MARS Vacuum Meter:

MARS Measures manifold vacuum or crankcase vacuum. Valuable with nitrous systems to indicate detonation. Useful for indication of leaks, warn parts, and malfunctions. Often used as an engine analyzer and tune-up gauge. Indicates if air is being drawn into the system from anywhere other than the carburetor, which adversely affects the air/fuel mixture

When used for manifold vacuum, during normal driving the gauge will indicate vacuum. As you accelerate, the vacuum level will decrease - see "At Idle" and "At Speed" below for trouble shooting.

When used to monitor crank case vacuum in nitrous applications a vacuum gauge can be an excellent indicator of detonation. When detonation occurs, vacuum declines.

At Idle:

• After the engine has warmed up a steady reading of 17-21 indicates an engine in good condition.
• Steady below normal readings indicate a constant leak. The lower the reading the larger the leak. A constant leak could be worn piston rings, a leak in the manifold gasket, leaky or worn valve guides, a hole in the manifold or badly seated intake valve.
• An unsteady pointer indicates poor carburetor function, poor plug condition, or faulty ignition.
• An abrupt drop of 3 to 5 points at regular intervals indicates a missing spark plug.
• Erratic drops of 2 to 5 points are an indication of sticky valves, poor carburator function, or ignition troubles.

At Speed:

• Reading will be lower than at idle but the pointer should be steady at any speed.
• An unsteady pointer could indicate bad exhaust valves, a leak in head gasket or faulty ignition.
• At speeds above 40 MPH an unsteady pointer will show weak valve springs, insufficient valve clearance or faulty ignition.

Caution: When in the "Power Range" (5-10) the engine is "lugging" and you should shift into a lower gear.
Caution: When in the "Coasting Range" (21-30) touch the gas occasionally to bring the vacuum reading back into the "Driving Range) (10-17) or shift to a lower gear to prevent the engine from sucking up oil from the crankcase.
