When I run dual electronic ignitions, do I need two P-Mags, or can I run one E-MAG and one P-MAG?
One E-MAG and one P-MAG is what we consider “standard dual configuration”, which should be quite adequate. However, given the small difference in price, many builders are opting for dual P-MAGs. Their reasoning is that one P-MAG is already “required” (in dual installations), so the only question is whether or not to invest $250 to make the second ignition self-powered. One E-MAG and one P-MAG should be fine, but it depends on how you make that value choice.
