The 6 BTM is ideal for engines with a turbo or supercharger. Not only will the engine benefit from MSD's full power CD sparks, there is also an adjustable boost/timing retard circuit to prevent detonation. When your turbo or blower forces the air/fuel mixture into the engine, the cylinder pressure inside the combustion chamber increases. The result is a great increase in power but this can also lead to detonation that can result in severe engine damage. The 6-BTM lets you dial away detonation by retarding the timing in relation to the boost pressure. A dash-mounted control knob lets you adjust the amount of timing retard. It can be adjusted from 0° per pound of boost to 3° per pound (up to 15°). The 6-BTM also shares the Soft Touch Rev Control of the 6AL Ignition for overrev protection.Highlights - Ideal for turbo or supercharger
- Rubber shock mounts and 3000, 6000, 7000, and 8000 RPM modules included
- Automatically adjusts spark timing based on how much boost pressure is being produced (increased boost pressure can cause detonation so spark timing must be retarded to prevent engine damage)
- Spark timing retard can be adjusted with dash-mounted knob from 0° to 3° per pound of boost with a 15° maximum
