Sorry about the noob question, I have searched and couldn't find what I am looking for.

I'm about to buy an EGT gauge with alarm, but I don't know anything about what the EGT temp means. I mean, I know hotter means lean, and cooler temps mean rich A/F ratio, but I don't know in what range it should be with a good A/F ratio. How high can it get before it starts getting dangerous?

 

Benji what burns hotter, gasoline or oxygen. Simple comparison, does NASA use 94 octane?

If you are going to buy an EGT I would buy either a SPA Egt gauge which you can find on Pegasus Racing or one like Pineapple Racing has. Generally, your EGT will be virtually completely useless to you if you already have an AFR meter (quality one). However, when you get your car tuned by a competent tuner it will help him tuner to the lowest AFR which is usually targeted in the 1600F range.

 

I'm not going to tune it or get it tuned any soon, I just want to monitor my EGT to make sure everything is working properly, and I just want to know what range is good, and what range is bad (for now)

 

BenjiRX-7,

The EGT's all depend on the sensor location. Even an inch can make a large difference in readings. One person could tell you they see 800F, another could say 1200F. Neither may be bad depending on where they mounted the sensor.

 

500$ is alot for a number that you won't understand.

About what Mahjik said, I have heard that the sensors should be placed in the exhaust manifold (one for each rotor).

 

I say just keep a eye on it, if your running good now, once the gauge is installed, make a few runs, and note the EGT. Sow add that peak number to your peak on your gauge.

You can use that for reference to what your EGT number should be. And if they get any higher, you know you MAY be running lean. Just use it sort of a safe guard.
