RAD GAUGE
Definition
- The Rad Gauge combines the affects of the air temperature, altitude, and barometric pressure. The gauge is calibrated in percentage points. Its main advantage is that it provides the tuner with an indication of how much the air density percentage points. Its main advantage is that it provides the tuner with an indication of how much the air density changes. The RAD gauge will help a tuner maintain the ideal fuel air mixture. Once the tuner sets the carburetor tuning perfectly, he then sets the RAD calibration screw so the RAD needle is 100%. When the air density changes, the RAD gauge will show the relative percent of change. The tuner can multiply the RAD gauge percentage by the main jet size and determine the corrected main jet size for the air density. (en)
