EGT Probes
 

Depending on the cost, I am probably going to order a Stewart Warner EGT gauge. However, what I'm unsure of is which probe to order: Stewart Warner or TRE. I've searched all over hell and I can not find anything about Stewart Warner probes, just people talking about how shitty Autometer probes are. I'm leaning more towards purchasing a Stewart Warner kit simply to keep the entire EGT setup one brand, but am definitely open to opinions.

Here's the gauge I'm planning on ordering along with the different probe options:

...And of course the TRE probe: http://www.teamrip.com/accessories.html

By the way, no need to argue about whether an EGT is needed or not, I don't want to hear it, just interested in a probe discussion.

Thanks

Well as I look around some more, I think I'm going to read further into Omega probes: http://www.omega.com/toc_asp/section...ok=temperature

On the topic of EGT gauges, I had wanted to get the Faze EGT gauge, to mach my other gauges. However, do they not come with the probe too? What all does an egt gauge usually need, and how much is a probe? I am thinking that for 133 for the gauge, it better come with a probe!!

Re: EGT Probes
 

Since everyone's on the subject, I've got an extra brand new TRE probe if anyone's interested.

Re: EGT Probes
 

We may have a new option for a decent reasonably priced probe, I will post up on it later today. I have to confirm a few things.

Re: EGT Probes
 

I hope this is a good place for this next question: I have noticed that some put the probe after the turbo, on the downpipe. That way, in case something on the probe breaks, it's not likely to run through the turbo and wreck it. However, it's further away, and therefore, less accurate. I have seen it placed on the manifold, where the most accurate reading is taken. However, Why place it on one port? Can't the exhaust ports vary a few degrees? Perhaps one cylinder is running a little hotter then the next? Where is everyone putting theres, and why?

Re: EGT Probes
 

Generally, from what I've seen, the probe is placed on the #1 runner. However I read a great discussion on NABR this morning from quite a while back discussing the #2 runner as a potentially better location due to #2 running leanest. The reasoning behind was that for a number of the people who responded, the #2 piston was the first to fail and the knock sensor is located behind #2. Granted you are probably not going to see a temperature difference large enough between the two runners to cause concern so I guess you can go either way. Personally I have not decided if mine will be on the #1 or #2 runner. However if possible, I am going to follow Hill's lead (With his permission since he's the first car I saw it done on) and have the probe placed on the underside of the manifold versus the upper, visible side.

Re: EGT Probes
 

What would the benefit to that be? Why does john shepard place his on the 4th runner? Could you just place it at the collector, right above the turbo?

Re: EGT Probes
 

From what I understand, the benefit to placing the probe in the #2 runner is going to be the monitor cylinder that is most volatile to potential issues. As for tapping on the underside of the manifold it comes down to one reason in my eyes: appearance. I may end up purchasing the stainless heat shield from JM Fabrications so the last thing I'll want to do is drill a hole through it for running my probe wire.

Re: EGT Probes
 

My TRE probe was great; fairly cheap at $45, SS wiring, and very fast reacting.

Re: EGT Probes
 

I have a TRE probe, and it's works great.

Re: EGT Probes
 

Here's the probe Raptor was talking about.

First of all, it has a 90 deg bend, not straight like the TRE.Not sure if anyone cares about that, but I like the bend much better.Its the fast acting exposed junction like the TRE.Sheath is inconel, NPT fitting is 316 SS.It also has 7 feet of stainless braided k-type wire attached, with heat shring tubing on the end.Overall quality is top notch

Re: EGT Probes
 

Is that an Omega probe? Price?

Re: EGT Probes
 

I don't believe so, I'm not familiar with Omega, but it's made by a company called Temperature Systems International.Price should be right around, if not cheaper, than TRE's price.

Re: EGT Probes
 

Looking at the Omega site, their probe appears to be identical to the TRE one.

Re: EGT Probes
 

I have the GReddy EGT gauge and probe. Work great for me. I think I read somewhere (can't remember where, suffering from Raptorzheimers) about those exposed tip breaking off and taking out the turbine blades on the way out.

Re: EGT Probes
 

The GReddy probe reacts as quickly as TRE's, but its life is much shorter on average.

Re: EGT Probes
 

Hum, been using the same one for 3 years now, minus one year for waiting for an engine. Still works great. To each his own.

Re: EGT Probes
 

Well Shane ordered the Stewart Warner gauge for me but I am quite honestly stumped on which probe to order.
TRE: Well known & proven
Omega: Company appears to be well know & proven, Can custom spec a probe
Greddy: Well known & proven
QPR: Local, Know very little about the probe
SW: Can not find any information in either direction, The only thing I see beneficial about a Stewart Warner probe would be the commonality of manufacturer between the gauge and the probe if troubleshooting any problems ever arises

Re: EGT Probes
 

When it comes down to it, the decision will hardly matter at all. I'd either order a QPR or TRE.
