Features & Benefits

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.

  • Great for use on alcohol engines
  • Available in clockwise and counter clockwise rotation
  • Band clamp housing
  • Heavy duty spark plug retainers
  • Perfect middle ground for those who need a bit more current than 12 A but less than 44 A
  • Designed to handle harsh racing conditions
