Wastegate Battle: 38mm vs 44mm vs 60mm

[1JZ_Type-S]

Loved reading this. I never even thought about the angle of my WG. Great info! I'm still pretty noob to turbo technicalities, so this will surely be a facepalm question, but....what do the spring ratings mean? Saybi have a 38mm WG with a 10 lb spring. Does that mean the WG opens at 10psi?

From what I have read the spring will open when it sees 10lbs but that is a big spring. I have a four port boost solenoid and my 3lb spring is holding find up to way over that. No creep at all
