where in australia can i get a white face, 2" (and a bit) electronic pyro gauge and probe in CELSIUS?

i cant seem to find them anywhere.

cheers

PAUL

Most of the gauges are measured in F, like Autometer, etc.

The only ones I could find in white and celsius are:

But its 60mm.


If you can handle having a gauge with a black face... fair bit cheaper
VDO Pyrometer

This is what I have in my Lux

From www.egauges.com

ausyota, how much was your autometer gauge and did it include the probe? if not, how much extra? do www.egauges.com do online shopping?

cheers

PAUL

does anyone know of a brand of pyro gauge that displays in electronic rather than a dial?

check these out, i have spoke to the people that sell them they sound like a great gauge, with adj temp warning

hope to have one next week

Cant remember how much I paid as I bought a boost and an oil pressure at the same time.
But yeah did the transaction via Email with credit card.
They were a little anal with the security and got me to scan and email my drivers licence, but all went smoothly

I can get you probe kits, no issues

I've been thinking about this and reckon something could be knocked together pretty easily, we use a lot of temp controllers at work (digital) which have the temp readout usually in green or red LED display, these can just give a reading from a K type or similar thermocouple or switch something on or off at preset temps, asked one of the sparkys and he said depending on the material of the thermocouple they'd easily handle 6-700 degrees plus...

heres something similar to what we use at work, couldn't find much info on the one ive got here at home, its a Carel PID controller, use it to control the temp of a pouch for a baby wallaby..

ads80 that gauge looks awsome excatly what ive been looking for how much did it set u back?

about $400 depends on where u are. click on the dealers link and find the closest to u. i think the digital will be much more accurate and faster to respond. and with an alarm u dont have to look at it, just my 2c worth

That's a smoking deal on the VDO. I paid about 50% more and that was with a whopping discount.

I had the same idea, i can buy all the stuff straight from RS and do it all for about $180(i think)

There are a lot of happy users of the thermoguard digital EGT/PYRO
http://www.thermoguard.com.au/index.html

I went to autobarn ages ago and asked about they the guy said $280 for a full pyro guage kit.

No idea what kind of guage it was though.

I've seen some US places selling digital ones that can display F or C single or dual display

Single can hold in memory the highest EGT temp with a button

Dual can have 2 pyro meters or second display shows the highest EGT temp recorded, and some will even record over a certain amount of time and you can play back the temp recording.

But these would be a bit of money like $300 $400 for a kit.

a mate of mine bought a supposed kit from autobarn, it was about $280. and when it arrived it was JUST the gauge. and cost him another $240 for the probe. i ordered mine from egauges.com for US$140 (approx $168) including the probe, and its the exact gauge i want. they have them ALL, so i got a cpl of other ones too and they all match. excellent site, just hope the gauges turn up

thanks everyone

Once you get the guage, where do you put the probe? And don't say in the exhaust, stupid. I mean, where, in the exhaust.

As close as possible to the exhaust ports.

Read the information on the thermoguard page..

Ideally it should be upstream of your turbo, however in the dump pipe is acceptable downstream from the turbo. If your dump pipe doesnt have a fitting in it for place thr probe (unless it is aftermarket it probably wont) you can either drill and tap a hole yourself and get a workshop to do it for you.

i heard it was better pre turbo, as it would be more accurate as to how hot ur engine is running. i will be tuning my motor to EGT's and hear the recommended SAFE max is about 550C (correct me if im wrong please?????). would that be read pre or post turbo. got my gauges coming next week.

That temp would be post turbo, pre turbo its up around 700°C... there is no definate value for temperature loss between pre and post turbo, however reading OL/Thermoguard website would suggest it is about 200°C.

A post turbo EGT reading of 550°C would be on the high side of safe, good for lots of power, bad for longevity and fuel consumption.

Your personal safety factor will vary. But 800 deg is where things start to melt (like pistons).

im guessing thats pre turbo, sounds a lil scary for post?

so im guessing there there is no right or wrong for where the pyro is (pre or post) just that max temp post turbo should not exceed about 550C am i right?

Be the extractors/ pipes coming out of the engine then into the turbo.

Look over for a bold hole or something, I think most extractors actuaully have a hole specially for a pyro probe, but alas some don't and you would need to drill in then tap the hole then screw probe into the hole.

check the threads etc before buying a pryo probe as you'd want it to simply screw in rather than buy one doesn't fit or stuffs up the thread etc.

Most use swagelock type compression olive fittings with BSP threads.
Just make sure you get a steel fitting, brass loses it's strength at exhaust temps and lets go of your probe.

does that still require a thread in the exhaust? or just a hole with compressions type fittings? where would i get them from?

so there is no right or wrong place to put the probe? just that closer to the motor will give a higher reading. but then what would be the max safe temp pre turbo and post turbo?

Yes these require a pipe thread to be drilled and tapped into the exhaust manifold.
My VDO gauge needs a 1/4 inch BSP hole and thread. The kit came with a prethreaded socket that can be welded to your manifold (if steel) and then drilled through.

Yes closest to the exhaust port is best, but anywhere pre-turbo is fine.
For me 750 deg C is the sane limit.
Post turbo is a guessing game, the temp drop across the turbo depends on many factors and can't be accurately predicted.
200 deg C drop is probably at the high end which makes 550 deg C a safe bet.

i should have clarified because i only just realised this is in genral rather than make specific. i have a turbo diesel 4.2L patrol. non intercooled (at this stage). would 750C still be safe? higher or lower?

im going on your advice kiwibacon and will install it pre turbo. its an autometer gauge and hasnt arrived as yet. have a steel manifold so hopefully will be easy. in the dump pipe there are already some threded holes (with bungs in them) which would make it really easy. but im sure not everything is meant to be.


PAUL

Just been for a drive in my GQ after turboing it and installing the pyro, I've got a VDO pyro, works fantastic, it is installed preturbo. I wasn't giving it much throttle and it isn't tuned properly yet but the pyro was getting up round 500 going up a fairly long hard hill, very happy with the pyro set up.

I just odered two set of "Mr Gasket" pyrometer and boost gauges(2 1/16th) from the states, they are made by autometer and are the lunar series, just instead of saying "LUNAR" they say "MR GASKET"

All fittings inc probes and wiring to my door $228
