EGT probe placement on S5 N/a with full exhaust...
 

Hey guys, I just got my EGT guage from a forum member today and am getting ready to try it out soon. I want to know if any of you N/a guys are running EGT guages and where you all put them. I have true duals so its going to have to be only for one rotor. I am thinking of getting a second guage(same model) and running dual probes/guages just to be on the safe side. I was thinking of putting the probe in the first few inches out of the rear rotor's exhaust tube on the header. My reasoning for this is that the rear rotor must see the hottest temps therefore I should use this as the data collection point for safety reasons for my engine. My guage didn't come with a bung but I am going to find a nut to use for it at a hardware store or something, what type of nut do you all recommend I get since it will be installed on my RB header? I was thinking regular steel nut because I don't think SS can go onto mild steel with a welder :/

in case you all wanted to see which one i got. :p

I typically mount mine about 6-8" back.

cool thanks for the input J

Dang I need to rehost that pic and resize! lol

I am thinking of putting the bung in in either the red or green dot a few inches behind the O2 sensor. What do you all think?

shoulda gona all out for the Wideband its pretty cheap at the rx7store

i'm going to be using both hopefully!

Ok anyone else using the greddy egt guage know what the thread pitch is on the bung?

I've found something that fits onto the probe's fitting. The thing is that it is a brass fitting. I am almost sure that you cannot weld brass onto steel, right?


Santiago

you could weld SS onto mild steel...if you're good ;) brass though? :eek:

closer the better for accurate EGT readings.

My friend has the greddy Egt, he might know the pitch

If you could ask i'd appreciate it very much! As far as I could tell its either 1/4" or 1/8" plumbing thread.

Well I found out that the probe from Greddy is npt so I have to find an NPT coupler or nut to get welded in there. sigh

I just used the hose clamp style from Westach

You Just drill a hole, insert the probe and tighten it down. Its not Greddy but they use it for airplanes. They probably sell the probe for your gauge. I think of a EGT as indication only. Down stream of the O2 is a standard mounting location.

wow nifty
