Got Guages??
well, first thing is that you need to sit down with the stock manual and figure out which cylinder is the furthest away from the fuel pressure regulator....this will tell you what cylinder is running leanest from the factory. Ideally, this is the cylinder you want to be monitering your EGT from. If this is not practical, at least you could measure from the side of the engine that runs leanest. Again, all the work we have done so far is with NA cars, so I really have not had a need to go as far as an EGt gauge yet.
I tend not the like the Autometer gauges at all, for anything except boost. I am not a fan of that liquid filled tube they use to do the fuel and oil pressure readings. I tend to prefer the JDM brands, which all use a pressure sensor and simply do their readings electronically. Others might differ..this is just my own personal opinion.
The EGT gauge from Autometer does stink though...I would not sell it to someone if they begged.

My Greddy EGT uses Centigrade and it peaks at 1200 C so that would be 2192 degrees F (multiply by 9, divide by 5, then add 32). It "redlines" at 900 C (1652 F)
Maybe you are just confusing the two temp scales?

At these temps metal may not melt (most often 2kF and higher depending on type), bult they will certainly begin to fail. 1600F is plenty high. Keep it lower than 1300 for sustained used. Lower than 1400 for short periods (less than a minute and not often). Metal does not like heat. Not to mention that the engine will certainly be damaged (gaskets, manifold, oil...)

BTW,
This is what I am looking to place in my G's dash. I had the same in my truck. It can monitors 3 measurements (boost, egt and trans temp or oil press or fuel press - choose when purchasing). The display is thin, 1/2" or so, and has a seperate box that collects and transmits to the display.
It is programable to alarm at certain temps and shows highest reading (resettable). I think the boost, egt and trans for this and a seperate AF should cover it.

And Are you positive 1600 degrees F are not enough to monitor the EGT???1600 F does seem damm HOT??Just a thought?I have not yet hooked up the thermo probe so I dont know what its going to read yet???What is the average EGT in F that it should read normally???
I cannot answer what you temps should be until I know what side of the engine you put it on. Are you precat or post cat? This has a HUGE impact on the final temp you get. The gas you use also has a huge effect on temps as well.

thats just it, you cannot take out the variables...they go a long way towards determining your answer.
Also, define "normal conditions"...your EGT at crusie is far less important than it is under WOT at the top of 6th gear.....
That being said, at the top of 4th gear, you should see a peak EGT of around 820 ish measuring off cylinder #6...that will basically be peaking your gauge, so yes, I would not recommend using it (not only for that reson, but again, due to the high failure rate I have found with the Auto Meter EGT gauges). Again, YMMV

So The Greddy would be better for my application right?Whay are your prices on the greddy???Silver faced EGT...Oh and why would AUTOMETER put out an EGT guage that is 1600 degrees f, that would be soooo close to maxing out???That just dont make sense..
Don't know. Is it for N/A applications and not FI??
My Greddy silver gauge was $220 from Altered Atmosphere.
I think I got mine up to about 850 once but it usually sits around 600-800 C.

good point Dr bonz..maybe its more for NA than FI.. ahev no idea why they do it, but they do. Again, why does all the Japanese brands read to much higher numbers......its just an "oh well" situation.
that was a good hijack man
I will clear the box out now..
