Adding Some Spark


Today I ordered my MSD 8261 ignition coil. It’s designed especially for the MSD 7 and 8 series ignition. Below are more technical specs, this thing is a powerhouse. 

             Coil Specs:

  • Turns ratio: 70:1
  • Primary resistance: .016 OHMs
  • Secondary resistance: 30 OHMs
  • Inductance: .250 mH
  • Maximum voltage: 45,000 Volts (Tested with Digital 7 Ignition)
  • Peak current: 2 Amp
  • Spark duration: 150 uS


  • Designed for racing applications with an MSD 7 or 8 Series Ignition Control
  • New U-core winding design produces more voltage and current
  • 70:1 turns ratio and lower primary resistance produce high voltage output
  • Windings are encased in fracture resistant compound for vibration resistance
  • Dupont Rynite housing with isolated tower and brass primary terminals
  • Supplied with rubber shock mounts
  • No CARB Exemption Order Number
