Patriot EGTS Installation

 

Patriot SpeedCo high speed temperature sensors are more sensitive and fragile than other thermocouples. Care must be taken to make sure you do not damage the sensor tip during installation.

 

Assemble the nut, stainless crimp collar and brass cone onto the sensor as shown in figure 1.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Pay attention to the direction of the stainless crimp collar. This is the piece that will lock onto the body of the sensor. The brass cone will not lock onto the sensor so be careful not to lose it if you remove a sensor.

 

DO NOT install the sensors too deep into the pipe. This will cause the sensor to heat soak quicker and slow the cool down response rate of the sensor.

 

Remove the headers from the engine so you can see how far each sensor is protruding into the pipe.

Make sure there are no burrs from drilling the sensor hole on the inside of the pipes. Even a small burr can effect the sensor reading.

Insert the sensor and set the sensor tip depth from the inside of the exhaust pipe.

 

Use a 3/16 (0.187”) drill or Allen wrench as a depth gauge. Partially torque the nut to hold slight pressure on the compression fitting while you get the depth right. See figure 2.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

For best results and the most consistent data all of the sensor tips need to protrude the same distance into the airflow.

Torque the nut to a minimum of 140lb/in, this will lock the crimp collar onto the body of the sensor and permanently set the depth.

It is acceptable to torque the nut as high as 240-300lb/in or 20-25lb/ft but the chance of distorting the weld bung increases.

Please be aware that the brass cone will not lock to the body of the sensor like a standard compression fitting. Take care not to lose the cone if you remove the sensor for any reason.

 

The tip of the sensor MUST be inline with the air flow of the exhaust gas as shown in Figure 3, (+/-)15°.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The sensor has been designed to withstand the high pressure exhaust gas pulses when INLINE with the air flow (one leg of the sensor in front of the other). Deviation from this will decrease the lifespan of the sensor dramatically.

Do Not be concerned with the sensors being parallel to the cylinder head they need to be orientated so the tip is INLINE with the direction of the exhaust gas flow.

 

Do Not remove a sensor and install it on the opposite side of the engine.

 

Do Not turn the sensor 180° in the pipe and allow the exhaust gas to flow over the sensor from the opposite direction. This will dramatically reduce the life of the sensor.

 

On some applications you will need to rotate the sensor out of the way to access the spark plugs, if so remember to always rotate the sensor back so the tip is inline with the air flow.

 

The Tip is perpendicular to the bend in the sensor body so it is easy to visually inspect the alignment with the air flow without having to remove the header.

 

Patriot SpeedCo sensors are designed to work with any data logger or ECU.

There is no calibration needed but you should expect to see a higher exhaust temperature reading due to the fact that these sensors have a much quicker response time.
