Ok, I getting ready to install an EGT gauge. But my wallet is thin. I did some searches and a few people recommend the Westach gauges and thermocouple found on aircraftspruce.com.
I want to use the termocoupler Jake (fspGTD) recommended. http://www.aircraftspruce.com/catalog/inpages/micro8egt.php
I was thinking this gauge:
http://www.aircraftspruce.com/catalog/inpages/westegt2.php
Does anyone know if they'll work together? If not, can you recommend a cheap one that will? And do I need to purchase any other components?
Thanks!

ive got the same guage :!:
something is funny,cause they dont show the westtach thermocouples
ive got their catalog,its in there
most k types have similar voltage outputs
id call them to be sure first
i may have the box mine came in out in the garage ,with a thermocouple part number

awesome price,and good reaction too

Is that boost gauge from them as well? If so how well does it work? And which one is it? I couldn't find a boost gauge in their website.
-
it's a vdo boost gauge, i have one too, i got it from ap tuning i think.
-
I've heard the VDO's are not recommended. Any opinions?
-
Some people have said that the VDO's are not reliable, but I've had two or three of them in different cars (including one right now on my caddy td) and they've been fine for me. The cockpit style / lighting matches the VW type gauges and they fit perfectly in the 2 1/16" gauge pod holes.
The only thing I did differently with mine is that I got a special tee that reduces needle "buzz" under boost. It essentially takes out the pulsations in the boost "signal" and makes the needle rise / fall smoothly. A number of suppliers sell this tee cheaply, but you can find it at places like ECS tuning...
-
That thermocouple looks like the one I got with Autometer pyrometer. Anyone know what readings should I get with multimeter from the couple? I got 0-1 ohms measured from yellow-earth, red-earth and yellow-red.
For some reason my meter does not work correctly :(
-
try these # s on spruces site
4d2k
712-4d2 may be the spruce part number
those may be the same number,thats a 1/8 npt with a 2.5 inch long tip
a 4d1k (712-4d1)
is a 3/8 by 24 thread instead of 1/8
i used a 3/8/ 24 one once,cause it comes back out of the manifold easy not being pipe threads
its electrical rating on it (both) is
2.5ohms
reads 0-2100f
reads 32.9mv@ 1500 degrees
-
How do you install the EGT gauge? Where does the probe go?
ATD
-
in the exhaust manifold is the best(called pre turbo),which requires drilling and tapping of the manifold
post turbo,or in the dp is easier,but not nearly as accurate,itll lose 2-300 degrees on the reading
-
Pre turbo or post turbo is the best?
I take it the probe comes threaded so you can tap and screw it in.
ATD

Gauge: $48.95 part # 10-01273 (it reads down to below 100*F and so can be used for cool-down)
Does anybody know about other ways of mounting this perticular gauge?
From what I can tell of the pictures, (including hillfolk'rs) the 4 screw front mounting is either part of the housing/permanently attached...
the reason I ask this is because I have (flame suit on) a pillar pod....
so it woulnt fit in the pod I have nor would it be aestetically pleasing :)
any input?
thanks guys

can every egt-meter work together with the thermocouple from aircraftspruce?
i'm thinking to buy one of these aircraftspruce, but i wanna use it on my egt meter (bought on ebay.com) from prosport.

Pre-turbo is a more accurate reading as it isn't affected by the amount of heat energy recovered by the turbo (variable).
I wanted to make a note here. The setup from www.aircraftspruce.com that I would recommend is this:
Gauge: $48.95 part # 10-01273 (it reads down to below 100*F and so can be used for cool-down)
Sender: $23.85 part # 10-01478 (fast reacting with threaded installation good for pre-turbine)
Lighting kit: $4.35 part # 10-01229 (you want to see it at night too)
Total cost is less than $80. Not bad at all.

its exactly what im going to get once the TD is installed
-
I bought this Westach EGT/Boost combo gauge from Aircraft Spruce. It works great. My only complaint is weak back lighting. I tried a green LED, but it wasn't much better.

When I was (much) younger my car felt like a helicopter cockpit to me.. I could almost hear the turbine wind up while waiting for the glow plug light to go out, and would scan all the various gauges in a sequence as "real" pilots do. And of course diesel on a cold morning smells a lot like JP2.
If only I knew about Westach gauges back then.... it would have really completed the illusion !!!

So I suppose you have to take the exhaust manifold off to drill this probe hole? I can only assume you wouldn't want any metal filings getting anywhere near the turbo.
-
Got any pictures?
-
I just ordered the probe mentioned part #10-01478 and was wondering if anyone who had installed one before knew how big a hole to drill into the manifold and what to tap it with? I would like to get the manifold ready so I can put the head on my engine this weekend and then mount the probe in once it arrives.

I believe that part comes in two configurations... 1/4 NPT and 1/8 NPT ?? Best bet would probably be to ask AirCraft Spruce themselves perhaps... would suck if you guessed and the hole was too big.
-
Ya. I might try that. I might just put off putting the head on too until it is here, thinking about it it will make things a lot easier to wait since there are a couple things I still need to do.
-
BTDT... waiting for the thermocouple delayed installing my head by about a week, but I found other stuff to do, and I only wanted to drill and tap once.
-
I would hope its 1/8 (mine was) as a 1/4 pipe thread is pretty big. Tap drill for 1/8-27NPT is an "R" drill but an 11/32 drill will work if you only have fractional.
-
Cool. Ya I looked at my order and it is the 1/8.
-
Should you put any thread lock or sealant etc. around threads of thermo coupler when screwing into the manifold. It will be hot so what if anything will last or work.
-
No need for sealer...pipe threads are self sealing due to being tapered and the fact that the peaks of the threads will actually deform and flatten out against the valleys as you tighten. This also means that pipe threads can only be tightened and losened so many times before they lose their sealing ability.
Edit: I suppose a little copper or nickel anti sieze couldn't hurt but its not necessary.

It looks like the round 2C2 gauge that they now offer goes from 0 or 100 to 1700.
It's not the 700 to 1900 described earlier.
Maybe they replaced the old 2c2 with the 2c2-1,... for the reason suggested here in this post.
http://www.aircraftspruce.com/catalog/inpages/westach10-01268.php
Does that look like the one you got libbybapa?
Part # 10-01268,... $40.80
-
3C2-1 right?
http://www.aircraftspruce.com/catalog/inpages/egtcht.php
-
Now the 32A-1, in the last link I posted is square,...
but the 3C2-1 below it is round, and in the right range
,... but looking closer I see they are both 3 1/8"
I called them today and asked about the 3C2-1 and they don't keep them in stock so there is an added shipping fee,... because it will be drop-shipped.
Thanks for helping me figure this out,.. I'll call and get a price for the 2C2-1 shipped.
It also looks, from the westach.com site, that the 2C2-1 is supposed to be used with the
"For use with 48" type "K" thermocouple"
does that mean the 10-01478 probe that we are using will need a 4 ft extension to work right?
http://www.aircraftspruce.com/catalog/inpages/micro8egt.php
On that link it says:
"Orders gauges, Micro-1000 probes, and extensive separately."
That's supposed to say extension, right?
It also metions"weld-on" or "clamp-on"
Clamp-on is the one we want right? Are we supposed to mention that with the order?
-
sooo. we've covered the probe and gauge,..
What about the wire that goes between the 2.
I edited my post while you were responding to it Andrew.
Does it have to be 4 ft for the 2C2-1?
....and what terminals are used on the ends?
-
They quoted me $56 each for the 2C2-1.
Since it was special order, 3-4 weeks backorder, and would be drop shipped from Westach, they had no idea what shipping would be.
... so I called westach and got a shipping quote,... but bought it through aircraft spruce because it was a little cheaper, and easier to just send one money order.
-
Great info !
My mani. was tapped 1/8" NPT at DMF Diesel during
reassebly a couple weeks ago, pre-turbo right on center.
I'll be ordering up the spuce goose kit ;)
later,

Looks like I'll be getting this set-up for my GTD, only £55GBP (with the updated prices & current exchange rate) which is a great price! I've been quoted up to £200 just for the sender ! then getting the gauge to go with it was another £100... :o
Only hope the shipping isn't too much! ;D
-
Where have you ordered that from then? Direct? may save me a huge amount of work hunting around ;D
-
When my money comes through on Wednesday I reckon I'll be making a cross Atlantic call ;D
Not sure where/what boost gauge to get though, Halfords apparently sell them for about £20 ??? but what quality are they coming from Halfords.... ???
-
im pretty sure pro sport gauges are the same crappy gauges prothe sells. most of those gauges are way too cheap to be any good.
-
Boost gauges shouldn't cost a ton - they're just a run of the mill pressure gauge when it comes down to it. If a $20 bicycle pump can include a perfectly good pressure gauge then paying $20 for just the boost gauge by itself is pretty reasonable!
This doesn't apply to lots of other things - EGT gauges for instance cost more because what they're measuring is more complicated. Also you have to think about what the effect of a faulty gauge would be - a faulty boost gauge probably won't be responsible for your motor getting trashed.
