The increased out put of the 20 Amp pro-mag was born of racers being racers; always asking for more power. This stemmed from drag racers that were using a 12 Amp system, but just didn't require a 44 Amp system. The engineers at MSD found that with a few changes to the internals of the generator it would deliver the increased current through the same electronic points box, PN 8106. The 20 Amp magneto is a favorite in alcohol slurping engines such sportsman drafters and quick-8 racers. There are three different generators available; a band clamp design in both CW and CCW rotation, plus a model built on a Chevy distributor base. All three require the PN 8106 electronic points box. The band clamp versions are equipped with a large Ford style cap while the Chevy version uses a 4 In. cap and both are topped with heavy duty retainers.
Features:
  • Incl. Cap/Rotor/Wire Retainer/Bronze Gear/Billet Hold Down Clamp
  • Adj. Slip Collar Mounting Flange For Engines w/Modified Decks
