Negative Supercharging Ignition Timing

OPTION 2: New Mopar Electronic Distributor - Upgraded with early Chrysler heavy advance weight and shaft assembly and fitted with Negative Supercharging advance springs

Send us your Chrysler electronic distributor with the heavy advance weights. We will repair the heavy advance weight and shaft assembly from the distributor you send us and install it into the new Mopar electronic distributor with the Negative Supercharging advance springs. The distributor may be in working or non-working condition, standard or remanufactured but the advance weight and shaft assembly must be in good condition. If you send us a distributor with a bent shaft or damaged advance plate and weights, the additional cost to repair the parts will be added to the total price of the new distributor.

The early Chrysler distributors with the heavy advance weights are the most durable and technically advanced distributors ever made. The heavy advance weights produce accurate ignition timing and prevent spark scatter at low rpm. This allows maximum ignition advance with no pre-ignition (pinging), which produces more power and faster acceleration from idle than the light advance weights used in other distributors.

Heavy advance weights produce more power than light advance weights
The light advance weights used in the new Mopar electronic distributor and other make of distributors produce spark scatter at low rpm. Spark scatter is erratic ignition timing that varies by more than 1-5° at any given rpm and is caused by the torsional vibration of the camshaft. This problem becomes worse with the stronger pressure pulses produced by supercharged applications. Therefore, distributors with light advance weights must use less than the optimum ignition advance to prevent pre-ignition (pinging) which produces less power and slower acceleration from idle. Heavy advance weights eliminate this problem by allowing maximum ignition advance with no pre-ignition (pinging).
