I can hit 1450 without smoke on stock fueling.
I also seized a piston without smoke by slipping the water pump drive belt. I thought I was cool, because the temp gauge never went over 2/3ds
I have a 1.6td running about 19psi with a K14. At WOT under boost, I don't smoke...but I do see EGTs up to 1350 if I hold it there...and it'll slowly climb if I Kept my foot on the floor (which I don't, I let off at those temps). A lot of factors involved with EGTs. In my case I'm running the turbo out of it's effeciency range, which make some heat. 2.5" down pipe and exhaust, and small intercooler, all helped to get it to where it is now...but I plan to try water injection, a K24, and more fuel this year...we'll see where the EGTs end up then.
