6 BTM Ignition ControlPer Spark Energy: 105-115 mJBuilt-in Rev Limiter (Boost Timing Retard)CARB E.O Number D-40-28Red 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.
Very durable hot spark with timing control (AWESOME)
The MSD 6-BTM is easy to hook up puts out plenty of voltage to weld with although probably not a good Idea and is easy to adjust. I run a 1014hp Procharged pump gas 523BBC. Works Awesome, Thanks Biz!
