    Autometer EGT probe safe in the manifold??

    I am planning on tapping my manifold this weekend. I have the Autometer Pyrometer (Sport Comp) and will be using the Autometer probe. I have heard some bad things about these probes melting and/or breaking off and going into the turbo, but no real hard evidence. It mostly seems like NASIOC snobs trying to stop Noobs from buying USDM gauges instead of JDM gauges more than anything. I figure that the gauge is set up to read at most 1600 F, so the probe must be able to handle much more than that (I forget what the factor is but all probes and gauges are always set up for like 20-30% more load than they read). I have seen Autometer gauges in tons of race cars, pro sreet cars, and the like. I do not think these guys would be using these gauges if they were faulty. I also do not want to put it in the downpipe because the readings are not very accurate and I do not want to have to be adding 200? 250? 300? degrees to my temp all the time.

    What is everyone's opinion on this?

    Yes, thanks. I have read that thread about 8 times now. I just want to hear from anyone that has actually had the experience of a probe failure, and if there is no one out there, then I will deem it to be a rarity. I did find a thread on NASIOC about a greddy failing in the manifold (but it was installed too close to the head -- user error), so I see no reason to trust Greddy (or any other JDM for that matter) over Autometer, and scores of people have put the EGT probe (USDM and JDM) in the manifold without any problems -- all but one as far as I can tell from actual accounts.

    I have the same Autometer Pyrometer gauge. I installed the probe into the driver's side manifold. The highest temp I ever see is 1500... stock car. Since the gauge can read to 1600... I'm quite sure the probe won't disintegrate/melt till well above that.

    Here's a pic of my probe install. Works great!

    What exactly does it mean to "tap" the guage in your manifold? Are you drilling a hold in it, and how will you be sure to get it fine enough where there is no leaks.

    use a 1/8-27 NPT to cut the threads. Its tapered so it wont leak. In that pic above, thats right where i put mine and it works great. I cut a hole in the heatshield so it can come through and keep the heat down.
