EGT probe MUST BE mounted before the turbo. 1250*F continuous use. Hotter is allowed for very short bursts (10 seconds or less usually). In testing, we have seen 2000+*F for short bursts. You have a very heavy piston there. 2000*F temps will not heat that entire piston to the point where melting starts in a very short period of time - it takes time to melt it. Think of trying to melt a block of aluminum with a blowtorch - it won't instantly burn a hole through, even though the torch is 3000*F+.

Good analogy!

Does anyone specifically make high EGT pistons for the 12V?

Are there any other drawbacks to high EGT aside from piston damage? I would love to get a set of Ti4 Al6 billet pistons and never worry about EGT again.

Cast iron would be the ticket. 2500*F+ temp capability - the cooling system would fail first. F1 technology and about $600/piston though. Cosworth could do it...we looked into it a while back, but lead time was too long for the project.
