I would like to know what all of you guys are seeing for EGTs under normal driving with stock injectors? please post up some data.

Stock or tuned?

I cruise (hwy/fwy) at 650-850°, hills at 800-1000°, WOT 1100-1200° empty, 1250° normal max towing, and 1300° up a 7% grade WOT in 6th at 2K rpms.

Normal acceleration (read slow) is 800 peak in 1-4, 850 in 5/6.
 
stock turbo?

aftermarket turbo? big, small, twins????

tuner???....stock tuning??

33" tires 44" tires?
 
Been so long I don't recall, but I know 1450° wasn't too hard WOT with a trailer. I would guess 50-75° hotter across the board than I see now, until load goes above 50% then around 200° cooler.
 
Stock minus straight pipe, I'd see 650-750 cruising, 900 on hills, and 1250-1450 WOT.

Tuned is the same, it just gets there faster.
 
I just re-read my post, I am 200° cooler now above 50% load, so stock was pretty much hotter across the board.
 
Well with stock tuning and airflow mods such as intake horn, 2nd gen manifold, he351; I'm seeing about 725 in the cold/cooler weather all the way to 875 in the warm/hot weather and this is crusing at 70mph. Under normal acceleration I'll see up to 1000 but I can never get it over 1200. I wouldn't think the airflow mods cooled it much at all if it did.
