    Default EGT Gauge

    I while back i was looking for a EGT gauges, not madman etc, something that was 52mm round for a pod.

    I installed the Autogauge EVO EGT, and have been very happy with it. Quality is good, brightness control and its either Blue, Red, or both (day night). At R1600 it wasn't the cheapest but also not the most expensive, i had some red dragon thing in before that stopped working and was really annoying, iff it couldn't read the EGT below 200 (when at idle) it would just flash at you, very distracting.

    I'm happy to see you installed it in a similar vehicle to mine. I really didn't want to fit a 52mm gauge and to get a smaller one, is difficult. I might now give it a go. Did you get the pod mounts (or whatever its called) also at Autostyle? Personally I don't like your gauge format that much. I might try another brand.

    Pod mounts are also from Autostyle. They come in double or single pillar mounts.

    One thing to mention, I didn't install the probe in the manifold. It's straight after the turbo in downpipe. I had a larger downpipe fitted and it was easier to put it there, just adjust the figure in your head if doing the same.

    I wasn't keen to drill into cast iron, or put a metal probe in the path of the turbo.

    Keep in mind that post-turbo temps are approx 200C lower than manifold temps.

    I installed a Madman in my Ranger and removed it when I sold it. I don't have a proper place for the Madman, therefore I didn't install it yet. Its very easy to drill the manifold. Its about the same as mildsteel.

    Planning to get EGT but fitting into manifold is problematic. Not keen on removing manifold.

    stuff something on the back if the exhaust to create some back pressure and drill with the engine running. This can either save you time or cost you money

    Why problematic?
    You drill the hole with the engine cold about halfway. Then start the vehicle and drill through. No bits/shavings will enter as the exhaust gas will push it out. Switch it off when you're through to cool down. Put grease (to hold the shavings) on tap and tap the thread. But theres no time for playing since the manifold will heat up soon. I did two on WLT engines without any issues.

    Won't the shavings end up in the turbo? Or is the exhaust pressure enough to push them ALL up through your drilled hole?

    I used a nice strong vacuume cleaner and while drilling sucked the shavings, then when tapped the thread put grease on the tap this collects nearly all the shavings

    Everything gets pushed out by the exhaust gases.

    I have drilled mine pre turbo twice in place with the engine running. The first one stripped after a few years and got lose on me. Then melted the probe into a blob that would not come back out through the hole. So welded it up with new hole slightly further toward the turbo.
    As 4E said, post turbo drops temp easily between 100 to 200deg. Set your alarm for around 150deg lower than normal.
    Mine is set for 650 pre turbo, and I don't care if I have a train up my crack on the road, if the alarm goes off, I lift my foot. But only see alarms with rubbish or low PPM diesel when the van struggles with performance.

    Try keep the thermo couple in an accessible place, I have had to replace mine a few times. These things just don't last. Last one was a Autostyle unit that lasted just over a year with hardly 10K km done. It started giving me stupid readings a few weeks back on a trip to Cape Town. Went to 900deg on a downhill running against compression. Spent the rest of the day in alarm state. So I had to disable it.

    Hi guys,

    Don't want to start a new thread. Though I'd ask here.

    I would like to fit a EGT guage, but once it's in, what are the temps I need to look out for? Above what should be considered dangerous ect ect.
    Or is every vehicle's EGT temp range different?

    As bfreesani said, 650C pre-turbo to be safe.

    450C post turbo.

    The Defender guys used to set their alarms to 720C when the probe is just before the turbo. I did the same on my Ranger. When I get my new EGT gauge, I will do the same.

    EGT temps can run very quickly, and when you are at full boot on a hill with a trailer in tow, things get out of hand fast. I have had a case where the alarm goes off at 650, and just by the time I look down at the Madman, it's already at 750-800deg. If you think you can make the top of the hill quickly, you going to be melting pistons.
    Playing with my fuel screw, I have had it spike on pull-aways in a matter of seconds, and drop back down to 300. Alarm goes for 5 seconds, but when you go look at the log, it spiked at nearly 800. It's frightening.

    I hear what you say. My experience with my 2,5WLT in the Ranger was that the enormous increase rate tapers down when it reached 700C. I never got to 800C. I take your advice to heart and will check when I install.
