The MSD 6T Circle Track ignitions are the winningest ignitions in stock car and road racing. To stand up to the severe racing conditions, the capacitor and transformer receive additional bracing, and all of the circuits and components receive an extra-thick coating of Humi-Seal, to give even more vibration protection. Add a set of sturdy vibration mounts, and you have one of the toughest ignitions on the market. The 6T series ignitions feature a special 4-pin wire harness, designed to plug directly into an external rpm limiter or the MSD soft touch engine control. They'll work with virtually any 4, 6, or 8-cylinder engines.
The MSD 6TN and 6ALN ignitions are the ultimate choices for superior performance in harsh racing conditions. With sturdy vibration mounts and CD circuits encased in a clear two-part silicone elastomer, they are virtually vibration-proof. A specially designed, weathertight, 6-pin connector meets NASCAR's 20-6.1 ignition wiring rule and provides a tight, positive locking connection with individual seals to keep dirt and moisture from each connection. The 6TNs are equipped with a special 4-pin connector that plugs directly into an MSD soft touch rev control, while the 6ALNs have a built-in rev control. These rev controls are adjustable with plug-in modules, and will save your engine from overrev damage caused by missed shifts or driveline failures. They'll work with virtually any 4, 6 (even-fire V6 only), or 8-cylinder engines.
The MSD 6 HVC CD ignitions are a powerful new system 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, 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 directly plugs into MSD's Soft Touch rev control, which is available separately.
