MSD 8202 Blaster 2 Ignition Coil

  • Special 100:1 windings, kept cool in an oil filled metal canister, are used to provide maximum build-up of voltage
  • The tower assembly is molded of durable alkyd material due to its high dielectric characteristics while wide spaced brass primary terminals prevent the possibility of spark
  • 100:1 turns ratio and lower primary resistance produce high voltage output
  • MSD Red metal canister is filled with a premium grade oil for cooling
  • CARB E.O. Approved
  • Turns ratio:¬† 100:1¬†¬†
  • Primary resistance:¬† .7 OHMs¬†¬†
  • Secondary resistance:¬†¬†4.5K OHMs¬†¬†
  • Inductance:¬†¬†8¬†mH¬†¬†
  • Maximum voltage:¬† 45,000 Volts¬†¬†
  • Peak current:¬† 140¬†mA¬†¬†
  • Spark duration:¬† 350 uS¬†¬†

 

MSD 8213 Coil Bracket

  • Offers easy, univer¬≠sal mounting for standard size ignition coils up to 2-1/4" in diameter
  • Uses a bolt and nut combination instead of the easily stripped self-tapping screw common on other brand brackets
  • Perfect for canister type coils
  • Adjustable from 1-3/4" to 2-3/8" with slight bending of mounting tabs

 

MSD 31229 Super Conductor Plug Wires

  • Engineered from the inside out, the 8.5 offers everything you have everwanted in a wire; incredibly low resistance without electronic interference
  • In a single 12 inch length of Super Conductor Wire there is only 40 - 50 ohms of resistance
    • The lowest resistance of any helically wound wire
    • Copper alloy conductor is used due to its great voltage carrying capabilities
    • The low resistance results in less loss in spark energy so more reaches the spark plug
    • The conductor is wound extremely tight around a special center core -¬†over 40 feet of conductor wrapped into a single foot of plug wire
    • This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) "choke"
    • This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle
    • Outer sleeve that surrounds the conductor features a proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears

 

Notes

Designed for racing blocks with maximum increased deck height such as Alan Root, Merlin and Rocket Blocks.
