Drag racers are the extreme case - the top fuel engines are self-destructing as they cross the finish line. If they self-destruct too soon, they lose. If they aren't self-destructing, they aren't making enough power, and they lose. Those guys change pistons more frequently than most other types of drag racers change spark plugs!
Fun stuff, too. I wish I could afford to play with such things.

But, this was for just a few seconds. With the proper internal components, the EGT "redline" can also go higer.

Thanks for all the replys, I guess I was under the assumption that I shouldnt go over 1200 and have always let out of it at that temp. And dont worry I am not pulling a trailer on the high setting. My exhaust is 4 inch turbo back ATS system. The temp probe is pre turbo. I guess I will have to see what happens if I keep my foot in it a little longer to see if it tops out. I will tell you one thing this Dp tuner is awesome.
