NOT ANOTHER EGT QUESTION!

[theman53]

Tap into the bottom as it will be easier to deal with I would think. Since it is N/A you could do it right before the toilet bowl.

NPT is National Pipe Thread - it's tapered which is how it seals.
You can get them at Home Depot in the tools section by the drills.

Okay brilliant I'll use a match to verify that it would come off of 700. And then start looking into to drilling the manifold. Do npt fittings require a special tap or just 1/4" ? And I'm guessing the best method is to take off the intake manifold and drill down into the top? Probably can't use my clamp on probe there though...

Most automotive egt probes are 1/8 NPT. Make sure the probe you choose is compatible to your gauge otherwise it won't work. There sre a few types. K is most common, J is another.....and more which I can't remember.

Also be careful that the probe tip, when in the exhaust manifold doesn't touch any touch the manifold itself - as this could give  a false reading.

When I installed mine I generously ground away a few places in the runner to ensure that the probe wouldn't touch. ( although I did my tapping and install with the exhaust manifold off the engine)

As I recall, my Auber instr probe depth is adjustable. Make sure you use the right size drill bit. For 1/8 NPT the tap drill is 11/32 (check to be sure).

[theman53]

I cannot remember but I was thinking the 1/8th pipe was a letter drill, Q comes to mind but that may be for one of the other NPT taps.

[92EcoDiesel Jetta]

Q and 11/32 will both work, they are close enough. Letter drills are harder to find though.

Okay I'm thiinking about just scrapping this whole deal. I mean sure the gauge was a deal but it doesn't cover the range I want and the thermocouple i'm going to replace with a micro-1000 1/8 npt probe anyway. So I might just try to pull it out. test it and sell it on the vortex or something and buy something that suites my needs better.

I know a few people around here are running basic digital EGTs with some success. I'm wondering where people are getting them. They don't fit the interior as well but functionally they are much easier to read and come with max temp alarms and memory recall. Plus they should read from 0-9999 (not really but the gauge has that potential i believe.) I'm thinking about one of these:

or:

http://thesensorconnection.com/egt-probes/meters-displays/superlite-pmd-series-mini-meter-pyrometer-peak-hold

They both say they'll work with a k type thermocouple and should react instantaneously to the changes in voltage from the probe. Just wondering if there is some gauge people have been using with luck as far as the digital ones go.

Edit: After posting i realised this is the auberinstruments egt everyone has been talking about. (i never looked them up) 60 bucks for an egt with a probe is crazy! have people been replacing the probe with the micro-1000 or does the stock one work well?

Thats the auber gages me and others are talking about.  If you don't want to custom mount the gage with exposed wires, they sell little boxes with a grommet you can run wires through the back and keep the unit self contained but it will then take up more room.  They also sell their own cool sensors for temp, pressures, etc.

Also I suggest either a low covered placement or making a shade over the top of the unit, otherwise you can't see it in daylight.

Also even though you can hook a bunch of stuff up to them, each unit can only read one input at a time so sadly it isn't a super computer for each sensor.

I like them though.  You can use the parameters like you are talking about to set off voltage to an alarm(i use an aircraft alarm), and even use that to relays for other functions.  For example coolant temp and a certain threshold as a safety override wired directly to the fan, etc.

Okay question for auber instrument users.

Why This:

Over This:
http://www.auberins.com/index.php?main_page=product_info&products_id=14

They seem to both display egts... both have alarms... both can be programmed to set off an external speaker or relay... both are the same size... I don't understand the difference?

[damac]

power supply?

you can ask them questions, they are helpfull.

also i think just the controller costs about $60 shipped from them if you don't need a sender.

i bought all their senders which are pricey but i haven't had issues with them

[8v-of-fury]

The second linked you posted includes their thermo-couple which I suggest.

I took a video, of mine.. i didnt capture what I am about to say.. but consider this. You can hold your hand around the end of the probe for a few seconds and it will register the raise in air temperature you are making happen with your hand. CRAZY ACCURATE!

I really like the way the Micro 1000 reacts so fast, that is what I recommend. I haven't had the other one you linked so I cannot say it is bad. All I can say is my micro 1000 is basically as fast as your foot on the pedal going up and down on the gauge and that is what I want it to do.

[8v-of-fury]

Did you watch my video? It senses my hand heat as soon as i touch the probe.

[libbydiesel]

Based on your video and testing that I have done, it appears that the auber probe is very good but slightly slower in reaction time than the micro-1000.  It takes 23 seconds for your gauge to reach 1300 and level off.  The micro-1000 will reach 1600° and level off in the same 23 seconds.  In a Mapp gas flame the micro-1000 will peg my Westach gauge at 1900° in less than 9 seconds.  I am not sure how many seconds of the nine second total is the actual lag of my analog gauge - I would guess about half.  Regardless, the auber probe is definitely fast enough that I'd run it rather than replace it.
