Pressure Specifications: Notes
BOOST PRESSURE SPECIFICATIONS
| Ambient Temperature | psi (kg/cm2 ) |
|---|---|
| 32°F (0°C) | 7.3-7.9 (.50-.54) |
| 50°F (10°C) | 7.0-7.7 (.48-.52) |
| 68°F (20°C) | 6.7-7.5 (.46-.51) |
| 77°F (25°C) | 6.6-7.3 (.45-.50) |
| 86°F (30°C) | 6.4-7.1 (.44-.49) |
NOTE:
The boost pressure gauge in the instrument cluster is calibrated to read absolute pressure. When the engine is not running and gauge reads "1", this is normal atmospheric pressure. A reading of over "1" indicates boost pressure in the intake manifold; a reading less than "1" indicates presence of vacuum.
