This thread brings an interesting question to mind.
Why don't more upgrade packages include items to raise the effective EGT limit?
I constantly see upgraded engines designed to "flow more", or to be "stronger" ... but EGT is one of the hugest limitations to engine performance. Why not and engine that can "take higher temperatures"?
There are probably one or two upgraded engine packages sporting Inconel or Nimonic exhaust valves. (Or maybe Hastalloy, or Waspalloy, those are awesome.) But you just don't see that sort of thing happening much. The only changes I usually see are Inconel turbines, Inconel wastegate valves, and occasionally ceramic coated exhaust valves. Usually though, people market ceramic coatings as reducing under-hood temps. Oh well.
Sorry for the OT. I just see so many people fighting this "wall" so to speak. 1600 is NOT a finite limit. That barrier can be moved, and it might be cheaper to move it than to lower your EGT.
