Hey guys,
with all this speculation of whats going on w/number 4, i'm going to go ahead and installed an egt gauge on number 4. Will install the bungs on all the tubes, so i can change it around to see if its getting hotter etc. But I never installed one on my s/c cavy, so its new to me. First hurdle is to get a 0-2000 or 0-1600 sweet cobalt gauge. When i get a chance (little guy goes down for a nap) ill try to research what kind of exh. temps ranges to expect.

But any input would be great. Also planning on sticking a mech. fuel pressure gauge to the end of the fuel rail, so when 60s go in, i can see if there really is a drop.

Local guy did it here when he went to straight Turbo swap. I was also going to do this soon, so I will be talking to him about it.

 

i havent done it yet but i plan on doing it in the near future. i dont know which one to tell you to get personally id go with the 2000* gauge

 

yup ill be doing this when i get my zzp header and taking the 5v signal off it and plugging that into the aeroforce guages

 

Theres no way to run that into the hpt logger is there? Also, any idea what kind of temps we should be aiming for?

 

I have one and it gets up just above 1400*f on hard pulls it is mounted in the header about 3-4" from the head.I don't know how accurate it is cause when I shoot the header with an i/r temp gun it was reading 300*f less.I have another pyro I am going to try I just don't have any time right now to install it. I have the cobalt 0-1600 cobalt gauge and there is no ouput for logging.

 

Cool. I just bought the same gauge. And would think that there might be a 300* diff from the pyro being inside vs outside of tube temp. Also, i'm planning on putting bungs on each one so i can chance its position if need be. Is it just a 1/8npt thread or is it a special bung?

Thanks,
Nate

 

actually its totally possible to run it into Hp tuners, its done the same way as wideband as long as your EGT is based on a 5v signal which many are not , as far as temps, no idea i need do some research on it

im pretty sure though anything above 1600 isnt good

 

It is based on a milivolt signal from the pyro sensor. The gauge I got had a 1/8 pipe fitting and a tapered fitting that you can clamp on. I uset the tapered fitting and welded it to the # 4 primary pipe.Then there is a hole in the center where the probe goes through with a set screw.Kinda cheesy the old ones had an actual threaded pyro sensor. The temp output of the probe changed quite a bit depending on how deep i put it in the pipe so I tried to center it somewhat.

 

Alright, since you all have had experience with this, I'm just gonna ask here and not start a new thread.

I'm going turbo, and I'm gonna be ordering a EGT gauge soon. Now most I've found so far are 0-1600, but I've found a few from 0-2000. I know that anything over 1600 is not good at all, but what do you think would be the more reasonable one to get?

 

You can get this very accurate wideband air fuel meter and it can also log the EGT with a pyrometer, that's the one I've just ordered a couple of days ago :

i have one, it is 1.5 inches away from the head in number 4.

ultra light 2. it is a 0-2k gauge

 

how high of temps do you hit on it?

 

highest ever was 1475

 

sweet. Thanks. That makes it a bit easier to pick then

 

I am running a 0-1600 Autometer Ultra-Lite gauge, and I am usually in the 1350-1400 range, fill in here Squish if it was different!
