MSD

For drag racers, the MSD 7AL-2 has long been the standard ignition due to its reliability and power. By combining the 7AL-2s high performance with the proven digital technology from the Digital-6 Plus Ignition, MSD once again raised the performance ignition standards by introducing the Digital-7 Plus Ignition Control. State-of-the-art technology allows the 7 Plus to produce more power while using the same amount of current. The CD circuits combined with an IGBT Coil driver deliver 520 - 535 volts to the primary side of the coil with up to 190 millijoules of energy at any rpm. Below 3,300 the 7AL-2 produces a powerful series of multiple sparks, rather than a single spark, burning in the cylinder for over 20° of crankshaft rotation resulting in improved combustion and increased power. Inside the gold housing is a 15 Megahertz microcontroller, the fastest of any digital ignitions. The controller analyzes up to 15,000,000 critical instructions per second to produce the most accurate timing control and rev limits possible! There are two smooth rev limits, one for top end over-rev protection and another for a launch rpm. For nitrous applications or for racers looking for a little more mph, a high speed retard circuit is adjustable up to 9.9° using built-in rotary dials plus and a diagnostic LED.

Features

• Two smooth, accurate rev limits are adjustable in 100 rpm increments with rotary dials
• Single stage retard for top end speed or nitrous systems
• Adjustable magnetic pickup compensation for trigger accuracy
• Start retard eases cranking pressure on high compression, engines
