EGT guage mounting

[edddo]

Hi
Time to put in an EGT..I am getting a theromguard one. Where have people mounted the display guage on a disco dash?

thanks

I hope Ian (Thermoguard) goes not mind,

the kit is perfect for a Disco:

I put mine in the coin tray. Needed to cut it out a little but otherwise it is a near perfect fit and looks factory.

Hi mate;

I recieved my Pyrometer 2 days ago ,but I was Planning to fit mine on the RHS where the ashtray used to, I have switched it's place with the " Blank Plate " that was over on LHS. so that EGT Gauge can be on the driver's side, but it'll be Bit Hard to see it while you're driving and trying to keep your eyes on the Road , wouldn't you agree?

Hi Eddo

Just wondering if you have installed your gauge ? not sure if I'm supposed to power the gauge from the ignition or does it have a On/Off switch, it may sound silly but I wired mine to straight to 12 volts ? :(

I fitted my EGT gauge last week using the blank switch surround under the clock RHS.If you want it on the LHS you can interchange the blank switches with the ashtray or use the coin tray.It is only a question of using a hacksaw and some patient filing of the surround to obtain a perfect fit.I used the upper spare spade terminal[vertical]that is alongside the under dash fusebox next to the door pillar,for the power source[inline fuse].The lead from the sensor goes through a cut on the side of the large rubber grommet that carries the electrical cable to the right of the steering column.Have only seen EGT temp up to 400 so plenty of scope for tuning the pump!

thanks everyone for the tips...I havent got to mine yet , maybe next weekend...no shed....

hi Geoff ,

A pyrometer registering 400 deg would certainly not be under Full load condition , ie Foot flat to the Floor with the Boost gauge registering 15 psi climbing up a Big long Hill, if you are intending to tweek your Pump be absolutely sure that you have done all the required tests prior to this Mod , it doesn't take much and believe me I did it today "to get the Pyrometer to reach 600-650 deg under full Load" so ( Fuel Pump settings is back to original factory settings ) except the stop screw which has been wounded up but this only affects the No Boost to low boost driveability , so under Full Load and Boost gauge up at around 15 psi the extra Fuel charge will cause your EGT to rise much more rapidly and will place you in the danger zone quicker , if you do end up tweeking your Fuel Pump up ofcourse you will immidiately have to back off from pushing the Throttle,also a Boost gauge is also Handy tool to have...


have a good one..

I have heard a lot about the dangers and risks of high EGT's but who has seen or had damage from this, what might be an early sign of running egts too high?

what might be an early sign of running egts too high?



Not quite sure I'm understanding the question?

but I'll try and answer the best way I know how ...Exhaust gas Temperature no greater that 700 degrees for a prolong period , or you will end up Cooking your Engine , you can certainly try it...:) no just kidding...that why some guys here install Pyromters to back off from the Throttle when EGT reaches a max allowable limit of I would say about 650-700 but some people here are more conservative and that's Understandable ,it's big dollars if you damage your engine and not many people these days have a few Grand just lying around to buy a new engine, or completely rebuild their existing Engine... well i certainly don't know of any ...

or if you are planning on Tweeking your Pump do a search on this Forum , This forum has Wealth of Information
on how to adjust your Pump and do it right to avoid any detrimental damage to your engine..and also there has been Numerous Threads on EGT etc.

Correction on my last post.I ran the cable from the sensor through a new grommet in the firewall,used the existing larger grommet for the Engine Watchdog alarm cable....similar box to the Thermoguard, complements it on the other side of the dash[a bit more filing would have seen it flush].Also fitted a low coolant alarm using Rangie coolant cap[PRC7925]and one of Tim's interface modules.Should have fitted them all at the same time and used one hole in the bulkhead to run the cables through.
Thanks Disco Owner re the comments on temperatures.I will certainly do a run up the hills before tweaking the pump....will redline the temperature at 650?

[QUOTE=Disco_owner;639238]Not quite sure I'm understanding the question?

well to rephase my question.....I understand the theory but how many forumites have actually experienced some engine damage from egts being too high...or how many of you have seen this kind of damage? What is damaged first and what engine symptoms might you expect if you overdid it up a long hill towing on a hot day??

Are we talking general overheating symptoms/head gaskets...or something else..like ,melted valves or something??

nice install Eddy ,it really does look factory , so I take it the other gauge is to do with your alalrm , ah you already said ..

I'm yet to work out how to wire the +12 v and gnd for my EGT gauge to the ignition to power the unit so it isn't always on and only switches on with th ignition on , I have't really followed the instruction and that is somthing I probably need to do. shoudl be easy or straight forward.

I'll be interested to know how you went...you can either PM me or post it in here...

The vertical spade terminal between the under dash fuse box and the door pillar is only live when ign is on.The ground was spliced into a wire[white?]that went to a bolt near the steering column.The Engine Watchdog is a temperature alarm,I have mine on the thermostat housing bolt,but guess it could also be used for transmission temp.They are available from www.sig.itel.net
Edddo, the problem with EGT higher than 720 degrees is I believe,melted pistons.Not good.....maybe ceramic coating could provide some protection?

Hi guys,

was just reading and was wondering what is a EGT and a pyrometer dony laugh im just interested

Two Beers...tooheys new i hope..

Exhaust Gas Temperature Gauge ( Pyrometer ) , This device measures how hot your exhaust Temperature is straight out of the exhaust manifold so you don't end up melting your engine / turbo fan Blades pistons / wastegate etc.. when your engine is under full load for prolonged period of time, do a search on this forum , you'll find heaps of threads on the subject of EGT and Pyrometers...


have a good one...

Yes this is what I also hear...but again, who has seen it happen?
