MSD Boost Timing Master Ignitions

If you run a blower, turbo, or even a naturally aspirated engine, MSD's Boost Timing Masters allow you to run at the edge of detonation for maximum power output. They can prevent detonation by automatically retarding the timing as your manifold pressure increases. The secret lies in a boost pressure sensor that's inside MSD's solid-state control box. The sensor reads boost pressure through a 1/8 in. vacuum hose attached to a boost pressure source. The result gives you peak power without harmful detonation. A dash-mounted control knob allows you to dial in the retard from 1 to 3 degrees per pound of boost pressure, up to a maximum retard of 15 degrees. Vacuum tubing is not included. These units must be used with an MSD 6, 7 or 8 series ignition.
