Turbo quetion

So what is worse for a turbo, going 0-30 psi fast or holding at 30 psi for a little bit? Experts help me here. Thanks

Generally then, Holding pressure , especially that high for extended time is harder on it.

honestly getting out of 30+ psi is the worst for it. that "stall" can be hardest on a shaft, which is weak to begin with on the 11-14 6.7 turbo . I don't think acceleration of the turbo rpm is very hard on it. but maintaining 30+ psi is very hard, and getting directly out of the throttle is hard. remember , at 30 psi this turbo is at close to 180,000 rpm ! it, at that boost level , is WAY out of it's map ! they pop relatively easy at stock boost pressure of 22 psi !
