How much boost pressure can a built VQ37VHR withstand?

Jwick. That is my dyno. Actually one where I was running off spring pressure only. You can see this by the way my boost drops off really bad up top. The WG springs get hot and loosen up. This is why nobody should ever run off springs alone. After I figured out my MBC it held boost evenly across the range.

I got the ball bearing upgrade. I also have that 16* timing to help spool thanks to the E.

And I second your statements of a single. Mine comes on hard and fast. I'd be shocked if an equivalent TT spools more than a couple hundred rpms faster.
