IGNITION AMP MSD 6BTM BOOST TIMING MASTER

Maximum power, no detonation risk. The MSD 6-BTM ignitions are ideal for engines with a turbo or supercharger. Not only will they benefit from multiple sparks, but there is also an adjustable boost/timing retard to prevent detonation. The dash-mounted control knob lets you easily adjust the amount of timing retard from 0-3 degrees per pound of boost. Dial away engine-damaging detonation by retarding the timing in relation to boost pressure, and run on the threshold of detonation for maximum power and efficiency. You also get overrev protection from the soft touch rev control. For use on 4, 6 (even fire only), and 8-cylinder engines using a distributor. Rubber shock mounts and 3,000, 6,000, 7,000, and 8,000 rpm plug-in rev limit modules included.
