G'day all,

 

 GRTs web site has been off the air for a few days.  Anyone know how far the EGT probes need to be positioned from the exhaust ports?

 

 cheers,

 Ron

I believe most analyzer vendors have a recommendation. EI suggests 1.5

inches below flange. All of my IO-360 stacks happened to have a

witness hole at that distance that was easy to drill for the probes.

Seems to work fine.

Probes may live longer further down the stack. Main critical item is

that all probes are at same distance.

The Garmin G900 install manual (using Alcor probes) recommends: A) 2-4 inches from flange, B) Not on any curved portion, and C) All at the same distance from flange.  I just finished this and it is a challenge to satisfy all the requirements on the supplied exhaust system.  There are a couple more self imposed requirements you might think about:  A) Tightening screw accessible during its full range of adjustment (it moves as the clamp tightens), and B) tightening screw assembly away from spark plug access area for ease of plug maintenance.

Ron,  

   

I haven’t had any issues with their website, if you want a copy of the manual emailed to you let me know.  Here’s the excerpt from the GRT EIS manual on EGT probe installation.  

   

Bob  

   

5.2.9 Exhaust Gas Temperature Probe Installation  

Start by drilling an 1/8-inch diameter holes at the appropriate position in the exhaust manifold as indicated by the engine  

manufacturer. If the manufacturer provides no guidance on the location of the EGT probes, we recommend the  

following:  

1. Position the probe 2-8 inches from the cylinder.  

2. Although not critical, it is preferable to position all probes the same distance from the cylinder.  

3. If possible, position the probes so that they are mounted on a straight (not curving) portion of the exhaust manifold.  

The hose clamps fit slightly better on straight portions of the manifold.  

4. Position the hole around the manifold so that the probe does not interfere with the cowl, and takes into  

consideration practical needs related to maintenance (does not interfere with the access to the oil filter, etc.),  

inspections, or probe mounting.

Dave,  

            Are you installing the G900X? If so do you have a photo of your panel?
