You need a 12vdc gauge that reads at least to 1700degF (927degC).

I wasn't very impressed by that article. See the discussion here:

In a few more decades he may very well become the educated person that he has argued against since day one.

That's also how an AFR gauge is supposed to be used.

 

looks like Pineapple racing has the best EGT gauge for the money.

 

I don't know how much he was using them for tuning, but I know he was using it to demonstrate the cooling abilities of methanol injection.

 

I have the Pineapple racing EGT, although not installed yet. I am very impressed with the quality of the components- it is truly aircraft quality.

The EGT thermocouples are installed on a Greddy manifold- one of each exhaust outlet near the manifold flange.

 

hmm thanks for the link.
