MSD 8261 HVC II Coil for 7 Series Ignitions

The Pro Power HVC II Coil is completely built in-house at MSD so engineers have exclusive control over the performance and qual­ity. The coil utilizes an iron U-Core design with a segmented bobbin for improved voltage distribution. The bobbin is molded from Dupont Rynite FR946 material which has incredible dielectric capabilities at high temperatures. MSD also incorporated a cutting edge winding material that has an improved insulation and is also capable of enduring extreme volt­ages. Together, these materials create a durable coil with incredible voltage capabilities, lightning quick rise time and lengthy spark duration. The housing, also molded from Rynite material, features far spaced brass primary terminals and a well protected secondary tower for increased spark isolation. The housing is completely potted with an epoxy compound for vibration resistance and installs with sturdy vibration mounts.

For use with MSD 7 and 8 Series Ignitions.

• Designed for racing applications with an MSD 7 Series Ignition Control
