Hi, i'm looking for some gauges at the moment and have come across a dual display Boost pressure and EGT gauge, i just can't find out what EGT is, i have tried a search on the forum but the only hits i get are members just mentioning get an EGT gauge but not explaining what it measures.

Can anyone enlighten me please ???

Thanks

Exhaust Gas Temperature I think.... Gives you an idea as to exactly how hot things are inside your combustion champer.
You'd have to drill/tap/weldabungonto your exhaust manifold to use an EGT gauge. Lotsa hassle.

yeh sounds like way too much work, i've just ordered a bog standard boost gauge :)
EGT can be used as a tuning tool. It gives you a rough idea of how rich or lean you're running. On my DSM, I'm going to be using my EGT to see how much I can lean out my fuel trims with a piggyback ecu controller. Its a little more accurate than tuning with an A/F meter
It's different information than tuning by AFR, it's no replacement for good AFR data (as in, wideband). It's a nice tool to have, but it is a lot more painful to install than most gauges, and there's other ways to monitor your engine health that can be more insightful (knock indicators, wideband O2), mostly because there's too many factors that can affect EGT to use it as a bible.
