You guys scare me.

1450 deg F at WOT should be your target max EGT. These are not factory forced induction rides, with beefier cooling systems, forged pistons, valves/valvetrain, etc, designed for all the excess thermal load. Factory FI cars can deal with higher EGTs because they are designed to get rid of all that extra heat.

None of my turbo dodges have forged pistons. And a few share the same cooling system as my N/A cars. It's all about the tune. The only differences in my turbo cars and my N/A cars is the composition of the exhaust valves and the Static compression of the pistons. My Turbo 2.5L has a static compression ratio of 7.9:1, while the N/A 2.5L has the 9:1 ratio. My 3.0L is even 8.85:1 CR.

The turbo cars exhaust valves are made of stainless steel to handle the excessive exhaust temps before the turbo. All else is equal between the two.

If you aren't detonating/pinging, 1600 degrees won't hurt anything. Its the detonation that tears things up...
