Wondering how to get better lap times or ET out of your racing program? Then consider having your MSD®Ignition 6A, 6T, 6TN, 6AL 6ALN, 7AL2, 7al3 upgraded. The heart of the upgrade is installing faster switching main transistors. There are associated bias parts replaced as well to complete the upgrade service. The process starts with a bench load test to confirm the health of customer’s ignition before starting. A healthy stock box with 12vdc applied will pull to 12,500 rpms, and then fall on its face pulling the right amount of current. After an upgrade is complete the box should be able to run the same bench test. Only this time with 12 vdc applied, a box should now pull to 16,000 rpm drawing 1.5 amps less current. This improvement is across the entire rpm band of the ignition box. This upgrade is like taking a 40lb flywheel off the back of the motor and replacing with a 10lb flywheel. You’re not seeing a HP or Torque improvement the engine is now quicker responding. The cost of this service runs in the range of $125 to $160 depending on the MSD Ignition box.
