EGT gauge question.. Dumb question, don't hate

[tdotdub]

^ lol yup, never thought of that idea.. But thats a good way to test it

I looked at my probe today.. And I have a feeling this one they want u to weld in a washer and than screw the probe into that.. Its late here.. And I got an exam 7:30 start tomorrow morning.. So I'll post pictures tomorrow and see what you guys thing.. I might be just missing the point!

Hey theman53,  I looked up this micro 1000 and it has a CHT gauge as well. I have a AAZ, how do I hook up this probe if I don't have
a spark plug? It would be nice to see the head temp.
Thanks

search micro 1000 and be done. Guage, probe, and shipping is under 100.00

hate to thread jack, but I would like a CHEAP pyro, but would like it to work Im guessing thats a good luck kinda thing right?

Here's are some cheaper options:

No personal experience. If you try them out, please provide your experience with them.

i bought one of those,but itīs not installed.
will go on a auber digital gauge.

I have been busy, so I was not able to really check out my probe and gauge.. I bought the VDO "kit" Although the more I look at it.. The more I think its not actually a kit... DAMN QMR motorsports.. Anyways different topic...

So this is the gauge that came in the `kit`



This is the probe and how I found it in the bag.. Apears like they want me to weld it in the manifold.. And everyone is telling me not tooo...



This is how the probe looks like when you take off all the fittings off it!



So what do you guys think...

The weld on bung appears to be optional, say if you were installing in your downpipe.  Otherwise just use the dual threaded fitting and tap drill your mani.

Doesn't have much in length on you sensor lead

Are you sure that's an EGT kit? Certainly does not look like it with the temp scaling, and the lack of s.s. braid on the wiring and how short it is.

The scale of the gauge is x10, 250-1650F.  It is indeed a EGT but he's going to have to make the lead longer. 

I suggest taking it to the firewall and affix some form of termination block.  Get 4 new ring crimps like the ones on the lead and extend to your gauge.

Let me preface my reply by saying that my EGT probe placement was chosen because I was afraid of drilling the Quantum exhaust manifold for fear of cracking it and because I didn't know the merits of installing it pre-turbo at the time.

Anyway, because you've got a 5-cyl TD exhaust manifold which you don't want to crack because it's made of unobtanium, you could mount the EGT probe where mine is mounted.  A small block of metal was welded to the downpipe and that was drilled and tapped for the probe's mounting thingy.  I also have the VDO kit.

Someone else can comment but as far as I understand it, EGT readings will be lower than pre-turbo (by ~200-400°F?) and there's a bit of a delay in the readings going up and down compared to pre-turbo temperatures (not just due to the slower VDO kit's probe).

ok, so I did in fact pick up that $30 total kit from ebay, basic digital gauge and the probe, for the $30 bucks, just keep in mind its coming from CHINA. Ive since ordered 10+ other items online including lots of ebay purchases and still havent received my shipment from china, so order plenty in advance.

At the price hes charging, I almost considered buying four of them. lol, would be kinda cool to see real time of each cylinder, would give instant heads up of small issues before they get bigger.

On another note, how hard is it to find a new turbo? and would there be room to install it in the flange of the turbo?

another cool option if the mounting wasnt specific (someone could make them and sell) would be a small maybe 3/4 inch spacer that bolted between the turbo and manifold, pre drilled for the probe.

buy the kits from china 50 at a time (might give you a bulk discount even)  make the flange spacers for the most popular turbo flanges, could even include longer studs with the kit. 
if needed you could possibly make the spacer just a bit thinner by making a weld on bung that doesnt sit between the turbo and manifold and just have the spacer thick enough for the probe to go through, but you would need a long enough probe to still hit the center of your hot gasses

Did you buy the one I gave a link to? You won't know how well it works till you install it. FYI my Auber instruments probe and gauge is also made in China and it works fantastic! Whatever you do, do not install the probe post turbo, unless you do not care about getting accurate EGT readings. I drilled and tapped the 1/8 NPT hole with the manifold on the car by taking the passenger drive shaft out of my 92 Ecodiesel. Don't know if that is possible on your car.

If I have to do it again, I'd probably take the exhaust manifold out. Working from under the car is no fun. You have better control drilling on a drill press than under the car with an 18" long drill bit.

My engine isnt built yet, I plan on installing before assembly, and if I turbo, I plan on installing on new manifold before i install into the car.

cant test it til I get it, lol, 

What kind of temps come out of a gasser? lol,

I have about 20 feet of extra EGT braided SS extension wire, let me know how much you need... You should also get a couple of the yellow connector plugs, they have EGT-specific connectors in them. All over Ebay, a few bucks each. The red wire is the negative lead, by the way, make sure you maintain polarity.

I need about 6 feet. How much?

Five bucks work for ya?  PM me w/ your details & digits.
