Exhaust Gas Temperature Gauge for tuning a carby engine

[dom14]

Hey guys,
I've been wondering,
Is it possible or does it make any practical sense to install an EGT gauge to help with tuning a carby engine?
I'm wondering EGT as a cheaper alternative to an O2 sensor-gauge kit.

Something like this.

Thanx

I think a vacuum gauge might be a cheaper option help you get close, timing light, dwell meter, or the O2 sensor not sure a egt will help very much.

Thanx mate.

I was thinking down the line of,
Too cold --> Running too rich
Too hot --> Running too lean, ??!!
I've got no idea how cold is too cold or how hot it too hot, I guess I'll be searching for typical healthy exhaust temperature readings from a properly tuned carby RB30 Patrol.
I'm not sure how to use the vacuum gauge to tune an engine. I do know how to use it for troubleshooting though.
I've already got a vacuum gauge kit, but haven't installed it yet.
I've got no idea what a dwell meter is.
O2 sensor is beyond my pocket atm. :D (Thought better to put that money into EFI in the future)
Hence the reason, I've been searching for el cheapo methods. :)

Cheers

This is the cheapest I could find when it came to the O2 sensor-gauge kit.

Bit too pricey for something that's guaranteed to not to last a long time, let along the accuracy.

Double that price, EFI RB30 engine with the wire dongle+ECU can be sourced. Just the back breaking amount of mechanical and electrical work to do the conversion. But, I prefer carbys. Only reason I consider EFI 'cos the possibility of turbo conversion.

I don't think EGt will help you much at all.

You pretty much need to know your air/fuel ratio.

For tuning a good quality wideband would def help but they are a couple of hunjy and up

If you want to experiment for $30 or so you could try the basic jobbies if you want but doubt they would have the sensitivity for full on tuning

Thanx mate, but the links above don't work. Paste it on to the "Link Icon" triggered window.
