    "Runtz" transistorized reducers allow you to use your original 6 volt electronic devices (like gauges) on a vehicle that has been converted to 12 volts. You will need a "Runtz" for each 6 volt electric gauge on your car.

    Designed for 12 volt negative ground systems only. Screw type terminals. 1.5 ohm resistance, 4 amp max load, 25 watts.

    910-64101 Instructions (PDF)

     

    Note: Never, ever use ceramic block style reducers for gauges, radios or lighting. A power surge will destroy the electronics when first turned on. Ceramic block reducers should only be used to operate 6 volt DC motors and fans on 12 volt DC.

                Our new DynaForce Starter is designed to crank over the highest compression engines on a hot day in Death Valley. Not that too many race cars are sitting in Death Valley, but its good to know that you have the oomph to make it happen. The DynaForce Starter features all new components beginning with a three horsepower motor. This power is used to crank over the reduced 4.4:1 gear set to deliver great torque to the engines ring gear to get the engine turning. The armature is balanced during assembly and is guided by two ball bearings for smooth engagement and thousands of starts. The downsized housing clears most headers and oil pans, but just in case, we made the billet mount so it can be clocked in different positions to help in tight applications. The assembly is powder coated MSD red and will stay looking good, even though its underneath your car.

    • Machined from lightweight cast aluminum
    • Superior belt retention with extra-deep grooves
    • 20% reduction slows accessories down for less drag
    • Adds top-end horsepower
    • Reduces water pump impeller speed below cavitation threshold
    • Improved high-RPM cooling capabilities
    • 910-15488
      • 5-7/16" O.D.

    Available for long water pumps. 5/8" shaft.

    Note: The lower crank pulleys are manufactured thicker than normal stock pulleys.  This requires longer 3/8" bolts to be purchased separately.  Allen head type bolts recommended.
