INTRODUCTION
In order to get the most out of your Boost Timing Master, driving tests and fine-tuning are required.
You will want to achieve having the highest advance timing for peak horsepower at low rpm when
boost pressure is low, and retard the timing during boost just enough to prevent knocking or
predetonation.
Note: In setting up the timing curve, a hand held Mighty-Vac or similar tool will allow you to simulate
the boost pressure, while you adjust timing at idle.
PROGRAMMING
Cylinder Select: The Boost Timing Master is programmed
at the factory for 8-cylinder engines. It can easily be
modified for use on 4 and 6-cylinder engines. The
number of cylinders is adjusted by cutting the cylinder
select loops. Figure 1 shows the Cylinder Programming
Loops and how to modify the Unit.
Magnetic Trigger: If you are using a distributor with a
magnetic pickup, such as an MSD, to trigger the ignition
system the White Wire Loop needs to be cut (Figure 1).
If you are using the points or amplifier input of the MSD
Ignition Control, this Loop does not need to be cut.
MOUNTING
The Boost Timing Master can be mounted under the hood, but should be away from direct engine
heat sources. Make sure that the wiring reach their connections. Use the Control as a template to
mark the mounting holes. Remove the unit and drill the holes with an 1/8” drill bit. Use the supplied
screws to mount the unit.
