MSD 8762 Boost Timing Master for MSD Ignition Control

The MSD 8762 Boost Timing Master is an analog timing retard controller designed for forced-induction and high-performance engines running an MSD ignition system. Whether you are running a roots-style blower, turbocharger, or supercharger, the Boost Timing Master automatically protects your engine from detonation by retarding ignition timing as boost pressure climbs.

An internal boost pressure sensor reads manifold pressure through a 1/8 in. vacuum hose connection, and the solid-state control box processes that signal to deliver precise, automatic timing retard. A dash-mounted control knob lets you fine-tune the retard curve right from the driver's seat without opening the hood.

Key Features:

• Adjustable ignition retard from 1° to 3° per pound of boost pressure
• Maximum retard of 15° total — protects against detonation across the RPM range
• Adjustable boost start point — set the PSI threshold at which retard begins (0–5 psi range)
• Built-in boost pressure sensor reads through a standard 1/8 in. vacuum hose
• Dash-mounted control knob included for in-cabin adjustments on the fly
• Straightforward wiring — connects directly to the white wire of your MSD Ignition Control
• Analog circuitry — reliable, no laptop or software required
• CARB EO# D-40-28 — legal for sale and use on emissions-controlled vehicles in all 50 states
• Sold individually; vacuum tubing not included

Compatibility: Must be used with an MSD 6, 7, or 8 Series Ignition Control. Not compatible with factory OEM ignition systems.
