rOTOr PHASIng
Rotor Phasing is defined as the alignment between the rotor tip and the distributor cap terminal when
the spark occurs (Figure 4). This position can be very important to your engine's performance. If the
alignment is incorrect, the spark will jump to the next closest terminal or another ground resulting in
a misfire and loss of power.
Since the timing is going to be controlled electronically, it is important to position the rotor phasing at,
or near the total timing (most advanced). Some race applications with timing retards due to nitrous
or boost should split the difference of the retard amount when setting the rotor phasing.
ADJUSTmEnTS
The PN 84211 Rotor provides 20° of adjustment
(at the crank). Adjustments are easy by
loosening the rotor screw and using a flatblade
screwdriver to clock to rotor top (Figure 5).
