not on the stock turbo. 10-12psi is where its making its max power without putting too much stress on it. Ive heard that running more than 12psi through the stock T3, wont achieve much of a power gain anyway. and that running anything higher than 14psi for extended periods will kill the exhaust wheel.
Yep i got sunburnt too, and the sun wasnt even out.
9krpm, thats a nice GT-R you have there, has an awesome exhaust note!
i took some pics, ill post em up now.
