EGT gauge --- which one?

as above, what brand EGT gauge do some of you run and how do you rate them?

does it have datalogging abilities?---allowing connection to a standalone
any fancy alarms?
what type of EGTs do you get on idle, cruise and WOT--if possible state boost level and turbo
how fast does it react to temp changes?


i've been looking through a lot of different brands on the net, but now its time to get real world performance feedback. seems there a big price difference between certain brands

i see some read to approximately 1000C, while others read to 1200C.......is it necessary to get a 1200c gauge? or will the engine be already molten by then:eek:

PS- i did a search on here, but not a whole lot on EGT guages

Not had any use of a gauge as of yet. But I wouldn't expect to see any higher than 900deg C, unless running anti-lag EGT's can get into around the 1100deg C mark.

I've seen more than 1100 in a 4efte... with out anti-lag.

I'd say go for any good known brand...defi, greddy, hks, etc.

It's added value to go for a zeitronix, as it can incorporate the uego and some temp readings. So a lot of gauges with only one.

1100C? wow, that very hot

thanks for the replies so far

If thats the case that engine is running very lean!
Even an F1 engine doesn't run that hot, they are around 1600deg F/900 deg C. But remember they have effective cooling.

My 4efte had a new coated mild steel exhaust guaranteed to 1000deg C the coating failed on the short runner cylinder 2 soon after fitting, The exhaust on this runner does not flow as smoothly as it does not point down as much as the others.

After about 1 year I noticed the outer edges, that is the friction side of the other runners were losing their coating. This manifold has slightly smaller dia than the stock head exhaust ports which would make some higher temp due to the smaller volume but it seems my boosting for short periods at lower revs ( up to 20psi around 3800rpm ) was enough to effect the short runner before any of the others.

The AFR's for this were on dyno 12.2 AFR 18psi at 3800 and soon after 12.28 AFR at peak torque.
@ Adam I guess It could be leaning more on the road but I wonder if its heat build up from poor flow at higher pressure similar to the third runner on the stock mani?

I use a defi link in the collector of my zisco mani, still running the ct9 with external wasteagte and emanage blue. Cruising at low speeds it sits at 300-400deg, 500-600 at motorway speeds. On boost 800 -900 deg, the highest peak I've seen is 920deg c.

The gauge reacts pretty quickly - as soon as you put the toe down the temp rises and you can record the peak, set an alram level and record the gauge using the link controller.

I run my sensor just after the turbo just in case the sensor fails because it would make a hell of a mess of the turbo if it went through it, but the chances of it happening are rather slim I just like to be safe, but my plx is also wired into the ECU for turbo protection if the turbo gets to hot the ECU can cool it back down by changing the timing and restricting boost (ECU also does full boost control on mine).

Empty your pm box mate :)
