The latest coil to be built entirely in-house at MSD is designed to be used with MSD 6 and SCI Series Ignition Controls. This coil utilizes an iron U-Core design with a segmented bobbin for improved voltage distribution. The bobbin is molded from a special Dupont Rynite material and wound specifically to produce the most currentpossible with incredible voltage and lightning quick rise time. The blue housing is also molded from high dielectric Rynite material. The brass primary terminals are spaced far apart and the secondary tower is well protected for increased spark isolation. The housing is completely potted with an epoxy compound for vibration resistance and installs with sturdy vibration mounts. Features: Designed for high rpm, long duration applications using MSD 6 Series IgnitionsNew U-core winding design produces more voltage and current100: 1 turns ratio and lower primary resistance produce high voltage outputWindings are encased in fracture resistant compound for vibration resistanceDupont Rynite housing with isolated tower and brass primary terminalsSupplied with rubber shock mountsNo CARB Exemption Order NumberPit Stop USA offers MSD Blaster HVC-2 Ignition Coil - E-Core - Square - Epoxy - Blue - 44000 V 8253 at low everyday prices.
