At what speed does the distributor rotate?
At what speed does the distributor rotate?
As the distributor rotates at half the speed of the crank when installed in the engine, just multiply by two to get crank degrees.
How is mechanical advance related to distributor RPM?
The amount of mechanical advance is dependent solely on the speed at which the distributor is rotating. In a 2-stroke engine, this is the same as engine RPM. In a 4-stroke engine, this is half the engine RPM. The relationship between advance in degrees and distributor RPM can be drawn as a simple 2-dimensional graph .
What are the parts for a Chrysler ignition distributor?
Chrysler Electronic Ignition Style Distributors Part #’s –SUM-851006 (LA), SUM-851007 (B), SUM-851008 (RB) Notes:This distributor is a HP direct replacement for the Mopar Vacuum Advance Electronic style distributor. This distributor is designed for use with a Mopar style ECU, Wiring Harness, Ballast Resistor, and OEM style coil.
What is the vacuum advance on a Mopar?
Distributor –the primary device, which is adjusted to establish minimum timing. Vacuum Advance –a device that increases or decreases the timing by moving the distributor plate. It is controlled by the amount of vacuum the engine produces. The source of the vacuum is a ported opening in the carburetor.
How is the timing of a Mopar distributor determined?
Total timing is determined by measuring Initial timing (distributor setting) + Vacuum Advance (the setting of the small diaphragm can attached to the distributor) + Mechanical Timing, the advance caused by the weights attached to the distributor plate and controlled by the strength of the springs.

Where is the voltage regulator in a 1985 Chrysler P body?
NOTE: In 1985 and later vehicles, the voltage regulator is controlled by BOTH the Logic and Power modules. In many vehicles, the voltage regulator is in the alternator. • Verify model year of vehicle electronics: Some 1987 P-bodies with turbocharged engines were built with 1986 logic modules.
