Anybody got a ballpark figure on what our max EGT is on this motor?
Preferably what normal is and what melt down is lol

Egt?
Exhaust Gas Temperature.

I like my turbo and wanna know what it normally runs at approx.

wanna buy me some gauges for Christmas so I can tune in the spring? I need a wideband, EGT, Oil temp, oil pressure, and any other gauge u think might come in handy lol 
cmon u know u wanna help me murder some cars on the track next year lol

I'll try and find out for you.

I couldn't find anything LNF specific, so I'll just assume that its just like any other car on the road; although I have a feeling the the D.I. might change things up a bit. I'll try and find out more on that though.
800* or so is what it should idle around.
1200* or so when cruising at "city" speeds
1400* or so when cruising at interstate speeds.
1550* or so when WOT at the top of 3rd and 4th.
Ok sweet, wasnt sure if there was a difference for forced induction or anything, thinking I'll get a 2k *F gauge just so I'll have a little buffer at the top end.
Mainly wanted to know so I have an idea of how the turbo is doing, and have a warning before she melts down. Not sure what temp that would be at but I figure its one of the more important things to monitor along with oil temp.

You shouldn't need anything over 1600*. That's pretty fkn hot and on most cars that I know of, that's The Danger Zone.

we should try looking for MS3 EGT's, should be very similar to what we should be running.
Hmm good call White, I'd be all over looking if I actually had my laptop here with me. Stuck on Cobizzle's cause Cobalt Tom's cat ate the powercord lol

Well, they shouldn't be that different. EGT is going to be effected by a couple different things such as AFR, Timing, and Boost Levels. So no ones Temps will be exactly the same.

The EGT values reported by the ECU are calculated I'm told, but I went catless because tuned I saw temps in excess of 1850*f logged in HP Tuners during a hard 4th gear pull at ~22 psi boost. Even if they aren't close to real values, they scared me. This is with the Cat Protection off so it didn't go very rich (.71 lambda) during the pull. I run .88 lambda WOT.
I had a ZZP catted DP on it, but thought it'd become a solid mass at some point.

errr...i do stoichiometric could you convert the lambda for me lol

14.7 X Lambda = AFR,
Stoich = 1.0 Lambda
.88 X 14.7 = 12.94 AFR
Stock Lambda is leaner than that by a long shot in the midrange and cruise is 1.0 Lambda or 14.7 AFR.

so what your saying is that you'd absolutely recommend a catless DP vs catted if the person is going to tune/upgrade?

see that's why I convinced him to come here
we need guys with this kinda info on here

If you don't have emission testing where you live, or if you are willing to put the cat back on when needed, yes. Most aftermarket cats are good for 1800 - 1850*f EGT's depending on construction materials. Like I said, I don't know how close the estimates from the ECU are, but the catless DP flows better anyway.

catless dp sounds like d cups
que?
