Thats a chilling description about exhaust valve creep, Forced... I think I won't be pushing anything over 1200 for any amount of time thank you very much...

pre-turbo sensor W/ big A/W IC, no rack limiter, GM 3.8 airbox, T3-45@16-20psi:

highest ever: ~1050°F WOT, loaded down, up a hill for about 5min
around town: 450-650°F
highway: 650-850°F (depending on speed and grade)

I bet with no rack limiter if I found a way to lug it down around 2500rpm WOT I could get it to make higher EGTs, but the way it is it just aint happening. I'm sure they will go way up when I make it rev 5K+ and crank the TC...
