The A-pillar will be the most looked at ones, BOOST, and Oil Pressure. Cuz a gain or loss in either will blow a car up. Then in the Din Panel will be a Fuel pressure, EGT, and Oil Temp.

wouldn't the engine blow from changing fuel pressure? are you talkin about detonation from lean/rich? if so, isn't a a/f gauge more important? Please enlighten me with your knowledge. Also explain other gauges too..(like effects of high exhause temp)</td></tr></table><span id='postcolor'>
Sorry, I was quoting in my last post, and couldn't read this post to answer.
I would like to have redundant systems in my car, just incase. Cuz I like my $3k turbo and $10k car. And I like to drive it.
Anyway, a breakdown of gauges and what they do.
Boost - Duh
Oil Pressure - If a line blows, the oil pressure will drop. If you keep driving without oil pressure, you have now cooked your turbo, and possibly seize the engine. If it increases (dunno how it would) it would blow a headgasket.
Fuel Pressure - Just like to know.
EGT - Exhaust Gas Temp. Kinda like a A/F meter, but I think it's better. An A/F meter goes by a scale of 11 - 17 or so, and is hard to tell how your engine is running. But exhaust gasses can change by tens of degrees really quickly, and thus would be easier to read and rely on. If the gasses get hotter, you are running lean. And if the temp gets colder, you are running too rich.
Finally, the Oil Temp. Since our cars are 3.5 quart + filter in oil capacity, we have one of the smallest oil capacities per liter of engine that I have EVER seen. And a turbo is going to increase that temperature by at LEAST 20 degrees Celsius. And anything over that would necessitate the use of an oil cooler, that isn't in my planned 3-month budget. And if it rises extremely fast, it is a backup, and means I am probably loosing oil from somewhere and my other REALLY IMPORTANT gauge is not functioning properly.
If you have any other questions / comments / complaints on this post, post here. Also, if you have any ideas of other gauges I would need, let me know.
