Egt Gauge Reaction Time
Anyone out there with extensive time with different EGT gauges? I'm interested in the reaction time of the EGT gauges. I installed a WESTACH 2C2 today and was a bit miffed with the reaction time. Let's say you go full throttle and then let off...the temps in my opinion should change and go lower RIGHT NOW not a minute or so later.
I've a Fluke 52II temp meter that I watch the inlet and outlet temps on the intercooler and that meter/probes change lickity split when you advance the throttle or let off. So....are all EGT gauges slooooooowww?

I think the EGT gauge you have is based on a general aviation gauge intended for internal combustion engines operating at a constant rpm. However, I think the gauge should be reacing a little faster than what you have stated. Westach has an email help system that you may want to try out to see what they say.

I might call Westach. Then again I might be off base. I'm used to a digital temperature meter. So it might just be analog vs digital. I'm considering buying what I think is a *E* type thermocouple for the Fluke and mounting that somehow. Maybe I shoulda done some research prior to buying a EGT gauge. I bought two senders/probes and I'll try the other one to see if there is difference b/t them.
Located it about four to five inches from the turbo.
Yo, those Pratt and GE use alumel/chromel TIT sensors and they work plenty good fine.

An example of what I call FAST, is taking some FREEZEMIST and aiming at the *K* type thermocouple on the Fluke and letting a blast go for a moment. The meter will register a minus thirty whatever in a heartbeat. Not two or three seconds, but a heartbeat.

When i purchase a EGT, i will definitely be looking into the aircraft market, rather than the automotive. Time to Break out the Aircraft Spruce catalogue. It'll be a good start.

There is a lag, but the lag you describe sounds overly lengthy.
Autometer offers three types of probes, and the cheapest one lags pretty bad. The other two seem to work fine enough. I use only Japan EGT gauges, and their reaction is fine for my tuning uses. They typical react within half a second or so.

BTW, the temps will not lower as fast as they rise. This is due to some radiant heat soak. If you are noticing that it takes a minute for the EGT drop down to ambient, then this is normal. If you are saying that it takes a minute to show any reduction at all, then this is too slow.
