    MSD 6631 Details

    Professional race teams have been relying on the power and endurance of our 6 HVC Ignition Control and will be excited to see the addition of a rev limiter! The 6 HVC-L Ignition has a built-in rev limiter that will save the engine from overrev damaged caused by spins, missed shifts or driver misfortune. This means there is no need to mount an external rev control (i.e., less wiring and reduced weight)! The advanced component design and circuitry of the 6 HVC Ignitions produce incredible voltage with high current output. Internally there is an efficient heat sync, solid component mounting and its all encased in a clear epoxy. The rpm limit is adjustable with plug-in modules and the wiring is routed into NASCAR approved Deutsch style MSD connectors.
