Description:
The MSD 6 HVC-L CD ignitions are powerful new systems designed primarily for Circle Track and events that require high rpm for a long duration. Only the best high-end components have been put into this exclusive design for more output energy and voltage, with less current draw. Each transformer is hand-wound for more power at lower temperatures. Field Effect transistors accept higher loads than standard transistors. A faster, more efficient Integrated Gate Bi-Polar transistor improves coil saturation. They feature an optimum heat sink that gives increased heat dissipation, large capacitors that give you full-strength sparks at any rpm, a rev limiter, and a clear silicone casing that protects circuits from vibration. MSD wired them with NASCAR-mandated, 6-pin, weathertight connectors and a special 4-pin connector plug that connects directly into MSD's Soft Touch rev control, which is available separately.
