What causes rod chucking and headgasket blowing?

[Midnightclub]

Implying that rods go when the engines aren't underload. Also implying that airflow increases cylinder pressure when it is actually better to have more airflow at lower psi which will lead to lower cylinder pressures. Higher boost pressure means higher cylinder pressure and intake temperatures which strain both the rods and head gasket respectively.

I'd like you to show me exactly where i put, higher flow and lower pressure is a bad thing?

Umm.. people have had rods go when engines aren't under load, 20mph wouldn't even be 5psi when cruising. I'd also like to note that plenty of 100% standard engines have had rods go, Flynn go crawl back into your hole like a nice little troll
