight and incredible power. The compact housing also sits an inch lower for improved clearance of the fuel injections plus features a band clamp mount for easier timing adjustments. 

    The electronic points box is the brain of the Pro Mag. It controls the spark duration and the unique full-power firing sequence of the Mag. The energy from the generator is controlled with Field Effect Transistor (FET) technology which is far superior to mags still using points as a trigger source.
