HKS BOV not "blowing"

[joe645733]

hey what's going on.

recently purchased a 1jz sc300 which is putting out 560whp.

i'm putting out roughly 26psi on WOT and i have a vacuum of...i want to say -20 inches at idle?

the HKS BOV never goes off and i am getting some surge on my brand new borg warner S363 turbo. reason i replaced the turbo was because of an oil leak from inside of the turbo. currently rebuilding the turbo. i believe this particular BOV is not adjustable, but is it possible the internals can just be seized/locked up?

anyways, because it's a brand new turbo, i'd like to address the issue to extend the longevity of this fresh turbo.

thanks, guys/gals
